Mitcham blocks can include reactive clay and sloping sites near creek lines—small setup errors before the pour can lead to cracking, drainage issues and expensive rectification later.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check the subgrade condition, level transitions and base material placement for signs of soft spots, uneven build-up or poor trimming. A well-prepared base supports the slab uniformly and reduces the risk of differential movement that can later show as cracking or uneven floors.
We inspect boxing alignment, slab thickness allowances, step-downs and edge beams where visible. Correct formwork matters because once poured, slab dimensions, rebates and edge heights affect brickwork clearances, garage falls and how water drains away from the house.
We verify the mesh/rebar layout, laps, tying and whether reinforcement is properly supported to achieve the required concrete cover. Steel sitting too low, too high or with poor laps can reduce slab performance and durability, especially around openings and stress points.
We check the membrane type, overlaps, penetrations and taping to ensure it forms a continuous barrier. Inconsistent vapour barrier installation can allow rising damp and moisture migration, which can affect floor finishes and indoor comfort later.
We review the placement of plumbing penetrations, sleeves and set-downs for wet areas where accessible. Misplaced services often lead to core drilling or patching after the pour, which can compromise waterproofing zones and create avoidable rework.
We look for indicators that surface water will be directed away from the slab edge, including visible level planning and provisional drainage points. Early water management is critical on Mitcham sites where runoff can track toward the building if levels or falls are wrong.

Find answers to the most frequently asked questions about our inspection service.
Book as soon as your builder confirms the slab is ‘ready for pour’—typically after boxing is set, steel is tied, the vapour barrier is down and services are in place. In Mitcham, where weather can change quickly and pours are often scheduled tightly, organising the inspection early helps you avoid a rushed pre-pour window and gives time for any required fixes.
Most issues at this stage are still practical to rectify, including mesh positioning and laps, missing chairs, poor membrane overlaps or unsealed penetrations, and formwork alignment or step-down details. These items are far easier to correct before concrete is placed. Once poured, fixes often involve cutting, grinding or patching, which can add cost and complexity.
Yes. We use the available approved documentation for the build stage to cross-check key items such as slab layout intent, visible edge/step details, and reinforcement placement where accessible. Our focus is on what can be verified onsite before the pour, and we note any discrepancies or missing information that should be clarified with the builder or engineer prior to concreting.
Often, yes. Mitcham blocks can include slopes, cut-and-fill platforms and disturbed ground from knockdown-rebuild work. Those conditions can influence how water moves and how the slab is supported across the site. A pre-slab inspection helps confirm the base is even and stable, edge detailing is appropriate to visible conditions, and the vapour barrier and penetrations are installed to reduce moisture-related issues.
Time varies with slab size and complexity, but most pre-slab inspections are completed efficiently because access is open and defects are visible. You’ll receive a written report with photos identifying observed issues, why they matter and what to ask your builder to rectify before the pour. It’s designed to be easy to forward and use as a pre-pour checklist.
