Built for your site
Ground levels, soil conditions, nearby buildings, driveways, pools and access constraints are all considered before developing the design.
Drainage & Backfill
Subsoil drainage, free-draining backfill, filter fabric and waterproofing to manage water pressure behind the wall.
Footings & Foundations
Footing systems designed to resist sliding, overturning, bearing pressure and settlement for the specific wall type and ground conditions.
Wall Types
Gravity, RC cantilever, masonry, gabion, crib, reinforced-soil, anchored, timber sleeper, steel-post, sandstone and precast systems.
Standards & Certification
Designed to AS 4678, AS 3600 and AS 3700 with council-ready documentation and engineering certification.
02 — FULL ENGINEERING PRACTICE
More than a retaining wall?
Sydney Retaining Walls is the retaining-wall arm of BOICA NIB Consulting Engineers. The same registered engineer also handles new builds, alterations, footings and slabs, load-bearing wall removal, structural inspections, crack and foundation reports, plus stormwater and civil design — all certified and council-ready.
