Waterproof Paint: This paint or coating can be purchased at most hardware stores and can be applied by the homeowner. However, many homeowners try to use concrete to patch the crack. Concrete expands and contracts naturally as moisture and temperature conditions fluctuate. This is the perfect place for water to enter the basement. Some of these wall panels can create a vapor barrier, resist mold growth, and can integrate with basement drainage systems. This coating is not intended to stop all moisture and will flat bar Manufacturers not bridge cracks that are caused by settling.
Seeping Moisture: Even when your basement is not leaking, moisture will pass through the porous concrete. Unfortunately this solution will not last more than a few months, or a few years, at best.
Waterproofing From The Exterior: Instead of coating the basement walls from the inside, some contractors will instead coat the foundation walls from the outside with a damproofing or waterproof coating. Basement walls can leak from cracks, around pipe penetrations, and from basement windows. As the wall continues to naturally contract and expand the concrete will crack, just like the wall.
