马鞍山塑料外贴式止水带 400*8
Plastic external water stop belt is a new type of water stop material, which is made of polymer resin as the main raw material and processed by special process. After welding with waterproof board, it forms the first waterproof line of concrete structure facing water surface, which is very important for prevention of leakage of concrete deformation joint. Post type waterstop used should be taken into account and lining concrete with fixed welding waterproof board, should use the same molecular structure and properties of waterproof board plastic waterstop in recent years, the domestic type of waterproof board is divided into several EVA, ECB, PE, HDPE and other materials, our company with various kinds of waterproof board as the carrier, in the original PVC plastic waterstop production base, and has successfully developed a series of polymer resin water stop, to meet the different needs of various projects, the construction is simple, the cost is moderate, is the ideal of a new waterproof material.
