We answer which method will best protect your Melbourne home in plain terms: one transfers loads to deeper, stable ground while the other renews stumps under a house to correct sagging floors and doors.

We are Underpinning Melbourne, Structural Preservation Specialists. Our mission is to save homes from foundation failure with a calm, engineering‑focused approach. We offer Concrete Underpinning, Restumping and other core services in the region.

Typical signs of movement include cracked walls, sticking windows and sloping floors. Underpinning suits subsidence and settlement by adding deep support. Reblocking usually restores houses on stumps after about 20 years or where drainage and soil change cause movement.

Expect a clear path from assessment to certified repair. Our team has over 20 years’ experience, uses VBA‑compliant methods, and provides fixed‑price quotes with minimal disruption. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.

What is underpinning and what is reblocking? Foundations, signs and causes

Understanding what causes settlement helps you act early and avoid bigger repair costs. We explain both approaches simply and relate them to local soil behaviour.

Underpinning explained: strengthening failing foundations and stopping settlement

Underpinning extends or strengthens an existing foundation. Technicians excavate in stages and install mass concrete or piles. The new supports bear on deeper, stable soil and stop further settlement.

Reblocking/restumping explained: replacing deteriorated stumps to re‑level floors

Restumping, called reblocking locally, replaces failed stumps under timber floors. Workers remove rotten stumps and fit new supports to re‑level floors and restore load paths.

Common causes of foundation problems in Victoria’s soils

Melbourne’s reactive clay swells and shrinks with moisture. Poor drainage, leaking pipes, tree roots and bad compaction make conditions worse. These factors change soil beneath a building and cause movement.

Typical signs at home: cracks in walls, jammed doors and windows, uneven floors

  • Hairline cracks in plaster or masonry
  • Sticking doors and tight windows
  • Sloping or uneven floors
Issue When it applies Outcome
Deep settlement Mass concrete or piles needed Load moved to stable soil; further damage arrested
Local stump failure Timber stumps rotten under floors Floors re‑levelled; local support restored
Soil moisture change Drainage, roots, leaking pipes Root cause addressed to reduce recurrence

We assess the whole building to decide if underpinning or restumping is right. For a detailed comparison, see our restumping and underpinning comparison.

underpinning vs reblocking melbourne: which service is right for your house?

Selecting the best repair starts with a clear diagnosis of where the movement comes from.

When brick walls or slab edges have lost bearing because of changing soil, choose underpinning. Mass concrete pits extend the footing to deeper, stable ground and stop further settlement. This is the right service for subsiding foundations on masonry or slab buildings.

When restumping suits timber‑floored homes

Choose restumping for timber floors on rotten stumps where sagging causes doors to stick and rooms to be out of level. It is local, faster and less invasive than deep excavation. Expect quick re‑levelling and restored load paths.

Pros, cons and expected outcomes

  • Underpinning: stops settlement, stabilises the building, precise re‑levelling; needs access and staged excavation.
  • Restumping: rapid local fix, minimal disruption; won’t fix deep ground problems.
  • We balance cost, access and long‑term performance to recommend the correct service.

Alternative or complementary supports

Resin injection can densify weak pockets. Screw piling provides deep end‑bearing where loads and site conditions require higher capacity.

Solution When it fits Outcome
Concrete underpinning Subsidising brick or slab Long‑term stabilisation
Restumping Rotten stumps under timber floors Floors levelled, quick return to use
Resin / Screw piles Weak pockets or deep capacity needs Targeted support with less excavation

Conclusion

A prompt inspection can stop small soil changes becoming major foundation problems.

Underpinning halts settlement by transferring loads to deeper, stable strata. Restumping restores support where stumps have deteriorated. Clay soil movement is a common cause of these issues, so early action limits further damage and cost.

We diagnose the soil and site conditions first. Then we recommend the right repair: underpinning, restumping or targeted concrete work. Our services include engineered reports, permits and certification so projects run smoothly.

FAQ

What is the difference between underpinning and reblocking?

Underpinning strengthens or replaces failing concrete or masonry foundations by installing new supports beneath them. Reblocking, also called restumping, replaces deteriorated timber stumps beneath timber‑floored homes to re‑level and stabilise the house. Both address settlement but target different foundation types and causes.

How do I know if my house needs foundation work?

Common signs include cracks in walls, jammed or misaligned doors and windows, uneven or sloping floors, and gaps at skirtings. If you see repeated movement or new cracks, get an assessment from a licensed structural engineer and an experienced foundation contractor.

What causes foundation problems in Melbourne and Victoria?

Typical causes are reactive clay soils, poor drainage, tree roots, long droughts followed by heavy rain, and aged or corroded stumps. These conditions lead to soil movement and uneven support under floors and slabs.

When is underpinning recommended instead of reblocking?

Choose underpinning for concrete slabs, brick foundations or where the load‑bearing elements need new engineered supports. Underpinning suits properties with deep or complex settlement issues that timber stump replacement cannot resolve.

When should we opt for restumping/reblocking?

Restumping is appropriate for timber‑floored homes on stumps where the timber is rotten, termite‑damaged or the stumps have settled. It’s a targeted repair that restores floor level and access beneath the house.

What does the repair process involve for underpinning?

The typical underpinning workflow includes a site investigation, structural engineer’s design, staged excavation beneath the footing, installation of new concrete or screw pile supports, re‑levelling, and final certification. Work is staged to maintain structural safety.

What is the restumping workflow?

Restumping begins with stump assessment, removal of old stumps, installation of new engineered stumps (concrete, steel or screw piles), re‑levelling the floors, and cleaning up. We protect existing finishes and minimise disruption throughout.

How long will the work take and how disruptive is it?

Duration depends on property size and method. Typical restumping jobs take days to a few weeks. Underpinning can take longer. We plan work phases to reduce disruption and protect interior finishes. Your project manager will give a clear timeline in the quote.

Do I need permits and engineering reports?

Yes. Structural engineering reports and council permits are usually required for foundation repairs in Melbourne. We work with VBA‑registered engineers and manage council compliance and certification for you.

Are there alternatives to traditional underpinning or restumping?

In some cases, resin injection for void filling or screw piling can be an alternative or complement. The right approach depends on soil conditions, load requirements and the engineer’s assessment.

Will repairs fix cracks and restore property value?

Properly designed and executed foundation works restore structural integrity, re‑level floors and reduce further cracking. This stabilises the building and helps protect property value. Cosmetic repairs to cracks are recommended after structural stabilisation.

How do you guarantee your work and what insurance do you carry?

We provide workmanship warranties and work under comprehensive public liability and contract works insurance. All structural changes are certified by a registered structural engineer and are council‑compliant.

How much will a foundation repair cost and can I get a fixed quote?

Costs vary with the extent of works, foundation type and access. We offer free, no‑obligation assessments and transparent fixed‑price quotes after a site inspection and engineering report.
