To provide protection for your basement walls, we install , a non-permeable, waterproof polymer. The tough Rigid Sealer will never crack, chip or peel and easily bridges cracks and other defects in your basement walls. The visible side of the Sealer is made of attractive, stain-resistant sheeting that can be wiped clean with most household cleansers.
