Clayton’s knock-down rebuilds and tight townhouse sites leave little room for base-stage mistakes—one missed vapour barrier lap or poorly supported trench mesh can be locked in under concrete for decades.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check the slab set-out against the visible set-downs, step-downs and edge forms, including whether forms look straight, stable and appropriately braced. This matters in Clayton where boundary-clearance builds are common—any formwork movement can change slab dimensions and create flow-on issues for frames, cladding and drainage falls.
We visually assess the prepared base for soft spots, uncontrolled fill, ponding water and uneven bedding that can telegraph into the slab. Where the base looks inconsistent, we flag it early so your builder can address it before reinforcement and concrete hide the problem.
We inspect the membrane for tears, punctures, inadequate laps, poor taping and gaps around penetrations and edges. Clayton’s mix of older sites and redeveloped blocks can mean disturbed ground and services that make membranes easy to damage—continuity is key to reducing rising moisture into flooring and finishes.
We check that trench mesh/rebar and slab mesh appear consistent with the installation intent, and that steel is positioned with appropriate support (chairs/bar supports) rather than sitting on the ground. Correct support helps the steel perform as designed once the concrete is placed.
We review visible plumbing and other service penetrations for placement, sleeving/clearances where evident, and whether penetrations compromise the membrane or reinforcement layout. This helps prevent later conflicts such as cutting reinforcement or chasing pipes after the slab has cured.
We compile a practical pre-pour punch list with photos, highlighting items to discuss with your builder immediately (for example, membrane repairs, missing supports, or unclear detailing at edges and rebates). The report is written so you can forward it directly to the site supervisor for action.

Book it for the window after the base is prepared and the reinforcement and membrane are installed, but before any concrete is poured. In Clayton, builders often schedule pours quickly once inspections and trades are lined up, so aim to book as soon as you receive a likely pour date. We’ll attend on site and provide a report you can act on immediately.
A Stage 1 inspection focuses on what will be locked under the slab: site preparation, formwork, moisture/vapour barrier installation, steel reinforcement placement and visible service penetrations. We also note workmanship concerns that can affect slab performance, such as membrane damage, missing steel supports or questionable edge detailing. Anything we can’t verify visually is flagged for confirmation with your builder.
We can review any documents you provide and comment on whether site conditions observed appear consistent with the intended build stage, but a visual inspection is not a substitute for geotechnical testing or formal compaction testing. If the base looks uneven, wet, disturbed or inconsistent, we’ll recommend you request the relevant testing evidence or clarification from the builder before proceeding with the pour.
They can be. Clayton often sees tight-access builds with boundary walls and shared driveways, which can make excavation, spoil removal and base preparation more constrained. That increases the importance of checking slab set-out, edge forms, drainage falls and membrane continuity—especially where services run close to boundaries. A pre-slab inspection helps identify issues early, before concrete makes changes difficult.
On redeveloped Clayton sites, pay close attention to disturbed ground, old service trenches, and how new stormwater and sewer connections are handled at the slab edge. These areas can be where membranes get punctured and where base material quality varies. A Stage 1 inspection focuses on these “hidden” risk points and documents repairs or clarifications needed before the pour goes ahead.
