Limestone block retaining walls
Reconstituted limestone blocks laid in running bond on a compacted base — the standard for new-block levelling in Alkimos, Brabham and Landsdale. Clean face, square corners, easy to render or leave raw.

Holds the block, keeps the sand. Reconstituted limestone, natural-cut Tamala limestone and concrete-sleeper walls, built on a compacted base with the drainage behind — priced by length and height before we come out to measure.
A wall is only as good as what's behind it — ag-line and blue metal in every one.
One metre high, twelve metres long
Behind every wall, left to right of the cut: retained sand · blue-metal drainage · 100 mm ag-line to stormwater · compacted base & footing.
Included in every wall: excavation to footing depth, compacted base, 100 mm ag-line and blue-metal drainage behind the face.
Walls & prices
Every rate is per square metre of wall face — length times height — and every wall includes the footing, the base and the drainage. Steps, returns and curves are measured on site.

Quarried Tamala limestone, cut and coursed by hand — the wall the neighbours ask about. Heavier, slower, and worth it on a front boundary or a pool surround where the stone is the finish.
Smooth or sandstone-face concrete sleepers dropped between galvanised steel posts concreted into the ground. The fastest, sharpest-priced wall for a side boundary or a driveway cut.
Most Perth councils need a building permit for any wall over 500 mm. We have the wall designed, certified and lodged with your council before a block goes down — you sign, we chase.
1.8 m Colorbond panels on posts set into the wall while we build it — one crew, one visit, one straight line along the boundary. Priced per lineal metre of wall.
Stairs through the wall, corner returns, radius walls and anything over 1.5 m all change the footing and the drawing — we measure them on site and quote from the engineer's design.
Every wall type includes excavation to footing depth, a compacted base, 100 mm slotted ag-line to stormwater and blue-metal drainage behind the face. Removal of an existing timber wall is $45 per lineal metre.
What the block owners say
"Our Alkimos block dropped 900 mm across the back and the pool company wouldn't start until it was level. Tamala Line had the blocks in, the drainage behind and the pad ready in a week — the pool went in a fortnight later."
"The pine wall along our side fence in Kingsley had been leaning for years and the neighbour was nervous. Old wall out Monday, sleepers and posts in by Tuesday afternoon, and they swept the verge before they left."
"We went natural-cut for the front of the Brabham place and it's the thing people stop and look at. Three neighbours have asked who built it. Straight, dry after the winter, and the permit was handled without us lifting a finger."

Where we work
We run north up the coast to Two Rocks and east through the Swan Valley to the hills foot — the two corridors where the new blocks are being cut and the old pine walls are giving up. Anywhere else in the metro is a phone call.
Questions we get on every block
Honestly, usually — most Perth councils require a building permit for any wall over 500 mm, and some ask for engineering on lower walls near a boundary or a pool. We have the wall designed and certified by a structural engineer and lodge the permit with your council; that's the $650 line in the planner, and it's locked on above 500 mm because it isn't optional.
Blocks are the all-rounder: clean, square, cost-effective, easy to render later. Natural-cut Tamala is the premium finish — heavier stone, hand-coursed, slower to lay, and it's the wall people notice. Concrete sleepers on steel posts are the fastest and cheapest per square metre and take a lot of load, but the posts and joints are part of the look. Where you'll see the wall every day, spend on the face; where it's a side boundary doing a job, sleepers are the honest choice.
A typical 12 m wall is two to three days on site once the footing has cured — day one is excavation, base and footing, then the courses, drainage and backfill. Natural-cut adds roughly a day; sleeper walls are usually quicker. Permit lodgement runs ahead of that and depends on the council's queue, which we'll tell you at the measure.
Every wall we build has a 100 mm slotted ag-line at the base and a column of blue metal behind the face, wrapped and run to stormwater or a soak. Water is what moves walls; the drainage is included in every price on this page, not an extra.
Usually the block that needs the fill held — the higher side — but it depends on your subdivision plan and any notifications on your title. Check the plan first and talk to the neighbour before the measure; if you both want the wall and a fence on top, we'll quote it as one job and you can split it however you agree.
Book a site measure
A site measure is free across the northern and eastern corridors. We check the levels, the drainage run and the boundary, then confirm the planner's number in writing.
