Application And Classification Of Waterproof Membrane

LW Brand Waterproof materials 







Asphalt waterproofing membrane is in the base tire (such as base paper, fibrous fabric) dip on asphalt, and then spread in the surface of powder or sheet of the isolation material made of curled sheet waterproof material.


1. Water resistance

Water resistance refers to the role of water and water infiltration after its performance is basically the same, under the action of pressure water is impermeable, commonly used impermeability, water absorption and other indicators.

2. Temperature stability

Temperature stability refers to the high temperature does not flow, no blistering, no sliding, low temperature does not brittle performance, that is, under certain temperature changes to maintain the original performance. Commonly used heat resistance, heat resistance and other indicators that.

3. Mechanical strength, extensibility and resistance to fracture

It refers to the waterproof membrane to withstand a certain load, stress or deformation under certain conditions do not break the performance. Commonly used tension, tensile strength and elongation at break and other indicators that.

4. Flexibility

Flexibility refers to the ability to maintain flexibility at low temperatures. It is easy to ensure that the construction, not brittle is very important. Commonly used flexibility, low temperature bending and other indicators that.

5. Atmospheric stability

Atmospheric stability refers to the ability to resist erosion under long-term effects of factors such as sunlight, heat, ozone and other chemical attack media. Commonly used anti-aging, thermal aging retention rate and other indicators that.
