The ODE Granat GP 400 Viaduct Waterproofing Membrane is the long-lasting APP modified, plastomeric bitumen based waterproofing membrane coated on top with silica sand, used for waterproofing of viaduct, bridge, and railway decks. The carrier felt is positioned on top due to the rough nature of the underlying surface, thus ensuring that the lower section that will come into contact with the floor is thicker.
