Wheelers Hill blocks often sit on reactive clay and sloping sites near drainage lines—small base-stage errors can lead to slab movement, moisture ingress and costly rectification after the pour.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check the base is properly trimmed, compacted and consistent, with attention to soft spots, uneven fill and edge preparation. In Wheelers Hill cut-and-fill sites, poor base preparation can translate into differential settlement and slab cracking after the first full wet season.
We inspect formwork alignment, bracing and dimensions against the drawings, including edge beam widths, step-downs and rebates for garage entries or alfresco areas. Accurate formwork helps avoid out-of-square slabs and costly rework to brickwork, frames and cladding later.
We verify reinforcement size and layout, lap lengths where visible, and that mesh and bars are properly supported on chairs to achieve cover. Steel sitting too low or touching the ground reduces performance and increases the risk of cracking and corrosion within the slab.
We check the membrane is correctly lapped, taped where required, and extended to edges without tears, punctures or gaps around penetrations. This is a key control for moisture vapour that can contribute to damp odours, floor coverings failure and mould-friendly conditions.
We review the location and sealing of penetrations, including pipe sleeves and areas where the membrane has been cut. Misplaced services can force on-site compromises, while poorly detailed penetrations can become pathways for moisture and pests after handover.
We look at visible drainage provisions and whether the slab edge and surrounding ground levels appear to support water shedding away from the build. On Wheelers Hill blocks with fall, early drainage decisions influence how stormwater behaves during construction and once landscaping is complete.

Find answers to the most frequently asked questions about our inspection service.
Book once the site has been prepared and you can see the formwork, reinforcement and moisture barrier in place, but before any concrete is poured. In Wheelers Hill builds, this window can be short, especially on busy estates or knock-down rebuilds. Contact ACE as soon as the base stage is scheduled so we can inspect at the correct point and you can action any items before the pour.
Engineering slab drawings, the site plan, and any soil test/classification information are the most useful. They allow us to compare what’s installed on site to what’s specified for your build, including reinforcement layout, slab thickenings and step-down areas. If you only have a builder’s plan set, we can still inspect workmanship and visible detailing, but the engineer’s details make the findings more targeted.
It shouldn’t, as long as it’s booked early and coordinated with your site supervisor. The goal is to identify issues while there’s still time to rectify them without rushing decisions. If we find concerns that need clarification, our report helps you raise specific questions quickly. It’s far cheaper to adjust reinforcement, membranes or formwork now than to pursue fixes after the slab has cured.
They can be, because sloping sites often involve cut-and-fill, stepped formwork and more complex edge detailing. Those elements increase the chance of uneven sub-base, incorrect step-downs or drainage that directs water back toward the slab edge. A Stage 1 inspection in Wheelers Hill focuses on these practical risks by checking preparation, set-out and membrane continuity before they’re hidden under concrete.
Yes—while Stage 1 is primarily about the slab base, we can note visible factors that affect termite management at this point, such as slab penetrations, membrane detailing and whether the slab edge exposure appears suitable for inspection zones where applicable. Termite protection systems are often installed around this stage, so it’s a good time to confirm the build is set up to support the intended protection and future inspections.
