Bentonite Waterproofing | What are the problems with bentonite ...

Bentonite waterproofing is an exterior waterproofing treatment that is supposed to work by forming a barrier between wet soil and the building foundation. Like any type of clay, bentonite absorbs moisture. As water molecules bond to clay particles, the clay expands, filling cracks and gaps in the foundation so that water can't get in.
