Quick Overview

SikaSwell A reacts with water in a controlled and reversible manner to provide and maintain a seal against water intrusion and hydrostatic pressure. As swelling pressure rises, SikaSwell A forms an exact seal with the surrounding surfaces and prevents water intrusion. A joint width up to 5mm can be sealed with SikaSwell A against head pressure up to 150 ft. STUVA testing of suitability is available upon request.
