Tips For Waterproofing Basement Walls Permanently

The basement is built at a low grade and it has a higher chance of storing water that may damage the entire interior walls with stored furniture. There are two options either to install a drainage system that requires a huge amount of money through a foundation contractor or to use a do-it-yourself remedy.

Both of the concepts are explained in detail so here are some tips on waterproofing basement walls and how to locate the leaks and fix them properly.

Determine the wall leakages

The concrete block walls are porous so it is easy to determine where the water is coming from. Some of the sources are window well leaks, pipes, cracks on the corner of the basement wall, etc. During the rainy season, the soil becomes saturated causing water seepage that penetrated into the basement through corners. In this case, it makes the wall moist, damp which results in the peeling of paint, mold growth and condenses the entire basement walls.

The best way to check the condensation is to, take a one-foot(12×12) piece of aluminum in a square and paste it over the wall using duct tape. Leave it for 24 hours then remove it, if you see water inside the foil on the wall then it requires a waterproofing product. If the water comes on the outside of the foil, it means the water evaporates inside and makes the basement humid-a high-performance dehumidifier is required in that case.

Always Check Window Well Corners

The most common impact causes dues to window well leaks these cracks allow the water to seep through the window and enter into the basement. It makes the walls moist and also creates a water pooling this sudden happens because when the house was built there is no proper drainage system installed in it.

Well, digging using gravel is not a good option under the wall so the next step is used to the caulk. These help in masonry by using GE silicone window and wood caulk that is covered by the slopy Shape Polycarbonate Universal Fit Window Well covers (Available on Amazon), which helps in diverting the rainwater away.

Use Of Hydraulic Cement On Basement Walls

Hydraulic Cement is a type of cement used to fill minor cracks and works as a heavy-duty material for basement walls. It contains additives chemicals when applied it expands becomes hardened concrete that creates a watertight bond on the walls.

These cracks fill in 3-5 mins and are important to fill because these are the weakest point of the basement walls.

Efflorescence or Apply Muriatic Acid On Walls (Do Not Use Sealer)

The white powder that forms on the surface of concrete walls that causes moisture is known as ” Efflorescence”. This process is done before applying the new paint or removing the older paint using a wire brush. After this process, it is easy to apply sealer using a DIY trick.

For removing this naturally occurring salt we use DRYLOK Etch (Available on Amazon)- a perfect Muriatic acid that helps in adhering to the masonry perfectly. After applying this or other sealers let it dry for one day then coat paint over it.

Coating With Masonry Waterproofing Product

Types/Forms of Basement Water proof Wall

The basement wall is divided into two criteria when we talk about installing a proper drainage system inside as well as outside.

There are two types of basement walls such as

  • Interior Water Proof Basement Wall
  • Exterior Water Proof Basement Wall

Interior Water Proof Basement Wall

The interior waterproof basement wall is also known as inside walls. When there is a high water table there is a need to install a drainage channel inside the basement floor. It is similar to the exterior waterproof basement wall but it fits below the ground by using membrane materials. These materials are covered by plastic materials that stop the water seeps into the basement.

This allows to hide the original dry walls and the water passes through the old walls directly into the machine, and a sump pump throws out the water onto the outside of the garden. However, the cost of installing these french drain pipes costs approximately $5,000 which is a huge amount as compared to the polyurethane materials.

Exterior Water Proof Basement Wall

The exterior waterproof basement wall is also known as the outside wall. When we check the cause of water wet basements it is always better to check leaking gutters, drainage solution if required, improper grading, and remove the foundation plantings, shrubs, bushes near the area.

After following the above steps next is to install a drain tile system. This process is known as excavation which means removing the soil from outside and putting a perforated drain at the below level. It is attached to the waterproof membrane with a machine discussed above that pumps water to the surface.

It cost you between $10,000-$30,000 and can only be done by a foundation contractor, but it would be the best fit solution for the basement water problems.
