With pre-stressed S&P CFK-Laminates, as well as concrete bearers, the dilation joints of the parking deck on the third basement level (-3) are coupled using frictional force-transfering connections. To achieve this, max. 2 x 4 laminates are applied onto the upper deck surface, to the left and right of the columns. The low-modulus laminates (E-Modul 170 kN/mm2) are pre-stressed to ca. 14 tons or 6 per mil (‰) using a press, and simultaneously stuck on to the deck using the epoxy-mortar S&P Resin 220. The small installation thickness of the pre-stressed laminates enable its application in the 4cm thick top concrete layer.
