Black EVA waterstop.
EVA waterstop is a kind of new type waterstop. It is made of polyvinyl chloride, EVA resin and a variety of additives by special production processes. High quality materials make it have many functions and advantages. EVA waterstop with high elasticity and high tensile strength is not easy to be damaged by stretching. EVA waterstop has excellent corrosion resistance. So it is not corroded in the underground constructions or waste water treatment facilities. EVA waterstop is widely used in the structural joint of the building foundation to to prevent leakage and prevent seepage. And our products are in line with international standard. You can use it without any worries.
