Retaining Walls in Gladstone

In Queensland, you’ll likely need council approval for a retaining wall if it’s over one metre high, located near a boundary, or supports a structure like a driveway or building. Walls under 1 metre may not require formal approval, but you still need to comply with building codes and drainage regulations. If your wall affects neighbouring land or is part of a shared boundary, it's best to consult with the council and inform adjoining property owners. It’s also wise to have a licensed contractor involved—they’ll help ensure your wall is safe, compliant, and built to suit your site conditions.

The best type of retaining wall depends on the slope, soil type, budget and the desired aesthetic. For steep blocks, engineered solutions like concrete sleeper walls or interlocking block systems are often the safest and most durable. These options provide strong support and can be reinforced to handle heavier loads. If you’re looking for a more natural look, rock or boulder walls can be a great choice and also help with water runoff. On gentler slopes or for garden beds, timber may be suitable—though it typically has a shorter lifespan. A site inspection will determine the right solution.

Timeframes vary depending on the size, type and complexity of the job. A small garden wall might be completed in one-to–two days, while a larger structural wall could take a week or more, especially if excavation, drainage, or reinforcement is required. Weather, site access and council approvals (if needed) can also impact the schedule. At CQ Fencing & Retaining Walls, we provide a clear project timeline upfront so you know exactly what to expect. The key is making sure the job is done right the first time—cutting corners can lead to costly repairs down the track.
