Crossgrip roof walkway system is an open grid, self draining, non-porous roof walkway matting system which is used on flat roofs to provide safe access for maintenance of roof top services. The system comprises two mats, Crossgrip PVC, manufactured from polyvinyl cloride, and Crossgrip TPO, manufactured from thermoplastic polyolefin. Impervious to all-weathers, Crossgrip is a slip-resistant, self-draining product that remains stable even in extreme, gusting winds. It will protect the existing roof covering whether traditional asphalt, 3-layer felt or, most importantly, a modern high performance single ply membrane. Crossgrip does not react with vinyl roofing membranes whilst offering continual protection to the roof's covering from pedestrian traffic. Furthermore, the TPO version is also compatible with TPO membranes.
