Product Features
1.When casting concrete, the concrete mortar and material are combined to form a special macro molecular polymer to make curing reaction adhering, so that coiled material structure is adhered together permanently. No water fleeing inside the structure, and increase the reliability of waterproof layer
2.It has strong self-healing ability and can repair slight construction injury.
3.High strength of elongation, strong breaking tensile strength and good anti-perforation performance .
4..With strong chemical resistance to acid and alkali
5.Integration of self adhesion, waterproof and protection, so that can reduce construction links
6.Wet method construction, no need flat layer, low requirement for the base, not affected by weather and base moisture, it has obvious advantage of constructions in rainy season.
7.The floor board of the building should be constructed with a pre-applied anti-sticking method. This method no need protective layer.
8. one layer can reach level one waterproofing security requirements .

SCOPE OF APPLICATION
Waterproof and anti-seepage , caverns , tunnels , subway , bridge , water conservancy , dam , basement , landfill , sewage treatment pool ,municipal construction
Attentions
1.The Installation environment should be above 4 degree ,
2.The waterproof membrane can be directly laid on the “ not completely cured concrete” or wet base surface , but the base face should level off without clear water .
3.It is forbidden to enter the construction site wearing spikes
4.Pay attention to the protection of the site and prevent the wind from blowing.
