Hawthorn East builds often sit on tight inner-suburban blocks with fill, drainage constraints and close boundaries—getting the base stage right helps avoid slab moisture issues, uneven support and costly rectification once concrete is down.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess the prepared base for uniformity, visible soft spots, grading and readiness for concrete placement. A consistent base helps reduce the risk of slab settlement and cracking that can show up later as uneven floors or sticking doors.
We check formwork placement, straightness and practical level/step transitions that affect slab thickness and edge performance. Errors here can lead to out-of-spec slab dimensions, poor edge support and follow-on issues with brickwork alignment.
We inspect visible reinforcement layout, laps, tying and bar/mesh support (chairs/spacers) so steel sits at the intended height within the slab. If reinforcement is incorrectly placed or inadequately supported, it can reduce the slab’s ability to handle loads and movement.
We check the membrane for punctures, tears, laps and taping, plus how it’s turned up at edges and penetrations. A continuous barrier helps limit ground moisture migration that can contribute to dampness, adhesive failures and flooring problems.
We review visible slab penetrations for plumbing and other services, looking for correct positioning, clearance and sealing approach. Misplaced penetrations can trigger expensive cutting, patching or structural compromises after the pour.
We look for ponding, water paths and practical management of stormwater around the slab area. Standing water and poorly controlled runoff can undermine base preparation and increase the chance of moisture-related issues under the slab.

Book it for the window after formwork, reinforcement and the moisture membrane are installed, but before concrete is poured. In Hawthorn East, schedules can move quickly once the site is ready, so it’s best to line up the inspection as soon as you get the pour date. That timing ensures we can actually see and document the key elements that will be hidden after the pour.
Most homeowners can’t confidently assess reinforcement laps and placement, membrane continuity at edges and penetrations, or whether formwork and slab edge detailing look consistent with the build intent. We focus on what’s visible at that stage, photograph it, and translate it into clear, actionable items you can take to your builder. It’s about catching practical construction risks before they’re buried.
We look at both. The inspection notes visible compliance-related concerns (such as membrane lapping and reinforcement support) and workmanship items that commonly cause defects later. Because we’re assessing what’s accessible before the pour, the report is geared toward immediate corrective action. If something can’t be confirmed visually at the time, we’ll state that clearly so you know what’s verified and what isn’t.
Yes. Hawthorn East has plenty of knock-down rebuilds and extensions on established lots, and those sites can have variable fill, older drainage paths and tight boundaries that make set-out and water management more sensitive. At pre-slab stage, small errors—like membrane damage at penetrations or poor water control around the base—can turn into moisture and movement issues that are difficult to pinpoint once the slab is poured.
We document the issue with photos, explain why it matters, and outline practical recommendations so you can request rectification from the builder before the pour proceeds. Because it’s the base stage, many fixes are straightforward—repositioning reinforcement supports, repairing membrane tears, or correcting formwork details—compared with cutting and patching concrete later. Your builder remains responsible for implementing any changes.
