TRENCHCOAT™ Protective Film can be laminated to corrugated steel pipe (CSP) to protect it from the corrosion and damage associated with chemically aggressive environments in water-conveyance and horizontal landfill methane-recovery applications. The film is laminated to the soil and effluent sides of CSP, spiral-ribbed or triple-ribbed pipes in a variety of diameters. In water-conveyance applications, two kinds of film are available – TRENCHCOAT Light Gauge Protective Film and TRENCHCOAT Heavy Gauge Protective Film. Both have unique properties and help meet needs in water-drainage and culvert application.
