Bentonite-based swelling paste for the installation of swelling tapes

BentoMastic 307 is a water-swelling sealant made from natural bentonite. It dries quickly and has good adhesion to the substrate.

BentoMastic 307 is used for the reliable sealing of construction joints in concrete, for sealing wall penetrations in areas in contact with the ground, for joint filling in precast elements, and for similar applications where the swelling effect of activated bentonite can prevent the ingress of water into the structure.
