Glenferrie builds often sit on tight inner-suburban blocks with shared boundaries, established trees and variable ground conditions—getting the base stage right helps prevent costly slab movement, damp issues and boundary-related defects.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check that the base is properly prepared for the slab—clearing, levelling, compaction and any visible soft spots—because poor preparation can lead to differential settlement and cracking once the slab is loaded.
We verify slab boundaries, step-downs, rebates, penetrations and edge thickening locations against what’s visible on site. On Glenferrie blocks close to boundaries, correct formwork helps avoid encroachments, uneven slab edges and problems fitting frames and claddings later.
We inspect mesh and bars for placement, lapping, tying and support chairs/spacers so steel sits at the correct height within the concrete. Correct reinforcement placement improves slab performance and reduces the risk of cracking and edge lift.
We check the vapour barrier for adequate coverage, overlap, taping and damage (tears or punctures) before the pour. This is critical for controlling rising damp and reducing moisture-related flooring problems once the home is finished.
We review plumbing and conduit penetrations for location and sealing approach, and whether they appear appropriately sleeved/protected before the pour. Errors here can cause slab cutting later, leaks under the slab or difficult fit-offs.
We look for areas where water may pond near the slab edge and note whether the ground profile and site works support drainage away from the building footprint. Managing moisture around the slab is a key factor in reducing movement in reactive soils.

Book once formwork is complete and reinforcement, moisture barrier and service penetrations are installed, but before any concrete is poured. In Glenferrie, access can be tight and trades may work quickly, so it’s best to schedule as soon as the builder confirms the pre-pour date. That way, any changes—like mesh support, barrier repairs or set-out adjustments—can be completed without delaying the pour.
We assess factors at the base stage that influence how moisture affects the slab, including site drainage, slab-edge risk areas and whether the moisture barrier appears correctly installed. While we don’t perform an arborist assessment, established trees can contribute to changing ground moisture over time. Catching drainage and slab-edge detailing issues early helps reduce the chance of movement and cracking later.
Typical issues include reinforcement not adequately supported off the ground, incorrect laps, barrier punctures or poor overlaps, and formwork details that don’t match the intended slab edge configuration. We also see penetrations placed awkwardly or without suitable protection, which can lead to slab cutting after the pour. A Stage 1 inspection is designed to find these items while they’re still easy to fix.
On narrower sites, set-out accuracy and slab edge details matter because there’s less tolerance for error near boundaries and existing structures. We pay close attention to formwork lines, step-downs, rebates and penetrations so the slab matches the intended footprint. We also look at drainage falls and slab-edge moisture risks, which can be harder to manage where outdoor space is limited.
Yes. Your report includes photos, clear descriptions of what was observed at the pre-slab stage, and practical recommendations so you can raise specific items with the site supervisor. The goal is to give you actionable information while corrections are still straightforward—such as repositioning mesh supports, repairing the moisture barrier, or adjusting formwork details—so the pour can proceed with fewer risks.
