You must be looking forward to a long vacation and wondering how to manage the power backup system in your home. Bad weather conditions or other factors can cause interruptions in homes, making it difficult for people to use electrical appliances, light up their homes or for heating and cooling systems. With today’s world becoming dependent on technology, power supply that once only provided electrical energy for lights, appliances, and heating and cooling systems has to now additionally power computers, security systems and smart-home automation.

Therefore, it is important to have an emergency backup power system for your home that would allow your devices like home office computers, telephones, refrigerators, medical devices and security systems to have continued access to electricity. Moreover, due to this additional usage of electric services, there have been prevalent power outages in many parts of the United States. Of course, simple candles would help light up homes for a couple of hours during power outages, but would not be of much use in other basic necessities like heating and cooling systems, computers and security systems.

It is always recommended to have a solid power backup in place well before experiencing or going through the hassles of power outages. Frequent power fluctuations can also affect the quality and efficiency of your basic needs like refrigerators, lighting, computers, attic fans, heating and cooling systems, and security systems. All this unnecessarily adds up on to the costs for your home. Let us look at the pros and cons of the commonly used battery backup units and generators by homeowners.

Battery Backup Systems

Battery backup systems are very convenient, especially when you are away from home for a while. They may be a little more expensive than generators, but are worth the investment. They consist of batteries that are deep-cycle storage cells and come in banks or groups. An inverter is necessary for a battery backup system in order to convert direct current (DC) to alternating current (AC) for powering homes.

Advantages:

• They are a better alternative to generators in terms of efficiency.
• They include safe indoor installation.
• Batteries do not make any noise.
• Backup power systems can provide immediate electrical power to critical loads during natural or other disasters.

Disadvantages:

• The durability of battery systems is limited, since they provide power only when charged. One example is the mechanism of how a charged battery can operate a pump for days and then get recharged automatically. Generally, a pump sentry interface is set up between the pump and the AC electrical supply. During the supply of electricity, the pump sentry charges a battery and monitors the power line for any power outages. When power fails, the power that is stored in the battery is converted by the power sentry to AC power. This power is utilized in the absence of electricity. When the electricity is restored, the AC utility power is used to operate the pump and simultaneously the battery is recharged in order to facilitate the next power failure.

Generators

The difference between a generator and a battery backup is that a generator creates new energy, whereas in battery backup systems the chargeable batteries control and store the existing utility power for any emergencies that may pop up at any point of time. The fuels used for household generators are gasoline, diesel, propane and natural gas.

Advantages:

• They are affordable.
• They are portable, convenient and can be used for short periods.
• Maintenance is easy.
• Propane and natural gas are environmentally and economically sound fuels.

Disadvantages:

• Generators are usually very noisy.
• The cost of fuel is expensive.
• Stored gasoline and diesel can cause fire hazards and become gummy and contaminated over time.
• It causes pollution due to smoke and smell.
• Generators are not very compatible with cold weather conditions.

As you can see, battery backup units have an overall advantage over generators. However, it is recommended to go through the technology and cost involved in different types of battery backup units before buying one to suit your home needs.

Masonry construction has always been known for its durability, as it is able to sustain harsh conditions depending on the weather and geographical location. It also gives an attractive appearance and requires relatively low maintenance. The use of materials in masonry construction ranges from stone foundations to brick walls. Since some masonry foundations tend to be susceptible to accelerated deterioration, they were either painted or covered with stucco for protection. In addition to the weather and location, water can be a primary cause for the deterioration of masonry foundations.

The common causes of masonry deterioration are:

•Climatic Conditions: Excessive moisture within masonry foundations due to extreme hot and cold climatic conditions causes the masonry to expand and contract at different rates, weakening the masonry’s bond with the mortar.

•Uneven Settlement: Uneven settlement, deterioration of materials like rusting iron anchors or rotting window lintels, washing out of internal bonding and mortar and other structural problems, as a result of water flowing through walls.

•Weathering: Mortar that is generally used to help in the freeze-and-thaw expansion-and-contraction of masonry walls is washed away with heavy rains, wind and pollution.

•Design and Materials: Poor design and inappropriate materials used for masonry construction under different weather conditions and geographical locations can lead to several foundation problems.

