Retaining Walls Broadbeach

Retaining wall work for Broadbeach homes

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.

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.

Replacing a leaning or rotted wall

When posts lean, sleepers bulge or soil washes through, repair rarely lasts. We remove the old wall in stages, support the soil, and rebuild with new posts, footings and drainage.

Repairs where they make sense

A rotted sleeper, a failed capping or a blocked drain can often be repaired if the posts and footings are sound. We check before recommending repair, and say so if replacement is the better spend.

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.
