Finding cracks in your walls or noticing your floors starting to slope can be pretty stressful for any property owner. 

The city’s shifting weather and reactive clay soils can put real pressure on structures, which is why finding the best foundation repair pros in Brisbane early really matters.

You might first spot these issues while planning something like a backyard deck repair, or when trying to properly waterproof your lower level before heavy rain hits. 

But ignoring foundation movement can quickly turn into bigger structural damage or even affect your property’s value when it’s time to sell.

So, we’ve looked into local structural repair specialists across the city to help you find reliable teams that actually fix sinking foundations properly, without unexpected costs popping up later.

1. Buildfix

Website: https://www.buildfix.com.au/ 

Address: 7/35 Learoyd Rd, Acacia Ridge 

Contact: 1300 854 115

Hours: Monday – Friday: 8:00 AM – 5:00 PM

Dealing with sinking slabs becomes much simpler when one team handles both the engineering assessment and the structural repair without any handovers. 

You’ll find that at Buildfix who are is known for having their own structural engineers lead every job, so you’re not dealing with sales reps or subcontractors along the way. 

They use an Australian-made GeoPoly resin system to lift and stabilise foundations through small injection points, often completing the work in just one to two days.

They also offer a 20-year product and workmanship warranty, plus fixed pricing, so the quote you receive is exactly what you pay with no surprises. 

I spoke to a local homeowner who was impressed with how tidy their backyard stayed during the whole process.

However, communication can sometimes feel a bit slow or unclear during the early booking stages, which is something to be aware of upfront.

For anyone needing reliable underpinning or foundation repair services

Kurt and Jared did an outstanding job on the underpinning work at my home. They were professional, knowledgeable, and took the time to explain every step of the process clearly. Their workmanship was top-notch — the site was kept clean and tidy throughout, and the results are rock solid. I’m really impressed with their attention to detail and the way they handled the job efficiently and safely. It’s great to see tradespeople who truly take pride in their work. Highly recommend Buildfix, especially Kurt and Jared, for anyone needing reliable underpinning or foundation repair services.

Very satisfactory

Really happy with Buildfix and all the staff members. Bruno took the time to explain everything that was to happen on the day, and how it worked. Andy and Pedro were a pleasure to deal will as they were both very professional and personable. Again, they took time to explain at the beginning and end of the work, taking the time to answer patiently all my questions. The result (raising the foundation of my extension back to where it belong) was very satisfactory. I highly recommended this company.👍👍👍👍👍

2. GROUNDFIX – Foundation Repair

Website: https://www.groundfix.com.au/

Address: 291 Bowen Terrace, New Farm 

Contact: 430 081 404

Hours: Monday – Friday: 7:30 AM – 4:30 PM

Sunken driveways and cracked brick walls need a specialist who understands how local soil movement affects concrete structures. 

GROUNDFIX shows that knowledge in permanent foundation stabilisation and sunken slab repairs across Queensland, using their SecurePier system to restore stability. 

They also offer free home inspections and detailed quotes, so you can understand the issue before committing to any work.

Backed by a 15-year workmanship warranty, this team works on both residential foundations and external concrete areas like patios and pool surrounds, making them a strong option for broader structural issues. 

Just keep in mind that they focus purely on structural repairs, so you’ll need a separate contractor if you’re looking for cosmetic upgrades or landscaping work.

The work was completed quickly and efficiently

Excellent slab lifting service at our property on the Gold Coast. Our concrete slab had started to settle, but the issue was clearly identified and explained before the work began. The work was completed quickly and efficiently, and the floor is now perfectly level again. Very professional service with great communication throughout the whole job. Highly recommend their foundation repair services.

Highly recommend his foundation repair services

We contacted them for foundation repair here in Gold Coast after noticing cracks in our walls. They inspected everything carefully and explained the cause clearly. The repair was done professionally and we feel much more confident about the structure now. Highly recommend his foundation repair services.

