Sika Greenstreak Lockstop
Sika Greenstreak Lockstop is a strip-applied mastic waterstop for non-moving concrete joints. This 3/4 in by 1 in profile ships as a 100 ft carton of 16 ft 8 in rolls (part 419273) and bonds with Lockstop Primer adhesive. It does not swell, so it will not build internal joint pressure, and it installs in nearly all weather. Crews use it on retaining walls, culverts, penetrations, and vaults where a hydrophilic strip would over-expand.
