Local foundation issues in Maribyrnong: why timely action matters
Reactive clay under local streets causes movement that can show up as cracks and uneven floors. Wet periods cause heave. Dry periods cause shrinkage and subsidence. These cycles put your house and building at risk over the years.
Poor drainage, leaking pipes or blocked stormwater wash fines from beneath slabs. That creates voids and sinking slabs. Tree roots draw moisture and speed shrinkage. Early signs include hairline cracks in walls, sticky doors and a sloping floor.
Timely investigation prevents larger costs and protects property value. We prioritise safety and VBA-compliant work. We assess your site, explain the process in plain language and match the best solution to your building and area.
- Free, no‑obligation assessment and a fast, written fixed‑price quote.
- Clear reports for insurance, compliance and future sale needs.
- We schedule the job to minimise disruption and keep you informed.

Our core services for homes in Maribyrnong
Our team delivers a targeted suite of foundation services tailored to local homes and soil conditions. We choose methods that suit your house, not a one-size-fits-all fix. Expect clear advice, engineered design and minimal disruption.
Concrete underpinning for sinking footings
Concrete work supports sinking footings and heavier building loads. It suits deeper movement and provides permanent strength.
Restumping and reblocking
Restumping and reblocking replace ageing stumps beneath floors and internal walls. This re-levels floors, removes bounce and stabilises timber and brick veneer homes.
Resin injection — fast slab re-levelling
Resin injection lifts slabs through small holes. It is clean, quick and reduces time on site. Ideal when excavation must be minimal.
Screw piling, wall repairs and reports
Screw piles move loads to deeper layers for reactive clay or fill. We repair cracks after movement is fixed and supply structural engineering reports.
- Services designed for your property: no generic fixes.
- We protect landscaping and reduce site time.
- Written scope & fixed-price quote before any work begins.
Choosing the right solution: traditional underpinning vs resin injection
A tailored solution protects your home and limits disruption. We assess the depth of movement, the condition of footings and the local soil before recommending a path. Our focus is on safety, compliance and long‑term performance.

When concrete methods suit your property
Concrete underpinning is best when movement is deep or loads are heavy. It involves excavation beneath footings and uses concrete and steel for permanent support.
This method can take more time and needs good access. We only recommend it when the building and foundation require the added strength.
Resin injection — fast, low‑impact lift
Resin injection improves the soil by filling voids and increasing bearing. Typical holes are about 16 mm and 1500 mm deep.
It suits slabs and light footings. Works are quicker, cleaner and often finished in a day. That makes it a high‑quality option when minimal disturbance is needed.
Screw piles for reactive or deep fill soils
Screw piles bypass weak layers and transfer loads to stable strata. They are ideal for highly reactive soil or where fill is deep.
| Method | Best for | Disruption | Typical outcome |
|---|---|---|---|
| Concrete | Deep movement, heavy loads, complex footings | Higher (excavation required) | Permanent structural support and stability |
| Resin injection | Slabs, light footings, void filling | Low (small drill holes) | Rapid lift, improved bearing, minimal landscaping impact |
| Screw piles | Reactive soil, deep fill, high risk sites | Moderate (machine access) | Loads transferred to competent layers |
- We assess your building, footings and soil and recommend the least invasive solution that works.
- We explain the expected works, timeframes and quality outcomes before you approve the plan.
- We consider future drainage, restumping and reblocking needs to protect the foundation long term.
Our engineering-led process from inspection to certification
A methodical engineering process guides every job, from site checks to final certification.
We start with a free structural assessment and a clear, fixed-price quote. Our goal is to identify causes quickly and plan practical works with minimal disruption.
Site investigation and soil/moisture assessment
Our team inspects the site, records levels and notes visible defects. We test soil and monitor moisture. Weather and watering patterns are reviewed to define the profile.
Solution design, GPR service locating and quote transparency
We map injection or footing points and use GPR to locate underground services before any drilling. You get a transparent quote showing inclusions and exclusions. There are no hidden allowances.
Implementation: drilling, injection or footing works, real-time level monitoring
Our crew completes drilling, resin injection or concrete footing works with protection measures in place. Resin rows use 16 mm holes about 1500 mm deep when suitable.
Survey gear monitors lift in real time. We stop work when targets are met to protect finishes.
- We coordinate engineering reports for projects that need specialist input.
- Holes are regrouted, the site is cleaned and minor reinstatement is done.
- We issue VBA‑compliant certification and photos on completion, and we schedule follow-up if needed.
| Stage | What we do | Benefit |
|---|---|---|
| Investigation | Soil tests, moisture tracking, level survey | Clear cause and correct solution |
| Design & Quote | GPR, mapped points, fixed-price quote | Safe works and budgeting certainty |
| Implementation | Drilling/injection/footings, real-time monitoring | Controlled lifts and minimal disruption |
| Completion | Regrout, tidy site, certification | Compliance, documentation and peace of mind |
underpinning maribyrnong — signs, causes and local risk factors
Small changes in your home can reveal larger issues below the surface. We explain common signs and local causes so you can act calmly and with confidence.

Common signs to watch for
Look for stepped or diagonal cracks near openings. These often appear first in affected walls.
Doors that stick or rub and a sloping floor signal differential movement. Sinking slabs and wider cracks need prompt assessment.
Local causes that drive movement
Soil here is reactive. It expands in wet periods and shrinks in drought. That cycle causes heave and settlement.
Tree roots and garden irrigation shift moisture. Leaking pipes or poor drainage wash fines and create voids beneath slabs.
Overloaded slabs can exceed bearing capacity and crack. Nearby excavation that cuts below footing depth also raises risk.
Practical steps to prevent future movement
Home owners reduce risk by improving drainage. Keep water away from footings and repair leaks quickly.
Maintain even mulch and watering around the perimeter. Avoid extremes that stress clay.
Our team inspects and explains findings. We plan the job to target the root cause and complete work with minimal time on site so your family can usually stay at home.
| Risk sign | Likely cause | Immediate action |
|---|---|---|
| Stepped/diagonal cracks in walls | Uneven settlement from reactive soil or voids | Book an inspection and level survey |
| Sticky doors, sloping floor | Differential movement from moisture cycles or root activity | Check drainage and tree watering; call our team |
| Cracked or sinking slab | Voids from leaking pipes or overloaded slab | Locate services, repair leaks, and plan remediation |
Pricing, free quotes and what influences the cost
Costs for foundation work vary widely, so we outline the main drivers clearly.
We offer a free no‑obligation structural assessment and a transparent, fixed‑price quote. Our visit clarifies the scope in writing and shows what the site needs.

- Price depends on movement depth, access and soil behaviour.
- Resin injection is often cleaner and faster using small 16 mm holes.
- Concrete methods need excavation and more time, which affects cost.
- Restumping costs reflect number and condition of stumps and floor relevel needs.
We coordinate engineering reports and include clear inclusions, exclusions and provisional items in every quote. That way the customer has no surprises.
| Cost driver | How it affects price | Typical outcome |
|---|---|---|
| Extent of movement | More movement needs more material and labour | Higher cost, longer job time |
| Access | Tight access increases labour and specialised gear | Moderate to higher cost |
| Soil type | Reactive clay or deep fill needs deeper solutions | Choice of resin, screw piles or concrete |
| Method chosen | Resin is faster; concrete is more invasive | Lower vs higher reinstatement costs |
We provide best value by matching method to cause and staging the job. Home owners receive clear payment milestones and documentation aligned to progress.
Ask about restumping underpinning combinations where both are needed. We share our years of experience and comparable ranges so you know what to expect before approval.
