WPM SW series

Swellable waterbar

DESCRIPTION

WPM SW is a swellable waterbar based on polymer technology and designed for use in construction joints. WPM SW slowly swells in volume when in contact with water and efficiently waterproofs the construction joint. The pressure of the swelling action will cause the WPM SW to profile itself exactly into the joint and effectively stopping water seepage, even at high external water pressure.

WPM SW is suitable for all construction joints subject to hydrostatic pressure, on one or both sides. Movements in the joint (eg., shrinkage or settlement in the substrate) are taken up by the elastic profile of the waterbar.

FEATURES

• Unrestrained volumetric expansion of 300%
• Flexible and swellable, can absorb construction movements
• Swelling properties unaffected by long term wet/dry cycling
• Suitable for all water qualities including saline water
• Expands slowly to ensure non-disturbance of fresh concrete
• Easy to install
