Retaining Walls — Burnside 5066
Retaining Walls in Burnside, SA 5066
Burnside 5066 is 4.2 km east of the Adelaide CBD and inside the 60 km service area. The blocks here carry a steady rise toward the Hills face, with many blocks carrying a metre or more of cross-fall, so the wall is designed from the levels, with the retained height and the drainage behind it settled together. On a foothill slope retaining is what converts fall into usable yard. The wall is designed from the levels and the engineer's detail, cut and fill are balanced so soil is not carted away and bought back, and drainage is sized for run-off arriving from upslope.
What Burnside is built on
Ground conditions at Burnside
On a foothill slope retaining is what converts fall into usable yard. The wall is designed from the levels and the engineer's detail, cut and fill are balanced so soil is not carted away and bought back, and drainage is sized for run-off arriving from upslope. The block here carries heavy reactive black-earth clay over limestone at the foot of the escarpment, with a steady rise toward the Hills face, with many blocks carrying a metre or more of cross-fall.
How it goes
The order the work happens in at Burnside
The build follows a fixed order: the failing wall comes out, post holes are augered to depth along the set-out line, galvanised steel beams are stood plumb and concreted, sleepers or blockwork go up course by course, then ag-pipe, geofabric and screened aggregate go behind before backfill and compaction. Work at Burnside is booked around the foothills band, where winter run-off arrives from the slope above, so the stages that are weather sensitive are not left to chance.
01
Demolition: The failing wall comes out — rotted sleepers, rusted posts and slumped soil cleared back to honest ground.
02
Drilling: Post holes are augered to depth along the line. A wall is only as good as what's below it.
03
Steel: Galvanised steel I-beams are stood plumb and concreted into every hole.
04
Sleepers: Concrete sleepers drop down between the beams, course by course, to full height.
05
Backfill: Backfilled, compacted and swept clean — straight, plumb and built to outlast the house.

What goes wrong on Burnside jobs, and how it is avoided
The problems listed come off this ground and this housing stock rather than a generic list. Each one changes the scope, and each is priced as its own line rather than buried in a rate.
01
Ground: heavy reactive black-earth clay over limestone at the foot of the escarpment, which decides the footing, the wall type and the drainage behind it.
02
A scope that named one job on the quote and delivered another on site
03
Access or levels discovered after the price was agreed, forcing a variation
04
Work sequenced out of order, so finished surfaces are trafficked by the next trade
05
Drainage left to chance, so the finished work moves or ponds in its first winter
06
A boundary detail agreed verbally with one neighbour and disputed by the other

Questions from Burnside
Retaining Walls in Burnside — FAQs
Do you take on retaining walls work in Burnside?
Yes. Burnside 5066 is 4.2 km east of the Adelaide CBD, inside the 60 km service area, and the work is quoted after a site visit at the address.
Can you build near a large tree in Burnside?
Usually, with the tree allowed for. Burnside sits on heavy reactive clay over limestone at the foot of the escarpment, and a large tree adds root and moisture considerations to any wall near it. The wall line, the footing depth and the drainage are set from the levels and the engineer detail, and where a significant tree is close, the siting and the root protection are worked out before the wall is built.
What happens to the fence on top of my old wall?
Most boundary walls carry a fence. We remove it, build the new wall with extended posts or fence brackets, and reinstate or replace the fence as part of the same job — one contractor, one clean handover.
