Licensed retaining walls for Gregory Hills homes and businesses, with a free on-site measure.
The retaining walls we install around Gregory Hills has to deal with reactive clay over engineered estate fill and with post-2013 estate homes with compact yards and a large business park nearby. Those two things between them explain most of what we recommend and most of what we advise against.
Retaining Walls in Gregory Hills is as much about access and set-out as it is about materials. On graded pads with consistent falls between adjoining lots, getting the sequence right is what keeps a job to program.
Most retaining walls enquiries we take in Gregory Hills 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.

Rubbish and old material leave with us. Around Gregory Hills, dealing with estate guidelines that still govern what appears on the street frontage makes storing a pile of demolition on site awkward for everyone, so removal is priced in rather than added later.
We photograph the site before we start and again at completion. On a Gregory Hills job that record settles most questions about what was there and what changed.
Every retaining walls quote we write for Gregory Hills starts on site, with photographs, levels and a walk of the full run. You cannot allow for new pools going in behind fences that were never designed as pool barriers from a satellite image.
Neighbouring properties, verges and driveways get protected. Around Gregory Hills we allow for level differences between pads that the boundary has to resolve, because a delivery in the wrong place causes more trouble than it saves.
We agree the working hours and the access route with you at the start. On the tighter Gregory Hills streets that conversation saves a day, and it saves the relationship with the neighbours.
Tree cover and root zones matter around Gregory Hills. Roots are worked around rather than cut through, both because the tree matters and because a cut root under a footing is a future problem.
One thing specific to this part of the south west growth area is a business park and commercial precinct with different security needs entirely. It is easy to miss on a first look and expensive to discover once work has started.
We allow for narrow side access with services and a meter box in the way because it drives material selection more than aesthetics do. Specifying around it costs a little more once and saves replacing the job early.
Galvanised steel posts with concrete sleepers dropped between, the current standard for domestic walls.
Treated hardwood sleepers where the look suits the garden and the height is modest.
Aggregate, geotextile and agricultural line behind every wall, because water is what pushes walls over.
Modular block systems that step back as they rise and suit curved alignments.
Rebuilding leaning and bulging walls, and correcting the drainage that caused it.
Designed and certified walls where height, surcharge or slope take the job past the standard details.
Concrete sleepers with galvanised posts are the current default because they are durable, quick to build and easy to make straight. Timber suits lower garden walls where the look matters. Block systems suit curves and terracing. Around Gregory Hills, the choice is often narrowed by narrow side access with services and a meter box in the way before appearance comes into it.
Retaining on or near a boundary raises both engineering and neighbour questions, because excavation affects the adjoining land and the wall may need to be built entirely within your own. It is worth resolving before work starts. Camden Council controls and the relevant survey are the starting point.
It depends on height, proximity to the boundary, and whether anything is loading the top of the wall. NSW exempt and complying development provisions set thresholds, and Camden Council applies its own controls over the top of them. Anything close to a boundary, near a drainage easement, or carrying a driveway above it should be confirmed with the council and, where required, designed by an engineer.
Sometimes, and it depends why it is leaning. If the drainage failed, correcting the drainage and rebuilding the affected section can work. If the wall was never built for the load above it, rebuilding to the right design is the only honest answer. We excavate a test section before committing either way.
Once height, slope or surcharge takes it past the standard details, and always where a structure, driveway or pool sits within the zone of influence behind the wall. On graded pads with consistent falls between adjoining lots around Gregory Hills this comes up more often than on flat ground. The honest position is that a certifying engineer is cheaper than a failed wall.
