Product description

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

Scope of Application
Installation Methods& Vedio
Classic Projects Reference

It is suitable for waterproofing projects for industrial and civil buildings, public buildings, garage roof, subway station rooms, comprehensive pipe corridors and other building roofing or underground space roof.

The installation of root puncture resistance waterproofing membrane is combined with advanced and mature technology , and complete application . Hot air welding is adopted for the overlaps of membranes, and between membrane and prefabricated accessories . The Installation are basically categorized as ballasted system and full adhered system 

 

Ballasted System 

The membrane is installed by adhesive or metal battens at certain area .The remaining area is not attached . Overlaps is welded by hot air. The wind uplifting force is withheld by the weight of ballasted materials . 

 

Fully -Adhered System 

The membrane is adhered to base with adhesive or using Otai self adhesive waterproofing membrane . Overlaps is welded by hot air .
