Chinatown builds often involve tight CBD sites, basement slabs and complex drainage interfaces—getting set-out, moisture control and reinforcement right before the pour is critical.

Our comprehensive service includes everything you need to make an informed decision about your property.
We review slab edge forms, rebates, step-downs and visible level markers so the slab is formed to the intended layout. In Chinatown’s tight sites, small set-out errors can create boundary and fit-out issues later, so we focus on the basics that affect the final footprint and internal floor transitions.
We check that formwork appears adequately supported and aligned, including around corners, thickenings and penetrations. Stable formwork helps reduce the risk of blow-outs and uneven slab edges during the pour—problems that are difficult to correct once concrete has cured.
We inspect trench mesh and/or reinforcement bars for placement, laps, tying, and support (chairs/bar supports) to help achieve correct cover. Poorly supported steel can end up too low or too high in the slab, reducing performance and increasing the risk of cracking and long-term durability issues.
We check the vapour barrier for tears, punctures, adequate overlaps and taping, plus detailing at edges and around penetrations where visible. This is particularly important where ground moisture management is critical to protect floor coverings, reduce mould risk, and support the slab’s long-term condition.
We review the positioning of visible plumbing/electrical penetrations, sleeves and set-downs so services are where they should be before concrete is poured. In Chinatown builds with limited access after the pour, getting penetrations right can prevent core drilling, patching and waterproofing headaches.
We visually assess site cleanliness, sub-base readiness and any visible provisions for managing water around the slab area. Where drainage interfaces are part of the base stage, we note concerns that could contribute to water tracking under the slab or into adjoining areas.

Book once formwork, reinforcement, vapour barrier and penetrations are installed, but before concrete is poured. In Chinatown, timing can be tight due to restricted site access and scheduled concrete deliveries, so it’s best to line up the inspection as soon as you have a likely pour date. We’ll tell you what needs to be ready so the visit is efficient and useful.
Yes. Many Chinatown sites have narrow access ways, shared laneways or staged construction areas. We focus on what can be verified visually at the base stage: reinforcement placement/support, vapour barrier laps and penetrations, formwork stability and slab edge preparation. If any areas are obstructed at the time, we document limitations clearly and advise what access or photos are needed to confirm key items.
Typical issues include torn or poorly lapped vapour barriers, reinforcement not adequately supported on chairs, insufficient lap lengths, and penetrations that are offset from plans or too close to slab edges. We also see messy sub-base conditions that can puncture membranes during the pour. The goal is to catch these problems early so the builder can correct them before concrete locks everything in.
They can. Basement or podium-style slab areas often include more penetrations, set-downs, and interfaces where water management is critical. During a Chinatown Stage 1 inspection, we pay close attention to membrane detailing, formwork around thickenings and set-downs, and coordination of sleeves/penetrations that may be difficult to alter later. We also highlight any areas where additional waterproofing or engineer confirmation may be needed.
Yes. You’ll receive a detailed report with photos, clear descriptions of each issue, and practical recommendations you can forward to the builder or site supervisor immediately. Because this is a “before concrete” stage, the report focuses on actionable items that can be corrected quickly—such as re-taping membrane laps, repositioning reinforcement supports, or adjusting penetrations—so the pour can proceed with fewer risks.
