AKWASWELL

A polyurethane-based caulk grade swelling paste, AKWASWELL is used primarily to seal rough surfaces in concrete construction joints. Swelling up to 500% of its initial volume when hydrated by water, it creates a positive seal and stops the flow of water through the joint and is suitable for low to moderate hydostatic pressure conditions.
