Commercial underpinning Melbourne: stabilise, re-level and protect your asset

When floors dip or walls lean, a practical plan can stop damage and restore levels. Our focus is to calm anxious owners and managers with clear guidance, honest assessments and fixed-price quotes.

Who we help

  • Retail, hospitality, industrial, strata, healthcare and education facilities that need prompt action.

Signs a building needs attention

  • Look for new cracks, sticky doors, sinking slabs and tilted walls.

Our team inspects the site and the building to find the cause, not just treat the symptom. Where suitable, we use resin injection underpinning to fill 16mm holes, strengthen ground and re-level floors under survey control.

Expect improved integrity, clearer compliance and certified outcomes. We coordinate engineering reports and provide VBA-compliant certification so your property and access remain safe.

Underpinning methods and technology we use

Our team matches methods to site conditions so repairs are predictable and quick.

Resin injection is a fast, minimally invasive option. We drill 16mm holes, commonly to around 1500mm depth. A two‑part expanding resin fills voids, strengthens the ground and can lift slabs under continuous survey control.

Traditional concrete and screw piling

Concrete underpinning uses excavation and cast concrete. It suits deep edge beams or where a mass transfer is needed. Screw piling transfers loads to competent strata when near‑surface soils are poor.

Choosing the right approach

Method selection depends on soil profile, access, loads, services and operations. We use GPR to reduce service‑strike risk and survey equipment to track movement during lift.

  • Quick wins: resin injection is clean and suits operational sites.
  • Heavier work: concrete for deep beams, screw piles for high loads.
  • Our promise: we combine technology and calibrated equipment for a predictable process.

We recommend the method that suits your building, soil and operations. Contact us for a free assessment and fixed-price quote. Get in touch. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.

Our engineering-led process for commercial sites

We follow a staged engineering process that keeps your project controlled and clear. Each phase ties investigation to delivery so outcomes are predictable and documented.

Site investigation and diagnostics

We start with a structured site investigation. Soil profiling, moisture tracking and GPR locate services and risk without unnecessary excavation.

Solution design and report coordination

Diagnostics inform the scope. We design the underpinning plan and coordinate structural engineering sign-off. This keeps approvals fast and transparent.

Controlled injection or piling

Where required, we drill ~16mm holes. Survey equipment monitors lift during resin injection or piling. Holes are re-grouted and the site is cleaned on completion.

Quality assurance and handover

Our team uses calibrated equipment and proven technology. We verify levels, photos and test data to confirm quality.

  • We schedule works to fit trading hours and project milestones.
  • We manage compliance and provide VBA documentation and fixed-price quotes.
  • We brief your facilities team on maintenance and monitoring.

Our process reduces risk, time and re-work through applied knowledge. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au.

Why commercial foundations fail in Melbourne’s conditions

Foundations fail for clear reasons tied to soil, water and load. We explain causes calmly and show how to prevent recurrence. Our aim is safety and lasting repair.

Reactive clay soils: shrink‑swell cycles, drought and tree roots

Reactive clay absorbs water and expands. In drought it shrinks, causing subsidence and movement beneath slabs.

Trees and vegetation can change moisture near footings. That leads to uneven settlement and visible cracking.

Flooding, leaks and poor drainage: voiding and erosion beneath slabs

Leaking pipes and poor surface drainage wash fine material away. Voids form and the slab loses support.

We pair underpinning with drainage fixes to stop repeat problems and protect the structure.

Overloading and workmanship issues: inadequate founding and slab distress

Loads beyond soil capacity cause cracking and tilt. Inadequate founding on uncontrolled fill also triggers ongoing movement.

Adjacent excavations can undermine footings. Monitoring, improved drainage and correct founding prevent recurrence.

  • Practical outcome: we stabilise foundations and address moisture sources.
  • Experience: our industry knowledge across many years guides durable solutions for house and home style assets.

Timeframes, cost factors and minimising disruption

Clear timelines and staged delivery let owners plan trading hours around repair work. We tailor programs to suit your site and keep safety and access in mind.

Costs and delivery depend on method, access, soil type, severity and project size. We explain how each factor affects price and time so you can make an informed choice.

