Retaining Walls Gold Coast: Sleepers, Posts and Drainage Delivered

If you are searching for retaining walls on the Gold Coast, you are probably pricing a wall or about to build one. We are the supply side of that job: the sleepers, posts and drainage, on one order, with freight worked out to your suburb.

• Homeowners: a materials list and a delivered price to compare against a builder's quote, or to build a low wall yourself.
• Builders and landscapers: one order for the whole wall, with the delivery date confirmed before you pay.
• Not included: we do not build walls, design them or arrange installers.

The Gold Coast runs from flat, sandy beachside and canal suburbs to steep hinterland blocks, with fast growing cut and fill estates in the north. Each kind of site asks something different of a wall.

Beachside and canal blocks

Sandy soils drain well but hold less, and salt air is hard on steel. Hot dip galvanised posts are the standard for these sites.

Hinterland slopes

Mudgeeraba, Tallebudgera and Currumbin Valley have steep blocks and heavy rain. Walls here are often taller and usually need an engineer's design.

Northern growth estates

Coomera, Pimpama and Ormeau are mostly cut and fill blocks, with boundary walls and a fence on top.

A concrete sleeper wall is made of two parts. Steel posts are set in concrete in the ground, and steel reinforced concrete sleepers slot between them, one row on top of the next.

• Sleepers: plain or patterned, in lengths of 1.6 m, 2.0 m and 2.4 m.
• Posts: retaining wall posts in H, C and corner profiles, sized to the sleeper thickness and the height of the wall.
• Finishing: accessories such as post caps, edge capping and fence brackets.

Summer storms on the Gold Coast can put a great deal of water behind a wall in a short time. Water that cannot drain adds weight and pressure, and it is the most common reason walls fail.

Every wall needs slotted pipe at the base, geofabric to keep soil out, and a band of drainage gravel behind the sleepers, with an outlet that carries the water away.

1. Measure the wall. Note the length and height of each run, and anything the wall will carry, such as a fence or driveway.
2. Build your list. The retaining wall calculator turns those measurements into sleepers, posts and drainage.
3. Send it as a quote. Add the list to your cart and send it to us with your delivery suburb.
4. We confirm freight and the date. You see the delivered price and the delivery date before you pay.
5. Delivery to site. Canal blocks, hinterland driveways and busy beachside streets each need a different truck. Tell us about access when you order.

In the City of Gold Coast area, as elsewhere in Queensland, a wall over 1m high, or one carrying a load such as a driveway, fence or building, generally needs an engineer's design and building approval. Rules vary, so check with the council or a building certifier before you order.

We can pass on the supplier's engineering for the sleepers and posts you choose, for your engineer or certifier to check. We do not design walls or issue certificates.
