PVC Membrane is a modern waterproof roofing material. This waterproofing membrane is made of high quality water resistant material called polyvinylchloride. PVC membrane are considered more flexible comparatively and have high tear resistance quality because of this traits this type of waterproofing membrane is used for the purpose of waterproofing of underground structures, tunnels and swimming pools.
PVC is purely waterproof membrane and friendly by nature it holds its original shape well and easy to install and wash. Before installation of PVC membrane a primer is coated on required area for complete and proper installation of PVC waterproofing membrane.
Polyvinyl-chloride (PVC) Waterproofing membrane
There are many types of waterproofing material available in the market the most commonly used waterproofing material include following:
- Cementitious coating
- EPDM rubber
- Rubberized Asphalt
- Bitumen membrane sheet
- PVC membrane sheet
PVC is a high quality modern roofing material with high flexibility commonly used in waterproofing of buildings. This material is quite easy to install and considered durable because of its long service. These qualities of this membrane keep it higher level as compared to bitumen membrane sheet. After installation of this membrane there is no need of constant maintenance and repair.The structure of This membrane make if strong and flexible which reduce the effect of precipitation and ultra-violet radiation. Its installation reduces the effect of heavy surface and tensile loads. Because of vapor permeability feature of this membrane there is no need of instant repair if some parts of membrane are damaged. This feature contributes to prevent and remove moisture from the building.
This waterproofing membrane installation can serve for more than 50 years without losing its all positive features which make it durable. This type of membrane is generally installed on flat roof and does not require additional maintenance during installation process on the surface.
Hot air welding machine and building dryers are used during PVC installation. Manual dryer is used at the places where the usage of machine is not possible. The surface which is covered by this membrane is called the sealed surface.
