Abstract: A high strength polyester strap, preferably polyethylene terephthalate, suitable for higher load applications that typically require steel strapping. The strap is made by a process in which an extruded strand or sheet of polyester is subjected to a plurality of stretching steps with a final stretch ratio of at least 5 to 1. Raising the temperature of the strap in at least one of the stretching steps is preferred. In a preferred embodiment, the strap is surface treated to reduce the brittleness of the strap and to improve weldability. The profile of the strap is flattened as part of the surface treatment which treatment enhances the weldability of the strap.

Abstract: The present invention provides a waterproofing membrane for use on inclined surfaces. The membrane is fabricated from one or more layers of flexible sheet material preferably consisting of woven or nonwoven synthetic polymers of polypropylene. The membrane has a top surface and a bottom surface, where the bottom surface is intended to face the inclined surface. A skid resistant pattern of polymer elements is applied to the top surface of the membrane. The polymer has a Tensile Modulus 50% (ASTM D638, 23C, 50 mm/min, and a Shore A Hardness (ASTM D2240, 23C, 0 sec) 50% (ASTM D638, 23C, 50 mm/min, and a Shore A Hardness (ASTM D2240, 23C, 0 sec)
