Vandex Super penetrates concrete and reacts with free lime to form crystalline complexes that block surface capillaries and voids. Concrete becomes waterproof and chemical-resistant, but water vapor is still able to pass. Applications include waterproofing foundation walls, concrete slabs below ground level, elevator pits, parking garages, landscaped roof slabs, swimming pools, wastewater and drinking water structures, water filtration plants, hydroelectric plants, dams, and aquariums.
