What Hackney is built on
Before anything is priced in Hackney
Hackney is 2.17 km north-east of the Adelaide CBD and inside the 60 km service area. Levels, access and the condition of what is already there are recorded so the quote reflects the real job. The retained height, the soil being held and how water leaves the wall decide the design.
How it goes
The build sequence at Hackney
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
Common in Hackney
What to expect on a Hackney 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
Why AOI

Questions from Hackney
Retaining Walls in Hackney — FAQs
Do you cover Hackney for retaining wall work?
Yes. Hackney 5069 is about 2.17 km north-east 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.
