Waterproofing Of Reinforced Concrete Flat Roof
Product Information
PVC roofing membrane is a highly-engineered,new-type membrane manufactured
using polyvinyl chloride as main materials and added other chemicals such as anti-oxidant,anti-UV materials to make it flexible,stable and UV-resistant.
Product Features
- Long using life, aging resistance, the service life is more than 50 years for roofing and underground.
- High tearing strength, high extensibility and the size will have little change after heat treatment.
- Good flexibility at low temperatures and good puncture resistance.
- Easy for application and it is environmentally-friendly.
- Chemical resistance.
