Retaining wall work in Adelaide 5000: 0.01 km north of the Adelaide CBD and inside the service area. Below is what the work covers, the order it happens in, and what the written quote is based on. The ground at Adelaide is recorded as ground that moves with the seasons.
How it goes
From first cut to handover in Adelaide
Every job follows the same sequence, and the sequence is what makes the finished work hold up. Concrete sleeper, timber and besser block walls, with galvanised steel posts set in mass concrete and drainage behind every wall. Where the wall height or the site conditions require it, engineering and council documentation are coordinated as part of the job.
01
The failing wall is removed and the line is cleared back to honest ground
02
Post holes are augered to depth along the set-out line
03
Galvanised steel beams are stood plumb and concreted into every hole
04
Sleepers or blockwork are built up course by course between the posts
05
Ag-pipe, geofabric and screened aggregate go in behind the wall
06
The wall is backfilled, compacted and the fence above it reinstated
What Adelaide is built on
Ground, access and levels at Adelaide
Adelaide is 0.01 km north of the Adelaide CBD and inside the 60 km service area. The ground is recorded as ground that moves with the seasons, so the retained height, the soil being held and how water leaves the wall decide the design. Access to the work area, what sits under the existing surface, and how the block drains are all checked at the address before anything is priced.
Why AOI
What is included before work starts
Retaining Walls at Adelaide is priced from a written scope that lists what is included before anything is cut, dug or poured. The same team that scopes the work builds it, so the plan that is approved is the plan that gets built.

What to expect on a Adelaide block
The same handful of problems turn up again and again on this kind of work. Each one changes the scope, and each is priced as its own line rather than buried in a rate.
01
A garden wall that has quietly become a structural wall holding a metre of soil
02
Water trapped behind a wall because it was built without drainage
03
Rotted timber sleepers and rusted steel posts past their life
04
A boundary fence leaning because the wall beneath it has moved
05
A slope where the retained height changes along the run

What moves the number
A written quote follows the site visit at Adelaide. It sets out the scope line by line so you can see what is included, and anything found on site that sits outside the scope is quoted and approved before it is touched.
Questions from Adelaide
Retaining Walls in Adelaide — FAQs
Do you cover Adelaide for retaining wall work?
Yes. Adelaide 5000 is about 0.01 km north of the Adelaide CBD, inside the 60 km service area, and the work is quoted after a site visit at the address.
What happens to the fence on top of the wall?
Most boundary walls carry a fence. The fence is removed, the new wall is built with extended posts or fence brackets, and the fence is reinstated or replaced within the same job, so there is one handover instead of two contractors meeting at the same line.
How is a retaining wall priced?
By the linear metre and by the height the wall has to hold back, because height drives the engineering and the block size. Ground conditions, access for machinery and the drainage behind the wall all move the number, and the quote is fixed after the site has been inspected.
Can you build close to a boundary or a neighbouring structure?
Usually. Where access is tight the machine is sized to the gap and spoil is carried out in smaller loads, and where a fence panel has to come out to get a machine in, it is reinstated at the end. Anything within the boundary distance that triggers approval is identified before work starts.
Do retaining walls in South Australia need council approval?
Often. A wall that retains more than about a metre, sits close to a boundary, or supports a structure or driveway generally needs development approval, and lower walls that do not affect neighbouring land often do not. Every council reads site conditions differently, so the retained height, the boundary distance and what sits above the wall are checked during quoting, and the documentation is prepared where approval is required.
