Waterproofing materials made by impregnating asphalt or polymer waterproofing materials on the carcass are provided in the form of rolls, which are called waterproofing membranes.
According to the main components, they are divided into asphalt waterproofing membranes, polymer modified asphalt waterproofing membranes and synthetic polymer waterproofing membranes; according to the carcass, they are divided into carcass-free membranes, paper carcass membranes, glass fiber carcass membranes, glass cloth carcass membranes and polyethylene carcass membranes.
Waterproofing membranes are required to have good water resistance, stability to temperature changes (no flow, no bubbling, no turbulence at high temperatures; no brittle cracking at low temperatures), certain mechanical strength, elongation and fracture resistance, certain flexibility and aging resistance, etc.
Waterproofing membranes are a kind of rollable sheet waterproofing material. It is one of the important varieties of waterproofing materials for construction projects.
According to its main waterproofing components, it can be divided into three categories: asphalt waterproofing materials, polymer modified waterproofing membranes and synthetic polymer waterproofing membranes (SBC120 polyethylene polypropylene composite membranes). There are many kinds of waterproof membranes such as PVC, EVA, PE, ECB, etc. Asphalt waterproof membrane is a rollable sheet waterproof material made by dipping asphalt on the base (such as base paper, fiber fabric) and then sprinkling powdered or flaky isolation material on the surface.
