To make any houses/buildings more durable, it is very important to have a strong base and that is the main reason for basement waterproofing.

“Water your roots, so your soul can blossom’’

Similarly, waterproofing of the basement is very important for all of us because leakage in the basement plays a major role in its’ damaging or you can say, making your home less durable, especially in monsoon. This could be in the form of rain, leaking pipes, overflowing bathrooms, groundwater, etc.

Basement waterproofing involves techniques and materials used to prevent water from penetrating the basement of a building. Waterproofing of basement which is below ground level, requires application of sealant materials, installation of drains and sump pumps, and many more.

One of the worst mistakes you can ever make when it comes to basement waterproofing is to ignore the need for waterproofing in the first place. However, this is probably one of the most common mistakes homeowners make.

We Indians believe in ignoring the things until we can. So do not try to avoid such type of leakages in your home/basement otherwise it may cause many serious issues.  Don’t let rain turn your dream home into a damp space.

Consequences of not waterproofing a basement:-

  • Damage to basement interiors.

  • Reducing the lifespan of the building.

  • Weakening of the basement due to leakage may cause collapsing of the entire building.

  • Repairing cost will be double.

  • Flooding in the basement area.

  • Basement gets unhygienic

  • May cause serious health issues like dengue, malaria etc..


There are three major types of basement waterproofing solutions:-

  1. Interior Waterproofing – Applying sealants to any problem area where cracks allow water to seep in. Interior sealants will keep the humidity low in the basement, thereby avoiding condensation which helps to stop moisture. Sealants have increased durability as it binds with the basement walls and chemically reacts with the concrete to produce a waterproof barrier.

    If you have painted walls, you will have to use then waterproofing paint instead as the other sealants may not stick properly. Make sure to use a brush or roller to apply thick coats that can fill up cracks in all instances.

  2. Exterior Waterproofing –  Exterior waterproofing is generally more preferable and popular. In this method, you need to excavate the soil around your building foundation several feet deep. 

    Once this process is complete, the outside surface of your basement wall is thus coated with waterproofing membranes. It will block the possibility of serious groundwater leakage as well as water-based structural damage to the basement.


3.Water drainage –  It seeks to move water out of the ground, surrounding the basement and away from the home instead of simply blocking it. This type of waterproofing is preferred for buildings having raised foundation.

A bunch of porous plastic pipes is placed on the floor along the wall of the basement. They collect water from the concrete walls. The water collected leaves the pipes without using a pump as the foundation of the home is raised above the surrounding area. Such an arrangement relies on the pull of gravity to allow the water to move downhill away from the house.

The water drainage system can be done within two days. The cost may lie in between interior and exterior waterproofing.

Benefits of basement waterproofing:-

  1.  Gives strength to the building:- Waterproofing elongates the total lifespan of a building by reducing the possibilities of penetration of water and moisture.
  2. Healthy Environment:- Waterproofing is not just to ensure your building strength, but also to keep away health issues. Good waterproofing systems will help to create living areas and workplaces clean and hygienic.
  3. Brings down maintenance cost:- Proper Waterproofing reduces the overall maintenance cost by protecting the electrical works, paints, plaster, and interior designs to get effected from water.
  4. Clear and Fresh environment:- With proper waterproofing, you can enjoy a very clear and fresh living environment and workspace. It will keep your property safe, healthy, and clean.
