Why it matters in Perth
Water pressure behind a wall is what pushes it over. Every wall we build has drainage behind it and compacted, free-draining backfill — the parts you never see but that decide how long the wall lasts.
Taller walls, walls near boundaries or walls holding up structures can need engineering and council approval. We will tell you at the site visit if your wall is likely to, and work with an engineer where it is required.
How the job runs
Assess the site
We check heights, soil, boundaries, access and where the water will go.
Plan & approvals
Choose materials and finish; we flag anything that needs engineering or council approval.
Build
Footings, first course laid level, drainage and backfill compacted as the wall goes up.
Finish
Capping, levelling the new terrace and cleaning up, ready for lawn, paving or planting.
Frequently asked questions
What is the best retaining wall for Perth?
Limestone blocks suit most Perth gardens and look natural. Sleeper walls are cost-effective for lower walls. Modular blocks are good for curves. We will recommend one based on height, load and look.
Do I need council approval?
Often for walls over about 500mm, on boundaries, or supporting buildings or driveways. Rules vary by council — we will flag it at the site visit.
Why did my old wall lean over?
Usually no drainage behind it, poor footings or the wrong backfill. We fix the cause, not just the face.
Can you build on a boundary with a fence on top?
Yes, with the right design — fence posts add load, so this is planned in from the start.
