Corresponding parameter set not found, please add it in property template of background

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 .
