PVC waterstop, also called PVC water stop seal or PVC waterstop belt, is manufactured from superior grade polyvinyl chloride resin and various chemical additives by the process of mixing, granulating and extrusion. It is used to prevent leakage and permeation in construction joint by taking full advantage of polyvinyl chloride resin property of good elastic deformation. It is highly resistant to corrosion and it has excellent durability. PVC waterstops are mainly used for tunnels, bridges, storage tanks, water and waste water treatment plants, dams, culverts and other places.
PVC waterstops can be manufactured in many shapes, such as dumbbell, base seal, flat ribbed, split dumbbell, dumbbell with center bulb, ribbed with center bulb, split ribbed and tear web. And we can manufacture PVC waterstop products according to customers' requirements, such as shapes and sizes. You can send samples to us, then we analyze samples, and we manufacture products according to samples.
