Step 1: Clean The Basement

Cleaning the basement is the first step in basement waterproofing. Dirt and impurities will undermine the efficiency of any waterproofing materials or products applied on the basement surface. To get maximum results, clean the basement thoroughly. Moreover, you must remove all the existing coatings on the surface of the basement because most waterproofing products only work effectively when applied directly to the substrate.

Remove old paint with a sandblaster or a wire brush. Ensure that the surface is properly cleaned. Wash the walls clean using dish soap, warm water, and a scrub brush. Add a cup of bleach to the solution to clean the mould in the basement. Meanwhile, check the composition of the dish soap and ensure that it does not contain ammonia before adding bleach to it. Rinse the walls and floor thoroughly with clean water.

Step 2: Plug Holes

Fill all small cracks with masonry crack filler. This will ensure that water cannot leak into the basement and compromise the entire basement waterproofing project later in future.
