Townhouse foundation repair that keeps your home safe, level and compliant
Our certified team fixes foundation movement with targeted, low‑impact techniques and careful monitoring.
We prioritise safety and structural integrity. Our registered and insured crew uses council‑compliant methods that limit disturbance. Work is planned to protect the building and adjoining properties.
Resin or geopolymer injection compacts weak ground, fills voids and can lift foundations to close cracks and re‑level floors. The process uses 16 mm injection points, not mass excavation, so there is less mess and faster outcomes.
- We diagnose the cause of movement so the repair treats the source, not only symptoms.
- Methods stabilise the ground, support foundations and re‑level affected areas.
- We document findings and coordinate engineering sign‑off to keep your building compliant.
| Method | Disturbance | Typical outcome |
|---|---|---|
| Resin / geopolymer injection | Low (16 mm points) | Compacted ground, closed cracks, level floors |
| Concrete underpinning | Moderate to high | Deep support for failing footings |
| Screw piling | Low to moderate | Stable bearing into deeper strata |
Symptoms such as sticky doors, misaligned windows and gaps around frames are assessed in context. You get a clear scope, a fixed price and realistic timeframes before any works start. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au
Signs your Melbourne townhouse may need underpinning
Often the first signs are narrow cracks, sticking doors and windows that no longer square up. Settlement and voiding usually show as small symptoms before bigger damage appears. We inspect these early warnings to limit future repairs and cost.
Cracks in brickwork, plaster walls and external render
Widening wall cracks and stepped brick joints can signal differential settlement. Exterior cracking near downpipes may point to drainage‑related soil weakening.
Sticky doors, misaligned windows and gaps around frames
Sticky doors and racking windows often mean frame distortion from footing movement. Gaps around skirtings, cornices and frames show uneven support.
Uneven floors, slab movement and visible expansion joint changes
Localised floor dips or a sloping feel suggest slab or bearer settlement. Expansion joint changes and brick articulation movement reflect moisture swings in reactive soils.
- We measure, photograph and map symptoms to guide a targeted stabilisation plan.
- Resin injection can close fine cracks by lifting and re‑supporting slabs when ground is compacted during injection.
- Early assessment limits damage and may reduce the scope and cost of future works.
We offer free no‑obligation assessments to investigate these issues and provide a clear plan. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.
Why townhouses move: Melbourne soils, shared walls and site conditions
Soil behaviour and site activity combine to create gradual but damaging movement in many homes. We explain the main drivers so you can act early and avoid larger damage.
Reactive clay cycles
Melbourne’s clay soils swell when wet and shrink in dry spells. That shrink‑swell cycle causes heave and settlement that stress the building.
Poor drainage and erosion
Leaking pipes and ponding wash fines from silty clay. Flood or poor site drainage can create voids beneath slabs and lead to sudden loss of support.
Undermined footings and workmanship
Adjoining cuts or cut‑and‑fill works can leave footings unsupported. Overloading slabs or poor founding on fill increases long‑term settlement risk.
- We address moisture, tree roots and drainage upgrades alongside ground strengthening.
- Designs consider party walls and owners corporation needs to protect neighbours and property value.
| Cause | Typical effect | What we do |
|---|---|---|
| Reactive clay | Heave, settlement, cracking | Soil stabilisation and moisture control |
| Poor drainage / leaks | Voids, sudden collapse under slab | Drainage repair and targeted ground works |
| Adjoining excavations | Undermined footings along shared walls | Engineered support and staged works |

Underpinning solutions for Melbourne homes
Each site needs a tailored approach that balances speed, permanence and disruption. We provide core methods in‑house or work with trusted engineers to match the right solution to your goals and budget.
Concrete support for serious footing repair
Concrete underpinning adds mass beneath failing footings. It suits deep, localised restoration and complex structural repairs.
This work involves excavation and longer programs, but it restores bearing area and permanence where shallow soils are unreliable.
Resin injection for fast, clean soil stabilisation
Resin and geopolymer injection compact weak soils through 16 mm points. The method fills voids, lifts slabs and sets quickly with minimal mess.
It is ideal when access is tight and you want rapid, low‑disruption stabilisation.
Screw piling and steel solutions to reach competent layers
Steel screw piles transfer loads to deeper strata. They deliver reliable capacity with limited excavation and suit mixed soil profiles.
Complementary works and certification
We schedule crack stitching, repointing and finish repairs after ground stabilisation. Survey monitoring controls lift to protect finishes.
We coordinate structural engineering reports and VBA‑compliant certification so you get a complete, documented scope.
- Concrete suits deep restorations.
- Resin is fast and low‑impact.
- Screw piles reach competent bearing layers.
- Methods can be combined to suit mixed soils and access limits.
| Method | When used | Typical benefit |
|---|---|---|
| Concrete underpinning | Deep footing failure, complex restorations | Long‑term mass support and structural repair |
| Resin / geopolymer injection | Tight access, voiding, minor lifts | Fast set, low disruption, fills voids |
| Screw piles (steel) | Unreliable near‑surface soils | Transfer load to competent layers |
We never upsell. You receive a clear comparison of options, durations and expected outcomes. If you want advice, contact us or Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.
Underpinning for townhouse Melbourne: our calm, engineering‑led approach
We deliver calm, engineering‑led work that protects shared‑wall homes with minimal disruption.
Minimal disruption with small 16 mm injection points
Our process uses 16 mm injection points to avoid mass excavation. We run GPR checks first to clear services on the site.
Staged works limit vibration and protect adjoining walls. This reduces mess and shortens program time.
Lift and level: compact weak ground to close cracks
Survey instrumentation monitors lift as we compact weak ground. We aim to restore level and close fine cracks without major finishes work.
VBA‑compliant methods and council‑ready documentation
We prepare engineering certification and paperwork suitable for council and owners corporation records. You get clear scope and a fixed‑price quote before work starts.
Tailored to shared walls, tight access and owners corporation needs
Our team plans around your household and neighbours. We communicate with owners corporations and adjacent owners during every stage.
- We plan around your daily routine.
- GPR service checks precede any drilling.
- Survey‑controlled lifting helps protect finishes.
- Clean‑up and re‑grouting restore presentation.

Our underpinning process: assessment to certification
We begin every job with a clear, evidence‑led inspection that maps symptoms and site risks.
Free, no‑obligation assessment includes moisture tracking and soil profiling. We measure movement, photograph defects and log environmental data to target the issue.
Design and set‑out
Design work follows the assessment. We run GPR checks to locate services before any drilling.
Plans define injection depths or concrete footing details. Where resin is used we set 16 mm drill points to about 1500 mm and stage volumes to compact soils and fill voids progressively.
Execution and quality assurance
Survey instruments monitor lift in real time. This controlled approach protects finishes and adjacent structures.
Re‑grouting and careful patching complete a tidy finish. Concrete workflows use excavation, enlarged footings and staged pours, taking longer but suited to deep failures.
- Assessment maps symptoms, moisture and soil to target rectification.
- Design defines depths, safety controls and set‑out.
- GPR clears services to avoid strikes during drilling.
- Survey monitoring controls lift and records movement.
- Final documentation includes VBA‑compliant certification and post‑works checks.
We provide fixed‑price quotes after inspection and coordinate engineering reports so you get clear scope and certified outcomes. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au
