Narre Warren North blocks often have fall and reactive clay soils, so set-out, drainage falls, moisture barriers and steel placement need to be right before concrete goes down—fixing it after the pour is expensive.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check the slab platform preparation for signs of inadequate compaction, soft spots, over-excavation or uncontrolled fill. On Narre Warren North blocks with slope, these issues can show up at transitions between cut and fill and may affect slab performance if not corrected before the pour.
We assess formwork for straightness, bracing and correct set-out against the building footprint where visible. Accurate formwork levels and slab edge detailing are essential for correct finished floor heights, door clearances and drainage outcomes around the home.
We inspect reinforcement size and layout where accessible, including laps, tying, trench mesh placement and whether steel is properly supported so it won’t sink into the base during the pour. Correct cover and placement helps the slab perform as designed and reduces cracking risk.
We check the membrane for punctures, inadequate lapping, poor taping and damage from foot traffic, bar chairs or site debris. A continuous vapour barrier is key to limiting ground moisture migration into the slab, which can later affect flooring and indoor humidity.
We review service penetrations (plumbing, conduits) for appropriate clearances and sealing potential, plus slab edge step-downs and rebates where visible. These areas are common leak and termite entry pathways if detailing is left loose at the base stage.
We look for issues that can trap water against the slab area, such as low points, blocked temporary drainage paths and inadequate fall away from the platform. On larger Narre Warren North sites, managing run-off early helps prevent moisture problems and base softening before concrete is placed.

Book it once the site has been prepared, formwork is up, steel is tied and the vapour barrier is laid, but before any concrete is poured. In Narre Warren North, weather can change quickly and sloping blocks can soften after rain, so aim for the day before the scheduled pour if possible. That timing gives your builder enough room to rectify issues without pushing the slab date.
If you have them, provide the slab and footing engineering drawings, site plan, drainage plan, and any soil test or classification information. These documents help us understand what reinforcement and detailing are expected for your build and what finished levels should achieve. Even if you don’t have every document on hand, we can still inspect what’s visible and report on workmanship and obvious non-compliances.
Yes, if your build uses waffle pods we inspect the setup that’s visible at the time, including pod layout consistency, edge formwork, reinforcement placement, membrane continuity and penetrations. The goal is to confirm the system appears installed in line with the engineering intent before concrete hides the critical details. Any concerns are documented with photos and clear rectification notes for your builder.
They can be. Sloping sites often involve cut-and-fill, step-downs and more opportunities for water to flow toward the slab platform if temporary drainage isn’t managed. That can affect base stability, membrane integrity and edge detailing before the pour. A Stage 1 inspection focuses on those “before it’s buried” items so you can request corrections while access is easy and fixes are straightforward.
We look for visible slab-edge and penetration details that relate to termite management and note where the installation should be confirmed against your chosen system and requirements. Some termite measures are installed at or after the pour, so the Stage 1 inspection can’t verify every component is complete. It does help by identifying gaps, exposed pathways or messy penetrations that can undermine later termite protection if left unaddressed.
