What Gilberton is built on
Before anything is priced in Gilberton
Gilberton is 3.3 km north-east of the Adelaide CBD and inside the 60 km service area. The ground is recorded as alluvial loam over clay near the River Torrens, with level ground stepping gently down to the river, so the retained height, the soil being held and how water leaves the wall decide the design. Levels, access and the condition of what is already there are recorded so the quote reflects the real job.
How it goes
The build sequence at Gilberton
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 Gilberton
The retaining wall work problems that come up
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 Gilberton
Retaining Walls in Gilberton — FAQs
Do you cover Gilberton for retaining wall work?
Yes. Gilberton 5081 is about 3.3 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 stops a retaining wall failing?
Two things: footings that reach competent ground, and drainage that lets water out from behind the wall. Water is what loads a wall beyond its design, so ag-pipe, geofabric and screened aggregate backfill sit in every scope rather than being treated as an optional extra.
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.
