Signs your Casey home may need underpinning
Small changes in doors and floors can reveal a large problem beneath your house. Cracks, sticky doors and uneven floors are common early warnings of soil movement and subsidence.
Cracks in brickwork, sticky doors and uneven floors from soil movement
Cracks in brickwork or internal walls often mean parts of the footing have moved while others stayed stable. This differential movement leaves visible gaps and separates sections of a wall.
Look for stepped cracks in external brickwork and diagonal cracks near windows and doors. Sticky or misaligned doors suggest the frame has racked due to foundation movement.
Uneven or sloping floors can point to subsidence or footing rotation under the home. Hairline cracks that widen over time show ongoing soil movement.
- Gaps between skirting and floors or between cornices and ceilings are red flags.
- Cracks that open and close seasonally indicate reactive shrink–swell behaviour.
- Water pooling near footings can soften soil and speed up damage.
Early inspection limits repair scope, cost and disruption. We provide free, no‑obligation structural assessments to confirm the problem, explain the process and outline repair options. We never upsell unnecessary work.
See our wall crack diagnosis tool for quick guidance: wall crack diagnosis. If you spot these signs, book an inspection and we will confirm the issue and stabilise the foundation.
Underpinning Casey: proven methods tailored to local clay soils
We match proven methods to local clay soils to deliver long-term stabilisation for your home. Our engineering-led approach selects the best technique for the ground and structure.
Concrete underpinning, restumping and reblocking
Concrete underpinning increases bearing area and supports settled foundations permanently. Restumping and reblocking renew timber stumps and re‑establish floor levels in older homes.
Resin injection and Geopoly geopolymer soil stabilisation
Resin stabilisation densifies weak ground and can lift settled sections faster than heavy excavations. Geopolymer-style resin compacts ground and helps close cracks and re-level floors efficiently.
Screw piling for deeper, stable bearing strata
Screw piling transfers loads to deeper strata where near-surface clay is reactive. We design pile length and depth to reach consistent capacity below active layers.
Hydro vacuum excavation for fast, clean and low-risk digs
Hydro vacuum excavation uses high-pressure water and a vacuum to form precise digs. It can create block pads around 1 m x 1 m x 1.8 m or bored cavities to 4 m depth x 450 mm diameter.
- We choose the right method for your ground, goals and budget.
- These techniques reduce excavation risk and protect underground utilities.
- Every solution is engineered to control movement and protect foundations long term.
| Method | Purpose | Typical depth / size |
|---|---|---|
| Concrete underpinning | Increase bearing area and permanent support | Pad depths to engineered spec |
| Resin / Geopolymer | Densify ground and lift settled areas | Shallow injections to deep lift zones |
| Screw piling | Transfer loads to stable strata | Piles to designed depth (m) |
| Hydro vacuum excavation | Precise, low-risk excavation near services | Block pads 1 x1 x1.8 m or bored to 4 m |
Our underpinning process and safety standards
Our work follows a clear, safety-first process that protects your building and records every step. We prioritise safety, structural integrity and VBA-compliant certification. You get council-ready reports and engineer-signed documentation.
Investigation, soil and structural assessment, and engineering reports
We start with site investigation and soil testing to understand ground behaviour and depth to stable strata. An engineer designs pad sizes, depth and the best techniques for your ground.
Pin installation, minimum seven-day concrete cure and multi-jack re-levelling
Pins are set out and safe excavation prepares the bearing ground. Concrete is poured and allowed a minimum seven‑day cure before any re-levelling.
Hydraulic jacks sit between new pads and existing footings. We use a multi-jack system with small, even lifts to control movement and protect walls. Each jack can be rated to around 50 tonnes.
Steel plates and dry pack grout to lock the footing and prevent movement
Once levels are restored, we install steel bearing plates and pack any gaps with dry pack grout to lock the footing. If original footings are brittle, full closure of cracks may not be possible; we explain this up front.
- Quality checks record levels, wall crack changes and final foundation tolerances.
- Safety controls protect people, services and your home during every stage of the job.
- We coordinate engineering reports and provide certificates and council-ready paperwork at completion.

Project timelines, site access and service areas across the City of Casey
We map access, logistics and excavation needs early to avoid surprises on the day. This helps us set realistic timeframes and reduce homeowner stress.
Local areas we service: Berwick, Cranbourne, Narre Warren, Clyde, Beaconsfield and nearby suburbs. Our team confirms the program and dates after an initial inspection and soil review.
Most small projects take several days on site plus engineering lead time. We lock in timeframes once we review access and ground conditions.
How we manage access, digs and disruption
- We assess site access and choose safe excavation methods for your house and building.
- Hydro vacuum excavation is used where access is tight. It creates block pads ~1 m x 1 m x 1.8 m deep or bored cavities to ~4 m depth x 450 mm diameter.
- We plan pad positions, depth and logistics to suit the ground and the structure.
- Expect daily updates on progress, milestones and any weather-related changes.
| Item | Typical | Benefit | Notes |
|---|---|---|---|
| Small projects on site | Several days | Quick reinstatement | Plus engineering lead time |
| Hydro vacuum excavation | Pad 1 x1 x1.8 m / bored to 4 m depth | Protects underground services | Ideal for tight driveways |
