Capping system for shielding of hazardous waste stored underground

The project participants developed a multi-link geotechnical sealing segment that prevents ingress of moisture to hazardous waste stored underground. The capping structure's operating principle is based on a granular layer that distributes fluids homogeneously between two seal segments by means of capillary rising, thus breaking up advancing moisture fronts.
