The integral barriers on the front face prevent small animals from climbing into the danger area, while the front foot area suppresses vegetation and provides a clear movement area for animals. No metal reinforcement is used, so animals are not disoriented, while the non-absorbent surfaces, which have minimal thermal conductivity, provide an ideal surface for amphibians to move along.

Due to the design of the system and the strength of recycled polymer concrete, the ACO Guide Wall system can be used to retain substantial earth banks.
