PVC Root Resistant Waterproof Membrane(P)
Otai Polyvinyl Chloride (PVC) waterproofing membrane is a type of new high macro-molecular waterproofing membrane by adding plasticizer,filler ,anti-oxidizer,ultraviolet light absorber and other auxiliaries with polyvinyl chloride resins as raw material.
This product is specially certified by Beijing Institute of Landscape Science ,which has the characteristics for plant root puncture ,durability , anti-corrosion and anti-seepage .
Product Features
1. High tensile strength , good elongation , strong applicability for base expansion or cracking deformation .
2. Large width ,high construction efficiency , small product consumption .
3.Good diffusion of water vapor , easy discharge of condensate , easy discharge of moisture left in the substrate
4. maintain good flexibility even at -25℃
5.High Security without open flame installation
