VERDISEAL Waterproofing System
Tough spray-applied polyurethane forms a monolithic barrier across the roof deck, side walls, and any sloping surfaces in between, offering protection against water and root penetration for green roof projects.
The polyurethane layer eliminates the need for a root-resistant protective layer even in projects with invasive root species like bamboo. Root penetration through the membrane is a common cause of tears and leaks in green roof installations and can require expensive repair or replacement.
VERDISEAL requires no bitumen, open flames, or solvents for installation. It carries a 30-year warranty when applied by Dow-certified installers.
