Firestone GeoGard™ EPDM, is a single-ply synthetic rubber waterproofing membrane that is fish and plant-friendly. It is composed of ethylene – propylene – diene terpolymer, mixed with carbon black, curing agents and processing aids.

Firestone Geomembranes offer the following benefits:

Superior weathering resistance: Firestone GeoGard EPDM membranes offer unmatched resistance to ultraviolet radiation and ozone.

Year-Round Installation: Firestone GeoGard EPDM membranes stay flexible down to –45 °C – even after several decades of exposure, meaning year-round installation is possible in our harsh Canadian winters.

High elasticity: Firestone membranes can elongate over 300%, which means the membrane can stretch and conform to objects in the substrate, and will stay flexible during ground movements.

Quick installation: The membranes are available in large seamless panel sizes up to 15m wide and 61m high, meaning fewer seam seals are needed and the membrane is less susceptible to extreme weather conditions. The large panels size also reduces installation time.

Low maintenance: Firestone GeoGard EPDM membranes require little or no regular maintenance after installation. The geomembrane can survive normal Canadian environmental exposure for well over 30 years.

Environmentally friendly: Made of an inert material with low environmental impact during production and use, Firestone’s EPDM manufacturing facilities have received ISO 14001 certification.
