Retaining Walls Wentworthville
Concrete sleeper, besser block and sandstone retaining walls built by a team based right here in Wentworthville.
Retaining Walls in Wentworthville
Our workshop is on Garfield St, so Wentworthville is the suburb we know best. The ground here is shale derived clay running down towards Toongabbie Creek, moderately to highly reactive, and the housing is a mix of original postwar cottages, 1970s brick homes and a rising number of duplexes and granny flats. Most blocks have a gentle fall from the street to the rear, enough that half a metre to a metre of retention makes the difference between a sloping yard and a usable one.
We build the full range from here. Concrete sleeper walls on galvanised H beams for boundaries and rear yards, core-filled besser block for driveway cuts and secondary dwellings, sandstone for garden terraces and low timber for planter edging. Every structural wall gets a slotted agi line in clean aggregate behind geotextile, plus weep holes through block faces, and the outlet is piped rather than left to find its own way.
Walls above 1 metre, and anything retaining a driveway, pool or the neighbouring block, are engineer designed and taken through Cumberland City Council where approval is required. Being local means we can measure quickly, and every Wentworthville NSW 2145 job is priced with a fixed written quote. Call 0492 879 796 to book yours.

Retaining Wall Options in Wentworthville
Concrete Sleeper Walls
The everyday structural wall for Wentworthville yards, using galvanised steel posts and concrete sleepers that outlast timber many times over.
Block Retaining Walls
Core-filled besser with vertical reinforcement, our pick for driveway cuts and the ground behind a new granny flat.
Sandstone Terraces
Sawn or random sandstone that suits the older brick homes around the station and needs no maintenance at all.
Secondary Dwelling Retention
Walls sized and timed to suit a granny flat build so the slab crew is never waiting on the retention behind them.
Garden Edging
Low timber or block planter walls that tidy up a sloping front garden without needing engineering or approval.
Drainage First
An agi line in aggregate behind every wall we build, because in local clay the drain is what keeps the wall vertical.

Retaining Walls Wentworthville FAQs
When does a Wentworthville retaining wall need council approval?
Once it passes 1 metre in height, or when it retains a driveway, a pool, a structure or your neighbour ground, Cumberland City Council will generally want engineered plans and an approval. Under a metre, unsurcharged and clear of boundaries and easements, most garden walls sit within exempt development. Because we are based in the suburb we can drop past and give you a straight answer on which side of that line your wall falls.
Why do local retaining walls start to lean?
Because water builds up behind them. The clay through Wentworthville and down towards Toongabbie Creek drains slowly, so a wall with no subsoil drain ends up holding saturated soil rather than damp soil, and the difference in load is enormous. Add rotting timber posts on the older walls and the outcome is predictable. A slotted agi line, clean aggregate, geotextile and a piped outlet remove the pressure that causes the lean.
Should I rebuild my old timber wall in timber or concrete?
Concrete, in almost every case. Treated pine in local clay stays damp at ground line and typically gives 10 to 20 years before rot or termites finish it. Concrete sleepers in steel H beams do not rot, are not on the termite menu, and the steel posts can be driven far deeper than timber ever practically is. If the wall is tall for its length or carries a driveway, core-filled block is stronger again. Timber is fine for a garden bed edge and little else.
My neighbour and I both want the wall, how do we split it?
Retaining walls are not dividing fences, so there is no automatic sharing rule. Responsibility generally sits with whoever created or benefits from the change in ground level, but when both households gain from the wall a written agreement on the split before work starts is the simplest path. We are happy to issue the quote in a way that separates the retaining structure from any dividing fence above it so the arithmetic is obvious.
Can you put the fence up on top of the wall as well?
Yes, and we do both trades so it happens on one job with one point of contact. The fence load has to be built into the wall design because a 1.8 metre Colorbond panel catches a lot of wind at the top of a structure. We usually run the retaining posts up to carry the fence rails. You end up with a straight fence line, no gap underneath and no second mobilisation cost.
