  • Patent number: 6238766
    Abstract: A tough, high-strength geomembrane made from a custom blend of polyethylene copolymers, for protecting waterproofing courses from impact and pressure damage of debris resting against the waterproof course. A slip sheet configuration reduces surfaces stress due to earth movement and subsurface cracking thereby maintaining the protective course intact without any effect on the waterproofing layers. The geomembrane is available as lightweight rolls which can be easily be handled by one man. The film is installed horizontally in continuous sheets with few adhesive joints. Installation begins by applying a thick brush coat of the selected waterproofing membrane material (usually a rubber coat but may be any waterpoofing material). The film is unrolled along the wall, held up into position and secured using plastic self-sealing plugs and/or plastic termination bars. Concrete nails are used to attach the self-sealing plugs or termination bar to the wall.
