Retaining Walls
Load-rated · Drained · Certified
Concrete sleeper and sandstone block walls, engineered for load and drained correctly. We hold back steep or failing ground and turn it into usable land that lasts.

Retaining walls & earthworks · Noosa hinterland
Concrete sleeper retaining walls, engineered drainage and earthworks across the Noosa hinterland. Owner-operated. Own plant. One local team, start to turf.
The whole job
No coordinating five subbies. Excavation, walls, drainage and finish handled in-house, sequenced properly, signed off to spec. You deal with the operator, not a project manager.
On-site evaluation — fall, soil, access, drainage paths and the engineering the job actually needs.
Wall design, certification and council paperwork managed so the build is compliant from day one.
Cut and fill, wall installation and subsurface drainage — executed in the right order, by one crew.
Fencing, turf and final compaction. Site left clean, level and ready for use.
Before / After
A cut and retaining-wall install in Doonan — reclaiming a steep slope of stepped garden beds as flat, structured, usable ground.
Same site, two angles — an honest before-and-after pair, not a matched-spot wipe. Graded and colour-matched; the "before" is left genuinely as-found.
Capabilities
Retaining walls are the specialty. The rest of the kit means a block gets reshaped end-to-end — without bringing in another contractor.

Load-rated · Drained · Certified
Concrete sleeper and sandstone block walls, engineered for load and drained correctly. We hold back steep or failing ground and turn it into usable land that lasts.


Subsurface · Surface
Subsurface and surface drainage for groundwater, pooling and erosion — diverted away before it undermines walls, slabs or driveways.

Cut & fill · Pad prep
Site cuts, land clearing, cut-and-fill and pad prep — the groundwork every build sits on.

Road base · Hardstand
Rural driveways, road base and Geo Hex hardstands — a cost-efficient, durable alternative to concrete or asphalt.

Colorbond · Timber · Turf
Colorbond, timber and aluminium fencing, plus turf prep and lay to finish the job to a clean line.

Excavation · Spoil cartage
Pool excavation and surrounds, plus efficient spoil cartage in our own tip trucks — site left clean and ready.

Vegetation · Debris
Clearing overgrown, wooded or debris-strewn blocks back to workable ground, ready for the next stage.

Grading · Compaction
Grading and compaction to true, stable levels — the difference between a slab, drive or turf that holds and one that moves.

Own tip trucks
Muck-away and material haulage in our own tip trucks — no waiting on a hired truck, no mess left behind.
Why Adams
Built right, by the people who run the machines. The jobs others knock back are the ones we’re set up for.
We own the machines for the job — so there’s no hire markup, no waiting on availability, and timelines that actually hold.
Steep falls, tight access, unstable ground and water problems — the jobs others knock back are the ones we’re set up for.
Mitch runs the gear and the job. One accountable operator from quote to handover — not a rotating crew of subbies.
Where we work
Based in Cooroy, covering the hinterland blocks and acreage between Noosa and Gympie. Within the base zone, travel is included.
