We design, engineer, and build concrete sleeper retaining walls for residential and commercial sites across Sydney. Steel posts, precast sleepers, proper drainage. Engineered to hold, not lean.
Concrete sleeper walls are Sydney's most popular retaining wall system for good reason. They're strong, low maintenance, termite-proof, and work on most residential sites. But a sleeper wall is only as good as its engineering, its drainage, and the quality of its installation.
METCON builds concrete sleeper retaining walls engineered to suit the specific soil, height, and surcharge conditions of your site. Every wall is designed by a structural engineer, built with galvanised steel posts, and fitted with proper drainage.
Whether it's a simple 600mm garden wall or a 3-metre engineered retaining wall with a driveway surcharge, we build it to engineering standard, documented and certified.
If any of these sound familiar, it is worth a free site visit. We will tell you straight what your site needs.
Retaining walls create usable flat areas on sloping sites, concrete sleeper systems are ideal for most residential heights.
Timber retaining walls have a limited lifespan. Concrete sleeper replacement is stronger and lasts significantly longer.
Clean, neat concrete sleeper walls work well on boundaries with consistent face finish on both sides.
Surcharge loads from driveways and structures need an engineered wall system, not just stacked sleepers.
Walls over 600mm typically need engineering. Concrete sleeper systems have well-established design methods.
Unlike timber, concrete sleepers don't rot, won't attract termites, and don't need staining or treatment.

From simple garden walls to tall engineered retaining structures, we handle the full range of concrete sleeper construction.
Galvanised steel H-posts with concrete sleepers stacked between. Proper concrete footings, drainage, and geofabric. The go-to system for walls up to 1.2m.
Walls from 1.2m to 3m+ requiring structural engineering. Larger posts, deeper footings, specific sleeper thicknesses, and drainage design matched to soil conditions.
Multiple wall tiers stepping down a slope. Each tier independently engineered with appropriate setbacks and drainage between levels.
Clean-faced retaining walls on property boundaries. Level top for fencing, consistent finish both sides, and proper allowance for neighbour access.
Ag pipe, geofabric, gravel drainage layers, weep holes, and waterproof membranes where required. Proper drainage is what keeps retaining walls standing.
Galvanised steel H-posts set in engineered concrete footings. Post size, depth, and spacing matched to wall height and soil conditions.

Every retaining wall follows our structured five-step process. Designed by engineers, built by experienced retaining wall constructors.
We attend site, measure the wall length and height, assess soil conditions, note any surcharges (driveways, buildings), and identify drainage requirements.
A structural engineer designs the wall, post size and spacing, footing dimensions, sleeper thickness, and drainage specification matched to your site.
We excavate for the post footings and drainage system. Posts are set in concrete to the specified depth and alignment before sleepers are placed.
Concrete sleepers are placed between the steel posts. Ag pipe drainage is installed behind the wall with geofabric and gravel. Backfill is placed in controlled layers.
Engineer inspects the completed wall. You receive full documentation including design drawings, photos, and certification for council or your records.
Engineering drawings, construction photos, drainage documentation, and engineer certification. Everything you need for council approval and property records.
Every landscaper offers sleeper walls. Not every builder engineers them. We build retaining walls that are designed by structural engineers, drained properly, and built to last, not lean.
Every wall is structurally designed for your specific site, soil, and height conditions.
Ag pipe, geofabric, and gravel drainage behind every wall, because water is what makes walls fail.

Documentation and certification ready for council DA, CDC, or exempt development requirements.
Galvanised steel posts, quality precast sleepers, and proper concrete, no shortcuts on materials.
Hands-on Sydney building experience going back to the 1970s.
Real reviews from homeowners, strata and builders.
METCON replaced our failing timber wall with concrete sleepers. Straightforward quote, tidy site, and it looks fantastic.
Had a concrete sleeper wall built along our driveway. Perfectly level, well-finished, and the drainage is spot on. No more water pooling.
Two-tier sleeper wall on a steep slope. Other builders said it was too hard. METCON got it done, engineered and council-approved.
Straight answers from the builder. Anything else, just ask.
As a rough 2026 guide, concrete sleeper walls in Sydney cost around $400 to $700 per square metre. Taller engineered walls sit at the higher end. Excavation, drainage, engineering and council fees may be additional. We give you a free, itemised quote after a site visit.
It depends on the height and location. As a general guide in NSW:
We check your council's rules and handle the application for you.
In almost every case, yes. Poor drainage is the number one cause of retaining wall failure. We install ag-drainage, gravel backfill and weep holes as standard on every wall.
A standard residential wall typically takes 3 to 10 working days, depending on length, height, access and whether excavation or engineering is involved. Walls that need council approval can add 4 to 8 weeks for the approval process.

We build concrete sleeper retaining walls across Sydney and surrounding regions, from harbourside slopes to western suburbs estates.
Take a few photos of the slope, mark the approximate wall length and height, and send them through. We'll design an engineered concrete sleeper wall and give you a clear price. No pressure.
