Choosing Between Concrete Sleeper, Timber, Besser and Rock

Material is the question everyone asks first, and the honest answer is that the block decides it more than taste does. Four things do the work here.

  • Concrete sleeper. The default for anything structural. Steel posts into concrete footings with sleepers dropped between them. It handles height, it stays straight, it does not rot, and it finishes neatly against a fence. Most structural walls we build are concrete sleeper.
  • Timber sleeper. Still the right answer for low garden terracing where the look matters more than the load. It is warmer to look at and cheaper to build. It also has a finite life in the ground, which is worth knowing before you put one somewhere that will be hard to get back to.
  • Besser block. Core-filled and reinforced, rendered or left raw. Strong, and it suits walls that have to turn corners or carry something above them.
  • Rock. Either dry-stacked or as a gabion. It suits sloping, uneven ground and it looks like it belongs in this part of Melbourne, because the basalt under the northern suburbs is exactly what it is made of.

What rules a material out is usually height, what sits above the wall, and whether there is enough room behind it to build properly.

Drainage Is Not an Optional Extra

If a retaining wall in Melbourne fails, water is almost always the reason. Not the sleepers, not the posts, and rarely the workmanship on the face of it.

The ground through Melbourne's north is reactive clay over basalt. Clay holds water, and neither the clay nor the rock underneath lets it soak away. So water that gets in behind a wall stays there, and saturated clay is heavier than dry clay and pushes harder against the wall. That is a load pushing on the back of the wall every day it stays wet.

The fix is not complicated and it is not expensive relative to the wall. An aggregate zone behind the face, a slotted ag line at the base wrapped in geotextile so it does not silt up, and an outlet that discharges to a proper point rather than onto the neighbour. Every wall we build gets that as standard.

Where a wall is already leaning, water behind it is the first thing to look at.

Retaining Wall Builders, Contractors and Installers: What to Ask

Builder, contractor, installer: the trade uses all three and they mean much the same thing. What matters is not the word on the van, it is what the crew actually controls.

The question worth asking is whether the same business is doing the excavation, the wall and the spoil. A landscaper who subcontracts the digging, and a digger who subcontracts the wall, both add a handover where the cost and the blame can move. With us it is one crew and one program from the first cut to the last load out.

The second question is what happens if rock turns up. In Melbourne's north it often does, and the answer should be a machine on site rather than a variation and a wait.

The wall is usually one part of a bigger job. Getting the block to a level is a site cut, basalt in the footing trench is rock removal, and the line behind the wall is drainage. If you already have a wall and want it to last, read how to maintain a retaining wall, or pick your suburb.

How deep those posts go is the question we get asked most, and it is not a number anyone should give you over the phone. We have written up what actually decides post depth.
