What is helical pier underpinning and when is it used?
This engineered solution uses screwed steel shafts to reach firm strata below weak soils. We explain the method in plain terms so you can decide with confidence.
How steel shafts transfer loads to stable ground
The shafts are screwed through the soft topsoil until they reach competent ground. They take load from existing footings and foundations and move it to deeper strata.
We monitor installation torque to confirm capacity. That real‑time check verifies the engineered design and ensures the foundation will have reliable support.
Best-fit conditions: reactive clays, tight access and fast projects
This method suits reactive clay sites where seasonal movement causes settlement. It also works well where access is limited and large excavations are impractical.
There is no long concrete cure time, so the process is faster on time‑sensitive jobs. In some cases, geopolymer injection offers quicker slab lifting or ground compaction. We choose the right underpinning method after assessing soil profiles and site conditions.
| Condition | Recommended method | Key advantage |
|---|---|---|
| Reactive clay | Steel shaft system | Deep transfer of load; minimal excavation |
| Limited access | Screw shaft method | Small footprint; fast installation |
| Shallow subsidence | Geopolymer injection | Quick rise and ground compaction |

Signs your Melbourne home may need underpinning
We help homeowners spot problems early and respond with a calm, engineered plan. Small defects can be the first sign of a larger problem under the slab or footings. Early recognition saves time and cost.
Cracks in walls and slabs, jammed doors and sticking windows
Look for new or widening cracks in plaster, brick or concrete slabs. Hairline splits can grow into structural cracks if left unchecked.
Jammed doors and sticking windows often signal differential movement. Gaps in frames or skewed sashes may point to ongoing subsidence.
Uneven floors, leaning walls, and pooling water around footings
Uneven or sloping floors confirm settlement. A simple level check across a room can reveal a slope.
Leaned or bowed walls suggest foundation issues and need prompt assessment. Pooling water near footings shows poor drainage that softens soil and increases risk of subsidence.
- External step cracking in brickwork is a common field indicator.
- Persistent moisture and leaks at foundation level worsen movement in reactive clay conditions.
- Early diagnosis prevents further damage to finishes, services and structure.

Our diagnostic process: assessment to engineered solution
First, we map how the building is moving and record the causes on site. This lets us target the right fix quickly.
On-site structural assessment and site review
We begin with a free structural assessment to document movement patterns. Our team inspects footings, drainage and services for contributing issues.
Engineering report coordination and compliant design
We coordinate engineers and compile a VBA-compliant design package. That ensures council requirements and clear certification at handover.
Transparent scope, timeline and fixed-price quote
You receive a clear scope and a fixed-price quote before work starts. The quote lists inclusions and the installation sequence to avoid surprises.
- Soil and conditions review to understand reactivity and moisture.
- Explanation of why a chosen method suits your site and loads.
- Access, safety controls and temporary support are planned up front.
- Our experience helps anticipate risks and manage them proactively.
| Step | What we check | Outcome |
|---|---|---|
| Assessment visit | Movement mapping, footing checks, site photos | Documented diagnosis and scope |
| Soil review | Reactivity, moisture, concrete interface | Method recommendation and capacity checks |
| Design & quote | Engineered drawings, VBA compliance, fixed quote | Transparent timeline and council-ready package |
Helical piers vs other underpinning methods
Not every job benefits from the same structural repair; we match solution to site. We compare common repair types so you can see which suits your soil, access and budget.
Mass concrete underpinning: when traditional is the right method
Mass concrete underpinning uses staged excavation and concrete pours to extend footings to firmer ground. It works well where depths are modest and access allows.
Staged pits, reinforcement and curing time make this concrete approach reliable. It is often chosen for older structures with shallow footings.
Screw piling and micropiles: depth and access considerations
Micropiles and screw piling provide capacity at greater depths with less excavation. These types suit tight sites and sensitive structures.
They reduce disruption and let us work near services and adjacent foundations while delivering deep support.
Resin injection geopolymer options for crack closure and slab lifting
Geopolymer resin compacts weak soil and can lift slabs quickly. This method is efficient for localised cracks and shallow settlement.
We select the right type based on loads, soil profile, access and programme. We assess risks to nearby structures and recommend the least disruptive option.
| Option | Best for | Key benefit |
|---|---|---|
| Mass concrete | Shallow repairs, good access | Proven, durable concrete solution |
| Screw piling / micropiles | Deep variable soil, tight access | Minimal excavation; deep capacity |
| Resin injection | Localised slab lift, crack repair | Fast, low‑impact ground compaction |
We recommend the right method for your site and provide council‑ready documentation for the chosen approach. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.
Step-by-step helical underpinning process
We follow a clear, step‑by‑step process that turns a diagnostic report into certified foundation support. This section outlines the main stages so you know what to expect and why each step matters.
Site preparation, layout, and minimal-access installation
We prepare safe access points and set out pile locations to match the engineered drawings.
Minimal‑access rigs install the steel shafts with low noise and vibration. This reduces disruption to your neighbours and to internal finishes.
Torque-controlled installation and load testing
Torque is recorded continuously to confirm bearing capacity in real time.
We install test locations first to validate design assumptions before full production begins. Results are logged and compared to the engineer’s criteria.
Lifting, re-levelling, and structural verification
We connect new support to existing footings with engineered brackets and verified fixings.
Controlled jacking re‑levels slabs and walls within specified tolerances. We monitor levels and structural responses during lifting to prevent damage.
- Final checks: re‑torque, fixings inspection and as‑built records.
- Finish works: concrete infill or reinstatement where specified.
- Handover: certification and a concise maintenance guide at practical completion.
Costs and factors that influence pricing in Melbourne
We explain typical cost ranges and the main factors that change a quote. This helps you plan and decide with confidence.
Typical price ranges
Minor works often start around $5,000. These are localised fixes with good access and limited structural work.
Moderate projects usually fall between $10,000 and $30,000+. These involve larger areas, multiple support points or deeper soil work.
Complex jobs on larger buildings can exceed $50,000. Severe movement, difficult access and extensive reinstatement drive costs up.
Key drivers of cost
- Extent of damage: wider or deeper problems need more materials and time.
- Soil conditions: reactive clay, moisture and depth to competent layers increase scope and cost.
- Access: constrained sites add specialist equipment and protection works.
- Method selected: concrete underpinning or screw systems change programme and labour.
- Building size and layout: bigger houses need more piles, pits or concrete.
Why early intervention saves money
Small problems can escalate. Delaying repair raises the risk of damage to finishes, services and structural elements.
Early action often keeps a job in the lower cost band. It reduces time on site and the need for extensive reinstatement.
| Cost band | Typical scope | When to expect |
|---|---|---|
| Minor ($5k–$10k) | Localised support, small lifts, good access | Small cracks; early diagnosis |
| Moderate ($10k–$30k+) | Multiple supports, moderate re‑levelling, some reinstatement | Widening cracks; uneven floors |
| Complex (>$50k) | Deep support, large reinstatement, heritage or tricky access | Severe movement across large building |
