Noble Park blocks often combine reactive clay soils, tight site access and infill builds—small base-stage mistakes can lead to slab movement, drainage issues and costly rework after the pour.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess whether the base is properly prepared, compacted and free of soft spots, loose fill and organic material. This matters because uneven bearing can contribute to slab settlement and cracking after the home is built and loaded.
We review formwork alignment, slab dimensions, step-downs and edge beam shape where visible. Accurate formwork helps ensure the slab matches the plans, supports walls correctly, and avoids future issues like out-of-square rooms or misaligned frames.
We check mesh and bar placement, laps, clear cover, and that reinforcement is properly supported on chairs/spacers rather than sitting on the ground. Correct steel positioning is critical to slab strength and to minimise cracking and movement.
We inspect the vapour barrier for tears, gaps, adequate overlaps and sealing around penetrations. A continuous membrane helps reduce rising damp and moisture vapour entering the slab, which can affect flooring adhesives and internal finishes later.
We check that plumbing/electrical penetrations are correctly located, supported and sealed, and that slab edge details are prepared where required. Fixing misplaced or poorly sealed penetrations is far cheaper before concrete is poured.
We look at visible falls and water management around the slab area so water is less likely to pond against the future slab edge. In Noble Park’s winter conditions, poor pre-pour drainage can delay works and increase the risk of moisture-related issues.

Book the inspection once formwork, steel reinforcement, vapour barrier and service penetrations are in place, but before any concrete is poured. In Noble Park, weather can change quickly, so it’s smart to organise the inspection as soon as the pour date is pencilled in. That timing gives your builder a realistic window to fix issues without delaying the build.
Common findings include reinforcement sitting too low or missing chairs, inadequate laps in mesh, torn or poorly lapped vapour barriers, and penetrations that aren’t sealed or supported. We also see formwork alignment issues that affect slab dimensions and step-downs. Catching these items before the pour helps prevent structural, moisture and fit-out complications later in the project.
Yes. We inspect visible elements against relevant requirements and good building practice, and we compare what we can see on site to the documentation available (such as slab drawings and engineering details). If something appears inconsistent—like reinforcement layout or edge detailing—we document it clearly with photos and explain the likely impact, so you can request confirmation or rectification from the builder.
Often, yes. Noble Park includes older sites being re-levelled for new builds and subdivided lots where natural drainage paths may have changed. If water can pond around the slab footprint before and after the pour, it increases moisture pressure and can affect slab edges and finishes. We pay close attention to visible site falls, membrane integrity and sealing around penetrations to reduce avoidable moisture issues.
You’ll receive a detailed written report with clear photos and prioritised recommendations specific to the pre-slab stage. We identify items that should be rectified before the pour, along with the reason they matter and what to ask your builder to address. The report is designed to be easy to share with your site supervisor so decisions can be made quickly.
