HYDROSTOP WSM is a gun-applied mastic sealant for application where a swellable mastic is required to provide an effective watertight seal in confined applications.
HYDROSTOP WSM is used as an adhesive for bonding HYDROSTOP BR to concrete substrate. It is also used as a hydrophilic sealant for providing an effective seal in difficult areas which preclude the use of the hydrophilic water stop. It is used for sealing around pre-cast segments, metal beams, service penetrations and as an effective mastic for the bonding of HYDROSTOP BR to HYDROBAR PVC WATERSTOPS.
HYDROSTOP WSM should not be used for expansion joints or joints where significant repetitive movement is expected. HYDROSTOP WSM should only be used where there is more than 75 mm concrete cover. HYDROSTOP WSM should not be used as a sealant in general building applications.
The hydrophilic properties of HYDROSTOP WSM display good consistency in swell rate during repeated wet/dry cycles. When it is confined by concrete it will create a positive pressure against the face of the concrete joint which will prevent the passage of water.
