Retaining Walls That Hold Their Ground
A retaining wall is only as good as what’s underneath it. That’s why proper footing depth, base shaping and clean backfill are essential. We assess site conditions—soil type, drainage needs and access—then excavate to meet both structural plans and environmental factors.
Whether you need a single wall to flatten out a yard or a full tiered system to hold back a slope, the approach is always tailored to your site. We also support landscapers and builders by prepping trenches ahead of wall installs, avoiding delays once construction begins.
Backfilling is just as important. Poorly packed or unstable fill can cause walls to lean or crack over time. We take care to backfill with suitable material and compact in layers, reducing the risk of shifting and helping with drainage.
Do retaining walls need drainage behind them?
Yes—drainage is critical. Water pressure can build up behind a wall and cause structural failure. Most systems require an aggregate drainage zone with agricultural (aggie) pipe behind the wall to direct water away.
Without this, even well-built walls may bulge or collapse over time. Good drainage also reduces erosion and helps preserve the backfill material.
What materials can retaining walls be built from?
Common materials include timber, concrete sleepers, masonry blocks, natural stone and reinforced concrete. The right material depends on the purpose, budget, design preference and soil type. Some materials are better suited to taller or load-bearing walls, while others work well for landscaping or garden borders.
A solid base and correct wall construction are essential regardless of the material.
Do I need council approval for a retaining wall?
In many areas, yes—especially if the wall is over one metre high or supports a load such as a driveway or building. Local councils may also require approval for walls near boundaries or waterways.
It’s best to check regulations before starting work. Engineers often need to certify wall designs, and inspections may be required during or after construction.
What types of retaining walls do you construct?
The best material is the one that suits your style & budget. Treated pine or concrete sleepers. Gabion cages, stacked stone, sandstone blocks or a poured wall are a few options. They all have their own advantages and disadvantages.
Access and the slope you're trying to retain could be part of the discussion in making your decision.
The cheapest we offer is treated pine, then you could use galvanised post, concrete sleepers.
We're also able to form a retaining wall and pour a vertical slab. Footings with brick or blockwork could be the look you're looking for. Large sandstone blocks look great with their natural colours and veins running through them—you'll notice each block has its own personality.
