A capillary barrier is one option for surface closure of landfills. For covering landfills of municipal waste, European regulations require that surface sealing for class 2 waste be made up of two independent components. In most cases, this is satisfied by the combination of an artificial and a mineral sealing. The next development stage of the capillary barrier is the combined capillary barrier (Wohnlich, 2006a), intended as an alternative to conventional combined sealing. Prof. Dr. Stefan Wohnlich and his team at Ruhr-University Bochum undertook a series of laboratory experiments simulating capillary barriers in a tipping trough. The German association LAGA was made aware of the conducted research. The research should be focused on the combined capillary barrier and should particularly answer questions concerning the pressure and runoff condition of a combined capillary barrier. During my...