•Exterior Maintenance: Proper maintenance of the exterior of a masonry construction will minimize most of the problems that lead to masonry deterioration. It is essential to install properly functioning gutters, downspouts and flashing to avoid dampness, water accumulation at foundations and growth of vegetation due to water penetration.

The following are some of the significant problems that come along with masonry construction due to moisture deterioration:

1. Severe climatic conditions like extreme temperatures, wind speeds and directions, high humidity levels and heavy snow can deteriorate masonry foundations, including cracking, spalling, surface erosion and efflorescence. Violent waves, debris carried by waves and heavy deposits of ice on masonry constructions can damage the strength and features of the foundations.

2. Severe freeze-thaw cycles can cause damage from frost action if moisture is trapped in walls or there is lack of total structure ventilation. In addition, they can also cause condensation that will encourage mold growth.

3. Locations by the sea can lead to efflorescence on the masonry due to high salt content in the air.

4. Industrial areas cause acid rains that can damage limestone, marble, sandstone and concrete.

5. Foundations and walls are usually immersed in water for a long time during natural calamities like floods and this can lead to damage.

6. Absorption of water depends on the type of soil and influences water drainage around the structure. Excess water in the soil leads to dampness, giving rise to issues with the foundation.

7. During heavy rains, puddles of water form around buildings that do not have proper slopes. This may lead to localized ground saturation and water penetration.

8. There are possibilities of water penetration in brick or stone foundations that are laid close to the earth.

9. Trees and vegetation like ivy and creepers prevent proper drying of masonry foundations by allowing water penetration in the joints which lead to erosion.

Therefore, it is important to identify the cause of moisture deterioration in masonry constructions in order to fix the problem and avoid further damage. Alternative solutions are waterproofing the foundation to prevent leakage, replacing cracked bricks and stones and repointing mortar joints. Consulting a skilled masonry craftsman or inspector will help in diagnosing the problem and bring about quick solutions. At Keystone Basement Systems, we specialize in foundation structural repair and waterproofing services, which come along with experienced professionals.

In our previous article, we discussed about the different causes of basement odors and where they originate from. But how do we get rid of these musty odors to improve our basements in the home? Let us look at some of the effective ways of dealing with these unpleasant and uncomfortable odors in the basement.

1. Cleaning the basement: Cleaning your basement will get rid of most of the musty odors, mold and mildew, dampness and humidity existing in the basement. Choose a sunny day to remove all the furniture and carpets in order to sun-dry them and also deep-clean the carpets. Sweep and dust all around the basement to remove dust that is the primary cause for allergies and other respiratory problems. It is recommended to use a disinfectant to clean the walls and floors, so as to get rid of the musty odor due to mold and mildew growth that are usually found under carpets, behind panels and behind perimeter walls. Throw away all the unnecessary stuff from your basement as they are favorable to the growth of molds and, in addition, you can create space in the basement. Arrange clothes, books and furniture in a neat way by keeping all clothes in the wardrobe, arranging books in stacks and minimizing the furniture in the basement.

2. Waterproofing: Cracks or leakages in the walls are usually caused due to dampness. The dampness could be either due to unfavorable climatic conditions, improper drainage system and excessive humidity. Cracked walls should not be left as they are, and should be either sealed or patched as soon as they are identified. Leaving a cracked wall unattended could worsen the situation by widening and spreading all over the wall. Dehumidification is essential for leaking walls, since it helps in drying the wall. These walls can be cleaned with trisodium phosphate, a hard surface cleaner. Once the walls dry, seal them with a latex concrete sealer to avoid further leakage and musty odor.

3. Dehumidification: Humidity is another primary cause for smelly basements. A dehumidifier can help in controlling the humidity in your basement. Attaching a hose to the dehumidifier will get rid of the excess moist air in the basement, leaving no space for the growth of molds that lead to the musty smell. It is also essential to keep in mind the type of dehumidifier you choose for your basement and should be based on the efficiency and size of your basement.

4. Ventilation: This is undoubtedly one of the most important factors to consider when getting rid of basement odors. On a fine sunny day, just open all the windows in your basement and switch on your exhaust fans to allow circulation of fresh air within the basement from outside. Cross-ventilation is also very important in removing humidity and stagnant air that gets accumulated in the basement.

