LOGICBASE V-ST
Non-reinforced PVC membrane used as the second layer in double-layer PVC waterproofing systems with vacuum quality control
LOGICBASE V-ST is a special PVC membrane, which is used for waterproofing of tunnels, foundations, underground parts of buildings and structures as the second layer in double-layer PVC waterproofing systems with vacuum quality control. It is also used as a protective layer of the waterproofing PVC system. The material is welded with the hot air to the main waterproofing layer. Overlap seams are welded by hot air welding equipment.
LOGICBASE V-ST is a non-reinforced synthetic membrane produced by co-extrusion on a base of premium quality plasticized polyvinyl chloride (PVC-P).
A specially textured surface of the material prevents two membranes of a double-layer waterproofing system from sticking together during the vacuum quality control.
