What is bentonite?

Bentonite is primarily known as an extremely fine textured clay that is suspended in water. This natural clay possesses unique properties, such as high absorbency and swelling capacity when mixed with water, which can be beneficial for various applications, including roofing. In the context of roofing, bentonite can be utilized as part of a waterproofing layer to prevent water infiltration, acting as a reliable barrier due to its ability to expand and fill gaps when wet. Its composition and characteristics make it particularly suitable for applications that require effective moisture management.

Understanding the role of bentonite in roofing and construction helps illustrate its function beyond merely being a clay; it's an essential component in enhancing the durability and performance of built-up roofing systems.
