Cracking and failed joints in concrete structures may result from a range of factors including settlement, thermal stresses, faulty workmanship, and day-to-day use of the facility, if any of these cracks or joints is water bearing it can start to attack the structure itself or limit and prevent the use of these areas of the structure.

Sika’s crack injection systems can be used to seal water bearing and dry creaks and joints or to provide a waterproof curtain behind the structural envelope to stop water leaking into the structure.

Sika injection system can also be used in new build projects to seal construction joints through inject hoses cast into the concrete joints.
