Swellable Waterstop
High performance swellable waterstops for in-situ concrete
Swellable Waterstop are suitable for use in contact with potable water. The SW20 is a swellable waterstop which can be installed and positively linked into conventional PVC waterstop networks. SW20 is used Integral sealing for construction joints in concrete cast in-situ. The swellable property will give pressure inside the joint. It is used where conventional waterstops such as PVC or Rubber waterstop are impractical to use because of limited access.
Advantages:
Solves detailing problems in conjunction with Cemstop PVC range
Easy to install by bonding, nailing or casting into joint faces
Swelling properties unaffected by long term wet/dry cycling
Sustains effective seal in wet conditions
The hydrophilic groups are not subject to extraction or loss of swelling performance by prolonged or repeated wetting.
Expansion of the waterstop creates a positive pressure against the face of the concrete joint, thus preventing water passing through the protected joint.
Size : 10mm X 20mm x 9m roll
