Swellable Waterstop
Description
PENTENS SW20 is a swellable water bar made of high quality hydrophilic material used to prevent water leakage from construction and expansion joints.
PENTENS SW20 can be installed and linked to conventional PENTENS PVC Waterstop networks. The swelling action is the result of contact between water and hydrophilic groups in PENTENS SW20. The hydrophilic group are not subject to extraction or loss of swelling ability through prolonged or repeated wetting. This is a unique feature of the basic polymer. Expansion of the waterstop creates a positives pressure against the face of the concrete joint, thus preventing water from passing through the protected joint.

Uses
- Integral sealing for construction joints cast in-situ where conventional waterstops are impractical because of limited access. A conventional waterstop would require complex shuttering.
Advantages
- Swelling properties are unaffected by long term wet and dry cycles.
- Tolerant to slat presence, concrete and groundwater.
- Easy installation by using adhesives or nails.
- Sustainable in wet condition.
- Solves detailing problems when used in conjunction with PVC Waterstop range.
Packaging
- 19mm x 25mm x 30m (roll)