5. Drainage system: Ensure that you install both a proper interior and exterior basement drainage system to prevent condensation that can lead to dampness. Wrap pipe insulation around the basement pipes to avoid condensation from building up on them. Leaking basement walls can trap water and increase humidity in the basement. Ensure that the ground slopes and downspouts are extended around six feet away from the house. You can also read our blog article on basement drainage systems for more information at http://blog.keystonebasementsystems.com/?p=980.

Apparently, there are also some home remedies that could be useful to get rid of the musty odors in your basement too.

• Baking soda is effective for neutralizing odors and absorbs moisture and so you can either leave it open in a container or sprinkle a little on your smelly carpet and later vacuum it.
• Vinegar is a household product that helps in neutralizing odors, including those left behind by pet accidents and skunk sprays.
• Citrus fruits like lemons and oranges leave a pleasant smell behind and can be used as air fresheners.
• Charcoal and cat litter help in absorbing moisture.

You might be making use of your basement for utility purposes such as your air-conditioning systems, car parking area, fuse boxes or electrical distribution systems. This means that your basement is not completely utilized like your other rooms in the house. When you enter your basement for these purposes, you may have noticed an unpleasant smell in spite of taking good care of your basement. Basement odors are quite common with regard to the maintenance of basements. Let us look at some of the important factors that lie behind the musty odor that bothers you most of the time.

Causes of Basement Odors

Dampness

You must be wondering how a closed area like a basement would invite chances for dampness. When the level of humidity is high, the amount of moisture increases in the atmosphere. The condensation of moist, warm air on cold interior wall and floor surfaces is more than enough to create dampness in your basement. Wet walls, foggy windows and tiny droplets on cold surfaces are good signs of high levels of humidity. When air is able to hold water vapor at a particular temperature, the relative humidity is 100%. If it goes beyond, that is when condensation takes place, causing dampness.

Mold and Mildew

The environment in a damp basement is suitable for the growth of mold and mildew. Molds are a type of fungi and ubiquitous in nature and are therefore found both indoors and outdoors. Climatic conditions such as warm, damp and humid weather are favorable to the growth of these organisms. Mildew has the ability to break down cellulose material and release volatile organic compounds (VOCs) that result in the musty odor in basements. Mold growth is usually very common in basements and can be seen as black spots on wood furniture, carpets, drywalls, organic ceiling tiles, paper, cloth, cardboard and anything that is made up of organic material, causing rotting and damage. The presence of mold and mildew in the basement gives a musty odor which leads to various health-related issues. The mold spores that are formed on damp surfaces affect the immune system when they enter the respiratory tract and cause symptoms like breathing problems, congestion, headache, asthma and allergies.

Stagnant Air

A basement or a crawl space is usually a closed area and is not frequently used as compared to the other rooms in the house. This reduces the amount of air entering into the basement. A musty odor in the basement develops due to lack of circulation of air. This can be found out by opening the windows in your basement and switching on the exhaust fans on one fine day to allow air circulation. If the bad odor in your basement does not exist, then you have the answer to your problem!

High Humidity

Your basement may have the perfect air circulation and may be clear of any mold and mildew growth, but do you still experience bad odor? Well, humidity could be the reason and does play a vital role in a smelly basement which occurs due to climatic conditions. High levels of humidity in the basement (above 50%) create breeding grounds for the growth of mold and mildew. Hence, before the construction of your basement, it is important to look into the aspects of moisture, humidity and air circulation.

Water penetration

The chances of water penetration in the basement are always high, since it is located below the ground where water gets accumulated. There are basically two ways in which water can enter into the basement, through the foundation walls and the basement floor. When water gets soaked in the soil, there is always pressure of the heavy water to push through the foundation walls. If there are any cracks or joints on the walls, then water is sure to pass through depending on the quantity and pressure of water against the walls. Stains on the concrete, paneling of a finished basement and efflorescence are common indicators of water penetration. Corners of basements are also popular for water penetration caused by the discharge of rain water from the rain down spout in this area.

We have already discussed about the importance of dehumidifying your home or basement. However, it is also essential to know how these devices work in order to avoid any hassles. Humidity is one of the primary reasons why we end up installing dehumidifiers in our homes, especially in closed areas like basements. Moreover, if you live in the equatorial or coastal regions, you are sure to experience humid conditions most of the time.

