Mentone’s bayside blocks often deal with wind-driven rain, variable sandy fill and tight side access on knockdown-rebuild sites—small base-stage mistakes can turn into slab moisture and drainage headaches after the concrete is down.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess whether the slab base appears appropriately prepared for the pour, including general trim levels, fill placement and any visible signs of soft spots, ponding or uneven subgrade. This matters because poor base prep can contribute to slab movement, cracking and uneven floors that are expensive to rectify after handover.
We check formwork lines, levels and stability, including edge beam dimensions where accessible, to help confirm the slab footprint matches the intended layout. On Mentone blocks with tight side setbacks, even small set-out mistakes can create boundary issues and complicate cladding, fencing and stormwater runs later.
We inspect visible reinforcement for placement, laps and support (chairs/spacers) so steel is more likely to sit at the correct height within the concrete. If mesh is resting on the ground or poorly supported, it may not perform as designed and can reduce the slab’s ability to handle movement and load.
We look for correct installation of the vapour barrier, including overlaps, tears, penetrations and taping where applicable, before it’s covered by concrete. In a bayside suburb like Mentone, good moisture control at this stage helps reduce rising damp risk and protects floor finishes and indoor air quality long-term.
We review visible plumbing and service penetrations through the base for positioning, spacing from beams and practical sealing readiness. Penetration errors can lead to leaks, concrete cracking around pipes, and difficult repairs once the slab cures—particularly where bathrooms and laundries are set over edge beams.
We check for visible cues that the site is set up to move water away from the slab, such as general falls away from the building line and readiness for stormwater connections (where observable). Mentone’s heavy rain events can expose weaknesses early, so getting water management right before the pour helps avoid future ponding against the slab edge.

Book it for the window after formwork, reinforcement, vapour barrier and services are installed, and before the concrete truck is scheduled to pour. In Mentone, weather can change quickly and sites can be tight, so aim to confirm a time with your builder as soon as the base stage is planned. We’ll inspect what’s visible and document items that should be rectified prior to the pour.
Pre-slab is your best chance to correct issues like poorly supported mesh, missing laps, damaged vapour barriers, misplaced service penetrations, and formwork movement or incorrect dimensions. Once the slab is poured, these become hidden and typically require expensive engineering advice, invasive cutting, or living with the defect. A Stage 1 check is about preventing permanent, locked-in problems.
We assess workmanship and visible compliance items at the base stage, and we reference available drawings and documentation supplied on the day (such as engineering plans) to identify mismatches where they can be observed. Some items may be concealed or only verifiable through documentation, so we report clearly on what was sighted, what wasn’t accessible, and what should be clarified with the builder or engineer before the pour.
Yes. Mentone’s proximity to the bay means moisture and drainage detailing becomes more important, especially for vapour barrier integrity and managing water away from the slab edge. Knockdown-rebuild sites can also include variable fill, older services and confined access, which increases the chance of rushed penetration placement or compromised membrane detailing. A pre-slab inspection focuses on catching these practical issues before concrete makes them permanent.
You’ll receive a detailed report tailored to the Stage 1 – Pre-Slab (Base Stage) Inspection, including photos, descriptions of observed issues, and straightforward recommendations you can pass to your builder. The report is written so you can prioritise what needs attention before the pour versus items to monitor later. If anything is time-critical, we’ll flag it clearly so it’s acted on immediately.
