Common in Mile End

What to expect on a Mile End 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.

  1. 01

    A garden wall that has quietly become a structural wall holding a metre of soil

  2. 02

    Water trapped behind a wall because it was built without drainage

  3. 03

    Rotted timber sleepers and rusted steel posts past their life

  4. 04

    A boundary fence leaning because the wall beneath it has moved

  5. 05

    A slope where the retained height changes along the run

What Mile End is built on

Ground, access and levels at Mile End

Mile End is 2.71 km west of the Adelaide CBD and inside the 60 km service area. 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. The retained height, the soil being held and how water leaves the wall decide the design.

How it goes

How a Mile End retaining wall work job runs

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.

  1. 01

    The failing wall is removed and the line is cleared back to honest ground

  2. 02

    Post holes are augered to depth along the set-out line

  3. 03

    Galvanised steel beams are stood plumb and concreted into every hole

  4. 04

    Sleepers or blockwork are built up course by course between the posts

  5. 05

    Ag-pipe, geofabric and screened aggregate go in behind the wall

  6. 06

    The wall is backfilled, compacted and the fence above it reinstated

Questions from Mile End

Retaining Walls in Mile End — FAQs

Do you cover Mile End for retaining wall work?

Yes. Mile End 5031 is about 2.71 km west of the Adelaide CBD, inside the 60 km service area, and the work is quoted after a site visit at the address.

Concrete sleepers or timber?

Concrete sleepers cost more up front and do not rot or host termites, which is why they dominate new work. Treated timber is cheaper and suits low garden walls where the retained height and the consequences of movement are small. The recommendation follows the height, the soil and what the wall has to carry rather than defaulting to one product.

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.
