PVC and EVA waterproofing membrane widely used in underground tunnel projects. It is a new polymer waterproofing membrane, which is made of high quality flexible (plasticized) polyvinyl-chloride. It has advantage of good elasticity, high ductility, little contraction ratio, good flexibility under low temperature, anti-aging and long service life etc.
The following specifications are for the supply and installation of flexible plasticized PVC membrane waterproofing systems for use in underground construction to prevent the infiltration of water into the structure. The membrane is to be installed over a geo-textile layer which provides drainage and protects the membrane from substrate damage.

All seams are to be welded and tested to insure a watertight homogeneous seal of the membrane system. A final structural lining will then be placed against the membrane waterproofing system.
