Common retaining wall types in Wellard

Most walls around Wellard are one of these three. The right one depends on height, space, what the wall holds up and the look you want. The builder who quotes can talk you through it.

Limestone blocks

The classic Perth retaining wall. Large cut limestone blocks are stacked in courses, often stepped back slightly as they go up. They suit garden and boundary walls and look at home in older and newer streets alike.

Worth knowing

  • Blocks are heavy, so access for a machine matters.
  • Joints can let sand through without fabric or good packing.
  • Taller walls may need engineering.

Concrete sleepers

Concrete sleepers slot between steel posts set in concrete footings. They take up little space front to back, which helps on tight side setbacks and narrow yards.

Worth knowing

  • Post depth and spacing do the real work.
  • Fabric behind the sleepers keeps sand in.
  • Many colours and textures are available.

Besser block

Hollow concrete blocks, reinforced with steel and filled with concrete, on a concrete footing. Often chosen where a wall has to hold more, like a driveway or a slab close by, or where it will be rendered.

Worth knowing

  • Usually needs a proper footing and steel design.
  • Drainage and waterproofing behind matter.
  • Can be rendered or painted to match a house.

Where retaining walls go

From a low garden edge to a full boundary wall, these are the jobs people ask about most.

  • Garden walls and raised beds

    Low walls that hold a garden bed or edge a lawn. Often limestone or sleepers.

  • Boundary walls

    Walls along a side or rear boundary where your block sits higher or lower than next door. These often carry a fence too.

  • Pool area walls

    Walls that level the ground around a pool or hold back sand beside it. Plan them with the pool and its safety barrier.

  • Levelling a sloping yard

    Cutting a slope into flat areas for a lawn, patio or shed, sometimes with steps between levels.

Sandy soils and drainage behind walls

Many blocks around Wellard sit on sand. Sand drains fast, which helps, but it is loose. It can run out through gaps in a wall, wash away under a base that isn't compacted, and move when it gets soaked.

Water still builds up behind walls here, mostly from reticulation, downpipes and heavy winter rain. A wall that can't let that water out has more pushing on it. That's why most walls include gravel, an ag pipe and fabric behind them, with the pipe running somewhere the water can go.

This is general information. What your wall needs depends on the site, and the builder will decide the detail.

How water moves through sand behind a retaining wall: it soaks down to a gravel drain and an ag pipe, which carries it away. Rain and reticulation Water soaks quicklydown through sand Ag pipe carries it to a safe outlet Gravel lets waterreach the pipe

Height and council approval

Walls over a certain height usually need council approval. Walls on or near a boundary, and walls that hold up a driveway, fence or building, can have extra requirements and may need an engineer.

Wellard is in the City of Kwinana. Check with the City of Kwinana before work starts. The builder who quotes can usually tell you whether they expect approval to be needed and help with what to send in.

What affects the cost of a retaining wall

There's no fair price per metre without seeing the site. These are the things that move a quote up or down.

Height
Taller walls need more material, deeper footings and sometimes engineering. Height usually moves the price more than length.
Length
More metres means more blocks or sleepers, more base and more drainage.
Material
Limestone, concrete sleepers and besser block all price differently, and so do finishes and capping.
Access
Whether a small machine can get in, or blocks have to be carried through a narrow side path.
Site preparation
Digging out, moving or bringing in sand, and removing an old wall or tree roots.
Drainage
Ag pipe, gravel, fabric and where the water ends up.
What sits above
A driveway, fence, slab or pool near the top of the wall adds load and can change the design.
Approvals
Some walls need council approval or engineering drawings before work starts.

Questions people ask

Do I need council approval for a retaining wall in Wellard?

It depends on the wall. Height, where it sits and what it holds up all matter. Walls over a certain height usually need council approval, and walls on or near a boundary can bring in extra rules. Check with the City of Kwinana before work starts. The builder who quotes can usually tell you what they expect will be needed.

Which costs less, limestone blocks or concrete sleepers?

It depends on the job. The material is only part of the price. Height, length, access, footings and drainage often matter just as much. If you're not sure, ask for a quote on both.

Is sand a problem for retaining walls?

Sand isn't a problem in itself, but it needs care. It can run out through gaps, shift when it's wet and settle under a weak base. Walls on sandy blocks usually need a well-compacted base, good drainage and something to stop sand washing through, like geotextile fabric behind sleepers.

Do you build the wall yourselves?

No. Wellard Retaining Walls is a local quote-matching service. We pass your enquiry to an independent local retaining wall builder who services Wellard. They contact you, quote the job and do the work.

What should I have ready when I ask for a quote?

A rough length and height, what sits above and below the wall (lawn, pool, driveway, fence), how much side access there is, and whether an old wall needs to come out. Photos help once the builder gets in touch.

Does it cost anything to send an enquiry?

No. Sending an enquiry is free. Any price for the work comes from the builder in their quote.
