underpinning maroondah
Seasonal soil swings close to the surface can lead to slow, hidden damage to building footings.
Local conditions: reactive clay, drainage and tree effects
Much of the area sits on reactive clay that expands when wet and shrinks when dry. This movement stresses footings and causes gradual settlement.
Poor drainage and leaking pipes wash away soil and form voids under slabs. Tree roots and garden irrigation change moisture near footings and make conditions worse.
When to act: small signs that point to deeper problems
Early signs are often subtle. Look for new hairline cracks, sticking doors and uneven floors.
These small signs can precede bigger issues and lasting damage to your home or building. Acting in time prevents spread.
- We assess soil behaviour and moisture patterns at the site.
- Our advice focuses on practical, durable rectification with minimal disruption.
- You receive clear next steps and an indicative fixed price.

Common signs and causes of foundation problems
Small changes in your home often point to deeper foundation faults that deserve prompt attention. We explain common signs and likely causes so you can act early without alarm.
Warning signs inside your house
New diagonal cracks in brickwork or plaster and sticking doors often show differential movement. Gaps at cornices or skirtings and uneven floors are escalation signs.
Reactive clay and seasonal soil swings
Reactive clay expands when wet and shrinks when dry. These cycles push and pull on footings over time and create progressive cracking and settlement.
Poor drainage and water erosion
Ponding near footings, leaking drains and sewer faults wash away soil and form voids. Loss of support leads to local subsidence and visible damage to walls and slabs.
Construction, overloading and workmanship
Inadequate founding, overloaded slabs or non‑compliant fill can cause ongoing settlement. Waffle slabs on poor fill may settle if not built to AS2870 guidance.
- New diagonal wall cracks and sticking doors indicate differential movement.
- Gaps at cornices, uneven floors and sinking slabs show escalation.
- Ponding and leaking pipes often undermine local soil support.
- Overloaded slabs and poor workmanship increase settlement risk.
- Our inspections find causes, not just treat symptoms, and outline suitable underpinning options.

Our core services for Melbourne homes
We provide a full range of foundation services tailored to local soils and building types. Our approach is engineering‑led, VBA Registered and insured. We aim for durable results with minimal disruption to your routine.

Concrete work for deeper support and stability
Mass concrete methods increase bearing depth using staged excavations. This delivers long‑term support where deeper founding is required. We select concrete materials and designs to suit your foundation and load.
Restumping and reblocking to renew stumps
Restumping re‑levels timber floors and replaces worn stumps. Our team fits new stumps to restore floor level and prevent future movement. The work is tidy and scheduled to reduce disruption.
Resin injection to strengthen soil and lift slabs
Polyurethane injection uses small 16 mm holes to fill voids and improve soil. It can lift slabs quickly with minimal excavation and mess. This is ideal when you need a rapid, low‑impact repair.
Screw piling for difficult soils and heavy loads
Screw piles suit varying founding depths and tight access sites. They offer durable, low‑disturbance support for heavier loads. Our team designs pile layouts to match the site.
Wall crack repairs and engineering reports
We repair cracks only after movement stabilises. Structural engineering reports support council permits and insurance needs. One coordinated team delivers quality work and clear documentation.
- Concrete increases bearing depth for long‑term stability.
- Restumping and reblocking renew stumps and re‑level floors.
- Resin injection lifts slabs with minimal mess.
- Screw piling suits limited access and variable depths.
- Engineering reports and repair work provide compliance and peace of mind.
Choosing the right method: concrete underpinning vs resin injection vs screw piling
Not every house suits the same solution; soil, access and building type guide our choice. We explain the practical trade‑offs so you can choose with confidence.
Traditional mass concrete: excavation, staging and long‑term support
Concrete methods increase bearing depth using staged excavations. This delivers permanent support where deeper founding is required.
Note: mass concrete can be time‑consuming and does not always improve ground conditions beneath the slab.
Resin injection: minimally invasive, rapid lift and soil improvement
Polyurethane injection fills voids and strengthens soil through ~16 mm holes drilled to about 1500 mm. It allows a quick lift with minimal excavation.
This method suits projects where speed and low disturbance matter. It targets local soil weakness rather than replacing large volumes of ground.
Screw piles: durable, low‑disturbance option
Screw piles transfer loads to deeper strata where founding depth varies. They suit tight access sites and heavier loads.
Screw piling reduces excavation and performs well across variable profiles.
What suits your project: matching method to site and time
We match methods to soil tests, the structure and access constraints. Materials and design focus on long‑term stability and compliance.
- Concrete is ideal where deeper founding is required.
- Resin injection fixes voids and lifts slabs quickly.
- Screw piles work where founding depth fluctuates with minimal excavation.
- Each project weighs budget, time and acceptable disturbance.
- Solutions may combine techniques to control risk.
We provide fixed‑price quotes and an engineered work plan. You receive a tailored design and a staged program to minimise internal movement and disruption.
Our process: assessment, engineering and compliant execution
We begin every project with a focused site review that maps soil, moisture and buried services. This initial step gives clear data so we can define the right solution for your building and foundation.

Free no‑obligation assessment and soil profiling
Step 1 is a free assessment. We test soil and track moisture to find causes and extent of movement.
Engineering‑backed planning and GPR locating
Step 2 is design. Our engineers mark injection or pile locations and use GPR on site to avoid services.
Works on site with monitoring and minimal disruption
Step 3 covers the work. For resin we drill ~16 mm holes to about 1500 mm, install ports and inject. Our team monitors lift with survey gear and keeps disturbance low.
Documentation and clean handover
Step 4 completes the job. We regrout holes, tidy the site and deliver VBA‑compliant certification plus council‑ready reports. You get a fixed‑price quote, coordinated engineering and scheduled follow‑ups to confirm integrity over time.
- Free assessment with soil profiling.
- GPR locating to protect services on site.
- Continuous level monitoring by our team during works.
- Materials installed under strict QA controls.
- Clean handover, certification and ongoing checks.
| Step | On‑site action | Outcome |
|---|---|---|
| 1 | Soil testing & moisture mapping | Clear cause and risk report |
| 2 | GPR, layout of injection/piles | Safe work plan for the team |
| 3 | Drilling, injection/piling, monitoring | Lift and restored support |
| 4 | Regrout, clean, certification | Handover with VBA reports |

Pricing, quotes and what affects cost
Costs for foundation work change a lot depending on what we find under your property.
We give transparent, fixed‑price quotes based on site data and an engineered scope. That keeps surprises low and helps you compare value, not just price.
What drives price: soil, access, method and complexity
Soil behaviour and the extent of movement are the main drivers of cost. Deeper founding or extensive erosion requires more work and time.
Access and internal finishes influence the chosen method. Traditional mass concrete can take longer and disturb more. Resin injection is faster and minimally invasive, using 16 mm holes and level monitoring to lift and fill voids.

Transparent, fixed‑price quotes and coordinated engineering reports
Our fixed‑price quotes outline scope, inclusions and assumptions. We coordinate engineering reports to streamline approvals and reduce delays.

| Driver | Effect on price | Typical outcome |
|---|---|---|

| Access & finishes | Increases labour and protection needs | Longer time on site |
| Method chosen | Varies by disturbance and materials | Faster resin or longer concrete works |
