When it touch with water, its volume will swell three or four times than original volume and it will stuff up all irregular concrete joint, then achieve to stop leak thoroughly.
Classification
It can be divided into BW type and PZ Type. Any client can select it according to different demand of water-proof construction. It is like below picture, the red one is PZ type, the other black one is BW type
Difference in PZ Type and BW Type
The performance of PZ Type is better than BW Type
PZ Type is vulcanized rubber, instead, vulcanized process isn’t necessary for BW type
Almost all BW type is back in market, but PZ Type can be produced in different color, such as black, red, blue and so on (red and blue are more popular in market)
