Cetco Waterproofing

Ultraseal is a technological advancement in below-grade waterproofing that combines natural sodium bentonite and a chemically resistant hydrophilic polymer to form a bentonite-polymer alloy (BPA). Ultraseal provides exceptional performance unmatched by other commercially available waterproofing systems. The key to Ultraseal?s exceptional performance is the unique bentonite-polymer interaction formed through a proprietary blending process. This process produces a homogeneous alloy with improved contaminant resistance, enhanced swelling properties, and a baseline permeability one magnitude better than natural sodium bentonite. Not only does Ultraseal have a lower permeability, it weighs 50% less than traditional bentonite products, making it easier to handle and install. The active, swelling properties of the bentonite-polymer alloy seals small concrete cracks and works under continuous and intermittent hydrostatic conditions.
