According the European approval ETA-15/0224, Kappema composite walls, the distance between the waves is fixed on a maximum of 80 cm. (center to center) 

According the approval ETA-15/0224 it is possible to make the layers with 45 mm concrete or more.

To simplify the planning with the KAP-Steel-Wave Kappema developed a software modul which can be connected with most CAD systems for precast industry on the market. The software enables to choose between different types of connectors for double walls and will place the waves automatically when creating the elements.
