SikaSwell® S-2

SikaSwell® S-2 is a specially formulated, high-performance, swellable, one-component, polyurethane-based waterstop for use in all kinds of construction joints. Advantage: Swelling rubber creates a compression seal within the joint, blocking the passage of water. It is specifically designed for construction joints in new watertight concrete structures, sealing pipe penetrations through walls, floor slabs, and precast elements. In addition, it can be applied to horizontal, vertical or overhead surfaces without any problem.

SikaSwell® S-2 is packaged in 600 milliliters sausage with a shelf life of up to 12 months from the date of production in undamaged, original packaging. It is advised to store the product in cool and dry space protected from direct sunlight and moisture.

Prior to its application, all surfaces must be clean, sound, free of loose particles, oils, and other contaminants. The surface may be dry or damp, with no presence of standing water on the surface. For optimum application, store at 70°F for a minimum of 8 hours prior to use; if the material appears stiff, knead the sausage for a short time before placing in a caulk gun.

SikaSwell® S-2 is applicable via the use of a caulking gun. Cut the nozzle to obtain a triangular extrusion section with a size fulfilling effective needs. Apply a uniform, continuous bead to the hardened concrete surface. Wait for approximately 2 hours after the placement of SikaSwell® S-2 before placing concrete. The minimum thickness of concrete around the SikaSwell S-2 should be 4 inches on each side (reinforced concrete) or 6 in. on each side (non-reinforced concrete) and 4 inches on top.
