Frequently Asked Questions (FAQ)
Generally, yes. In South Australia, retaining walls typically require Development Approval (DA) if the wall:
- Exceeds 1 metre in height above the natural ground level.
- Is constructed near a boundary.
- Involves creating or supporting surcharge loads (like a driveway or building above the wall).
We manage the entire application process, including coordinating necessary engineering reports, to ensure your wall is 100% compliant.
Hydrostatic pressure is the force exerted by water that builds up behind a retaining wall, which is the leading cause of structural failure.
As licensed civil and plumbing experts, we eliminate this risk by installing a full sub-surface drainage system (Ag Pipe) wrapped in geotextile filter fabric. This system ensures water is collected and safely diverted to your stormwater connection, protecting the wall's integrity and extending its lifespan significantly.
The 'best' material depends on your specific site conditions, required height, and aesthetic goals.
- Concrete Sleepers are often the most cost-effective and durable solution for high walls.
- Link Blocks / Keystone Blocks offer a clean, decorative finish.
- Natural Stone or Boulders provide the highest aesthetic value.
We will provide itemised quotes for multiple options during your free site assessment so you can make an informed decision.
The timeline varies significantly based on the wall's length, height, material chosen, and site access.
- A standard 10–15 metre wall can typically be completed in 3 to 5 days from excavation to backfill.
- Larger or more complex projects requiring significant civil work or engineering may take longer.
We provide a clear project timeline upfront during the quotation phase.
