underpinning monash: common signs, local soil causes and when to act
Small changes in your home often signal larger ground movement beneath the footings. We explain the signs, likely local causes and when to call for an assessment.
Typical warning signs in homes
Look for visible cracks — stepped or diagonal cracks in walls, widening cracks near door or window openings, or new cracks that grow over time.
Watch floors. Sinking, bouncy patches or rooms that feel out of level often appear before other symptoms. Doors and windows that jam or rub are common early alerts.
How local soil and moisture affect footings
Monash sits on reactive clay that swells when wet and shrinks in dry spells. That cycle causes heave and settlement, stressing foundation elements and footings.
Reactive clay and changing moisture can create repeated movement. Over time, this leads to persistent cracks and uneven floors in a house.
Drainage, leaks and nearby works to watch
Poor site drainage or leaking stormwater and sewer pipes can wash fines from soil. This forms voids and weakens support under footings.
Excavations next door that cut below your footings can trigger local settlement. Act quickly if movement accelerates; early intervention limits repair scope.
- Stepped or diagonal wall cracks that lengthen.
- Sinking floors, gaps at skirtings and sticking doors.
- Persistent moisture changes in clay soils that affect the foundation.
| Sign | Likely cause | Immediate action |
|---|---|---|
| Diagonal or stepped cracks in walls | Settlement near footings or load changes | Book an engineering assessment |
| Sinking or uneven floors | Compacted or lost soil beneath slab or bearers | Investigate drainage and get a site inspection |
| Jammed doors and windows | Minor movement or seasonal clay shrink/swell | Monitor and schedule a timely review |
When to act: If new cracks appear or movement speeds up, call us. An engineering-led assessment will confirm whether the issue is seasonal, drainage-driven, or soil-related.

Our core services for stable, level structures
We offer a focused set of services to protect your building and restore peace of mind. Each job starts with an engineering assessment. Then we match the right method to soil, load and access conditions.
Concrete Underpinning for compromised footings
Concrete underpinning extends support and transfers loads to stable strata when footings fail. It requires excavation and several days for concrete to reach strength.
Restumping & Reblocking to re-support timber floors
Restumping and reblocking lift and re-support timber floors. This corrects uneven rooms and addresses movement at stumps and bearers.
Resin Injection for ground improvement and house re-levelling
Resin injection is non-invasive. It uses small holes, fills voids and cures fast. You can often use the area on the same day.
Screw Piling to deeper, more stable bearing strata
Screw piling bypasses weak layers and anchors into deeper strata. It’s efficient for stabilising heavier loads with limited disturbance.
Wall Crack Repairs to restore structure and appearance
We repair wall cracks after movement is stabilised. Repairs restore appearance and structural performance.
Structural Engineering Reports and VBA-compliant certification
Our team coordinates engineering reports and VBA-compliant certification. Every repair plan includes monitoring, verification and a fixed-price quote before work begins.
- We prefer minimally invasive methods first, reserving concrete where it is the best long-term answer.
- All services are council-compliant and designed to protect your property value.
Choosing the right method: traditional underpinning vs modern alternatives
Selecting a repair method balances durability, access and how quickly you need the property back. We explain the trade-offs so you can choose a safe, compliant solution for your foundation and structures.
Concrete underpinning: excavation, curing time and best-use cases
Concrete underpinning suits jobs that need deepened support. It involves excavation, soil removal, forming and poured concrete. Expect several days for curing before full load transfer.
Resin injection: keyhole access, fast curing and minimal disruption
Resin injection uses small holes to compact weak ground and fill voids. The resin expands in minutes. This method often lets you use the area the same day and keeps surface disruption low.
Screw piling: efficient way to bypass weak ground and stabilise
Screw piling is an efficient way to reach stable strata beneath poor soil. It transfers loads to deeper layers and reduces the need for large excavations.
- When to choose concrete: deep support is required and soil improvement alone won’t suffice.
- When to choose resin: minimal access, fast cure and low impact are priorities.
- When to choose screw piles: you need to bypass weak near-surface ground quickly and reliably.
We compare these methods against load, soil profile, access and risk tolerance. Each solution is engineered, council‑compliant and verified so you get a clear, long‑term outcome.
Our process and timeframes — from assessment to re-levelling
We begin each job with a clear, no-cost inspection to map movement and measure levels.
Free no-obligation structural assessment and honest diagnosis
We visit your site, perform level checks and use survey equipment to record baseline data.
We also use GPR when needed to locate buried services before drilling holes.
You receive an honest diagnosis and a fixed-price quote showing the scope and expected time on site.
Keyhole resin injection: compact weak ground, fill voids, lift where feasible
For resin re-levelling we drill small keyholes and plan injection points to target weak zones.
The expanding resin compacts soil, fills voids and can lift the building back to level.
Curing is rapid — typically around 30 minutes — so normal use can often continue during work.
Monitoring, levelling and council/VBA-compliant documentation
We monitor lift and levels continuously with survey gear to control outcomes.
Our team records before-and-after data for your property and for certification purposes.
On completion we coordinate structural engineering reports and VBA-compliant documentation.
- Free site assessment, level checks and diagnosis.
- Fixed-price quote with clear process and time expectations.
- Small holes for resin, service locating and targeted injections.
- Rapid cure, continuous monitoring and formal handover records.
| Stage | Typical work | Time on site | Outcome |
|---|---|---|---|
| Assessment | Site visit, level survey, GPR as required | 1–2 hours | Diagnosis and fixed quote |
| Resin re-levelling | Drill small holes, inject expanding resin, monitor lift | Half day to 1 day | Improved ground bearing and restored level |
| Major works | Concrete footings or screw piles, site safety management | Several days to weeks | Long-term deep support and compliance |

Costs, timing and expectations for Monash homeowners
How quickly we finish a repair and what it costs depends on soil, access and the chosen method.
What affects cost
- Soil behaviour: reactive clay or voided ground demands more work and raises cost.
- Access: tight yards or limited vehicle access increase labour and time.
- Method and extent: small resin jobs finish fast; concrete requires excavation and longer cure.
Fast turnaround with modern methods
Resin injection uses 6–16 mm holes and cures in about 30 minutes. Many residential jobs finish within a day. That means less mess and you can use areas sooner.
Traditional concrete underpinning needs excavation and several days for concrete to reach strength. This extends the program and affects the final cost.
Our quotes separate labour, materials, access allowances and engineering fees. We stage the job to protect gardens and keep safe access to your house and site.
| Factor | Impact on cost | Typical time effect |
|---|---|---|
| Reactive soil | Higher due to ground improvement | Longer assessment and stronger solutions |
| Site access | Access allowances or machinery hire | Slower mobilisation, longer job |
| Method chosen | Resin lower; concrete higher | Resin: 1 day, Concrete: several days |
