STEBBINS’ COLDSEAL is a 2‐component epoxy-based product that is used to form a seal around inserts or to repair cracks in concrete structures. The product can be placed using a pump. COLDSEAL is very successful when the void to be filled is large as it produces very low exotherm and shrinkage. Other products provide good chemical resistance but produce an unacceptable amount of heat when the components react together as they cure and can lead to cracking.
