Retaining Wall Design & Certification
Structural calculations, construction drawings and an engineer's certificate for residential and commercial retaining walls — ready for council or your builder.
Certified retaining wall design, structural calculations and council-ready documentation — for homeowners, builders and developers. AS 4678 compliant, fast turnaround, and priced transparently before you commit.
From a single boundary wall to multi-tiered commercial retaining structures — designed to Australian Standards and ready for council submission.
Structural calculations, construction drawings and an engineer's certificate for residential and commercial retaining walls — ready for council or your builder.
Concrete sleeper, timber, block/masonry, gabion, sandstone and segmental block systems — engineered to suit your site, soil and budget.
State-specific documentation — including design certification and construction compliance forms — prepared correctly the first time.
Assessment of new, existing or failing retaining walls — with a clear written report on condition, safety and any repair requirements.
We coordinate soil testing and geotechnical reporting so your wall is designed for your site's actual ground conditions, not assumptions.
Pre-purchase, building defect and general structural inspection reports — for buyers, owners and property managers.
Drawings only matter if they're buildable. Every design accounts for how the wall will actually go together on site — access, sequencing, drainage installation and the realities your builder will face — not just what looks right on paper.
