Expansion joints must be provided in long elements and buildings to avoid cracks caused by temperature expansion or concrete contraction. The elements separated by the joint must, however, be supported to enable load transfer. Cantilevers or double walls are frequently planned on both sides of the joint for this purpose. But these solutions are very work-intensive and take up space.

This dowel connects the elements on each side of the joint without the need for additional constructions. In doing so, it transfers shear forces while sustaining the necessary mobility.
