Swellseal 3V is a tough, hydrophilic waterproofing strip made from a combination of an elastomer and a hydrophilic resin. Swellseal 3V can be used for sealing joints between concrete precast elements, horizontal and vertical construction joints, sealing pipe penetrations, sealing concrete to steel joints and tunnel segments.

Swellseal 3V requires a minimum of 100mm concrete cover on all sides.
