Make sure your concrete is totally watertight.

Sika Greenstreak Waterstops have been keeping water in or out of structures for decades. Concrete structures are only as watertight as the waterstops that join them. We offer the industry's most comprehensive line of waterstops available today.

PVC Waterstops

Sika Greenstreak PVC Waterstops are the benchmark for the industry. Sika also provides and stocks many factory fabricated intersections and directional changes.

Surface-applied Waterstops

Sika Dilatec is a surface applied waterstop for sealing movement joints, construction joints, and connections to waterproofing membranes.

Nonswelling Gasket Waterstops

Sika Lockstop is a single component, self-sealing mastic waterstop that prevents moisture from penetrating non-moving joints in concrete construction.

Tie Hole Seal

Sika X-Plug is the only mechanical plug for taper tie voids designed to seal the void formed in a concrete wall by the removal of a taper tie rod.
