Sika Greenstreak Waterstop Systems

Sika Greenstreak PVC, Sealant, and Strip Applied Waterstops

Offering a variety of solutions across all categories of waterstops, Sika has the knowledge and time tested products to meet the most demanding applications.

Sika Hydrotite is a world renowned hydrophilic waterstop. Composed of modified chloroprene rubber protected with a special delay coating, Hydrotite expands when exposed to water, creating an effective compression seal within joints where limited movement will occur. Hydrotite is used extensively in sealing concrete construction joints, pipe penetrations, precast concrete segments, tunnel lining segments and for repair of existing joints or retrofit applications.

Sika Swellstop is a flexible butyl rubber and swellable clay waterproofing compound that expands upon contact with water to form a compression seal in nonmoving concrete joints. Swellstop is available in two sizes and must be used in conjunction with Swellstop Primer Adhesive to create a watertight bond.

Sika Lockstop is a single component and self-sealing mastic waterstop which bonds to concrete to prevent moisture from penetrating nonmoving joints. Lockstop must be used in conjunction with Lockstop Primer Adhesive to create a watertight bond.

PVC Waterstop is the industry standard for flexible waterstops, which are typically embedded across and along the joint. PVC is the most versatile waterstop material, offering the broadest design selection and is accepted under the ACI 350 "Code Requirements for Environmental Engineering Concrete Structures". It has great inherent elasticity and is resistant to many waterborne chemicals.

Embedded in concrete, across and/or along the joint, waterstops form a watertight diaphragm that prevents the passage of liquid through the joint. Sika Greenstreak Waterstops are precision engineered for vertical and horizontal expansion joints between cast-in-place concrete units where conditions may subject the concrete to hydro-static pressure or moisture seepage. They are manufactured with the highest quality PVC to provide the strongest tensile strength and elongation capabilities possible with a superior resistance to alkalis, acids, ozone and waterborne chemicals. Sika’s complete line of shapes and sizes assures a long, lasting, watertight seal for every above or below grade concrete structure. They do not discolor concrete, nor do they produce or support electrolytic action with metal structures nearby or with embedded rebar steel. Sika Greenstreak Waterstops maintain their integrity indefinitely. They are the premium choice for strength, impermeability and elongation.

Sika Greenstreak, one of the first manufacturers of polyvinyl chloride (PVC) waterstop, has formulated, compounded and manufactured PVC waterstop for years. Sika has the knowledge, experience and desire to provide the highest quality joint sealing solutions and services available.

Sika offers the industry's widest array of PVC waterstop designs, typically ranging in widths from 4 to 12 in (100 to 300 mm) and thicknesses from 1/8 to 1/2 in (3 to 12 mm). Depending on size, most waterstop shapes are provided in 50 or 100 ft (15 or 30 m) coils.
