Malvern builds often sit close to boundaries and mature trees, and many knock-down rebuilds must tie into older services—making pre-slab checks critical before concrete locks everything in.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check the slab area is properly cleared, levelled, and prepared, including areas that are easy to miss on narrow Malvern sites. Good base preparation supports consistent slab thickness and reduces the chance of soft spots and future cracking.
We assess formwork straightness, bracing, and measurements, including set-downs for wet areas, garages, alfresco zones, and steps. Correct formwork ensures the slab matches the approved layout and helps prevent water ponding and trip hazards later.
We inspect reinforcing mesh and bars for correct placement, laps, tie-downs, and support (chairs/bar supports) so steel is positioned to work within the concrete. Poor placement can reduce structural performance and is difficult to verify after the pour.
We check the vapour barrier for continuity, damage, and correct lapping/taping where visible, including around penetrations and edges. In Melbourne conditions, good moisture detailing helps manage damp risk and protects floor finishes over the life of the home.
We verify service penetrations are located sensibly and protected (where visible), so plumbing and electrical rough-ins don’t compromise the slab or end up in the wrong place. This is especially important where Malvern rebuilds must coordinate with existing connections and tight setbacks.
We review visible provisions that affect how water will move away from the slab area, including edge conditions and obvious fall-related risks prior to the pour. Catching drainage-related issues at base stage helps avoid moisture problems and costly rectification once landscaping is complete.

Book it once formwork, reinforcement, moisture barrier (where used), and service penetrations are in place, but before any concrete is poured. In Malvern, tight access and fast pour scheduling can mean short notice, so it’s smart to line up an inspection as soon as you have a likely pour window. ACE will inspect promptly and provide clear items to raise with your builder.
We independently verify key items that are easy to overlook under time pressure—reinforcement position and laps, support chairs, formwork dimensions and set-downs, moisture barrier continuity, and penetrations through the slab area. The goal isn’t to duplicate supervision; it’s to provide a documented, third-party check so issues are identified before they’re hidden under concrete.
It doesn’t have to. The best approach is to schedule the inspection for the day before the pour, or early on pour day before trucks arrive. If we find issues, you can decide whether they’re critical to fix immediately or can be confirmed/rectified quickly. Our report and photos help your builder respond efficiently and keep the program moving.
Yes. Established Malvern blocks often have existing fences, paving, trees, and older service routes that can influence slab set-out and penetration locations. There can also be constraints from boundary proximity and limited working space, which increases the chance of formwork alignment or edge detailing being compromised. A pre-slab inspection helps confirm the base stage matches the approved plan before concrete locks it in.
Yes. ACE Building and Pest Inspections supplies a detailed report with photos and specific, practical recommendations that your builder can follow up before the pour. We focus on what can be verified at Stage 1 and what needs confirmation or adjustment now, so you’re not left with vague notes. This makes the report useful in real site discussions.
