Expensive and extensive. Installing a bentonite waterproofing system on an existing house usually calls for complete excavation of the foundation. Interior drain and sump pump systems are more affordable and also more effective.
Installing an exterior waterproofing system is one option for waterproofing a basement. Also referred to as “positive-side waterproofing,” this technique relies on a waterproof membrane or a waterproof coating to prevent water from entering the basement. The membrane treatment utilizes plastic sheet material and/or a thin layer of “Bentonite” clay that forms a water barrier. In terms of coatings for basement waterproofing, most exterior treatments have a thick, tar-like consistency and can be applied by brush or spray.
The best time to install an exterior waterproofing system is when a house is under construction. Installing this type of system on an existing house poses a number of problems, as explained below.
Is there an alternative to exterior waterproofing systems that will keep a basement dry? You bet. The WaterGuard® interior French drain system effectively captures water that leaks through basement walls and through the wall-floor joint. Nearly invisible when installed, this drainage system is warrantied to handle even the most severe basement water conditions, working with a sump pump system that pumps collected water to the exterior.
