A flexible revetment mat used to control soil erosion comprised of a plurality of blocks each having a hexagonally shaped grid held firmly together by tongue and cavity coupling means. The tongues and cavities are shaped to allow limited movement of each tongue within its associated cavity. The blocks may be placed into position with or without connecting cables. The shape of the blocks and location of through tunnels allows the use of cables. The blocks are preferably hexangular to resist horizontal hydraulic forces at various directions. |
