We offer fast, professional foundation solutions and free assessments for homeowners who need reliable, VBA‑compliant work.
We are Underpinning Melbourne — structural preservation specialists with years of industry experience. Our calm, engineering‑led team protects your home with clear reports, fixed‑price quotes and coordinated engineering.
We assess the causes of foundation issues, explain practical options and recommend the least disruptive path to lasting stability.
Modern geopolymer resin can stabilise weak ground and raise footings, often closing cracks without full concrete excavation. Where concrete pads are needed, we use controlled jacking and hydro vacuum excavation to reduce risk to underground assets.
Your safety and structural integrity are our priority. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au to book a no‑obligation assessment.

Do you need underpinning? Signs, symptoms and common causes in Whitehorse
Early signs of foundation distress are often subtle, but they tell a clear story about your home’s stability. We explain what to watch for and when to act.
Cracks, gaps and uneven floors: when your home structure is talking to you
Look for diagonal wall cracks, doors or windows that stick, and skirting board gaps. These are common indicators of movement.
Wavy plaster, separated cornices or widened mortar joints point to uneven floors and settling foundations. Early attention can avoid bigger problems.
Reactive clays, leaking pipes and poor drainage impacting strip footings
Many older homes sit on shallow strip footings. These footings are sensitive to changing soil conditions.
Reactive clay shrinks and swells with seasonal water changes. Leaking plumbing and poor stormwater drainage wash away subgrade and speed movement.
- Tree roots can dry local soil and cause localised subsidence.
- Minor repairs suit some cases; engineered underpinning is safer when damage is widespread.
- We offer a free photo review to indicate if an engineer assessment is needed.
Most issues can be stabilised with a tailored plan that treats both cause and consequence. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au to send photos and book an assessment.
Our core services for stable, durable foundations
We combine proven methods and modern materials to protect your home and its value. Our team is VBA registered and fully insured. We work to minimise disruption and keep sites tidy.
Concrete underpinning (traditional underpinning) for long-term stability
Staged excavation and reinforced concrete pads restore bearing capacity. Where needed, controlled jacking helps close fissures and re-establish load paths.
Restumping and reblocking for timber and ageing homes
We replace degraded stumps and reblock frames to level floors and protect timber structures.
Resin injection to re‑level floors and close cracks
Resin compacts weak ground and can lift settled slabs. This often closes cracks faster than full dig‑and‑pour options.
Screw piling for challenging soil conditions
Steel screw piles transfer loads to deeper bearing strata. They suit sites with inconsistent or reactive near‑surface soils.
Wall crack repairs and make‑good
We check lintels, repair cracks and reinstate finishes so your house is ready for paint and handover.
Structural engineering reports and council compliance
We coordinate engineer designs, certification and council paperwork to keep your project compliant and efficient.
- Hybrid techniques when mixed conditions demand a tailored solution.
- Tidy sites, daily clean‑ups and respectful access management.
- Fixed‑price quoting available — try our cost calculator.
| Service | What it does | Best for |
|---|---|---|
| Concrete pads | Rebuilds bearing capacity with reinforced concrete | Severe settlement and long-term stability |
| Resin injection | Compacts soil and lifts slabs with minimal excavation | Localised settlement and floor re‑levelling |
| Screw piles | Steel piles transfer loads to deeper strata | Variable soils and reactive clay sites |
| Restumping | Replaces timber stumps and reblocks frames | Ageing timber houses with uneven floors |
Underpinning methods explained: choosing the right solution for your home
A practical solution depends on site tests, engineer advice and the level of movement. We use simple diagnostics and local soil data to match the best method to your house.
Traditional concrete underpinning: staged excavation and reinforced pads
Traditional underpinning uses staged excavation beneath existing footings. We place reinforced concrete pads one section at a time to avoid sudden movement.
Controlled jacking may be used to reduce gaps while new pads cure. This solution is best for significant settlement where long‑term stiffness is needed.
Modern geopolymer / resin solutions to compact weak ground and lift slabs
Resin systems inject geopolymer into voids to compact weak soil and lift settled slabs. Installation is quick and causes minimal excavation.
