The 5 Best Basement Waterproofing Services in Brisbane for Keeping Dampness Away
The best basement waterproofing in Brisbane is crucial if you want to protect your property’s foundation from severe water damage.
A lot of homeowners only worry about waterproofing bathroom floors, but your below-ground spaces face intense moisture pressure that demands expert attention.
Landlords managing investments and buyers inspecting new homes will both lose money if they ignore a damp, leaky sub-grade level.
Hiring experienced waterproofing contractors ensures you tackle the root cause of the moisture rather than just covering up the ugly wet spots. We found the top local professionals to help you secure your investment.
How much does basement waterproofing cost in Brisbane?
Basement waterproofing in Brisbane costs typically range from $500 for minor repairs to over $15,000 for complex, large-scale structural jobs.
| Job Complexity | Estimated Cost Range (AUD) |
| Basic (Small/Simple Fixes) | $500 – $1,500 |
| Mid-Range (Typical Residential) | $2,000 – $5,000 |
| Premium (Large/Complex Projects) | $5,000 – $15,000 |
1. WS Remedial Group QLD
Website: wsrg.au
Address: Unit 4, 10-12 Russell Street, Petrie
Contact: 1800 005 000 | [email protected]
Hours: Monday-Friday, 8:30 AM – 4:00 PM
WS Remedial Group QLD brings some serious technical expertise to complex basement leaks. They tackle difficult water ingress using their own patent-pending waterproofing systems rather than relying on standard off-the-shelf products.
Because the majority of their on-site team holds formal trade licensing, you get a much higher level of skill and consistency than what standard Queensland regulations require.
Moreover, they hold an Open Builder licence. This means they can fix major structural defects right alongside the waterproofing work without calling in outside contractors.
Apparently, a friend recently dealt with a stubborn leak in their commercial property. They couldn’t stop raving about how this team handled the repairs without shutting down their daily operations.
Just keep in mind that if you need them to inject leaks behind existing tiles, they charge extra for the protective core-drilling required to keep your finish intact.
Expert waterproofing advice for residential design
I contacted Chris requesting expert advice on a unique residential design requiring attention to a waterproofing detail. Chris reviewed the design and was very thorough, informative and was able to provide additional preventive measures and better advice than a licensed hydraulic engineer.
I would not hesitate to recommend Water Stop Solutions QLD for any project.

2. StopGaps Construction Services Pty Ltd
Website: stopgaps.com.au
Areas Served: Brisbane and surrounding areas
Contact: Monday-Friday, 7:00 AM – 5:00 PM
Hours: 0434 621 266
StopGaps Construction Services Pty Ltd excels at negative side remediation for below-ground walls where exterior digging simply isn’t possible. They create engineered barriers against hydrostatic pressure right from the inside of your building.
To keep you totally in the loop, they partner with a digital platform called Industry Best Construction that lets you track real-time progress and compliance.
They deliberately over-engineer their installations, giving you incredible long-term protection against heavy sub-surface moisture.
Additionally, you won’t have to worry about random subcontractors because they hold multiple trade licenses covering joint sealing, tiling, and thermal imaging.
However, their heavy-duty approach means you might face a pricier, more complex project for a minor leak.
Clear communication and professional service
I used Stopgaps for a waterproofing job on our downstairs build-in. Iain was very open and clear about the process and was able to pass on advice even before being booked for the job. Iain was able to work in with my other trades and once on site, did a very very professional job. Great job at a great rate – Highly recommended!

Prompt and reliable waterproofing rectification work
As a result of building works adjacent to our property our zero boundary garage wall waterproofing was compromised.
We engaged Iain from Stop Gaps Construction Services to rectify and reinstate the waterproofing membrane after reading the positive reviews.
From the initial onsite meeting to completion of the job Iain was very professional and completed the project on time and on budget.
We would have no qualms in recommending Iain to anyone wanting to engage a professional waterproofing company.

