Slab Inspections in Brisbane
Once the slab has cured and before the frame arrives, a slab inspection confirms the finished concrete matches what was designed and poured. For Brisbane homes, from the north around Everton Park and Bracken Ridge to the bay at Wynnum, our builder-inspectors measure the slab dimensions, check it is square and level, and review edge rebates and step-downs for the wet areas, garage and alfresco. We look over the surface finish for cracking, honeycombing or cold joints, and confirm the brick ledge overhang stays within tolerance so the brickwork sits correctly. Catching a dimensional or set-down error now, while the frame is still off site, avoids flow-on problems with waterproofing falls and door thresholds later in the build.

Why a slab inspection matters in Brisbane
A slab-stage check confirms the pour matched the pre-pour inspection and gives you a documented baseline — set-out errors and edge/step-down problems are far cheaper to raise now than after the frame is standing.
Common slab-stage items in Brisbane include surface cracking and honeycombing, correct wet-area and garage step-downs, overall dimensions and square, level across the slab, and brick overhang kept to around 15mm. On reactive clay sites we note any early shrinkage cracking and whether set-downs give enough fall for later shower and balcony waterproofing.
Local conditions in Brisbane
Brisbane's new-build activity runs from the northern suburbs — Aspley, Bracken Ridge, Carseldine and the Fitzgibbon priority development area — out to the bayside east around Wynnum and Manly West. Much of it sits on reactive clay and some on filled or sloping lots, which makes the early slab and frame stages worth getting right. Our builder-inspectors cover the whole metro area and send a same-day photo report referenced to the NCC, the relevant Australian Standards and the QBCC Standards and Tolerances Guide.
What we check at the slab stage
On the cured slab, before the frame goes up, we check the finished concrete and set-out:
Finished slab
- Surface finish, honeycombing and cold joints
- Edge rebates and step-downs to wet areas/garage
- Plastic shrinkage or structural cracking
Dimensions & penetrations
- Overall dimensions, square and level
- Penetration locations for plumbing and services
- Brick overhang allowance at the slab edge (≤15mm support rule)
Every item is photographed and referenced to the relevant Australian Standard, NCC clause or the QBCC Standards and Tolerances Guide, then delivered in a same-day digital report you can hand straight to your builder.

Other inspection stages across Brisbane
Most owners book several stages so defects are caught before the next trade covers them. Alongside the slab inspection, we also inspect across Brisbane:

Slab Inspection FAQs — Brisbane
What does a slab inspection check after the pour?
We confirm the slab dimensions, square and level, review the surface for cracking or honeycombing, and check step-downs and the brick ledge before the frame goes up.
Is some slab cracking in Brisbane normal?
Fine surface shrinkage cracking can be minor, but we assess width, location and pattern and flag anything that needs an engineer, especially on reactive clay blocks.
Can you inspect the slab before my frame is delivered?
Yes, and that is the ideal time. With the slab clear we can measure and photograph everything before the frame covers the edges and set-downs.
