Retaining walls fail for two reasons: water and shortcuts. Soil behind a wall gets heavy when it's wet, and without drainage that pressure builds until the wall leans, bows or cracks.
Every wall we build has properly set posts or footings for its height and soil, ag-pipe drainage at the base wrapped in sock or geofabric, clean gravel backfill so water can reach the pipe, and an outlet that goes somewhere legal. Walls over 1 metre — or close to a boundary, building or driveway — are built to an engineer's design.
Not sure which one? We'll talk you through it at the measure and bring samples.
Galvanised steel posts with reinforced concrete sleepers. Fast, tidy and long-lasting — $350–$600 per m² of wall face.
Besser block walls, steel-reinforced and core-filled with concrete. Ideal for taller or engineered walls — $500–$850 per m².
Formed and poured in place for maximum strength — basements, cut-ins and commercial sites. $650–$1,100 per m².
Natural sandstone blocks for gardens and feature landscaping — $550–$950 per m².
Treated pine or hardwood for low garden beds on a budget — $250–$450 per m².
Rock-filled steel baskets — free-draining and modern-looking. $450–$800 per m².

Australian premix pumped or barrowed in, screeded to falls, then finished — broom, trowel, coloured or exposed.
Control joints saw-cut, surface sealed, site cleaned up. You get care instructions and a slab that lasts.
Generally a retaining wall over 1 metre high needs a building permit and an engineer's design. Lower walls can also need one if they're near a boundary, building, driveway or easement, or hold up a load like a driveway. We'll tell you at the measure and can organise the engineering.
Timber sleepers are the cheapest up front, but concrete sleepers with steel posts usually work out better value because they don't rot. For most new-estate boundary walls, concrete sleeper is the sweet spot.
With galvanised posts set in concrete and good drainage behind, a concrete sleeper wall should last decades. Timber sleepers typically last 10–20 years depending on the treatment and soil.
It usually comes down to who changed the ground level. If you cut or filled your block, the wall is generally your responsibility. If you're sharing a wall with a neighbour, get the agreement in writing before work starts.
