How Waterproofing Is Done?

The process of waterproofing uses different procedures to avoid water from entering your home and commercial property. This is a vital measure which needs to be taken especially in places where there is a tendency of the water table rising, which in turn results in water seeping from cracks present in the wall. Waterproofing is a crucial task before the rainy season begins.

The Process of Waterproofing

Accumulation of water, especially in the basements, is a common household problem that can, fortunately, be quickly dealt with a few simple steps:

Preparation work

This is technically not part of the actual waterproofing process, but it is nevertheless an important aspect. This involves inspecting the area to find out what the cause of the problem is (i.e. cracks, a pipe connected to the outside, etc.). You will have to get the water out. This stage also involves making sure that the required tools are available.


The first step is ensuring their no water present in the house. This is done with the help of a pump. To ease the task, you need to install a sump pump in the sump pit. The foundation of your house also needs to be tested properly to see if the ground water is seeping in through cracks on gaps in the foundation joints. You can take the help of a professional for the task. Proper channels or drain systems need to be installed to remove water and prevent it from being soaked by the foundation footing.


Cracks in the walls are usually the primary causes. Water easily leak and seeps through these cracks and while they may not cause damage to your house right away, not doing anything about those cracks would cause a lot of problems in the future. This is why wall and foundation repair is necessary. Cracks can be sealed using a thin hollow rod to apply polyurethane sealants. Some sealants turn into a thick, waterproof foam when a fine mist of water is sprayed. Some experts use sodium silicate sealers that are applied by using a brush, a garden sprayer, or a roller.

Finishing the waterproofing

The thing is, waterproofing is not just about sealing cracks. Your basement, walls, and roofs were probably constructed using concrete, and that material is naturally porous. This means that water can easily get in even when the cracks have been dealt with. Waterproofing experts would apply waterproof paint to take care of that issue. There are even cases when the installation of an interior membrane is required for an additional layer of protection.

Double-checking for inside-outside connections.

Water can also penetrate via an opening that has been overlooked, so every tube, pipe, and conduit should be checked to make sure that there isn’t anything that would allow a significant amount of water in. You should also give importance to the drainage system to make sure that there is no possibility of water clogging and further damage to the house.

Water damage restoration

Of course, replacing all the water damaged goods would be up to the homeowner, but waterproofing experts can take care of drying, cleaning and even disinfecting the surface to make the area live-able.

Mold lookout

Many waterproofing specialists are also mold removal professionals. Still, you will need to be on your guard against water damage and mold, especially since those organisms can cause harm to your family’s health.

Restore and Protect

The final part is taking preventive measures from the water entering the house again. This includes taking steps for the interior as well as the exterior of the home.

After cleaning and drying completely, interiors of the house and the foundation need to be coated well using parging. This prevents damping of walls and the interior. To this layer, you can add another waterproof coating using waterproof paints. You can also add a concrete support at the foundation footing. This helps protect the most susceptible part, which is the foundation, against damping. You can also put new tiles on the floor or simply pack all the gaps of the floor to avoid water seepage from the ground.

Waterproofing is not a one-time thing. Cracks may appear again, and you may need to reapply waterproof paint after a while. But that’s a small price to pay for keeping water damage at bay – and for ensuring you family’s safety.
