Compound mat is made of two layers, the top layer is fiberglass mesh, the bottom layer is cotton mat. It is a kind of reinforcement combination material.
It is often used as the base mat of Modified SBS/APP bitumen waterproof membrane, which often used in the underground, building roofing, ground and pond, etc.
It is characterized as high tensile strength, easy soakage by bitumen, low cost and so on.
