Retaining Wall Fixes

Simple answers to leaning walls, trapped water problems, and building structures that never move.

01 Why do retaining walls start to lean or bow out?

Walls don't fail because the soil is too heavy—they fail because of trapped water. When heavy rain falls, the ground behind the wall turns into heavy, wet mud. If that water has nowhere to go, it builds up immense hydrostatic pressure that slowly pushes the entire wall forward.

THE REMEDIAL FIX: We drill out drainage relief weep holes, clear away blocked soil, and backfill the area with clean, washed gravel so water can drop straight down and escape safely instead of pushing against your structure.

AVOID WALL COLLAPSE

STOP WATER PRESSURE

Most walls lean because of trapped water. We install High-Flow Ag-Lines and Geofabric Filters to move water away fast, protecting your wall from heavy mud pressure and collapse.

02 How do we fix timber walls that are rotting away?

Old timber sleepers naturally rot, warp, and weaken when buried in damp dirt for years. Once the wood begins to decay or gets eaten by termites, the structural backbone of the wall disappears, making it highly susceptible to sudden collapses during storm seasons.

THE REMEDIAL FIX: We replace failing timber elements with solid, commercial-grade retaining products. We sink deep concrete footings below the frost and movement lines to lock the new structural supports permanently in place.

TOTAL PEACE OF MIND

NO MORE ROTTING WOOD

Tired of timber walls rotting or attracting termites? We only use Galvanized Steel H-Posts and Reinforced Concrete. It is a permanent solution that stays straight and strong for decades.

03 Do I need an engineer to fix a retaining wall?

Any wall holding up earth near boundary lines, driveways, or heavy building foundations is a serious load-bearing structure. Slapping together a quick landscaping fix without calculating the proper weight distribution can lead to severe property damage and legal liabilities.

THE REMEDIAL FIX: We handle everything from soil weight calculations to council compliance. Our team ensures the wall is built with the correct base mass, steel reinforcement, and gravel drainage layers to handle any soil load.

GUARANTEED PROTECTION

STRUCTURAL SECURITY

Every wall we build is backed by a 6-Year Workmanship Warranty and follows Australian Engineering Standards. You get a certified structure, not just a quick "landscaping" fix.

Structural Wall & Drainage Fix

SYSTEM: Concrete Sleeper / Steel H-Post

AREA: 10m² Base Wall

ENGINEERING: Certified Design

01. THE PROBLEM

The old wall was leaning and ready to fall. This happened because there was no drainage (Ag-line) behind the wall. When it rained, the soil got heavy like mud and pushed against the wall. The owner was worried about the wall collapsing into the neighbor's yard.

02. OUR SOLUTION

We built a new, stronger wall using reinforced concrete sleepers and galvanized steel posts. We did deep site research to test the soil. Most importantly, we installed a full Ag-line drainage system with blue metal rocks to make sure water never pushes against the wall again.
