Fernline Retaining Walls & Terracing
Half the Northern Beaches lives on a slope, and every leaning wall on the peninsula was built cheap by someone who skipped the engineering or the drainage. Walls over 600mm get engineered footings, certified design and agricultural drainage behind them. That is not gold-plating, it is the law and it is physics.
What this job includes.
- ✓Sandstone, masonry block and hardwood sleeper walls
- ✓Structural engineering and certification over 600mm
- ✓Ag-line drainage and waterproofing behind every wall
- ✓Terracing steep blocks into usable, planted levels
- ✓Repair-or-rebuild assessments on failing walls, honestly called
Seven lines, every job, no allowances.
Whatever the service, the proposal itemises the same way, so you always know what you are paying for.
- 1 The scaled design. A measured plan of your block, drawn to scale and signed off by you before anything is dug or ordered.
- 2 Site prep & drainage. Excavation, soil improvement and where the water goes. Priced as its own line, never buried in "site costs".
- 3 Structures, itemised. Deck, pergola, retaining walls and steps, each with its spec, footing detail and engineering where required.
- 4 Materials, named. Spotted gum or blackbutt, sandstone or block, named in the proposal so nothing gets quietly substituted.
- 5 The planting schedule. Every plant by species and pot size, chosen for your soil, sun and salt exposure, not a "$3,000 planting allowance".
- 6 Approvals & certification. DA, CDC or exempt, stated up front. Where approval or engineering is needed, the path and the cost are in the proposal.
- 7 Warranty & handover care. The 5-year structural warranty in writing, plus a 12-week establishment plan so the planting actually survives.
What happens, step by step.
Design visit & measure
We walk the block with you, measure it properly, and talk budget honestly. How you live outside drives the design.
Design & itemised proposal
A scaled plan with structures, materials and a full planting schedule, priced line by line. You sign off the drawing, not a guess.
Build, staged and tidy
Earthworks, drainage, structures, then planting, in that order. The site is left safe and tidy every single evening.
Plant & hand over
Planting to the schedule, mulch, irrigation checks, then a walkthrough against the plan and a 12-week establishment guide.
The paperwork behind the price.
Public liability to $20M, and a 5-year structural workmanship warranty, all in writing, all on request.
Structural landscaping over $5,000 in NSW legally requires a licensed contractor, and our licence number is on every contract. Public liability to $20M protects your property while we work, and the 5-year structural workmanship warranty covers the decks, walls, paving and drainage we build. Every plant on the schedule is backed by a 12-week establishment guarantee. Certificates of currency are yours on request before any deposit.
Retaining Walls & Terracing: common questions.
Do retaining walls need council approval in NSW?
Why is my old wall leaning?
Sandstone or block?
