    What are the stages of waterproofing?

    There are two categories in waterproofing.

    1. Preconstruction waterproofing

      Preconstruction Waterproofing is the essential precautionary measure to avoid water seepage through ceilings, walls or from the basement. Some of the methods that can be used in preconstruction waterproofing are Concrete Admixtures, waterproof cement, Integral waterproofing, Expansion Join treatment, and waterproof concrete films.

    2. Post construction waterproofing

      Post construction waterproofing is the techniques that work on water leaking ceilings, walls or basement to prevent further damage. These are mostly of synthetic coatings. When you find dampness or crack on the wall or ceiling, find the cause of the damage. Make sure to locate where the water is coming from. If water from the water tank infiltrates inside the ceiling of your house, you will need to waterproof the tank too. In this case, the damaged surface is cleaned and pretreated to avoid tearing of coatings. Some of the post-construction waterproofing methods are Brick bot Coba, Bitumen coatings and membrane.

    When should you waterproof your house?

    It is also important to do this waterproofing before the monsoon arrives because the process takes 2-3 weeks to dry. Some of the coatings such as polyurethane and epoxy coatings are moisture sensitive and decreases its durability. Torches are used to dry the surface to make it moisture free before the waterproof treatment, but it will cost you additionally. So, it is better to start waterproofing your house soon before the season starts.

    Five essential parts of the house that needs waterproofing treatment

    The waterproofing contractors are the professionals who seal your house from water to protect it from the damages caused by it. The waterproofing contractors in Bangalore incorporate high-grade materials manufactured from multiple waterproofing companies. Most of the buildings in India are prone to damages caused by water which adversely affects the structural strength of the buildings. Waterproofing makes the structure resistant to water protect the building. Some waterproofing chemicals are mixed with the concrete during the construction process to waterproof the building completely. This technique is known as integral waterproofing. Many other waterproofing treatments include bitumen waterproofing methods, acrylic waterproofing methods, waterproof paints, and cement.

    The first step in waterproofing solution is to find where the water comes from. It is necessary to identify that to keep the water away from damaging the home. There are a few ways by which water can enter through the parts of the house. One needs to waterproof all these parts of the house to escape from damages caused by water. Waterproofing also increases the value of your house.

    1. Foundation

      Even though your foundations are strong enough, they may develop cracks and allow water to pass through. Concrete is naturally porous which makes it easy for water and moisture to enter. When there is water infiltration in your basements, there are many sources from which the water can enter. It may due to increasing groundwater level or there may be flooding near your city which indirectly increases the groundwater of your area. In some cases, the water may be due to the leakage from the sump tank or from the broken drains. To waterproofing the basements or foundations, one needs to identify the source of the water before planning for waterproofing. Accordingly, you may need to waterproof the basement floors, interior walls or the exterior walls.

    2. Terrace

      In India, terrace waterproofing methods are mostly predominant than the other ones. In a tropical country like India, the buildings are exposed to extreme weather conditions. These enhance crack formation in the buildings which decreases the structural strength. The terrace is the part which is most affected by these climatic changes from heavy rains to hot summers. There are many terrace leakage solutions available with the waterproofing services in Bangalore. There are two possibilities of water seepage through the terrace. The water may come from the overhead tank or stagnant rainwater.

    3. Exterior walls

      Similar to the terrace, the exterior walls are also exposed to severe weather conditions. The rainwater infiltrates into the wall, resulting in wall dampness, blistering of the wall paint and mold growth. The mold growth brings a bad odor, exploits the interior and exterior look of the house and may also cause health issues. Waterproof paints work great for exterior walls which enhances the exterior look too.

    4. Doors and Windows

      The rainwater is the source for water seepage through doors and windows. During rainy seasons, the rainwater enters the house through the gaps at the window and door joints. Some waterproofing materials are available in the market for sealing the gaps between the windows and doors to block the water from entering the house. Most commonly, silicone sealants and waterproof tapes are used for stopping the water infiltration through the gaps between the windows and door joints.

    5. Bathroom and kitchen

      Water usage is inevitable in both the kitchen and bathroom areas of the house. The bathrooms are exposed to water all over the day while the kitchen uses water only in the sink or the dishwashing area. The bathrooms need to be treated with waterproofing materials thoroughly to avoid water seepage to the other parts of the house. It is essential to block the water from the bathroom to get infiltrated into the building. One needs to place tiles on the walls of the bathroom to avoid infiltration of the backsplash water. The bathroom floor need to be treated by waterproofing materials and the joints are required to be sealed with silicone sealants and any other sealants to avoid water seepage.

      Waterproofing the kitchen space can be very easy comparatively. The areas under the sink and the pipelines got to be free from water leakage and sealed with waterproofing materials. Backsplashes are also used in kitchens as an oil and waterproofing solution when cooking.

    6. Overhead tank

      Most of the house owners prefer keeping their water tanks at the top of the house to enhance functionality and minimize the energy bills. Unlike the other structures if the house, the water tanks hold the water required for supplying to the entire house or the apartments. As the overhead tanks are present on the top of the building, it is easier for the water to infiltrate throughout the building. These reasons make it mandatory to waterproof the overhead tanks. When you skip waterproofing your overhead tank, the water infiltrates into the walls of the house and ruins the interior look as well as weakens the structural strength of the building.

      Similar to the overhead water tanks, it is also important to waterproof the sump tanks, swimming pools and other structures that hold water for a long period of time because these structures undergo more pressure and stress due to water than the other ones.

    Waterproofing treatment is one of the necessary treatments that every building needs to remain strong and last long. Hire a waterproofing contractor and waterproof your building too. You can hire one by just answering the form given above.

    Most commonly asked questions to a waterproofing

    What are the signs of water leakage in the building?

    Water seepage is very common among the 90% of the building owners in India. As concrete is porous by nature, it allows water to infiltrate into itself. The water leakage into the walls, basement, and ceiling are visible in many building, particularly during rainy seasons. Some of the signs of water leakage in the building are

    1. Evident water leakage from the ceiling, wall or the basement.

    4. Mold or mildew growth
    5. Water rings

    Why should I waterproof my house?

    Waterproofing can be beneficial to the house in many ways. Some of the benefits of waterproofing include its support in the enhancement of the structural strength of the building. Waterproofing helps in increasing the value of the house. Basement waterproofing protects the house from the risk of flooding. It promises a healthier space by stopping of the mold growth. It helps you avoid recurring electrical and wooden furniture repairs by blocking the way of moisture from getting into the house. It is essential to waterproof your house to get all these benefits and avoid the damages caused by water to your building.

    What are the major causes of water seepage in the building?

It can be from the leakage from a broken pipeline inside the walls, water infiltration from the overhead tank, and seepage due to an increase in the groundwater level. The other significant cause is due to the rainwater. As mentioned earlier, concrete is naturally porous allowing water to enter the building. In some cases, the cracks in the building allow the water to infiltrate into it.

    How can I protect my house from monsoon rains?

    Waterproof your house. One of the other main sources of water that causes water seepage is rainwater. Both the downpour and the stagnant rainwater contribute to water infiltration into the house. Waterproofing solutions are the best plan to protect the building from monsoon rain.
