Question 1

Do I need approval for a retaining wall in Strathfield?

Accepted Answer

Under 1 metre, clear of boundaries and easements and with nothing loading the ground above, a wall commonly falls within exempt development. Over 1 metre, or where the wall retains a driveway, pool or the neighbouring garden, Strathfield Council will require engineered plans and an approval. Heritage conservation areas and significant trees add another layer here, so we always check the property listing and any tree protection requirements at the measure.

Question 2

Sandstone or block for a Strathfield garden wall?

Accepted Answer

Sandstone is the traditional inner west answer and looks right against period brickwork, but it is heavier to handle, needs good access and takes longer to lay. Core-filled besser block is stronger per millimetre of thickness, can be rendered to match the house and is the better structural choice for tall or heavily loaded walls. Many Strathfield jobs use block for structure with a sandstone cladding or capping so the wall performs one way and reads another.

Question 3

Who is responsible for a shared retaining wall in Strathfield?

Accepted Answer

Retaining walls are not dividing fences, so the automatic cost sharing under fencing law does not apply. Responsibility generally sits with the owner whose works created the level difference, or who benefits from it. Where an old shared wall between two Strathfield properties has failed, the practical route is a written agreement on the split before anyone commits. We can price the retaining structure and any fence above it separately so the numbers are transparent.

Question 4

Why do old Strathfield sandstone walls bulge?

Accepted Answer

A century ago walls were often dry stacked or laid with lime mortar straight against the soil, with no subsoil drain behind them. Over decades the clay behind saturates, fines wash into the joints and the wall slowly rotates forward. Tree roots from mature gardens add to it. A rebuild that keeps the original stone face but adds a slotted agi line, clean aggregate and geotextile behind it gives you the same look with none of the movement.

Question 5

How is a Strathfield retaining wall quoted?

Accepted Answer

After a free on-site measure, in writing, with a fixed price. Wall height and length matter, but in Strathfield access often matters more, since barrowing stone down a narrow side path takes far longer than driving a machine in. We also allow for spoil cartage, tree protection, engineering and any council approval. Everything is listed on the quote so you can see what each part of the job contributes.
