Waterproofing membrane

Waterproof membrane is mainly used for building walls, roofing, such as tunnels, highways, landfill, to resist the outside water, ground-water seepage can be curled up into a roll of flexible building materials products, as a project basis and no leakage connection between buildings, is the first barrier of waterproof, plays a vital role on the whole project. Products include polymer waterproofing roll-roofing and waterproofing asphalt.

Bitumen or polymer waterproof materials impregnated in the fetal body, made of waterproof materials products, available in roll form, known as the waterproofing membrane. According to the main materials, is divided into asphalt waterproofing membrane, polymer synthesis of polymer modified asphalt waterproofing roll-roofing and waterproofing; depending on the carcass divided into no body roll, paper, tires roll, fiberglass tires roll, glass cloth tire coil and polyethylene coil.

Waterproof membrane requiring good resistance to water, temperature stability (no flowing at high temperature, do not rise bubble, not confusion; not brittle at low temperatures), a certain mechanical strength, extension and fracture resistance, to a certain degree of flexibility and resistance to aging, and so on.
