Retaining Walls Sydney
Steep North Shore blocks need walls that hold. We build sandstone, core-filled block, brick and stone retaining walls on proper footings, with the drainage that stops them failing.
Retaining Walls, done right.
Most retaining walls fail because of water, not weight. Without drainage behind the wall, pressure builds up after rain until the wall bows, cracks or leans. Every wall we build includes the drainage and backfill it needs, and walls over the regulated height are built to an engineer's design.
We build new walls, replace failing timber and old masonry walls, and repair and repoint existing sandstone walls.

Everything the job needs, one team.
- Site assessment and height check
- Engineering arranged when required
- Excavation and reinforced footings
- Ag drain, gravel backfill and weep holes
- Core-filling and reinforcement for block walls
- Waterproofing to the back of the wall
- Caps and finishes to suit the house
- Steps and planters built into the wall
- Clean-up and excess soil removal
Built for Sydney slopes
Ku-ring-gai, Lane Cove and the harbour suburbs have some of the steepest residential blocks in Sydney. We have built walls on tight, sloping sites with limited access and know how to stage the work safely.
Engineering and approvals
Walls above the height allowed without approval, walls near boundaries and walls supporting structures need engineering and sometimes council approval. We work with engineers and build exactly to their details.
What goes into your quote
Every job is quoted after a site visit. These are the main things that change the price.
Height and length
Priced mainly by wall area and whether engineering is needed.
Material
Sandstone, block and brick differ in material and labour cost.
Access and excavation
Tight access and rock excavation add time.
Retaining Walls across the North Shore
Based in Lane Cove North, we work across Sydney with most jobs on the Lower and Upper North Shore.
Do I need an engineer for my retaining wall?
Walls above a certain height, or walls near boundaries or supporting buildings, usually need engineering. We will tell you when that applies and can arrange it.
What is the best material for a retaining wall?
Core-filled block is strong and cost-effective. Sandstone looks the part on North Shore properties. Brick suits walls that tie into the house. We will recommend what suits your site.
Why is my old retaining wall leaning?
Usually water pressure from poor or blocked drainage, or footings that were too small. We can advise whether to repair or rebuild.
Can you build steps into the wall?
Yes. We build steps, planters and seating into retaining walls in matching stone or block.
