Retaining Walls Mudgeeraba

Walls we build and replace in Mudgeeraba

Retaining walls on sloping blocks

Sloping blocks are where retaining walls earn their keep: terracing a backyard into usable levels, holding back a cut beside the house or creating a flat area for a lawn or play space. Water from further up the hill needs somewhere to go, so drainage behind and above the wall is planned first. Tiered walls can sometimes suit better than one tall wall, and design, height and load all affect what engineering or approval is needed.

Concrete sleeper walls in Mudgeeraba

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.

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.

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.
