Signs your house needs underpinning in Nillumbik’s clay soils
Small cracks and sticky doors can signal serious ground movement under your house. These symptoms often start subtly. They then progress as clay soils react to wet and dry cycles.

Watch for clear warning signs in brickwork and timber. These indicate footing movement and possible subsidence in reactive soil.
Common symptoms: stepped brick cracks, sticking doors, sloping floors and sinking corners
- Stepped cracks that track along mortar in your brick walls.
- Doors that begin to stick or scrape, especially external doors.
- A sinking external corner or uneven floors showing subsidence in the ground.
- Gaps at window heads or out‑of‑square reveals signalling wall movement.
- Hairline cracks that widen seasonally in clay soil conditions.
- Bowing walls, misaligned sills and loose bricks as structural warning signs.
- Problems that worsen after heavy rain or prolonged dry spells.
If you notice two or more of these signs, your house may need underpinning soon. Early assessment reduces further damage and makes repairs more efficient.
Free no‑obligation structural assessments and fixed‑price quotes are available if you recognise these symptoms. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au to book an assessment so we can confirm causes and stabilise your home.
Underpinning Nillumbik: our core services to stop subsidence and restore level
We offer engineered services that stop movement and return your home to true level. Our works focus on cause‑based repair and clear scopes to minimise disruption.
Concrete underpinning for deeper, stable footings
Mass concrete underpins and beam‑and‑base systems extend footings to deeper bearing strata. This concrete method is ideal where weak ground needs bypassing.
Restumping and reblocking to re‑level timber homes
We replace decayed supports and re‑level timber floors with new stumps and blocks. See our restumping vs underpinning guide for details.
Resin injection for targeted soil stabilisation and lift
Geopolymer resin compacts weak soil and can lift settled slabs with minimal excavation. It is fast and causes little disruption.
Screw piling for wet, sandy or reactive soil conditions
Screw piles and micropile‑style supports suit wet or sandy ground and tree‑affected sites. They provide reliable capacity and adjustable support.
Wall crack repairs and council‑ready engineering reports
We repair cracks after the foundations are stabilised so repairs last. Registered engineering reports and VBA compliance are included.
| Service | When used | Benefit |
|---|---|---|
| Concrete underpinning | Reactive clay or weak bearing strata | Deep, durable footings and long‑term level |
| Restumping & Reblocking | Timber homes with decayed stumps | Restores floor level and renews supports |
| Resin injection | Localised settlement, slab lift | Minimal excavation and fast lift |
| Screw piling | Wet, sandy or tree‑affected ground | Adjustable, high capacity support |
We match method to your building, loads and site constraints. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.
Choosing the right method for your foundations and soils
Choosing the correct method starts with a quick, practical assessment of your soil, access and the extent of movement. We inspect your site and discuss options that fit safety, council rules and budget.

Mass concrete underpins, beam-and-base and when they’re best
Mass concrete and beam‑and‑base systems suit many homes where deeper bearing is reachable. Conventional mass concrete underpins commonly go to about 2.1 m depth to reach stable ground.
Beam‑and‑base spreads loads and can bridge softer ground. This method is reliable where clay or weak soil needs a durable foundation solution.
Screw piles and micropile-style support for problem ground and trees
Screw piles perform well in wet or sandy ground and tight access areas. They underpin walls and edges with minimal excavation.
Micropile‑style options suit deeper supports or tree‑affected zones. These methods manage tree‑induced moisture variation and reduce ongoing movement.
Modern resin/geopolymer solutions as a fast, minimally invasive alternative
Geopolymer resin can stabilise soil and lift settled slabs quickly. It causes little disruption and is often a cost‑effective way to close cracks and re‑level floors.
We provide honest recommendations and never upsell. Our engineers select the method, sizes and spacing to address subsidence. You get a clear method statement that explains the steps, risks and contingencies.
Our process: calm, transparent and compliant from first inspection to certification
From inspection through certification, we keep the process clear and calm for homeowners. We aim to remove uncertainty and to solve foundation issues with a planned, staged approach.
Free no‑obligation structural assessment and fixed‑price quote
Book your inspection and we’ll review your home on site. You receive a written assessment and a transparent, fixed‑price quote.
Engineering design, permits and VBA‑compliant execution
Our team coordinates engineering design and building permits early. Works proceed under registered engineer oversight and VBA‑compliant documentation.
Minimal disruption, careful excavation and clean site handover
We sequence excavation to protect the structure and services. Excavation is staged to control ground stability and reduce risk.
Engineers inspect at key milestones. We monitor ground and structure as each stage is finished.
- Time on site is minimised by planning and clear communication.
- We resolve issues quickly to avoid delays to your job.
- You receive certification and records for future property needs.
- We leave the site clean and safe for your family.
| Stage | What happens | Control points |
|---|---|---|
| Inspection | Free site visit and written assessment | Initial engineer review and fixed quote |
| Design & permits | Engineer drawings and permit lodgement | Council approvals and VBA paperwork |
| Excavation & install | Staged excavation to protect services | On‑site engineer inspections and monitoring |
| Handover | Final inspection and certification | Compliance records and clean site |

Pricing, timelines and what to expect in Nillumbik projects
We explain cost drivers and schedule so your project proceeds without surprises. Our approach gives you a clear quote after a short assessment. That helps you plan budgets and household arrangements.
What drives cost, how long the job takes and how we reduce downtime
Costs depend on depth to bearing, soil behaviour, access and the length of affected walls. Engineering requirements and provisional sums also affect price.
Time on site varies by method. Typical jobs take several days to a few weeks. We stage work to limit disruption and protect finishes while we restore level.
We reduce downtime through early material planning, clear sequencing and milestone checks. You get regular updates and inspection hold points during the process.
Photos and plans we can assess before a site visit
Send photos and plans for a quick preliminary assessment. This early review speeds the formal assessment and shortens the time to a fixed quote.
- Pricing depends on depth, soil and access constraints.
- We confirm scope after inspecting cracks, levels and footing condition.
- You receive a fixed‑price quote that lists inclusions and exclusions.
- Expect clear updates on job milestones and control points.
