• Swellstop is a water-swellable, waterproofing sealant designed for use on many types of poured-in-place and below grade precast concrete applications.
• On exposure to water it will begin to swell to seal any exposed gaps in concrete joints. Swellstop has excellent adhesion to clean, dry concrete. It is specifically intended for non-moving joints. It features all weather application and is engineered for use under most temperature conditions.
• Swellstop stays flexible in cold weather without shrinking or hardening and does not require heating for application. In hot weather, Swellstop remains pliable and does not become spongy.

Common Applications:

• Foundation slabs or below-grade walls with cold joints,
• Prefabricated concrete wall panel systems,
• Septic tanks,
• Manholes for sanitary and storm sewers,
• Utility vaults, portable water tanks, and box culverts,
• Various pipes (round, oval, flat-base elliptical, and arch types),
• Wet wells.
