Description
PRODUCT DESCRIPTION
Hydrophilic Swellable Waterstop is a thermoplastic SEBS based construction cold joint water-stop. The profile has a Bond-enhancing grooved surface and unique swelling Properties with controlled and delayed expansion.
ADVANTAGES
- Active protection – hydrophilic water-stop swell in contact with water to form effective compression joints.
- It requires simple application and jointing techniques.
- It has a controlled delay expansion rate to prevent damage to freshly placed concrete during curing.
- It retains the original shape after repeated swelling and contraction.
- Swelling properties unaffected by long-term wet/dry cycling.
- It sustains an effective seal in wet conditions.
- Exceptional resistance to chemical attack.

SHELF LIFE & STORAGE
Hydrophilic Swellable Waterstop has an unlimited shelf life provided it is stored clear of ground in a dry and shaded place below 35ºC.
Design Criteria
Hydrophilic Swellable Waterstop should be used to prevent the passage of water through the non-movement joint in both new in-situ concrete and between new and existing concrete. The swelling of Vetostop SW1 in fresh concrete is minimal, and most of the volume swell takes place after the initial hardening of the concrete has taken place. Vetostop SW1 water-stop should be positioned to ensure that a minimum of 70 mm cover of concrete is present to accommodate pressure developed during the swelling process. It is recommended that the strip is fixed by both adhesive and mechanical means to ensure maximum contact with the joint faces and to avoid displacement when pouring the fresh concrete.
