SikaSwell A-2010 is an acrylic hydrophilic waterstop profile designed to seal construction joints and penetrations in reinforced concrete structures. The profile expands when exposed to water, swelling to fill gaps and prevent water ingress through joints and service penetrations.

The 20×10mm rectangular profile is commonly installed along construction joints prior to the second concrete pour. When moisture reaches the joint, the acrylic polymer expands to create sealing pressure inside the joint, helping maintain long-term watertightness in basements, retaining walls, water tanks and other underground structures.

SikaSwell A-2010 is typically bonded to the substrate using SikaSwell S-2 sealant before concrete placement.
