Product Introduction:

Waterstop strip is a special new type of waterproof product, not only does it have the performance of ordinary rubber products, but also its waterproofing property is better and more reliable than common rubber waterproof products. When it touches water, its volume will swell three or four times than the original volume and it will stuff up all irregular concrete joints, then achieve to stop leak thoroughly.

Product Details

The difference between PZ Type and BW Type

  • The performance of the PZ Type is better than BW Type.

  • PZ Type is vulcanized rubber, instead, the vulcanized process isn’t necessary for BW type.

  • Almost all BW type is back in the market, but PZ Type can be produced in a different color, such as black, red, blue, and so on (red and blue are more popular in the market).
