De Neef Sweallseal®

SWELLSEAL® hydrophilic waterstops expand upon contact with water to fill a void or joint and create a compression seal waterstop. Unlike traditional molded waterstops that are a fixed sized and must be placed in fresh concrete, SWELLSEAL® hydrophilic waterstops can be placed in any joint or interface. Old to new concrete, concrete to steel joints, between precast concrete members, or even steel to steel interfaces are no problem for SWELLSEAL® hydrophilic waterstops. Available in extruded rubber shapes or as a gun grade paste, SWELLSEAL® hydrophilic waterstops offer effective solutions for difficult surface to surface sealing applications.
