Retaining walls across Cairns and the southern corridor
The ground changes faster across this city than almost anything else about it, and the ground is what decides the wall. A benched block at Brinsmead is cut foothill material with runoff arriving from higher up the hill. Gordonvale is Mulgrave alluvium where the question is what the soil can carry rather than how steep it is. Kewarra Beach is sand with almost no cohesion and salt working on every fixing.
Those are three different footings, three different drainage strategies and sometimes three different walls. That is why these pages are about soil, slope and water rather than about how long it takes us to drive there.
Foothills, estates, coast and flats
Eight suburbs with a page of their own, grouped by what the ground does rather than by the map.
- Brinsmead Benched foothill blocks with steep driveway cuts and water arriving from higher up the hill.
- Kanimbla Hillside estate blocks with tall batters behind the houses and serious volumes of water off the range.
- Bayview Heights Elevated southern slopes where the original subdivision earthworks are now reaching the end of their life.
- Mount Sheridan Estate homes on cut-and-fill pads, where most walls sit on or near a boundary and access is tight.
- Mooroobool Where the slope meets the flat, on heavier ground that holds water and moves when it does.
- Freshwater Where the creek flats meet the range, and blocks have real drainage lines running across them.
- Kewarra Beach Sandy coastal ground with very little cohesion, and salt in the air working on every galvanised fixing.
- Gordonvale Mulgrave alluvial flats where the question is what the ground can carry rather than how steep it is.
Where is the block, and what is the fall?
Give us the suburb and roughly how much height you need to hold. If it is outside what we cover you will hear that immediately rather than being chased.
- On site
- Monday to Friday 6.30am to 4pm, Saturday mornings
- Covering
- The western foothills, the estate suburbs, the northern beaches and south to Gordonvale
- Quotes
- Measured on the block, given in writing, no obligation
- We stand on the block before anybody talks about a number, because a slope cannot be priced from a description
- The quote states the height, the material, the footing, the drainage and where the spoil goes
- If engineering or approval is needed it is priced in, not added once the machine is already on site
