Steps to Effectively Waterproof Basement Walls

Most homeowners know that a leaky basement can be a serious problem that can often require a professional’s expertise. Water can damage possessions and create a health hazard, but it can also lead to structural problems with a home.

Waterproofing your  basement walls is one of the best ways to prevent leaks (and callbacks). While there are many methods that can be used, one popular method is to apply a waterproof coating to the walls, which will create a barrier that prevents water from seeping in. 

1. Remove All Standing Water and Verify That the Area is Completely Dry

It’s critical to remove all standing water before beginning any waterproofing job. After the area is completely dry, you may now begin to analyze the damage and select the most effective action. Any water left standing may hide a leak coming from the floor – not the wall – and will require a different solution to fix the problem.

 

2. Clean and Prepare the Area

Clean, dry and grease-free surfaces produce the best results. When removing dust, grime and any loose or broken masonry with a wire brush, it’s important to make sure that it’s completely gone. 

 

3. Plug Holes and Cracks

Once the area is clean and dry, you can begin plugging any holes or cracks in the walls with hydraulic cement. This will prevent water from entering the basement. 

 

4. Reseal Windows, Doors and Window Wells with Caulk

With a waterproofing project, it’s always a good idea to do an overall perimeter check on the home. Window wells are a common entry point for water, which makes it important to seal them properly. You can use silicone caulk or expanding foam. Windows and doors should also be sealed with caulking in order to prevent water from entering. 

 

5. Apply Waterproof Coating

Once the basement is completely dry, all the holes are plugged and the windows and doors are caulked, it’s time to paint the walls with a waterproof sealer.
