Waterproofing
Polyurethane SystemsReservoirs, Water Tanks & Channels Waterproofing
Certified liquid-applied waterproofing for potable and process water containment.
Overview
A polyurethane liquid membrane engineered for water tanks, channels, and artificial ponds under constant hydrostatic pressure. Certified for use in drinking water tanks, the system protects simple to highly complex containment structures with a seamless, crack-bridging membrane that remains permanently flexible. High solar reflectivity contributes to thermal insulation of the contained water.
