Basement Waterproofing Products and Systems
There are several products that can keep your basement dry and free from water damage or seepage, including acrylic and liquid floor coatings.
Acrylic coating can be used as a sealant for the interior of a basement or on the exterior of a home that has foundation walls that are above ground. The coating can easily be painted or sprayed onto block or stucco walls. Tuffcrete is one waterproofing product that is acrylic based.
Liquid rubber coating is easily painted onto basement surfaces and is ideal for waterproofing a home that is frequently exposed to flooding or wet conditions. Liquid rubber sealants, like "Rubberize It!," bond to most construction materials and can serve as not only a way to waterproof a basement, but repair a leaky roof or a crack in a garden fountain.
Another popular sealant is Drylok, a waterproofing product that works on several surfaces, including concrete blocks, stucco, brick and retaining walls. Drylok is applied to the walls of a basement similarly to how one would apply paint to the walls of a home. Just like paint, Drylock can have a strong odor, meaning there should be adequate ventilation when applying the product. A second coat may be required.
Companies like B-Dry also provide products to waterproof a basement. Their sealer panels cover cracks and defects in basement walls.
