Flexible Expansion Jointing is used in all standard concrete constructions such as driveways, footpaths and floor slabs. The jointing assist in preventing cracks and breakages in slabs, which are often caused by the expansion and contraction of concrete due to changes in climatic conditions.  Concrete joining products work to allow controlled movement in concrete slab joints, to control and prevent the cracking within the concrete slab and to form contraction joints in concrete slabs.
