SikaSwell S-2 is a 1-part polyurethane hydrophilic sealant which swells in contact with water to seal all types of construction joints and penetrations in concrete structures. It is used to adhere the SikaSwell A and SikaSwell P profiles to the structure. Suitable for use in hot and tropical climatic conditions.
SikaSwell S-2 is a specially formulated, high-performance, swellable, one-component, polyurethane-based waterstop for use in all kinds of construction joints. Swelling rubber creates a compression seal within joint, blocking the passage of water.
Designed for construction joints in new watertight concrete structures. Excellent for sealing pipe penetrations through walls and floor slabs. Excellent for sealing joints between precast elements. May be applied to horizontal, vertical and overhead surfaces. Ideal for watertight construction joints between new and existing concrete.
