I.What is PVC Root Resistant Waterproof Membrane?
PVC Root Resistant Waterproof 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 .
II. ADVANTAGES OF PVC Root Resistant Waterproof Membrane
Most commercial buildings have flat roofs. Although there are several types of roofing membranes, the three main varieties are EPDM, TPO and PVC. Of these three, PVC flat roofing membranes can have a lifespan of at least two decades. This is only one of their many benefits. Here’s what you need to know about PVC roofing.
PVC is a high quality, durable option for commercial roofs. PVC membrane is one of the most frequently used waterproofing products for roofs. It is both water and vapor permeable and can be reinforced to offer extra durability. It is also very easy to install and has a long lifespan.
SHELF LIFE
Do not store product exposed to weather and sun. When kept in a cool, dry and protect area, sealed pail have a 12-months shelf life.
III.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