3. Foundation Solutions

Website: https://foundationsolutions.com.au/

Address: Tenancy A – 2847 Old Cleveland Rd, Chandler 

Contact: 451 824 961

Hours: Monday – Friday: 7:00 AM – 5:00 PM

Heavy structural subsidence usually requires proper engineering solutions rather than quick surface-level fixes. 

Foundation Solutions focuses specifically on serious foundation movement, using Katana Foundations screw pile technology to permanently stabilise shifting homes and restore structural integrity. 

The business is led by directors Nicole Rosenthal and Jason Edmonds, who together bring more than 30 years of hands-on structural engineering experience to every inspection and project.

They also offer free home assessments and use specialised lift rigs designed to reduce disruption during the repair process. 

During a property inspection, I noticed how precisely their piling system can lift and re-level heavy structures without tearing up lawns or causing major damage to surrounding outdoor areas, a big relief for homeowners.

Their fixed pricing model is another plus, helping avoid unexpected cost blowouts once work begins. 

The only catch is that there are occasional communication delays, often linked to internal tracking system updates, and that can slow down responses during busy periods.

Extremely knowledgeable and patient 

Nicole has been extremely helpful to us, she turns up on site on time and provided us with initial assessment of the foundation of our house. She is extremely knowledgeable and patient despite it’s only a complementary site assessment. Nicole is also extremely honest and helpful to our proposed renovation project. I would no doubt continue using her service and recommend anyone who requires foundation repair or related services they provide.

4. Mainmark QLD

Website: https://mainmark.com/ 

Address: 20 Computer Rd, Yatala 

Contact: 1800 623 312

Hours: Monday – Friday: 9:00 AM – 5:00 PM

Fixing an unlevel home doesn’t always need deep trenches or weeks of disruptive excavation. 

For example, Mainmark QLD uses their proprietary Teretek expanding resin technology to lift and stabilise sinking foundations. This non-invasive injection system fills underground voids and strengthens weak soil, allowing the area to be used almost immediately after treatment.

With over 36 years of ground engineering experience, their in-house engineers oversee ISO-accredited processes to ensure each structural lift is carried out with precision and care. 

They also offer an impressive 50-year product warranty on their resin, which provides strong long-term confidence, especially for older or heritage-style homes.

Unfortunately, you can’t get a quick phone quote, as they require a full site inspection first to determine whether resin injection is suitable for your specific soil conditions.

Very professional 

Such an enjoyable experience from the first visit to completion of the work. The work team on the day of foundation repair was very professional and also friendly and informative as the works proceeded.

I highly recommend Mainmark and the repair process they implemented on my house. Thanks to all the workers.

5. MP Underpinning

Website: https://mpunderpinning.com.au/

Areas Served: Bethania 

Contact: 449 088 806

Hours: Monday – Saturday: Available 24/7

Restricted property access can make traditional structural repairs nearly impossible on tight inner-city blocks. 

MP Underpinning addresses this issue using a specialised tripod drilling rig designed to work in confined spaces where larger equipment simply won’t fit. 

They offer a range of remediation services, including foundation stabilisation, pressure grouting, and even removing tree roots that can damage concrete footings.

The team is fully licensed with the Queensland Building and Construction Commission (QBCC), and they’re known for leaving very little disruption or mess behind once work is complete. 

They’re particularly effective at repairing shifting brickwork and fixing issues like doors and windows that no longer close properly due to movement.

Just a heads-up, though: weather can play a big role in scheduling, and heavy rain can delay projects significantly. 

Some clients have also mentioned that communication tends to slow down once the main work is completed.

Very professional in the entire process

I needed to underpin some block walls that were cracking due to the poor condition of the slab and footings. Mal was very professional in the entire process. When I needed additional work done outside of the original scope he was able to accommodate it. Jai and Brendan that work with Mal were hard working and really friendly. Would recommend these guys without any hesitation.