3. Superior Waterproofing
Website: superiorwaterproofing.com.au/
Address: Unit 1/27 Old Pacific Highway, Yatala, QLD
Contact: 046 8760750 | [email protected]
Hours: Monday-Friday, 8:00 AM – 5:00 PM
Superior Waterproofing takes a dual-defence approach by tackling moisture issues from both the interior and exterior of your structure simultaneously.
They pinpoint specific water entry points for focused, non-invasive pressure injections instead of forcing you into a massive excavation job right away.
To restore your foundation’s strength, they strategically combine high-strength epoxy with polyurethane to handle any concrete movement. They even offer flexible after-hours scheduling to minimise disruptions for your business or family routine.
In fact, we’ve spoken directly to a Brisbane homeowner who hired them. They were thrilled with the meticulous daily cleanups that kept their living area completely spotless during the messy repairs.
The main downside is their headquarters down in Yatala. This can cause longer travel times or scheduling delays if you live in Brisbane’s northern suburbs.
Top-notch and punctual service quality
Absolutely top-notch service from start to finish! This waterproofing company is as professional as they come. From the initial inspection to the final touches, everything was handled with precision and care. The team was punctual, knowledgeable, and always respectful.
If you’re looking for reliable, professional waterproofing services, look no further. Highly recommended!

Their communication was excellent, they arrived promptly, and the quality of their work gave us real confidence. We wouldn’t hesitate to use them again and would happily recommend them to anyone needing waterproofing done.

4. Sealed Up Waterproofing Pty Ltd
Website: sealedupwaterproofing.com.au
Address: Unit 1/15 Lear Jet Dr, Caboolture
Contact: 1300 629 938 | [email protected]
Hours: Monday-Friday, 6:30 AM – 5:00 PM
Sealed Up Waterproofing Pty Ltd is a fantastic choice if you want top-tier value without compromising on structural safety. They confidently back their services with a promise to beat any quote by 10%, ensuring you never overpay for your basement repairs.
Backed by a company-wide roster of over 40 professionals, they keep more than 20 specialists dedicated strictly to the Southeast Queensland region. This is to ensure they can evaluate your leak within 24 business hours.
Moreover, they avoid tearing down your walls by using high-tech thermal cameras and acoustic sensors to find the exact source of hidden moisture. Depending on your soil conditions, they apply a mix of sheet and liquid rubber membranes to get the right seal.
Just be aware that if your existing membrane has completely failed, their technicians might physically tear out your tiles to fix the root cause. This can add some messy restoration work to your plate.
Outstanding from start to finish
Brock and Luke from Sealed Up Waterproofing did an outstanding job from start to finish. They were professional, reliable, and paid great attention to detail throughout the whole waterproofing process. The quality of workmanship was excellent, and they made sure everything was completed properly and on time.

5. S&S Remedial Services Pty Ltd
Website: ssremedial.au
Address: 6 Marlowe Road, Alberton
Contact: 07 2812 2774 | [email protected]
Hours: Available 24/7
S&S Remedial Services Pty Ltd shines by tackling active leaks with a hybrid treatment approach.
They pair polyurethane crack injections with continuous negative-side membranes across your entire wall to stop intense pressure dead in its tracks. This method saves you from the cost and headache of tearing up your driveway or garden for digging.
This team firmly believes in finding the true source of your leak rather than just slapping a quick coating over a visible damp patch. By treating construction joints directly from the inside, they seal off lateral water paths effectively.
That said, you should know that they strictly enforce a mandatory on-site inspection before giving you any budget numbers. This can slow things down if you just want a fast ballpark quote over the phone.
Fair pricing and transparent service advice
I recently engaged S&S Remedial for waterproofing work on my retaining wall and balcony, and I couldn’t be happier with the outcome. From the first interaction, the team, Sage and Shawn were friendly, transparent, and incredibly easy to deal with—no jargon, no upselling, just clear advice and a genuine commitment to doing the job right.
What truly stood out was their fair pricing. I’d received a quote from another company for $10,000. S&S completed the work—thoroughly and professionally—for just $1,000, without cutting corners. That kind of integrity is rare.

Efficient and professional post-cyclone rectification
We are very impressed by S&S Remedial Services , who waterproofed our loungeroom & storeroom after water ingress during Cyclone Alfred. The guys (John, John, Pete & Tim) are very professional, efficient, polite & friendly. They explained exactly what they were going to do and why; and they worked very well together as a team. Many thanks S&S.
