Carlton North builds often sit on tight inner-city blocks with older neighbouring footings, large street trees and drainage constraints—small base-stage errors here can lead to cracking, damp and boundary disputes later.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check the ground has been properly prepared before formwork goes in, including subgrade condition, compaction signs, any soft spots, and whether debris and organic material have been removed. In Carlton North’s tight blocks, poor subgrade preparation can be hidden under fill and lead to differential settlement once the slab is loaded.
We assess formwork alignment, bracing, slab thickness allowances and edge beam configurations as visible, including levels and falls where relevant. Correct set-out is essential on narrow sites in Carlton North where boundary clearances and finished floor heights often need to match existing homes and laneway or courtyard levels.
We inspect reinforcement placement for common issues such as incorrect lap lengths, missing bars, inadequate cover, and mesh not supported on chairs. If steel sits too low or is displaced before the pour, the slab’s performance can be compromised, increasing the risk of cracking and movement.
We check the membrane type and installation quality, including tears, punctures, joins, taping and upturns at edges and penetrations. In Carlton North, where ground floors can sit close to external paving and garden beds, a continuous barrier helps manage moisture migration that can affect floor finishes and indoor comfort.
We review plumbing and other penetrations for placement, sleeving where applicable, sealing approach and whether openings are formed correctly. Getting penetrations right before the pour helps avoid later cutting or drilling, which can damage reinforcement and create pathways for moisture and pests.
We look for practical drainage considerations visible at this stage, such as provision for falls, stormwater points or subsoil drainage where specified, and whether the base stage work is likely to trap water against the slab edge. Poor water management is a common trigger for damp and slab edge issues on inner-city sites.

Find answers to the most frequently asked questions about our inspection service.
On narrow Carlton North blocks, access is limited and slabs are often built close to boundaries and existing structures. That makes it harder to correct levels, edge details and drainage once concrete is poured. A Stage 1 pre-slab inspection checks formwork set-out, reinforcement placement and membrane continuity while everything is still visible, so issues can be fixed without demolition or disputes with neighbours.
Book as soon as your builder schedules the steel and membrane installation. The inspection needs to occur after site preparation, formwork and reinforcement are complete, and the moisture barrier is installed, but before the concrete pour. In Carlton North, pours can be organised quickly due to tight timelines and limited street access, so early booking helps ensure we can attend at the right time.
Your report includes annotated photos and clear notes on any observed issues with subgrade readiness, formwork, reinforcement and moisture barrier installation. We also list practical recommendations for rectification before the pour, so you can send a focused list to your builder or site supervisor. The report is written to support decision-making without relying on vague language or assumptions.
They can. Carlton North streets often have established trees and many properties sit beside older homes with existing footings and boundary structures. While a pre-slab inspection doesn’t replace engineering advice, we pay close attention to site preparation quality, soft or disturbed ground, edge beam detailing and moisture management around slab edges. These factors can influence movement and moisture behaviour once the home is built.
Yes. Carlton North builds frequently involve rear access via laneways or constrained side passages. We coordinate with your builder to attend when the base stage is ready and safe to inspect, and we work within site rules and access limitations. If any areas are not visible or are unsafe to access, we note that clearly in the report so you understand the inspection scope.
