1.2MM Pre-Applied HDPE waterproof membrane for Basement Tunnel

详情

Product Description 

 

HDPE pre-applied waterproof membrane is made of three layers of materials，which are HDPE sheet, hot-melt pressure sensitive adhesive, and isolating material respectively. And the isolating material can be special sand(type S) and isolation membrane(type M)



Product Properties 



1.Pre-applied full-bonding installation: the HDPE pre-applied membrane sanding surface up temporary fixed on the bottom cushion. Direct binding reinforcement, and then poured concrete. The membrane coated sand layer will combine with it tightly ,no water moving between layers.



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 .



Classification:



S*-HDPE sheet with sand on the adhensive side.

M- with PE film on the adhensive side.

H:- Homogeneous HDPE sheet without any adhesive 



The scope of application



Underground waterproof projects such as subways, cave depots, tunnels, basements, bridges, water conservancy dykes, landfills, sewage treatment tanks and other municipal construction, etc.
