  • Soil reinforcement
    Patent number: 6224295
    Abstract: To secure a polymeric strip (5) to a facing (10) of a reinforced soil structure, the strip (5) is circumflected about a plastics rod (4) and the circumflected strip and the rod are interposed between two or more blocks (1, 2) in a cavity (7) to retain the rod and thereby secure the strip (5) to the facing (10). The location of the rod (4) within the facing serves to distribute more uniformly the load imposed by the facing (10) on the strip (5), and the plastics rod (4) is resistant to corrosion.
