As a result of thermal expansion, creep, shrinkage and traffic loading measurements of constructions can vary. To make this movement possible, several joints can be implemented. The dimensions of the joints vary. To create a flat joint at all times and prevent leakage, an expansion joint is applied. Examples where expansion joints are used are; bridges, viaducts, concrete road surfaces, airfield runways and the inner site of tunnels. The expansion joint can be used in old as well in new constructions.
