Concrete Expansion Joints

Concrete expansion joints are primarily utilised to compensate for expansion and shrinkage in concrete due to temperature changes and other factors.

After concrete is poured and moulded into shape it will harden and set which naturally causes a reduction in volume. Steel reinforcement (within the concrete itself), Granular fill, and adjoining structures can restrain the shrinkage and can lead to tensile stress within the concrete area. Tensile stress can cause the weakest area of the concrete material to crack and that is where expansion joints can assist.
