TCSR-555 is two component solvent free epoxy system for repairing cracked and damaged concrete structures. It is used for bonding of new structural concrete to old concrete, bricks & steel component as it gives excellent bonding properties with various construction surfaces.
Excellent system for bonding of old to new concrete/mortar, repair old concrete structure and it can be extended further. It can be injected to seal damp & wet cracks more than 2mm by high-pressure injection and for better adhesion of concrete and steel.
