G-Flex by Guru is a polyethylene membrane with a raised circular pattern. The back of the membrane is covered by a geotextile fiber. Acts as a waterproofing membrane, compensates vapor pressure if moisture appear on the substrate and a uncoupling membrane on critical substrates. We leave the different uses of the membrane: Food plants, dairies, breweries, airports, kitchens…
G-Flex is an anti-fracture waterproof decoupling sheet that protects and improves durability of tile installations outdoors and indoors when installed on critical supports; fissured, with movement or with moisture vapor stress.
STRUCTURE: G-Flex is a 1/8″ (3 mm) thick multilayer system with nodular geometric structure. It is made up of a 0.5 mm thick high-density polyethylene (HDPE) waterproof sheet with 3/32” (2.5 mm) square cavities and a non-woven veil of thermo-bonded polypropylene fibers at the base of the cavities. Conforms to definition for uncoupling membranes in the Tile Council of North America Handbook for Ceramic Tile Installation. The method used to establish the overall performance of a tile assembly under loading is the ASTM C627 “Standard Test
Method for Evaluating Ceramic Floor Tile Installation Systems Using the Robinson Type Floor Tester.”
