Concrete structures are only as watertight as the waterstops that join them. Structures such as water treatment plants, reservoirs, locks, dams, and below grade facilities, most likely have a waterstop system in place. Several factors must be considered when selecting a waterstop. They include, but are not limited to, joint type and joint movement, hydrostatic pressure and chemical exposure. Greenstreak offers the industry's most comprehensive line of waterstops available today. Please select from the materials below for additional information to consider when selecting the right waterstop for your project.

Mechanical Waterstops are embedded across and along the joint to create a diaphragm. Many profiles are suitable for moving joints: PVC and Stainless Steel.

Hydrophilic Waterstops are applied in and along the joint. Exposure to water induces expansion of the material to create a compression seal. Hydrophilic waterstops are suitable for non-moving joints only: Hydrotite, Swellstop, Duro-seal.

Mastic Waterstops are applied with a primer adhesive in and along the joint to create a self-sealing moisture barrier. Mastic waterstops are suitable for non-moving joints only: Lockstop.

Fuko Injection Waterstops provide a conduit for injecting joints with microfine cement or injection resins to ensure "zero leak tolerance". Injection hose waterstops are suitable for non moving joints only: FUKO
