Swellable Waterstop

Swellable Waterstop: Waterstops which are hydrophilic in nature, tend to swell when made in contact with water. This expansion takes place only on those parts subjected to water and hence gives it a very valuable application.

Figure 1:- The active hydrophilic ingredient is compounded into the TPE at the time of manufacture.
 

Figure 2:- Upon contact with water the swellable waterstop will expand uniformly, at a controlled                       rate and percentage.
 

Figure 3:- When there is no longer water present the waterstop shrinks back to its original size.

Applications of Swellable Waterstop

 

Whenever there is a leakage in the system, the swellable waterstop will expand in the direction of the leak and fill up the spaces and prevent water damage to the system by blocking the source of the leak.
