Retaining walls Newcastle: pick a system
Concrete Sleeper Retaining Walls
Steel-reinforced concrete sleepers set between galvanised H-posts - the workhorse wall for the sloping blocks across Newcastle's ridge suburbs.
Timber Sleeper Retaining Walls
H4-treated pine and hardwood sleeper walls for garden terracing, low boundary retaining and level changes under 600mm.
Besser Block Retaining Walls
Core-filled, steel-reinforced concrete block walls for taller engineered retaining and rendered finishes on tight inner-city blocks.
Rock & Boulder Retaining Walls
Natural sandstone and boulder walls battered back for a rugged, free-draining finish that suits the escarpment and bushland-edge blocks.
Gabion Retaining Walls
Rock-filled wire baskets that form a strong, free-draining wall suited to sloping and erosion-prone sites where surface water needs somewhere to go.
Retaining Wall Drainage & Subsoil Systems
Agricultural drain, gravel and geotextile drainage behind every wall - the structural detail that stops failures in Newcastle's reactive clay and coastal sand.
Engineered & Approved Retaining Walls
Walls outside the NSW exempt-development standards or carrying a surcharge, designed to AS 4678 and taken through the Complying Development Certificate or Development Application pathway.
Retaining Wall Repairs & Replacement
Assessment, repair and full replacement of failing, bulging or cracked retaining walls across Newcastle and the Lake Macquarie fringe.
