Retaining walls for Coomera properties
If you are looking at a retaining wall in Coomera, the first question is not which sleeper looks best. It is what the wall has to hold back and where the water will go.
Coomera is a fast-growing northern corridor suburb with a wide range of estate housing.
2000s-onward estate homes, townhouses and older riverside properties.
Where your wall is likely to need engineering or approval because of its height, load or position, we tell you at the inspection and include it in the quote.
Walls we build and replace in Coomera
Retaining walls on newer estate blocks
Newer estate homes often come with bare or developer-built retaining along the boundaries and a yard that is not quite level. Common jobs are extending or raising existing walls, adding walls to create a flat lawn, and garden walls along fence lines. Estates may have covenants or developer guidelines, and walls near boundaries and easements need checking before design.
Steps and garden beds built in
A new wall often needs steps through it or a garden bed along it. Designing those with the wall gives a cleaner result than adding them later.
Concrete sleeper walls in Coomera
Concrete sleepers between galvanised steel posts are the most common wall we build. They will not rot, they suit most residential heights, and woodgrain or stone-look faces make them easy to match to the house. Post spacing and footing depth are set to the height and whatever sits above the wall.
Timber sleeper retaining walls
Treated pine and hardwood sleepers remain the most economical option for low garden walls. We use timber rated for ground contact, detail it to shed water, and are honest about its shorter lifespan compared with concrete.
Block and tiered garden walls
Segmental block walls suit curved lines and tiered gardens. They need a compacted base and drainage aggregate, and depending on the system and height, reinforcement back into the soil, so we plan the excavation footprint and access around that.