Humidity is a result of relative humidity where moisture is suspended in the air. A dehumidifier is a device that helps reduce humidity in any building or room by removing moisture from the air. Dehumidifiers play a vital role in preventing mold, bacteria and biological  allergens, musty odors, and furniture, carpeting, storage box mildew damage that arise when humidity levels are above 50%.

Principle

The principle that lies behind the dehumidifier is simple. It works on the same principle as the freezer, refrigerator or air conditioner. For example, on a hot day under the scorching sun, when you have a cold drink you can see tiny droplets of water forming on the surface of the container due to a process called condensation. In the same way, a dehumidifier condenses the moisture present in the air with a fan that blows the warm air onto coils of cold metal. The condensed moisture is then collected in a bucket or holding tank in the form of water. The cold air is then blown onto the warm coils and brings the temperature back to normal.

Components

A basic dehumidifier consists of the following components for normal functioning:

1. Fan Compressor: It is the quiet motor of the cooling system that is found at the bottom of the dehumidifier and helps in cooling the dehumidifier coils.

2. Condenser: It is a series of finned coils, similar to a radiator, and located near the circulating fan.

3. Evaporator: This is also a set of coils located behind the dehumidifier and just above the water-collection container. It captures and collects heat that is generated by the cooling process.

4. Reservoir: This is where moisture that is condensed from the air is collected.

Most dehumidifiers also have a humidistat that helps in setting the desired level of humidity. A humidistat consists of a sensing element and a relay amplifier. A sensing element has two alternate metal conductors that cause electrical resistance when there are variations in relative humidity. The relay amplifier measures the resistance and is responsible for the utilization of the dehumidifier based on the measurement.

Methodology

The fan compressor in the dehumidifier extracts the moisture from the air into the dehumidifier. As we all know, warm air can hold more moisture as compared to cold air. When relative humidity is high, the amount of moisture in the air is also high. The warm air is drawn toward the cold coils in the dehumidifier where condensation takes places by a condenser. The amount of air that is moved by a dehumidifier is measured in cubic feet of air per minute (CFM). Hence, when the CFM level is high, it becomes easier for the dehumidifier to remove large amounts of moisture. The size of a dehumidifier is also important in determining the reduction of humidity. The smaller the dehumidifier, the lesser the capacity to remove moisture. After condensation, the water is collected in a holding tank or reservoir, which is either attached to or separated from the dehumidifier.

It can be quite difficult to extract moisture from closed areas like basements and crawl spaces, since the temperature will be low. In such cases, it is wise to choose and buy a dehumidifier that is specially designed for such areas. In an environment where relative humidity is above 50%, the function of a dehumidifier becomes easier due to large amounts of moisture present in the air. On the other hand, an environment with low level of humidity will require a powerful dehumidifier to accomplish the task.

Types of Dehumidifiers

1. Mechanical or Refrigerative Dehumidifiers: It absorbs moisture over a refrigerated coil with a small fan.

2. Desiccative Dehumidifiers: Desiccant materials are used by initially expose them to high relative humidity in order to absorb moisture. The materials are then exposed to low relative humidity to extract moisture from them.

3. Air Conditioners: They decrease the temperature in the room in order to condense and liquefy the moisture in the air.

On a cold winter morning or evening, you must have felt tiny droplets of water in the atmosphere or for that matter seen water droplets in the air in the form of fog on cold beverage containers during the hot season. But have you ever wondered what lies behind this natural phenomenon? The answer is dew point, which we will discuss in detail in this article.

Dew point, or otherwise better known as dew point temperature, is the temperature at which the liquid and gaseous phases of a material present in a gas, such as water in air, are in equilibrium at a given gas pressure. In the case of water, the temperature at which both evaporation and condensation of water take place are the same. An interesting point to note about dew point is that it is related with evaporation, condensation and relative humidity.

How Does Temperature Affect Dew Point?

It is a known fact that warmer air can hold or suspend more water vapor in the air than cold air. When the air cools down, it naturally loses its ability to hold moisture in the air. Dew point temperature is also known as the saturation temperature of water vapor in the air, the reason being that when the temperature is lowered from the saturation temperature, water vapor condenses faster than it evaporates. On the other hand, when the temperature is increased from the saturation temperature, water vapor evaporates faster than it condenses. At the saturation temperature, the evaporation and condensation rates of water vapor in the atmosphere are at equilibrium.

