JORDAHL punching shear reinforcements transfer high shear forces from heavily stressed areas into the structural element to provide the best possible protection against punching shear failure. The products consist of double-headed anchors that are connected to each other by a strip. In this way, high supporting forces in flat slabs or foundations can be transferred with only a little formwork and reinforcement work required. Depending on the respective static requirements, the reinforcement is available in various designs or can be custom-made.
