You’ve got a slope that isn’t holding, or a level yard you can’t have until something holds the dirt back. That’s what this is for — residential and commercial retaining walls, built to hold, across Gympie and the surrounding district. If you’re after a wall that stays put and drains properly rather than the cheapest stack of blocks, you’re on the right page.

Do we come to Gympie? We come to you across Gympie — homes and businesses alike, with the same team and the same call-out process throughout the area.

Retaining Walls in Gympie

You end up with usable ground. A wall that holds a slope back permanently, a level yard or driveway platform where there was a batter, and a finish you’re happy to look at from the house.

The wall is engineered for the load it’s actually carrying — height, the soil behind it, and whether there’s a driveway, pool or structure sitting near the top. Behind the face you get the parts nobody sees and everybody needs: proper footings, compacted backfill, drainage aggregate and an outlet that takes water away instead of letting it build pressure behind the wall. That hidden work is the difference between a wall that lasts decades and one that leans in a few years.

We work in the materials that suit the site — concrete sleeper, besser block, timber, rock — and we’ll tell you which one makes sense for your ground and your budget rather than selling you one system for every job.

How it works

First we come out and look. Height, fall, soil, what’s above and below the wall, and where water currently goes when it rains hard. That visit is what a real quote is built from — nobody can price a retaining wall properly from a photo.

You then get a written quote setting out the wall type, height, drainage and finish, and whether engineering or council approval applies at that height. If it does, we sort that before anything is dug.

On site: set out and excavate, footings in, then the wall goes up course by course with backfill and drainage placed as we climb rather than shovelled in at the end. We finish with the backfill compacted, drainage outletting where it should, and the site cleaned up.

You’ll know who’s coming and when, and you’ll be told if anything under the ground changes what we found at the quote stage — before we keep going, not after.

Why us

Retaining work above a certain height is building work, and in Queensland it has to be contracted by a licensed builder. Our QBCC licence number — 15489031 — is published in the footer of every page on this site, so you can put it into the QBCC register yourself and see the licence class and standing before you let us or anyone else start.

Do that with every quote you get. It’s a two-minute check that tells you whether the person pricing your wall is entitled to build it.

What it costs

Height is the biggest lever. The load on a wall climbs faster than its height does, so a 1.8 m wall costs considerably more per metre than a 900 mm one — heavier footings, stronger posts or reinforcement, and engineering that a low wall may not need at all.

After that: length, the material you choose, how hard the site is to get machinery into, what the excavation turns up, and how much drainage the wall needs. Access is the one that surprises people — a wall a truck can reach is a different job from the same wall down the back of a steep block.

We quote in writing after seeing the site, with the wall type, height and drainage spelled out. If you’re comparing quotes, compare what’s behind the wall as well as the face. A cheap price usually means the drainage and backfill have been thinned out, and that’s the part you can’t fix later without pulling the wall down.

Water is the thing that decides how long a wall lasts here. The Bureau of Meteorology’s records for the Mary River show a long flood history with detailed records back to 1910 — significant floods in 1893, 1898, 1955, 1974, 1992, 1999, 2013 and 2022, and the February 2022 peak of 22.96 m was the second-highest ever recorded, behind only 25.45 m in February 1893.

For your wall, that means drainage isn’t an upgrade. Saturated ground is heavier and pushes harder, and a wall with nowhere to send that water is a wall carrying a load it was never designed for. So we build assuming the heavy rain arrives — aggregate and drainage line behind the face, and an outlet that actually goes somewhere — rather than treating it as an optional line on the quote.

Getting started

Get in touch and we’ll arrange a site visit. It helps to know roughly how long the wall needs to be, how much height you’re trying to hold, and what you want the space for afterwards — but if you don’t know, that’s what the visit is for.

You’ll get a written quote setting out the wall, the drainage and whether engineering or approval applies. Check our QBCC licence, 15489031, on the register while you’re comparing — it’s in the footer of this page.

Common questions

How do I check you’re licensed before I book anything?

Our QBCC licence number is 15489031, published in the footer of every page on this site. Put it into the QBCC register and you’ll see the licence and its standing. It’s the check to run on every builder quoting your wall, not just us.

Why does drainage matter so much on a retaining wall here?

Because this area gets serious water. The Bureau of Meteorology has detailed Mary River flood records back to 1910, with major floods in 1893, 1898, 1955, 1974, 1992, 1999, 2013 and 2022 — the 2022 peak of 22.96 m was the second-highest on record. Saturated soil is heavier and pushes harder against a wall, so the drainage and backfill behind the face are what keep it standing.

Can you quote my wall over the phone?

Not accurately. Height, soil, fall, access and where water currently runs all change the price, and those need to be seen. We’ll come out, look at the site, and give you a written quote that spells out the wall type, height and drainage.

What makes one quote cheaper than another for the same wall?

Usually what’s behind the face. Footings, compacted backfill, drainage aggregate and the outlet are invisible once the job’s done, and they’re the easiest things to thin out to win a price. Compare those line by line — they’re also the only parts you can’t fix later without taking the wall down.
