How Does Bentonite Waterproofing Work?
The secret behind bentonite waterproofing lies in the natural properties of bentonite clay. When water touches this clay, it expands up to fifteen times its original volume, forming a gel-like seal that blocks water from seeping through cracks, joints, or porous concrete. This swelling action makes it ideal for below-grade structures where hydrostatic pressure from surrounding soil pushes moisture toward the foundation walls. Unlike traditional membrane systems that can tear or degrade over time, bentonite self-heals small punctures or gaps automatically. This makes it a long-term, maintenance-free solution for controlling groundwater infiltration and protecting your property’s foundation from water damage.
