Ashburton rebuilds and townhouse projects often involve tight side access, cut-and-fill blocks and reactive clay conditions—small base-stage mistakes can lock in drainage and slab issues once concrete is poured.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess whether the base has been prepared to the required levels and looks consistent with the intended slab set-out. This matters on Ashburton infill blocks where regrading and cut-and-fill can create low points that trap water under the slab if not corrected.
We check formwork alignment, bracing, step-downs and slab edge details so the slab is formed as designed. Correct edge detailing helps avoid exposed slab edges, uneven finishes and problems tying in external paving and drainage around narrow side paths.
We inspect reinforcement type where visible, spacing, overlap and whether mesh/bars are properly supported on chairs to achieve cover. If steel sits on the ground or is poorly lapped, the slab may not perform as intended and cracking risk increases.
We look for membrane continuity, tears, penetrations, lapping and taping so the barrier can do its job. In Ashburton, where damp conditions can be an issue through winter, a compromised membrane can allow moisture migration that affects floor coverings and indoor air quality.
We check the placement and sealing approach around plumbing and other penetrations, plus any set-downs for showers or wet areas where visible. Errors here are hard to fix after the pour and can lead to water ingress paths or uneven floor transitions later.
We review visible site falls and how water is likely to move away from the slab during and after construction. On compact Ashburton sites, temporary and permanent drainage decisions made at base stage can reduce ponding against slab edges and help protect the build during rain events.

Book it for the window after the base is prepared and formwork, reinforcement and the vapour barrier are installed, but before any concrete is poured. On Ashburton townhouse sites, this can move quickly once trades are on site, so it helps to book as soon as you receive a pour date. We can liaise with your builder to confirm the right time.
No. Stage 1 is strictly the base stage before the slab is poured. We focus on site preparation, formwork, steel reinforcement, moisture membrane and visible penetrations and drainage set-up. Waterproofing is typically reviewed at a later stage, and framing is assessed during a frame inspection once the structure is up. Stage 1 is about what will be permanently buried by concrete.
Yes, access constraints can affect how materials are placed and how neatly the base stage is finished. We pay close attention to membrane damage from foot traffic, reinforcement being pushed out of position, and whether edges and set-downs are formed cleanly in tight spaces. We also consider how water will move around the slab area during rain when there’s little room for temporary drainage.
They can be. Many Melbourne suburbs, including Ashburton, can experience soil movement depending on moisture changes. While we’re not doing a geotechnical report, we do check that the slab preparation and reinforcement installation look consistent with a build that needs good control of moisture and proper structural detailing. Getting the base stage right helps the slab cope as intended with ground conditions.
You’ll receive a detailed report with photos, clear descriptions of what we observed, and actionable recommendations prioritised by urgency. The report is written so you can forward it directly to your builder or site supervisor and request rectification before the concrete is poured. If needed, we can clarify items so you understand what to ask for and why it matters.
