Most homeowners picture the finished retaining wall – the clean block face, the tidy garden bed, the level lawn. But at SMP Buildcrete, we know the real transformation often happens before a single block is laid. A professional retaining wall digout turns steep, wasted ground into flat, usable backyard space you can actually enjoy – room for kids to play, a patio setting, garden beds or simply more breathing room around your home – all of which can add real value to your home.
The photos above tell the story better than any brochure. A steep, overgrown embankment beside the home – dead space that stole usable backyard area. Then the digout: a clean vertical cut, tonnes of earth removed, a mini excavator working in a tight space beside the building without compromising the structure. The result at this stage is raw – but the change is dramatic. Flat ground where there was once a slope. Space where there was once a hazard.
The retaining wall itself comes next. But the backyard you gain? That starts here.
If you are weighing up retaining walls in Ballarat, here are the five pre-work considerations we believe matter most. At SMP, we have decades of experience in clean, managed and reliable retaining wall installations – we take care of all of these considerations for you.
1. Start with the land you want to reclaim
Before choosing wall materials or colours, ask a simpler question: what could you do by pulling the positioning back to reclaim extra flat land?
Steep backyards are common across Ballarat and Western Victoria – especially on sloping blocks where a tall embankment sits metres from the house, leaving a narrow, cluttered strip that is good for little more than storing pots and hoses. Cutting that slope back and levelling the area can reclaim a surprising amount of square metres. That is not just cosmetic. Usable outdoor space is one of the most practical ways to improve how you live in your home – and it can add genuine value when the work is done properly.
The digout sets the footprint for everything that follows. Get the levels, dimensions and access right at this stage and the finished wall supports a backyard you will actually use.
2. Protect foundations and existing structures
This is the consideration that keeps any homeowner up at night (that we at SMP pride ourselves on managing to alleviate this stress for you)
Excavating close to a house, garage or boundary fence is not a DIY weekend job. Dig too aggressively or without a proper assessment and you risk undermining footings, cracking brickwork or shifting soil that supports existing structures. Safe Work Australia is clear: excavation below the level of nearby footings must be assessed by a competent person, with appropriate ground support where the site demands it. SMP prides itself on our ability to protect your investment with our retaining wall services – for a recent example of a tight install with no scope for error check out this recent project – the results speak for themselves.
On tight Ballarat blocks – where a mini excavator might be working within a few metres of your external wall – experience matters. Our experienced local operators plan each cut, manage spoil placement and work methodically so your home stays structurally sound throughout the digout. That peace of mind is worth more than any saving from cutting corners on pre-work.
3. Understand your soil and plan drainage early
Every retaining wall digout reveals what is actually under your lawn: clay, rock, fill, groundwater seepage or a mix of all three. Ballarat’s variable soils mean two neighbouring properties can behave very differently once you start cutting.
Drainage is not an afterthought – it belongs in the pre-work plan. Water building up behind a retaining wall is one of the fastest ways to compromise its long-term stability. Before the wall goes in, we assess how water moves across your block, where it needs to be directed, and what drainage will be built into the finished structure. Getting this right during excavation saves costly remedial work later.
At SMP Buildcrete, we have been installing retaining walls in Ballarat for decades with a range of finishes – from concrete sleepers to besser blocks and always handle the drainage considerations up from which lets you rest assured that our finish will be professional and prevent any drainage headaches down the road.

Where the scope warrants it, we work alongside engineers and geotechnical specialists – part of the end-to-end support that comes with choosing a registered building practitioner rather than a one-off labour hire.
4. Locate underground services before any machine arrives
It sounds obvious. It is also the step most often skipped – with expensive consequences.
Before excavation begins, a Dial Before You Dig enquiry should confirm the location of water, gas, electrical, sewer and telecommunications lines on your property. Even on a residential backyard, services can run closer to the surface than you expect. Striking one mid-digout causes delays, repair costs and genuine safety risks.
At SMP Buildcrete, service location is built into our pre-start checklist. We do not start an excavator until we know what is beneath the ground – and we hand-dig carefully in the zones where services are marked.
5. Permits, machinery and managing the full job
A significant retaining wall digout is not just about moving dirt. Depending on wall height, proximity to boundaries and local requirements, you may need council permits or a building permit through a registered building surveyor. Excavation over certain depths also triggers work health and safety obligations – including safe battering, edge protection and a site-specific approach to how machinery operates near structures.
This is where an end-to-end builder makes the difference. At SMP Buildcrete, we manage the full scope: initial consult and site assessment, permit and approval coordination, skilled excavation with our own plant and operators, and the retaining wall construction that follows. You are not left coordinating an excavator hire, a wall builder and a permit application on your own.
With over 20 years across residential and commercial work in Ballarat, registered builder practitioner (DB-L 100480), we bring the machinery, the paperwork and the craftsmanship under one roof.
