Should I DIY My Shed Slab or Hire a Concreter?
It's a fair question, and a lot of people research how to lay a concrete slab for a shed, how to build a concrete base for a shed, or how to pour a shed foundation themselves — often because they want to understand what the job involves before deciding. This page gives you an honest picture so you can make the right call for your situation.

For a small slab — say a 3m × 3m garden shed — DIY is achievable for someone with some practical experience and the right help. But for anything larger, the work gets serious quickly.
Earthworks and compaction
You'll need to excavate, level and compact the ground to the right depth. Soft, sloped or clay ground makes this harder.
Formwork
Getting the forms level and square takes time and care. Errors here mean an uneven slab.
Ordering and handling concrete
Ready-mix truck concrete is delivered fast and needs to be placed, spread and finished quickly — before it sets. A small crew is essential.
Finishing
Getting a flat, smooth and properly finished surface takes skill. Poor finishing leads to cracking, pooling water and an uneven floor.
Timing and weather
Ballarat weather can be unpredictable. Hot days, cold snaps and wind all affect how concrete cures.
When DIY might make sense
- Small slab (3m × 3m or under)
- You've done concrete work before or have help from someone who has
- The ground is already flat, firm and cleared
- Easy access — no awkward gates or soft ground
- You're comfortable with the physical work and tight timing
When it's worth hiring a concreter
- Anything larger than a small garden shed
- Sloped or uneven ground
- Soft, clay-heavy or poorly drained soil
- Limited access requiring careful planning
- You need a neat, professional finish
- You want it done right the first time
The cost reality check
DIY can save money on labour, but the material costs (concrete, mesh, formwork, hire equipment) add up quickly. If the job doesn't go well, fixing a bad slab is expensive. For most homeowners, getting a quote from us first is the sensible starting point — you might be surprised how the numbers compare.
