Waterproofing Membranes are mainly used in building walls, roofs, tunnels, highways, landfills, and other places to resist external rainwater and groundwater leakage. They are a flexible building material product that can be rolled into rolls. As a non leakage connection between the engineering foundation and the building, they are the first barrier for waterproofing in the entire project and play a crucial role in the entire project.
Product features
1. Water resistance: Water resistance refers to the basic unchanged performance under the action of water and after being soaked by water, but has impermeability under the action of pressure water, commonly expressed by indicators such as impermeability and water absorption.
2. Temperature stability: Temperature stability refers to the ability to maintain its original performance under certain temperature changes, without flowing, foaming, or sliding at high temperatures, and without brittle cracking at low temperatures. Commonly used indicators such as heat resistance and heat resistance.
3. Mechanical strength, elongation, and fracture resistance: It refers to the performance of waterproof rolls that withstand certain loads, stresses, or do not break under certain deformation conditions. Commonly used indicators such as tensile strength, tensile strength, and elongation at break.
4. Flexibility: Flexibility refers to the ability to maintain flexibility under low temperature conditions. It is crucial to ensure easy construction and non brittle cracking. Commonly used indicators such as flexibility and low-temperature bending.
5. Atmospheric stability: Atmospheric stability refers to the ability to resist erosion under the long-term comprehensive effects of factors such as sunlight, heat, ozone, and other chemical erosion media. Commonly used indicators such as aging resistance and thermal aging retention rate.

1. High tensile strength, good elongation, and small thermal size change rate.
2. Resistance to aging, UV radiation, chemical corrosion, and root penetration.
3. Having good weldability, the seam is integrated with the substrate after hot air welding.
4. Has good water vapor diffusion, and condensate is easy to release.
5. Good low-temperature flexibility and adaptability to environmental temperature changes.
6. The light colored surface reflects ultraviolet radiation, and the surface of the coil absorbs less heat, resulting in low temperature.
7. Long service life (25 years on the roof and over 50 years underground), and no environmental pollution.
8. The detailed processing is very convenient, maintenance is simple, and the cost is low.
