Bentonite
Bentonite is a special type of clay material widely used in waterproofing services for buildings and construction projects. It's popular because it naturally swells when wet, creating a strong barrier against water. Think of it like a sponge that expands to block water from entering basements, foundations, and underground structures. This material is crucial for construction companies that focus on keeping buildings dry and protected from water damage. When you see this term in resumes, it usually indicates experience with waterproofing systems and foundation work.
