Concrete sleeper, timber, sandstone and gabion walls, designed for your soil and slope, drained properly and council-compliant. We are licensed builders, not landscapers.
METCON builds durable, structurally sound retaining walls that manage slopes, prevent erosion and add lasting value to your property. Whether you are dealing with a sloping block, replacing an old wall, or levelling your land for landscaping, we deliver engineered, council-compliant results that stand the test of time.
Most walls fail because of water, not weight. That is why every wall we build gets proper footings, ag-drainage, aggregate backfill and weep holes as standard. It is the part that gets skipped, and it is why other walls end up leaning.
Every site is different. We recommend the wall that suits your soil, slope, budget and the look you want, and explain why.
Most popularGalvanised steel posts with reinforced concrete sleepers. Strong, neat and the best value for most Sydney homes.
Natural and warmTreated pine or hardwood sleepers, built on proper footings and drainage so the wall holds instead of rotting out.
Premium lookSawn or rough-cut sandstone blocks. A natural, timeless finish that suits older Sydney homes and gardens.
Drains itselfSteel mesh cages filled with natural stone. Strong, permeable and excellent on steep or uneven ground.
Over 1 metreReinforced concrete and block walls designed by a structural engineer for high loads, boundaries and slopes.
GroundworkSite cuts, footings and ag-drainage done properly underneath, because that is where walls fail or last.
A retaining wall is a structure, not a garden feature. We build it like one.
Soil type, height, drainage and any load on top. Engineered, signed off and certified.
Ag-drain, aggregate and weep holes on every wall. The step that stops walls leaning.
We sort the DA or CDC and engineering, so you never cop a stop-work notice.
You deal with the people building it. Same number from first quote to finished wall.

METCON replaced our failing timber wall with concrete sleepers. Straightforward quote, tidy site, and it looks fantastic.
Council approval sorted, engineering sorted, wall done in a week. Could not fault the process.
We got three quotes. METCON was not the cheapest but was clearly the most thorough. Worth every dollar.
Our sandstone wall was crumbling and the whole garden was sliding. Constantine came out the next day, explained everything clearly, and the new wall is rock solid.
We needed a large gabion wall for a steep commercial block. Engineered, certified, and done on time. Professional from start to finish.
I called three builders and METCON were the only ones who actually came to look at the site before quoting. Honest pricing, no surprises.
Timber retaining wall for our backyard garden beds. Neat, well-drained, and exactly what we asked for. The crew cleaned up every day before they left.
They handled the DA, the engineer, and the build. We didn't have to chase council once. Massive wall, done in under two weeks.
We're a strata block and needed a retaining wall replaced urgently. METCON moved fast, communicated well, and the residents are very happy.
Had a concrete sleeper wall built along our driveway. Perfectly level, well-finished, and the drainage is spot on. No more water pooling.
Our neighbours recommended METCON and now we know why. Reliable, fair price, beautiful sandstone wall. Would use them again without hesitation.
Two-tier sleeper wall on a steep slope. Other builders said it was too hard. METCON got it done, engineered and council-approved.

It depends on the height and location. As a general guide in NSW:
Rules vary between councils, so we always check the specific requirements for your area.
Costs vary with wall type, height, length, site access and soil conditions. See the price guide above for 2026 rates per square metre. Excavation, drainage, engineering certification and council fees may be additional. We give you a free, itemised quote after a site visit.
The best type depends on your site conditions, height, soil type, budget and the look you want.
We advise on the best option during your free site assessment.
A standard residential retaining wall typically takes 3 to 10 working days, depending on length, height, site access, and whether excavation or engineering is involved.
Walls that need council approval can take longer because of the approval process, which can add 4 to 8 weeks. We give you a realistic timeline with every quote.
Yes. METCON is a fully licensed NSW builder and every project is backed by full coverage:

Yes. We manage the entire approval process for you, including Development Applications (DA), Complying Development Certificates (CDC), structural engineering drawings and certification. You do not need to deal with council directly.
Yes. We regularly replace failing or damaged retaining walls. That includes removing the old structure, assessing the site and building a new engineered wall to current standards. Where the structure is still sound, we can repair it instead.
In almost every case, yes. Poor drainage is the number one cause of retaining wall failure. We install agricultural drainage lines, gravel backfill and weep holes as standard on every wall we build.
