Our panels are 60mm thick and contain steel reinforcing in accordance with AS 4671. All concrete exceeds 40Mpa. The posts are also reinforced with steel in accordance with this standard. Retaining walls up to 1500mm high with concrete posts, higher walls require steel posts that are always galvanised to stop rusting.
