Retaining Walls Tugun

Retaining wall options in Tugun

Retaining in sandy coastal soils

Close to the beach, soils are often sandy and free draining, which helps with water but means footings and post depth need to suit loose ground. Walls here tend to be about raised gardens, level changes on narrow blocks and holding back the ground beside driveways. Galvanised posts and fixings suited to salt air are worth specifying.

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 Tugun

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.

Our process

1. 01

   Site inspection

   We look at the slope, soil, existing wall condition, access for machinery, boundaries and what sits above and below the wall.

2. 02

   Design and material choice

   Timber, concrete sleeper or block, wall height and line, drainage and any steps or garden beds that go with it.

3. 03

   Fixed-price quote

   An itemised written quote, including engineering and certification where the wall requires it.

4. 04

   Excavation and footings

   Machinery access, cut and spoil removal, post holes or base preparation and concrete footings.

5. 05

   Build and backfill

   Wall construction, ag drainage, gravel backfill, compaction and capping.

6. 06

   Finish and handover

   Topsoil, clean-up and a walkthrough, with any engineering or certification paperwork handed over.