Real‑time monitoring lets us stop when lift targets are met. For localised problems this process can be faster and less disruptive than full concrete works.
Screw piles: steel solutions for deep, reliable bearing
Screw piles are steel shafts that bypass poor near‑surface soil and transfer loads to deeper competent layers. They suit sites with variable soil and where access allows pile installation.
They provide immediate working load capacity and are often paired with concrete or resin in hybrid scopes.
- Compare trade‑offs: disruption, speed, cost and permanence.
- Soil testing: essential to choose the correct process for each location.
- Hybrid solutions: concrete, resin and steel can combine when conditions vary under one building.
| Method | Disruption | Speed | Best for |
|---|---|---|---|
| Concrete pads | Moderate to high | Weeks (including cure) | Severe settlement needing durable bearing |
| Resin injection | Low | Hours to days | Localised slab lift and void filling |
| Screw piles (steel) | Moderate | Days | Variable soils and deeper support needs |

underpinning whitehorse — local soil conditions and typical foundation issues
Seasonal shifts in moisture drive most movement we see under older houses. Reactive clay in Melbourne expands in wet months and shrinks when dry. That cycle places changing loads on shallow strip footings.
How seasonal moisture and reactive clays affect foundations
Dry summers pull moisture from the soil and cause shrinkage. Wet winters rehydrate the ground and swell the same soil.
These changes can open cracks, tilt walls and create uneven floors. Surface and subsurface water from leaking pipes or poor stormwater drainage worsen the problem.
Strip footing vulnerabilities and how we mitigate them
Older strip footings are shallow by modern standards. They sit close to variable soil, so they move more when moisture changes.
- Improve drainage: better gutters, downpipes and perimeter drains reduce water at the footing edge.
- Fix plumbing leaks: repairing leaks removes a common source of subsurface erosion.
- Landscaping: use swales or graded planting to keep water away from the building.
- Choose the right repair: concrete pads suit deep, long‑term fixes; resin is fast for local lifts; piles help where soils vary.
- Monitor outcomes: short‑term gauges confirm stabilisation before internal finishes are reinstated.
| Risk | Mitigation | When to use |
|---|---|---|
| Reactive clay cycles | Manage surface water, regular inspections | All older homes with strip footings |
| Leaking or pooling water | Fix plumbing, install drains and grade landscaping | When erosion or soft spots appear |
| Variable bearing strata | Use screw piles or concrete pads | Where soil tests show inconsistency |
| Local slab settlement | Resin injection for targeted lift | Small, localised settlement issues |
Timely action limits repair scope and protects your building over seasonal cycles. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au to discuss a tailored plan.
Costs, timelines and what to expect
Knowing likely costs and realistic timeframes helps you plan with confidence. We explain the main drivers so you can compare options and pick a solution that suits your life and budget.
What influences costs and time on site
Scope size, access constraints and the chosen method all shape final costs. Engineer reports and council conditions add time and fees.
Resin methods often cut program time and reduce disruption compared with dig‑and‑pour concrete. Hydro vacuum excavation speeds safe access where services exist.
Transparent fixed‑price quotes and value for money
We provide fixed‑price quotes that list inclusions, exclusions and contingencies. That keeps price surprises to a minimum during the job.
- Cost drivers: scope, access, method, engineering and council fees.
- Typical time ranges: resin (hours–days), concrete pads (weeks), screw piles (days–weeks).
- Early drainage and plumbing fixes can reduce later repairs and overall costs.
- We stage work when needed to match budget and living arrangements.
| Item | Typical time | When used |
|---|---|---|
| Resin injection | Hours–2 days | Local slab lift, minimal access |
| Concrete pad (staged) | 2–6 weeks | Severe settlement, long‑term fix |
| Screw piles | 1–7 days (per area) | Variable soils, deeper support |
Our process focuses on efficient sequencing, daily clean‑ups and monitoring so your house stays functional. We include warranty, monitoring and certification in every quote.
