Sika Greenstreak Swellstop 1" x 3/4" 100ft Carton 419271

Sika Greenstreak 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.

Uses
Precast concrete wall panel systems
Septic tanks
Sanitary and storm sewer manholes
Utility vaults, portable water tanks and box culverts
Pipes (round, oval, flat-base elliptical and arch types)
Wet wells

Please note that Swellstop is not an expansion joint material and should not be used as one. Swellstop requires no special handling equipment. It is clean to the touch and does not contain any material that can discolor or irritate the skin.  

Sika Swellstop’s structural integrity conforms well to the underlying substrate and exhibits selfhealing properties when needed. Unlike many traditional clay-based products, Sika Swellstop will not expand to a point at which the waterstop itself is destroyed. Field experience has proven that products, which continually expand, lose much of their structural integrity and can actually erode when subjected to a constant flow of water. Furthermore, the controlled expansion properties engineered into Sika Swellstop, reduce the internal pressures created in cast-in-place applications, which can cause spalling in foundations and wall structures.
