Foam fills cracks,gaps and holes

Sika Corp. has introduced Sika Boom, a onecomponent expanding polyurethane foam formulated specifically for concrete and masonry applications. This multi-purpose foam is used to seal, fill, bond, insulate, and deaden sound in cracks, gaps and holes that are too large for a conventional sealant. It is available in 12 oz. and 20 oz. can sizes and is designed for easy dispensing through a straw adapter that is included with each can. When applied, Sika boom expands two to three times its original size and will bond to most construction materials, especially concrete and masonry. For more information, visit