What affects price and schedule

  • Program and time depend on investigation findings and chosen methods.
  • Access, operating hours and service congestion influence delivery time.
  • Soil type and severity of movement affect scope, staging and work hours.
  • We use quiet equipment and small crews to reduce operational impact.

Fast-track delivery

Resin injection is often faster and less invasive than mass concrete solutions. Many resin scopes can be completed within a day for typical sites.

  • We sequence the project to protect tenants, stock and public access.
  • We provide a fixed-price quote with clear inclusions and exclusions.
  • We explain risk allowances, contingencies and ground conditions to reduce surprises.

Core services for commercial buildings

We provide targeted repair and foundation solutions that fit your operations and tenancy. Our services cover fast fixes and long‑term structural work so you can keep trading with confidence.

Concrete underpinning, resin injection underpinning and screw piling

Concrete underpinning gives mass support where excavation is viable. It suits edge beams and deep transfer requirements.

Resin injection strengthens the ground beneath slabs and can safely level floors using controlled expansion. We offer resin injection underpinning for minimal disruption.

Screw piling transfers loads to deeper strata and works well in tight access projects.

Restumping & reblocking, wall crack repairs and structural engineering reports

Restumping and reblocking extend life for timber house interfaces and mixed‑use home areas. We follow stabilisation with wall crack repair to restore appearance and performance.

FAQ

What signs indicate my commercial building needs foundation work?

Cracks in walls or floors, doors and windows that stick, sloping or uneven floors, and newly visible gaps at skirtings all signal foundation movement. Also check for fresh external settlement near downpipes or internal damp patches that suggest voids under slabs.

How do you decide between resin injection, concrete underpinning or screw piling?

We choose based on site access, soil type, building loads and the level of lift required. Resin injection suits fast, minimally invasive re-levelling. Concrete underpinning or screw piling is used where greater load capacity or deeper founding is needed. A site investigation and engineer’s report determine the right solution.

How long does a typical resin injection job take for a commercial property?

Many resin injection projects for light to moderate movement complete within a day. Larger or complex sites may need one to three days. We aim to minimise disruption and schedule work to suit your operating hours.

Will the repair be permanent and compliant with VBA requirements?

Yes. We design solutions to restore structural integrity and issue VBA-compliant documentation where required. Works are engineered, monitored during installation, and covered by warranties to give long-term performance.

What does your site investigation include?

We perform soil profiling, moisture tracking, and where needed GPR service locating. This identifies soil behaviour, buried services and the cause of movement. Findings inform the engineering design and method selection.

How much will underpinning cost my property?

Cost depends on method, soil condition, site access, severity of movement and project size. We provide a fixed-price quote after inspection and investigation. Contact us for a tailored, no-obligation estimate.

Will works disrupt my business operations?

We tailor programs to reduce impact. Resin injection is low-noise and quick. For larger piling or concrete works we plan staged access, off-hours work and clear safety controls to keep disruption minimal.

Are you insured and registered to carry out commercial foundation work?

Yes. We hold appropriate insurance and VBA registration. Our team delivers engineered solutions backed by industry-standard safety and compliance practices.

Do you provide structural engineering reports and certificates?

Yes. We coordinate with structural engineers to produce investigation reports, design documentation and handover certificates. These support insurance, strata requirements and council approvals.

Can tree roots or drainage cause slab movement?

Absolutely. Reactive clay soils combined with tree root water extraction, poor drainage or leaking services cause shrink-swell cycles and voiding beneath slabs. Addressing these drivers is part of a permanent solution.

How quickly can you start a project after inspection?

Start times vary with scope and approvals. For straightforward injections we can often schedule within days. Larger projects require engineering design and may take weeks. We provide realistic timelines in your quote.

Do you repair wall cracks and re-level at the same time?

Yes. We combine structural repairs such as crack stitching and reblocking with foundation stabilisation. Coordinating both ensures the structure is restored and the cause of damage is fixed.

What maintenance or monitoring is required after work is done?

Post‑work we supply monitoring advice and any recommended maintenance, such as improved drainage or root management. Some sites benefit from periodic checks to ensure long-term performance.
