Burnley builds often deal with tight inner-suburb blocks, neighbouring fences and drainage paths toward the Yarra corridor—small set-out or moisture-barrier mistakes at this stage can become permanent once the slab is poured.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check whether the base is properly prepared for the slab system being used, including surface condition, compaction indicators where visible, and whether the slab platform appears even and consistent. This matters because uneven preparation can contribute to slab thickness variations, cracking risk, and difficulty achieving correct finished floor levels on completion.
We inspect formwork alignment, bracing, and the visible set-out against the intended slab footprint, including step-downs and rebates where applicable. In Burnley’s tighter blocks, small set-out errors can reduce boundary clearances or create clashes with paths and fences, and once poured, correction is disruptive and costly.
We check reinforcement type and placement as visible, including laps, spacing, and whether bars/mesh are adequately supported on chairs to maintain cover. Correct positioning is essential so reinforcement ends up within the slab where it’s designed to work, not sitting too low in the base or too high near the surface.
We assess the membrane for damage, correct laps, taping where required, and tidy detailing around pipes and penetrations. A compromised barrier can allow moisture vapour to migrate into the home, contributing to flooring issues, musty odours, and long-term durability problems—especially if drainage around the block is complex.
We review plumbing and electrical penetrations for position, sealing approach, and whether the layout appears coordinated with the slab and future wet areas. Fixing misplaced penetrations after the pour can mean cutting concrete, patching, and potential waterproofing complications later in bathrooms and laundries.
We look for signs the site will manage water away from the slab edge, including how the base stage interfaces with planned external levels and perimeter detailing. This is important because poor edge moisture control can increase the likelihood of dampness at slab edges and reduce the performance of finishes and framing over time.

Find answers to the most frequently asked questions about our inspection service.
Book it for the window after the base is prepared and formwork, reinforcement, and the moisture/vapour barrier are installed, but before concrete is poured. In Burnley, where sites can be tight and trades move quickly, it helps to schedule as soon as you know the pour date. ACE coordinates timing with you or your site supervisor to avoid missing the pre-pour stage.
Yes. We look for punctures, incomplete laps, poor taping, and weak detailing around penetrations and edges—issues that can happen after foot traffic or during service installation. If damage is visible, we document it with photos and outline what rectification should occur before the pour. Catching these problems pre-slab is far easier than diagnosing moisture-related flooring issues later.
A Stage 1 Pre-Slab Inspection is primarily a visual and compliance-focused check of what is accessible at the time, including site preparation indicators, formwork, steel and membranes. Formal compaction testing usually requires separate geotechnical testing and documentation. If compaction evidence appears unclear on site, we can note the concern and recommend you request the relevant test results or certificates from your builder.
Burnley projects can involve knock-down rebuilds and infill blocks where services have been altered and boundaries are close. That can increase the chance of set-out pressure, penetrations landing in awkward locations, and membrane detailing being rushed around pipes. We also pay attention to how water is intended to move away from the slab edge, particularly on blocks with limited fall or complex drainage paths.
You receive a detailed report with photos, clear descriptions of what was observed, and practical recommendations on what should be addressed before the pour. The report is written so it can be shared directly with your builder or site supervisor to request rectification while the site is still open and accessible. If you want, we can clarify findings so you understand what’s urgent versus minor.
