Cheltenham blocks can mix sandy coastal soils with reactive clay pockets and variable drainage—small base-stage mistakes can turn into slab movement, dampness and costly rectification after the pour.

Our comprehensive service includes everything you need to make an informed decision about your property.
We confirm the slab set-out aligns with the plan intent on site, including practical checks around edges and step-downs/step-ups. On tighter Cheltenham lots, small set-out errors can affect boundary clearances, drainage falls and garage/alfresco transitions.
We assess whether the base material looks suitable and evenly prepared for the slab, looking for soft spots, uneven levels and signs of poor trimming. A well-prepared base helps reduce differential settlement that can lead to cracking and door misalignment later.
We inspect formwork straightness, stability and whether edge beams appear correctly formed for the design. If formwork shifts or bows during the pour, slab dimensions and edge support can be compromised, creating ongoing finishing and waterproofing issues.
We check the reinforcement layout is consistent with typical design intent and that steel is properly supported, tied and positioned so it’s not sitting on the ground or drifting during the pour. Correct cover and placement are critical for slab performance and durability.
We verify the membrane is present, lapped and taped where required, and that penetrations are sealed as well as practicable before concrete. In bayside conditions, preventing ground moisture migration helps protect future flooring, skirtings and indoor air quality.
We review the placement and protection of plumbing/electrical penetrations through the slab area, including whether they’re positioned to minimise future cutting or patching. Good coordination at this stage reduces the risk of weakened sections and post-pour rework.

Book it once formwork, reinforcement and the vapour membrane are installed, but before any concrete is poured. In Cheltenham builds, trades can move quickly between plumbing rough-in and the pour, so it’s best to schedule as soon as you get a pour date. That timing allows your builder to rectify issues without delaying the slab unnecessarily.
Knock-down rebuild sites often involve cut-and-fill, reworked levels and removal of old services. That can create uneven base preparation, soft spots, or tricky slab edge conditions near boundaries. We focus on whether the base looks consistent, whether formwork is stable, and whether membranes and penetrations are properly detailed so the slab isn’t relying on patch fixes after the pour.
This inspection focuses on what is physically in place immediately prior to the pour—site prep, formwork, reinforcement placement, membrane continuity and penetrations. We are not redesigning the slab, but we do flag visible inconsistencies, workmanship concerns and installation risks that can affect performance. The report is written so your builder can act on specific, observable items straight away.
Yes. Moisture issues often start at the base stage, particularly if the vapour membrane has gaps, poor laps, or unsealed penetrations. On flatter Cheltenham sites where water can sit after rain, membrane continuity becomes even more important. We document the membrane condition and slab-edge preparation so you can request repairs before concrete covers the problem areas.
You’ll receive a detailed written report with clear photos and actionable recommendations focused on pre-pour readiness. We identify what needs attention, why it matters, and where it is on the slab area so it’s easy to communicate to your site supervisor. The report is designed to support practical rectification before the pour, not vague commentary.
