Guide Wall

Prevents small animals from accessing danger areas

The system consists of standard 1m straight lengths, with additional elements to cater for changes in gradient or direction.

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.

The ACO Guide Wall can be used in conjunction with the ACO Tunnel Entrance, ACO Climate Tunnel and ACO Climate Stilt Tunnel to form a complete guidance and crossing system.
