Batman’s Hill builds often run tight to boundaries with basement and podium-style slabs—small set-out or reinforcement mistakes can be locked in once concrete is poured.

Our comprehensive service includes everything you need to make an informed decision about your property.
We review the slab footprint, rebates, set-downs and critical dimensions that affect walls, door openings and garages/basements. In Batman’s Hill, tight site layouts leave little tolerance for errors, so confirming edge form alignment and levels before the pour helps prevent costly framing and fit-off problems later.
We inspect formwork condition, bracing, boxing around step-downs, and whether the pour area is clean and ready. Poorly supported or poorly sealed formwork can lead to blow-outs, honeycombing and uneven slab edges—issues that are hard to rectify once concrete has cured.
We check mesh and bar size (where visible), spacing, lap lengths, bar chairs, and whether steel has appropriate cover from the ground and formwork. Incorrect cover or missing support can leave steel too close to the surface or sitting in the soil, increasing cracking and durability risks.
We verify the positioning of plumbing penetrations, floor wastes, conduits and any cast-in elements against the plan and practical build requirements. Misplaced penetrations often trigger on-the-spot cutting, patching or redesign, which can weaken the slab and complicate waterproofing.
We assess the vapour barrier for tears, punctures, overlaps, taping at joints, and how it’s treated around penetrations and edges. In inner-city builds like Batman’s Hill where slabs may sit over fill or below-grade areas, membrane continuity is critical to reduce moisture vapour movement into flooring systems.
We look at base material placement, visible compaction concerns, levelness, and whether the site is set up to manage water away from the slab area. Standing water, soft spots or poor falls can compromise the base and contribute to settlement and cracking over time.

Book it for the window after the steel, formwork, penetrations and vapour barrier are installed but before concrete arrives on site. In Batman’s Hill, pours can be scheduled tightly due to site access and pump availability, so aim to confirm a time as soon as you receive the pour date. If anything needs adjustment, there’s still time to fix it without jackhammering cured concrete.
It focuses on what will be hidden forever once the slab is poured: site preparation, slab set-out, formwork condition, steel reinforcement placement and support, penetrations, and the moisture/vapour barrier. We document what’s installed on the day, flag items that may not meet requirements or plans, and provide actionable recommendations so your builder can address issues before the pour proceeds.
Yes. Batman’s Hill projects often include basement areas, podium decks or complex ground-floor slabs with multiple set-downs and service penetrations. We tailor the inspection to what’s accessible at base stage, paying close attention to edge formwork, reinforcement detailing around openings, and how the vapour barrier is terminated and sealed. If parts are not visible on the day, we’ll note limitations clearly in the report.
They can be, particularly where slabs sit over fill, near retaining structures, or adjacent to hardscape and basement walls that influence water movement. A torn or poorly lapped membrane and poorly managed water at base stage can lead to moisture vapour issues later, affecting flooring adhesives, timber movement and mould risk. That’s why we focus on membrane continuity, penetrations sealing, and general base readiness before the pour.
You receive a detailed written report with photos, observations and practical recommendations targeted to the base-stage items we can see before the pour. The report is designed to be easy to share with your builder or site supervisor, with clear descriptions of what needs attention and why. If you want, we can talk you through the key items so you know what to prioritise before concrete is placed.