Dew Point vs. Humidity

As mentioned in our previous article, relative humidity is the amount of moisture or water vapor that is suspended in the atmosphere. Dew point and humidity have been found to be related and are dependent on the amount of water vapor in the air and the total amount of water vapor that the air can hold at a given temperature. This is the main reason why you see tiny droplets of water on cold surfaces during hot weather conditions.

When relative humidity increases, the dew point temperature is closer to the current air temperature and when relative humidity decreases, the dew point temperature is at par with the current air temperature. When dew point temperature and real temperature are the same, relative humidity is 100%. At this point of time, fog, mist, dew and clouds start forming due to condensation and this means that the air is holding 100% moisture.

Basic Points to Know about Dew Point

• Dew point temperature can never be higher than the current temperature.
• When the temperature is the same as the dew point temperature and then starts falling, the dew point temperature must simultaneous decrease.
• The amount of moisture in the air increases with increase in the dew point temperature.
• Relative humidity of around 100% is an indication of dew, frost, fog and rain.
• Regions around the Equator experience high dew points, whereas the desert and polar regions experience low dew points.

Applications

• Heat transfer by convection
• Combustion of fossil fuels and combustion engineering
• Drying of paper, cardboard, plastics, wood, tobacco, leather, printed goods, textiles and grain
• Energy efficiency in chemical manufacturing processes
• Prevention of corrosion in iron, steel and other metals

Humidity

In order to understand relative humidity, let’s look at what humidity is all about. The term humidity is mainly used for the moisture that is present in the atmosphere. Understanding humidity in terms of geography, water in the rivers, lakes, oceans and other water bodies is absorbed by solar radiations when heat is generated by a process called evaporation. This process results in large amounts of water evaporating into water vapor present in the atmosphere. Water vapor condenses in the form of rain, snow and clouds by a process called condensation. You can read more about condensation in our previous article, “What is Condensation?”

Relative Humidity

Researchers have tried to find out different ways to measure humidity in order to analyze significant factors like climatic conditions in different regions. Among the different ways of calculating humidity, relative humidity is the most commonly used method. Relative humidity is basically the amount of water vapor or moisture that is present in the atmosphere. It is the amount of water vapor present in the air at any given time relative to the amount that is required to saturate the atmosphere,

i.e., Relative Humidity = actual vapor density/saturation vapor density × 100%

If the presence of water vapor goes beyond saturation, it condenses as dew. Relative humidity increases when the unsaturated air is cooled. When the air reaches saturation point, relative humidity is 100%.

Considerations When Measuring Humidity

Have you ever thought why it is essential to check the level of humidity? There are basically two reasons, maintenance of hygiene and energy efficiency. Lack of control in humidity leads to mold formation, corrosion and persistent condensation on cold surface. The ideal and maximum level of humidity is between 30 and 40%.

Humidity occurs as a result of fluctuations in temperature. For this reason, it is necessary to consider temperature while measuring relative humidity. As mentioned earlier, temperature is responsible for saturation vapor pressure. High and low levels of humidity have a significant effect on relative humidity, as well as saturation pressure. Therefore, the exact temperature makes the comparison in humidity measurement values easier.

Another factor to take into consideration when measuring relative humidity is the location and stabilization. Short distances can also have variations in relative humidity and it is always wise to have patience till the conditions are stabilized, including temperature.

How Do We Measure Humidity?

There are a number of devices that can be used to measure humidity. Relative humidity can be measured by the following instruments:

1. Sling Psychrometer: It consists of two thermometers, a wet-bulb and a dry-bulb thermometer. The thermometers function on the basis of the evaporation and cooling that takes place in the atmosphere. When evaporation occurs, the temperatures in both the thermometers show different values and their differences are noted down (wet-bulb depression) to calculate relative humidity. On the other hand, these thermometers would have the same temperatures if there was no evaporation.

2. Hair Hygrometer: This device is based on the calculation of the differences in the length of strands of hair during humidity. As the hair becomes longer, the humidity also increases.

Importance of Relative Humidity

1. Climate

Relative humidity does play a vital role in climatic conditions, especially when there is a fluctuation in temperature which decides human comfort, health and safety, and technical requirements of machinery and processes.

