Reinforcement over cavities

Collapses are represented by crater-like subsidences on the ground surface, generally appearing suddenly. They occur through the collapse of subterranean cavities, growing upwards in time until the finally break trough the surface. In areas, prone to subsidence hazards preventive stabilization for civil structures such as new roadways is required. Geosynthetic reinforced earth structures being used below the transport route subgrade are an adequate technique to overbridge the endangered cone. Temporary as well as permanent safety concepts using geosynthetic reinforcement are possible.
