Why a retaining wall

Turn a tricky block into usable yard

A retaining wall does more than hold back dirt. Here is what our customers get out of one.

Level out a sloping block

A wall carves a flat, level area out of a slope, so you finally have somewhere the ground isn't running away from you.

Make the yard usable again

Turn a steep, awkward corner into a spot the kids can play, you can entertain, or you can put a shed or trampoline.

Tidy up garden beds and edges

Square off your garden beds and lawn with a clean edge, so the whole yard looks sorted instead of messy.

Pair a wall with a new fence

Building both at once? We put the fence straight on top of the wall so the levels line up and it looks like one job.

Help with drainage and erosion

A wall done right sends water where it should go and stops the soil washing away every time it buckets down.

Add value to the place

Usable, tidy outdoor space is a real selling point, and a solid wall tells buyers the place has been looked after.

Your options

The right wall for your block

There is more than one way to build a retaining wall, and the best pick comes down to your block, the height you need and the look you are after. Here is what we do, and we will talk you through it all when we measure up.

Timber sleeper walls

A warm, natural look that suits most backyards. Treated timber sleepers are a solid, good-value choice for the everyday retaining job.

Concrete sleeper walls

Tough and long-lasting, and the go-to for taller walls or wetter spots. They handle the years and the weather without fuss.

Retaining wall and fence combos

Need both? We build the wall and set the fence straight on top in the one go, so the levels line up and you save a second visit.

Heights to suit your block

From a low garden edge to a taller wall that levels a real slope. If it needs engineering, we sort that out and let you know when we quote.

Drainage done properly

The right backfill and an ag line behind the wall, so water has somewhere to go instead of building up and pushing on it.

How it works

Simple, and no surprises

  1. Free measure-up

    We come out, look at the block, talk through timber or concrete and the height you need, and answer your questions. No charge and no pressure.

  2. A clear quote

    We give you a straight-up price and honest advice on what will work best for your block, backed by quality workmanship.

  3. Our own crew builds it

    The same team that quotes does the job. No subbies, so nothing gets lost in translation and the drainage gets done right.

  4. Cleaned up and done

    We cart away the spoil and leave your yard tidy, the way we would want ours left.

Questions

Retaining wall FAQs

Timber or concrete sleepers?

Both do the job, so it comes down to the look you want and the block. Timber sleepers give a warm, natural feel and suit most backyards. Concrete sleepers last longer and handle taller walls and wetter spots. We will talk you through both when we come and measure up.

How high can a retaining wall go?

A wall over 1 metre usually needs engineering and certification. We will sort that out and let you know when we quote, so there are no surprises down the track.

Can you build a retaining wall and fence together?

Yes, and it is a common ask. We build the wall and put the fence straight on top in the one go, so the levels line up and it looks like it was always meant to be there. Doing both together saves you a second visit too.

What about drainage?

We do drainage properly behind the wall with the right backfill and an ag line, so water has somewhere to go instead of building up and pushing on the wall. It is the part you never see, and it is the part that keeps the wall standing.

Do you handle sloping blocks?

Yes, sloping blocks are a lot of what we do. A retaining wall is how you turn a slope into a flat, usable space, whether that is levelling a spot for the kids to play or squaring up a garden bed.

How much does a retaining wall cost?

Every block is different, so we come out and give you a price after a free measure-up. It comes down to the length, the height, the material, and how much digging and drainage the job needs. There is no obligation to go ahead.
