TamSeal CWS/ TamSeal PVC

TamSeal CWS is designed to combine the latest developments in hydrophilic technology with the traditional benefits of PVC waterstop. TamSeal CWS has been specifically designed to seal construction joints against the ingress or egress of liquids in water retaining or excluding structures. This new system enables the PVC waterstop to be fixed on site in the usual way and provides the additional benefit of exposing two hydrophilic elements before the pouring of concrete, thus avoiding the common problem of hydrophilic pre-mature swelling on site. TamSeal CWS is suitable for use in contact with potable water and can be used in situations where salt water and sewage are prevalent.
