What retaining walls cost
As a rough 2026 guide, a wall about a metre high runs from around $200 per metre for timber up to $700 or more per metre for sandstone and engineered block, with concrete sleepers in between. Height, access, soil, drainage and engineering move every number, which is why these are guide figures and quotes are free. Our retaining wall cost guide breaks down the ranges by material and the questions that make quotes comparable.
Why Shire walls fail
The Sutherland Shire is hard country for retaining walls. Steep blocks load walls from above, sandstone bedrock stops water soaking away and sends it sideways into the wall, clay pockets common around Menai and Bangor swell and push every wet winter, and bush-edge blocks collect runoff year round. Most local failures trace back to one missing thing: drainage. Water, not weight, is what kills walls here, which is why drainage behind walls gets its own page, and why a wall that is already moving should go straight to leaning or collapsed wall.
