Most retaining wall jobs in Mount Richon come back to one thing: the suburb covers the western slope of the Darling Range, so nearly every block has a cut or a fill. Walls here hold back real height and catch runoff from upslope, which makes footings and drainage the first questions, ahead of the face material.
The wall work Mount Richon homeowners raise most
New retaining wall installation suits terracing a sloping yard into usable flat ground, in limestone, block or concrete sleeper. Older walls often need retaining wall repair or better drainage. Where a driveway, shed or tank sits above the wall, an engineered retaining wall is worth discussing before anything is built.
Limestone, block or sleeper on an escarpment block
Limestone suits garden terraces and lower cuts where its weight does the holding. Block walls with reinforcement handle taller cuts and tidy lines along a driveway. Concrete sleeper walls go up quickly between steel posts and suit long, moderate rises. On steeper Mount Richon lots, the retained height usually narrows the choice before looks do.
Why drainage comes first on a hillside street
Water moving down the range does not stop at your boundary. Behind a Mount Richon wall it builds pressure, softens the ground at the footing and pushes the face forward over time. Retaining wall drainage, meaning gravel backfill, a slotted pipe and a clear outlet, matters as much as the wall itself here.
The City of Armadale and your Mount Richon wall
Mount Richon falls within the City of Armadale, not the City of Gosnells, so the City of Armadale's building guidance is the one to read before a wall goes in. Its information on what you can build covers when a retaining wall needs approval, and taller or loaded walls deserve the closest check.
When an older Mount Richon wall needs help
Leaning faces, bulging limestone, cracked blocks and damp patches at the base all point to pressure the wall was not built for. Repair can sometimes rebuild a section and add drainage; where the whole run has moved, rebuilding with proper footings is usually the sounder decision.
Your Mount Richon next step: walk the slope after rain
Walk the slope after rain and mark where water crosses the block and pools against the wall. Then note the tallest point of the cut, the wall length and anything heavy above it, like a driveway or shed. You can request a quote here, and a licensed and insured local contractor can follow up.
Local facts for Mount Richon
- •Parts of Mount Richon grew after the Armadale Brickworks and its shale quarry closed, so some lots sit on ground reshaped by past workings. It is worth checking what a wall's footing will actually bear on rather than assuming natural slope.
- •Homes around Tredale Avenue went up after Armadale High School opened in 1957, making them among the suburb's oldest. Garden walls from that era may be decades old and are the likeliest to need repair or drainage added.
- •The former Richon Cellars vineyard was subdivided in the early 1990s, along with land south of Tredale near the Schoenstatt Shrine. Walls on these estates are often original to the build, so check whether their drainage outlets still run clear.