2. Comfort

Human beings tend to be quite uncomfortable during seasons when the relative humidity is very high. Humid conditions make people perspire to a lesser extent than dry weather conditions. Hence, we feel much warmer during high levels of humidity than lower levels of humidity.

3. Buildings

In order to maintain the temperature in the surroundings, there should be a control in relative humidity. High temperature and low humidity leads to rapid evaporation of water that result in dry soil, quick drying of clothes, dry sweat and shrinkage of wooden furniture that could damage the paint. However, high temperature and high humidity leads to slow evaporation of water which leads to growth of mold and mildew, corrosion, decay and other damp-related issues. Similarly, relative humidity needs to be controlled in buildings such as factories, hospitals, laboratories and other facilities using devices such as humidifiers and dehumidifiers to avoid such issues.

4. Vehicles

You must be wondering as to how vehicles would get affected by humidity. High humidity inside the vehicle can lead to condensation on the windows while driving and electrical problems. Airliners, submersibles and spacecrafts are also prone to condensation, corrosion and health problems such as drying out of mucosa, dry skin and sore eyes.

Condensation is the conversion of water from its gaseous state into its liquid state. There is always some amount of moisture present in the air. During cold weather conditions, the moisture present in the air condenses into tiny droplets of water. In fact, the air that you breathe out can be seen on a cold winter morning. Condensation can also occur on those hot, humid summer days where you would need an air conditioner to cool your home. This may result in hazy windows due to the air conditioning.

Household activities such as cooking, washing and drying clothes are responsible for the excess moisture present in the air within your home. An average family creates around 20 pints of water vapor per day. This can be usually seen in the form of fog, mist, dew or frost in the atmosphere and plays a significant role in the formation of clouds, rain and snow.

Condensation is a result of the fall in temperature of vapor even below its saturation temperature. When warm air rises in the atmosphere and cools down, it loses its ability to hold the water vapor in the air and hence the excess water vapor condenses to form cloud droplets.

What does condensation have to do with basements? Well, it has quite a lot to do with basements. The moisture that forms as a result of condensation can cause rotting window frames, peeling wallpaper and mold on walls, carpets or clothes. This phenomenon occurs where there is no adequate air circulation. You may have noticed mold on your windows, walls, ceilings and furniture a couple of times, especially during the winter season. This also comes along with stale air that gets accumulated within the basement due to lack of ventilation. All these factors lead to aggravation of illnesses such as asthma and bronchitis.

What is the difference between condensation and dampness?

Dampness can be a result of condensation. As mentioned earlier, condensation occurs during cold climatic conditions when the water vapor is surrounded by cold temperature and the moisture content of the air is high. This leads to the growth of mold and mildew which may due to lack of air circulation and insulation. Dampness can also be caused due to other reasons such as leaking drainage pipes, wastes or overflows, cracked walls and ceilings, leakages from the roof where tiles are missing during rains and defective damp course or no damp course.

Condensation in the basement can be caused by the following reasons:

(1) Lack of ventilation, especially during the summers
(2) Lack of insulation, especially during the winters
(3) Inadequate heating in the basement

How to Reduce Condensation or Dampness in the Basement

(1) Allow moisture to move out of your home when cooking, washing or drying clothes and heating by closing doors to avoid circulation of moisture and opening windows to let out the moisture.

(2) Make sure that you ventilate your home to remove moisture by opening windows, using exhaust fans in the kitchen and bathroom to let out the damp air after frying or taking a hot shower, installing air vents wherever possible, cutting breather holes in cupboards and wardrobes and installing ventilators for windows.

(3) Insulate your basement by air sealing, installing insulators in your walls, dehumidifiers, which will keep your rooms warm and simultaneously prevent the entry of moisture and hence avoid dampness.

(4) In order to remove mold and mildew from walls, use a fungicide. Clothes and carpets affected by mold can be dry cleaned and shampooed, respectively. Mold and mildew creates a high risk of respiratory problems and gets worse if disturbed by brushing or vacuum cleaning.

(5) Get rid of any kind of moisture immediately by wiping any surface moisture to avoid room for any damage.

(6) Fungicidal paints for the walls will also help in preventing growth of mold and mildew.

So next time you think of basement condensation, you know exactly what to do!

