Firestone GeoGard Rubber Liners are a cured single-ply membrane made from an EPDM polymer formulated to be fish and plant friendly.
Preparation of Substrates:
1. Substrates must be clean, dry, smooth and free of sharp edges, fines, loose or foreign materials, oil, grease, and other materials that may damage the geomembrane.
2. All roughened surfaces that can damage the geomembrane shall be repaired as specified to offer a smooth substrate.
3. All substrate voids greater than 6.3 mm (0.25") wide shall be properly filled with an acceptable fill material.
Method of Application:
Firestone GeoGard Rubber Liners are to be installed in accordance with current Firestone Specialty Products specifications and details.
