Keystone

This product is made to order and price on application with lead times and minimum quantities applying.

Keystone from Austral Masonry is a robust and strong retaining wall system that can be used for constructing straight and curved walls for both residential and commercial purposes. A strong and secure retaining wall structure that features a patented interlocking pin connecting system, Keystone can be used for engineered walls up to 15m high, when designed by a suitably qualified engineer and combined with soil reinforcement.

Available in a range of colours, this system includes standard and flushface finishes for both the blocks and capping units, as well as standard corner units. Due to the cumbersome size and weight, Keystone blocks are used more commonly in large commercial projects and not so much residential jobs.
