AQUAFIN WATERSTOP
DOWNLOAD TECHNICAL DATA SHEET

AQUAFIN Waterstop is a strip applied hydrophilic rubber swelling waterstop for use in all kinds of cast-in-place concrete construction joints, as well as steel, concrete and thick-walled PVC (minimum 1/8”) pipe penetrations. When exposed to water, the rubber expands, creating a compression seal within the joint or pipe penetration, blocking the passage of water.
