RECOSTAL® Keyboard XLV/XLW
RECOSTAL® Keyboard XLV/XLW units are designed for the installation of isolation joints in industrial floor slabs and deck slabs with controlled cracks along the joint. The trapezoidal profile induces a key-profiled control joint. The top of the units consists of edge protection profiles which protect the concrete edges from spalling. There is a choice between type RECOSTAL® Keyboard XLV and type RECOSTAL® Keyboard XLW, depening on the respective requirement for edge protection. To withstand stronger shear forces, the RECOSTAL® Keyboard XLV/XLW unit can also be equipped with dowel bars. The available RECOSTAL® Keyboard XLV/XLW variants are used to create dilatations.
