Retaining Wall Sydney

Retaining Walls Specialists Working in Sydney

There is a pattern to retaining walls jobs in Sydney, where the housing is largely the full spread of Sydney housing, from Victorian terrace to new release estate. A whole street tends to reach the same point at the same time.

Most retaining walls enquiries we take in Sydney come from the same place: a wall that has begun to lean or bulge in the middle. It is worth understanding why that happens here before deciding what to replace it with.

We are based at Wentworthville and Sydney is well inside our regular run, so a site visit is a short trip rather than a scheduling problem.

The Faults We See Most Often in Sydney

Ask three contractors for retaining walls in Sydney and you may get three different answers. The difference usually comes down to whether anyone has looked at access constraints that vary from a wide western verge to an inner-west rear lane before pricing the job.

• Water weeping through the face because there is no drainage behind it
• A level change that was filled rather than retained
• Timber sleepers that have rotted at the base course
• A wall built without allowance for the driveway sitting above it

The Way We Run a Sydney Project

Services are located before excavation, every time. Around Sydney the older streets carry runs that are not where the plans say they are, and a strike is expensive for everyone.

We book a realistic program rather than an optimistic one. On reactive shale clay in the west, sandstone and sand through the coast and north, a couple of wet days stops excavation entirely, and an honest schedule allows for it.

• Repairs to failed and leaning walls
• Agricultural drainage behind every wall
• Timber sleeper walls
• Engineered walls with certification
• Segmental block and modular systems
• Concrete sleeper walls with steel posts

How We Manage Access and Disruption

Neighbouring properties, verges and driveways get protected. Around Sydney we allow for coastal salt exposure on one side of the city and cracking clay on the other, because a delivery in the wrong place causes more trouble than it saves.

We work out where the truck parks, where the material lands and where the spoil goes before quoting. On everything from flat river plain to steep sandstone escarpment, that is not a detail.

Materials and Specification

Everything we install carries a manufacturer specification, and we install to it. Warranty claims fail on installation detail far more often than on product defect.

The parts you cannot see once the job is finished are the parts worth paying for: footings, drainage, fixings and substructure. That is as true in Sydney as anywhere.

• A wall on reactive clay has to allow for the ground swelling behind it, not just the static soil load.
• A retaining wall fails because of water pressure far more often than because of the weight of soil.
• Concrete sleeper walls carry their load through the steel posts, so post embedment is the critical dimension.
• Stepping a large level change into two terraces is often cheaper and always safer than one tall wall.
• Drainage behind a wall is aggregate, a geotextile separation layer and an agricultural line taken to a legal discharge point.
