Our core services for stable, level homes
Our team delivers engineered solutions that steady foundations and protect your home investment.
We offer a suite of services tailored to local soils and building types. All work is VBA registered and insured. We coordinate engineering reports and permits where required.

Concrete underpinning for failing footings
Concrete underpinning adds mass under existing footings where deeper or stronger bearing is needed. It requires controlled excavation and engineered design to meet council and insurer requirements.
Restumping and reblocking to re-level timber homes
Restumping replaces failing stumps and re-levels floors to restore safe bearing for timber houses. Our restumping underpinning works use certified materials and precise jacking to avoid secondary damage.
Resin injection for fast, minimally invasive ground improvement
We use a two-part expanding polymer to fill voids and strengthen soil beneath slabs. Typical delivery uses 16 mm holes. Survey monitoring tracks lift and correction during treatment for verified outcomes.
Screw piling for deeper, stable load transfer
Screw piling transfers loads to competent layers with controlled torque and verified capacities. This method suits sites needing deeper support without large excavations.
Wall crack repairs that address cause and finish
We fix the cause first, then restore finishes to match surrounding fabric. Repairs combine structural repair and cosmetic restoration for a lasting result.
Structural engineering reports and council documentation
Engineering reports document the chosen solutions and satisfy council and insurer requirements. We provide fixed-scope quotes, certified drawings and compliance sign-off.
- Proven technology monitors movement and confirms level outcomes during the job.
- Expertise spans heritage homes, brick veneer, weatherboard and slab-on-ground buildings.
- Quality delivery via methodical planning, skilled crews and post-work certification.
- Ask for options and a fixed-scope solution for your home and soil conditions — see our comparison of restumping vs underpinning.
| Service | Primary benefit | Typical access / impact |
|---|---|---|
| Concrete underpinning | Increased footing bearing and depth | Excavation; engineered staging |
| Restumping & reblocking | Re-level floors and restore bearing | Local access under house; jacking and replacement |
| Resin injection | Soil strengthening and targeted lift | Small 16 mm holes; minimal excavation |
| Screw piling | Deep, verified load transfer | Machine-driven; low vibration |
| Wall crack repair & reports | Fix cause, certify result for council | Surface repairs and documentation |
Signs and causes of foundation problems in Port Phillip homes
Small changes inside the house can signal larger ground and foundation problems. Spotting them early reduces repair time and cost.
Cracks, sticking doors and sloping floors
Watch for stepped or diagonal cracks, doors that stick and floors that slope. These are clear warning signs of movement.
Sinking slabs often follow long dry spells when the soil beneath concrete shrinks or voids form.
Reactive clay, drought and tree influence
Local clay absorbs moisture and swells, then shrinks in drought. That cycle causes heave and settlement.
Mature trees can draw moisture from clay and create uneven movement near roots.
Drainage, leaking pipes and erosion
Poor drainage, flooding or leaking pipes wash fine particles from silty clays. This weakens bearing and creates voids.
Overloads, neighbouring works and poor workmanship
Extra loads or nearby excavation that cuts below footing levels can trigger subsidence. Waffle slabs on uncontrolled fill may settle if AS2870 was not followed.
- Early assessment limits further damage and helps define a targeted, compliant repair.
- If these issues appear at your house, book an engineering-led check and use our cost calculator.
| Sign | Likely cause | What to do |
|---|---|---|
| Diagonal cracks | Uneven settlement | Schedule an engineer inspection |
| Sticking doors | Floor tilt | Measure levels; monitor |
| Sinking slab | Soil shrinkage or voids | Soil test and targeted repair |
Our underpinning process Australians can trust
A structured assessment guides every step of the repair process we deliver. We lead with engineering, document the design and keep you informed at every milestone.

Site investigation and soil assessment
We start with a professional site investigation and soil assessment to find the cause of movement. Optional soil testing profiles layers and moisture for a clear technical picture.
Engineering-led solution and service location scanning (GPR)
Our engineering team defines the solution and sequence. We use GPR to locate services before any works begin.
Targeted injection or footing works with constant survey monitoring
Where resin injection suits the job, we mark injection points and drill small 16 mm holes to depths up to 1500 mm. Survey equipment records level change in real time so lift stays controlled.
Quality assurance, certification and clean site handover
Ports are removed or trimmed, holes regrouted and the site cleaned. You receive certification, drawings and compliance documentation at handover.
- Clear communication at key milestones.
- Safety and utilities managed throughout works.
- Quality checks verify engineered performance before sign-off.
| Step | What we do | Why it matters | Outcome |
|---|---|---|---|
| Investigation | Site review, soil assessment | Find true cause of settlement | Targeted solution |
| Planning | Engineering design, GPR scan | Safe works near services | Reduced risk |
| Delivery | Resin, concrete or piles with survey monitoring | Controlled lift and verified capacity | Stable foundation |
| Handover | Regrout, clean site, certification | Compliance and peace of mind | Documented completion |

Resin injection vs traditional concrete underpinning
A comparison of resin and concrete solutions shows clear differences in programme, mess and reach.
Speed, cleanliness and minimal disruption benefits
Resin injection uses a two‑part polymer that expands to fill voids. Install points are small — often 16 mm holes — so the work is fast and tidy.
This reduces site mess and noise. It also shortens the overall time on site and limits disturbance to the house and garden.
Improving ground conditions vs just adding mass
The technology stiffens weak soil and improves ground response beneath footings. That can stop ongoing movement by changing how soil carries load.
Concrete solutions rely on excavation and added mass. They increase depth and bearing but do not change soil behaviour the same way.
When concrete remains the right solution
Concrete underpinning stays necessary where deeper bearing or major structural rebuilding is required. For heavy loads or compromised foundations, excavation and mass concrete deliver verified capacity.
We assess each site and match the solution to your house, soil and the problem. You get an engineered process and a clear recommendation before work begins.
| Method | Primary advantage | Typical impact |
|---|---|---|
| Resin injection | Fast, low‑impact soil improvement | Small drill holes; short programme |
| Concrete underpinning | Increased footing depth and mass | Excavation; longer cure and site work |
| Screw piling | Deep verified load transfer | Machine-driven; suitable where depth is critical |
Compliance, certification and engineering oversight
We place engineering oversight and statutory compliance at the heart of each foundation repair. Your building gets a documented, council‑compliant approach from assessment to sign‑off.
VBA‑registered and insured — our company works under approved systems. We arrange permits, inspections and certificates so you do not need to chase paperwork.
VBA-registered, insured and council-compliant methods
All works are led by engineering and follow local council rules. We use methods that respect heritage and sensitive sites while protecting the customer with insurance and safe systems of work.
AS2870 considerations and structural reporting
We reference AS2870 when assessing founding depth, site class and slab behaviour in reactive soils. Non‑compliant founding on uncontrolled fill can cause settlement and distress.
- Structural reports document assumptions, design actions and the installed solution for your records.
- Quality control checks confirm the outcome aligns with the engineering intent.
- Our team brings years experience to complex soil conditions and constrained sites.
- Certification is issued at completion for lenders or future sale.
| Compliance item | What we provide | Why it matters |
|---|---|---|
| Permits & inspections | Permit applications and council inspections | Ensures legal approval and reduces future risk |
| Engineering reports | Designs, assumptions and verification | Clear record of works and basis for certification |
| Insurance & safety | Public liability and safe systems of work | Protects customer and site during works |
| Final certification | Compliance sign‑off and handover documents | Complete file for sale, lender or council |
