Channel Lock is a precast Positive Interlocking Concrete Block System that is used in conjunction with a filter fabric underlayment. The unique octagonal shape of Channel Lock allows maximum block flexibility and greater system stability. Blocks may be installed with or without the use of polyester revetment cables, dependent upon the Engineer’s design.
Laboratory Tested according to FHWA-RD-88-181
