Save your home with the 5 best foundation repair pros on the Gold Coast!
A fresh driveway might lift your kerb appeal, but it won’t help if the house is slowly sinking. Before hiring paving contractors, I’d want to know the ground underneath is safe and stable.
Cracked walls, uneven floors, and doors that suddenly stick aren’t just annoying little quirks. They can point to foundation movement that needs a proper expert, not a quick cosmetic patch.
That’s why I looked into the best foundation repair on the Gold Coast before planning any upgrades. These local specialists can help steady your home and keep bigger repair bills from cracking the budget.
How much does foundation repair cost in Gold Coast?
Foundation repair on the Gold Coast can cost anywhere from $1,500 to over $30,000. The final price depends on the damage and repair method.
Minor crack stitching usually costs $1,500–$4,500. Resin injection generally ranges from $3,000–$10,000+.
Traditional concrete underpinning costs around $800–$1,500+ per pier. A full underpinning job may total $10,000–$30,000.
1. Mehrtens Underpinning & Construction
Address: Unit 13/28 Expo Ct, Ashmore
Contact: (07) 55 924 893
Hours: Monday-Friday, 9 AM – 4 PM
Mehrtens Underpinning & Construction brings more than 35 years of claimed experience to serious structural repairs across Queensland and Northern New South Wales.
I like that they don’t rely on a single fix for every job. Their services include reinforced concrete piers, screw piers, hydraulic jacking, pressure grouting, and other solutions for sinking or unstable foundations.
They’re also set up for tight-access sites, which is handy around established Gold Coast homes. Third-party structural engineering certification is included with underpinning projects, adding another layer of reassurance.
The downside is that traditional concrete underpinning appears to be their main focus. Moreover, resin injection isn’t listed among their advertised services.
2. National Construction & Remedial Pty Ltd
Areas served: Gold Coast, Brisbane, Northern NSW
Contact: 07 5528 4212
Hours: By appointment
National Construction & Remedial brings more than 30 years of combined industry experience to waterproofing, crack repair, and concrete remediation.
I like that they investigate what’s causing the damage instead of simply covering the visible mess. Their services include polyurethane crack injection, spalling repairs, protective coatings, and structural strengthening.
They also work closely with strata managers, body corporates, and structural engineers. That makes them a practical choice for larger Gold Coast apartment, commercial, and remedial projects.
The catch is that they’re more focused on concrete repair and waterproofing than traditional foundation underpinning.
Homeowners with sinking slabs or minor settling should confirm the job suits their services before booking.
3. Resinject
Address: 76 Minnie St, Southport
Contact: 1300 091 441
Hours: By appointment
Foundation repairs don’t always need to turn your yard into an excavation site. For example, Resinject uses engineered polyurethane resin to stabilise weak soil, fill voids, and lift affected slabs with far less disruption.
I like that the process is designed to be quick and tidy, which suits built-up Gold Coast properties. Its Australian-made RSJ170 resin expands underground and sets in about 60 seconds.
The company also offers a 50-year product guarantee against resin shrinkage. That’s reassuring, though it shouldn’t be confused with a blanket warranty covering every future structural issue.
The downside is that its repair options centre almost entirely on resin injection. Anyone after traditional concrete underpinning or another stabilisation method will need to compare other contractors.
4. Mainmark QLD
Address: 20 Computer Road, Yatala
Contact: 1800 623 312
Hours: Monday-Friday, 9 AM- 5 PM
Mainmark has worked in ground engineering since 1989 and remains a well-established name in resin-based foundation repair.
I like that its team assesses the structure before recommending a fix. Its services include resin injection, slab lifting, void filling, ground improvement, and other low-impact remedial work.
Mainmark also handles residential, commercial, infrastructure, and heritage projects. That range makes it a strong option for tricky Gold Coast sites where access, age, or fragile materials complicate repairs.
The downside is that traditional concrete underpinning doesn’t appear to be part of its advertised service range.
It’s also a specialist remedial firm rather than a general builder, and full re-levelling won’t be possible on every property.
5. JAYPAX Group
Areas served: Gold Coast, Brisbane, Ipswich, Toowoomba, the Sunshine Coast, and parts of Northern NSW
Contact: 1800 879 596
Hours: Monday-Friday, 8.30 AM – 4 PM
Foundation movement is stressful enough without turning the yard into a construction zone. Thankfully, JAYPAX Group uses expanding resin to support footings, lift slabs, fill voids, and tackle unstable ground with minimal excavation.
I like that they combine laser levelling and digital mapping with the inspection process. They also work on older Queenslanders and character homes, where a one-size-fits-all fix usually won’t cut it.
The company describes itself as veteran- and family-owned, with warranties of up to 50 years on eligible projects. Its tidy, low-impact approach could suit busy Gold Coast homes where access and disruption matter.
The downside is that its services centre mainly on resin-based remediation rather than traditional underpinning or general building work.
Warranty length and re-levelling results also depend on the job and site conditions.
