Belgrave South blocks often sit on sloping, rain-exposed sites near the Dandenong Ranges—small errors in cut-and-fill, drainage falls or vapour barriers can become big slab and moisture problems after the pour.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess whether the slab platform appears properly prepared for the site’s slope, including fill placement and levels where visible. Poorly prepared base material can settle after the pour, contributing to cracking, uneven floors and doors that don’t close cleanly.
We check boxing lines, dimensions, rebates and step-downs (where accessible) so the slab edge is formed as intended. Errors at this stage can affect wall alignment, brickwork clearances, garage thresholds and external falls once the home is framed.
We look at mesh and trench steel placement, laps and tie-downs, plus whether bar chairs/supports are used to help maintain cover. Reinforcement sitting too low, poorly lapped or inconsistently supported reduces the slab’s ability to handle movement and loads.
We check the membrane for punctures, adequate laps and taping where present, and whether it is turned up at edges where required. In wet conditions common around Belgrave South, breaks or poor laps can allow moisture migration and affect flooring and internal humidity.
We inspect plumbing and service penetrations through the slab area for placement, clearances and sealing detail visible at the time. Mislocated penetrations can force on-the-spot changes during the pour and create weak points or future leak paths.
We review visible provisions that influence how water will move away from the slab area, such as temporary spoon drains, edge conditions and falls around the pad. On sloping Belgrave South sites, controlling runoff before and after the pour helps prevent water pooling under or against the slab.

Book once the site has been prepared and you can see the formwork/boxing, reinforcement and vapour barrier in place, but before concrete is poured. In Belgrave South, wet weather can compress timelines, so try to schedule 24–48 hours ahead. If rain is forecast, it’s still worth inspecting—water pooling or softened base material can be a useful warning sign.
Sloping sites often involve cut-and-fill and retained edges, which can be sensitive to water and compaction quality. A pre-slab inspection focuses on the prepared platform, boxing accuracy, and whether drainage cues suggest water will be directed away from the slab zone. We also pay close attention to reinforcement positioning because uneven support can occur where levels change across the pad.
Yes. We check the membrane for obvious punctures, correct overlaps and general continuity at edges and around penetrations. Once the slab is poured, the vapour barrier is hidden, but it plays a big role in limiting ground moisture entering the home. That matters for flooring performance and indoor comfort, especially on rain-exposed sites around Belgrave South.
They can be. Bush-adjacent sites may have more leaf litter and organic material that needs to be cleared from the pad area, and they often deal with stronger runoff patterns during storms. During the pre-slab inspection we look for signs that the base is clean and stable and that temporary water management around the slab area is sensible, because uncontrolled runoff can undermine the prepared platform.
You’ll receive a detailed written report with annotated photos, identifying items that appear non-compliant or at risk, along with practical recommendations to raise with your builder before concrete is poured. The report is designed to be easy to action: it highlights what to fix, why it matters for the slab’s performance, and which areas should be rechecked prior to the pour.
