Our Services

Retaining Walls

Concrete Sleeper Retaining Walls

Steel-post and concrete sleeper walls built for Illawarra slopes, with full behind-wall drainage so the wall stays plumb through every East Coast Low. Engineered heights, fence brackets and boundary installs across Wollongong.

Timber Sleeper Retaining Walls

Warm, natural timber sleeper walls built for Illawarra garden tiers and terraces, with full behind-wall drainage so treated pine and hardwood last in wet escarpment ground. Honest advice on when timber suits and when to step up to concrete, across Wollongong.

Besser & Concrete Block Retaining Walls

Core-filled Besser and reinforced concrete block walls built for the Illawarra, from rendered feature tiers to engineered structural spans. Steel-reinforced, fully drained and certified for height across Wollongong.

Interlocking Block Retaining Walls

Curved and terraced walls built from Keystone, Austral and link-block systems, with geogrid and full behind-wall drainage so the wall holds its line on Illawarra slopes. Segmental block walls for gardens, tiers and boundaries across Wollongong.

Sandstone & Stone Retaining Walls

Natural sandstone log, block and boulder walls built for Illawarra slopes, from dry-stacked garden tiers to crane-placed feature walls, with full behind-wall drainage so heavy stone stays put through every East Coast Low. Heritage-friendly stonework across Wollongong.

Boulder Retaining Walls

Sandstone and granite boulder walls built as gravity structures for large Illawarra slopes, each stone machine-placed, keyed and battered back with full behind-wall drainage, so a naturalised batter holds its line through every East Coast Low across Wollongong.

Gabion Walls

Rock-filled gabion cages built for Illawarra slopes, in galvanised, PVC-coated or corten mesh that drains every East Coast Low straight through the stone. Hand-packed faces, engineered heights and rugged feature walls across Wollongong, from coastal Thirroul to the escarpment foothills of Figtree.

Structural & Engineered Retaining Walls

Reinforced concrete, core-filled blockwork and piled retaining walls designed by a structural engineer and certified by a structural engineer, for high-load, surcharged and basement jobs on the steep Illawarra escarpment. Built to the stamped drawings across Wollongong, drainage and reinforcement engineered rather than guessed.

Retaining Walls on Sloped Sites

Terraced and tiered retaining walls built for steep Illawarra blocks, with benched cut-and-fill and drainage between every tier so the slope holds through each East Coast Low. Batter, boulder and concrete sleeper options across Wollongong, engineered and certified where the fall demands it.

Steel-Post (H-Post) Retaining Walls

Steel-post retaining walls built on hot-dip galvanised universal beam and channel posts, with concrete or timber sleeper infill and full behind-wall drainage. Coastal-grade galvanising for salt-exposed Thirroul and Port Kembla blocks, standard posts inland at Dapto, engineered and certified above 600mm across Wollongong.

Council Approval & Engineering Certification

Not sure whether a wall needs Council approval, a CDC or a full DA? The approval pathway, structural engineering to AS4678 and Wollongong City Council lodgement are handled in-house across the Illawarra, so the design, the certificate and the finished wall all line up.

Retaining Wall Repairs & Drainage

Leaning, bowing and cracked retaining walls put right across Wollongong, with drainage retrofits that fix the trapped water behind most Illawarra failures. Honest repair-versus-rebuild advice on rotted timber, shifted footings and post-East-Coast-Low damage from Figtree to Thirroul.

ABOUT US

Reliable Retaining Walls

Wollongong Retaining Walls is a local retaining-wall specialist working across Wollongong and the wider Illawarra since 2012. The business was built on a simple frustration heard across the region: walls put up cheaply and without drainage that lean, crack and fail within a few years on the escarpment's steep, wet ground.

Every wall is engineered around drainage first, from concrete sleeper and timber walls to Besser block, sandstone, boulder and gabion construction. The crew reads a Balgownie cut-and-fill block or a Thirroul beachside slope on sight, quotes it honestly with excavation and disposal included, and builds to the relevant Australian Standards. Fully insured to twenty million dollars, Wollongong Retaining Walls gives homeowners one reliable point of contact from the first measure to the final clean-up.

The crew excavates, sets footings, installs the wall with full behind-wall drainage, then clears the site and leaves the finished wall ready.
