Soil Reinforcement Units for Retaining Structures
Double twisted steel wire mesh units used for reinforced soil structures and slope consolidation.
For structures with vertical facing units are made with hexagonal wire mesh continuous base panel for the reinforcement and the facing portion of the structure.