Basement drainage systems can be a solution to all your basement problems such as water leakages, bad odor, stagnant air, furniture damage, mold and mildew. These drainage systems can either be installed in the interior or exterior of your home. Different methods are usually implemented for both interior and exterior drainage systems depending on the cause of damage. The following are some of the reliable options you could use to install a drainage system in your home.

1. Interior Basement Drainage System

Most people opt for an interior basement drainage system for a number of reasons that include the affordability to install one inside the basement than outside, the convenience of the job, the minimal time required for installation, no hassles on the availability of services and reliability. Some useful ways of drainage systems that you can consider are:

(a) Concrete walls: An interior drainage channel adhered at the base of the wall and the floor slab is ideal in situations where water tends to enter the basement. Installing the channel is a cost-effective approach, especially for concrete walls with cracks, and works by simply by collecting water into an airtight sump with the help of another channel that is placed on top of the slab. The water then flows through a trap to the sump basin. Although this method is effective for concrete walls, it is not very helpful in the case of masonry walls because water remains in the block cores at floor level and the water level is only lowered to the top of the slab.

(b) Masonry walls: For masonry walls, installing a drainage channel at the base of the wall on top of the footing gets rid of moisture problems inside the basement because it drains the block cores completely. For this reason, holes are drilled at the base of every block core to permit drainage. The concrete along the slab edge should be removed and replaced for this approach. The drainage is connected to an airtight sump where water is collected.

(c) Perforated drain pipes: A perforated drain pipe installed inside the perimeter of the footing by removing and replacing concrete at the slab edge allows free drainage of the wall into the drain pipe. A dimpled plastic sheeting is placed at the base of the wall and beneath the slab edge. The drainage is connected to an airtight sump where water is collected. This method gives better results when combined with an active soil gas management system that connects with the sump and perimeter drain pipe.

2. Exterior Basement Drainage System

Exterior basement drainage systems have been found to be costlier than interior drainage systems since there is a lot of work, time and external causes such as weather conditions involved. On the other hand, they are essential for preventing exterior foundation damage. Although exterior drainage systems are expensive and time-consuming, people concerned about property and equity maintenance will have long-term benefits. A look at some exterior drainage system approaches:

(a) Grading: One would wonder as to what the soil has to do with a drainage system. Proper grading of the soil around the house would eliminate the entrance of water into the basement. Creating slopes would drive away water before it reaches the basement walls. In fact, this method would not even require a basement drainage.

(b) Open drain: Open drains which are just shallow trenches that are lined with cement or plastic and held together with pebbles or gravel help in collecting water and discarding it before it reaches the basement.

(c) French drain: A French drain is a trench that is covered with gravel or rock and basically redirects surface and ground water. This is useful for exterior drainage systems because the French drain that consists of a perforated pipe not only gets rid of water entering the basement, but draws water out of the soil before it soaks into the soil. The depth of the trench can range from 2-3 feet to 5-6 feet deep. However, lack of maintenance can lead to clogging of these trenches from sediments in the ground that will force water into the basement.

(d) Gutter downspouts: Gutter downspouts that are extended at least ten feet from the house and preferably connected to a rainwater collection system can work out as a reliable source for drainage.

Disadvantages of Interior Basement Drainage System:

1. Extensively finished basement – The basement has to be properly insulated and sealed with appropriate materials which make the process expensive and intrusive. Improper installation can lead to moisture and mold problems and the interior drainage system may require non-invasive termite detection systems in termite-prone areas.

2. Excessively thick basement floor – Thick basement flooring can make the process impractical and, in some cases, impossible to install.

Disadvantages of Exterior Basement Drainage System:

1. Property line constraints – People may not own enough land surrounding their homes for an excavation trench and an area for a machine to operate. Moreover, digging or excavating by hand can be a tedious and expensive process. Excavation can also get difficult in different seasons like the spring if the area has a high water table and is impossible during winters.

2. Safety – Some problems occur on hillsides that will not allow safe excavation. This can lead to extensive damage in terms of landscaping.

3. Urban areas – Some areas are so densely built that outside measures are not practical.

4. Obstructions – Some homes have additions like paved carports, gardens, trees and fences that overhand the foundation drainage and thus make it impossible to excavate those areas rendering external methods inadequate.

5. Utilities – Some areas have underground utilities that make external excavation difficult or impossible.
