Professional Ground Treatment
for Stability & Support
Concrete joints are critical for slab movement and durability. When joints fail, water and contaminants enter the system leading to costly damage. WS Remedial Group restores concrete performance with tailored sealing and repair solutions across NSW.
Why it matters
Damaged joints can cause:
- Erosion of the subgrade
- Loss of load transfer between slabs
- Spalling and chipping of slab edges
- Moisture ingress and structural deterioration
- Higher cleaning and maintenance costs
What we service:
Our joint sealing and refurbishment service restores the function and appearance of joints, so your concrete performs as designed. Many projects also involve edge repairs to prevent further breakdown. We select the right sealant system for your site whether it’s:
- High load industrial hardstands
- Commercial car parks and workshops
- External pavements and driveways exposed to weather
Who we service
- Industrial and Commercial: warehouses, factories, workshops, car parks, aprons
- Infrastructure: bridge decks, plaza areas, public spaces
- Residential: driveways, patios, pool surrounds, garage floors

I have worked closely with Dan and Kelly on a few projects in Darwin. Dan and Kelly have been a great pleasure and very professional to work with. I highly recommend WS Remedial for any water stop solutions, they do know their stuff.

Had a really positive experience with WS Remedial. The team was friendly, easy to communicate with and clearly knew what they were doing. They explained things in a straightforward way and were professional throughout. Would happily recommend them.

On-site crew are easy to work with, team gets the job done, no dramas and very professional in the work they do.
And although it was almost Christmas when I asked for their services, Kelly made it all happen smoothly and was terrific to work with.
Thanks

The professionalism of these guys is off the charts. I have a building that has water damage. Their people came in, gave a full comprehensive review - then told me the most cost effective way to fix it.

Waterstop Solutions recently conducted repairs works on our community centre. We found the pre works checks and logistics by Kelly excellent and responsive to our needs. Dudley and his sidekicks conducted themselves extremely professionally, kept us informed and followed our sign-in protocols to the letter. I would not hesitate to recommend this excellent business.

Great service from Angus at assessment and quotation, through to Mariette to organise the booking, and finished by Dudley and Tyson completing the job. Would certainly recommend WaterStop for their professional manner and quality workmanship.

My wife and I have been delighted with the professional services provided by the Waterstop team including Angus, Tom and Ash. They took the time to understand and diagnose the water problem at our residence, and problem-solved to come up with the optimum solution. Time will tell but we are confident that the grinding, injections and vapour layer will solve the issue. We are impressed with how they related to us and the care they took. Highly recommended.

Water stop Solutions is my one stop shop to fix difficult water leaks. Having managed apartment buildings for 20 years I’ve had my fair share of water leaks. WaterStop solutions are my first call. I was lucky enough to get Mick on the job this morning. He showed up on time, reviewed what needed to be done and got into it. Job site was left, clean and tidy. I appreciate their good work and you will too

We had a frustrating issue with water leaking into our garage, and after struggling to find a proper fix, Waterstop came through. The team was professional and reliable, with special mention to Brandon, who kept us updated throughout the entire project and made the whole process easier. The quality of work was excellent. Highly recommend!

Dudley and Anthony did a great job repairing and re-tiling our leaking balcony over a bedroom. Dudley and the team at Waterstop were flexible and worked with us and our contractors to implement sound solutions to significant problems found with the slab when the old tiles came up so that a robust waterproof solution could be put in place.

Exceptional service from Waterstop Solutions!
I was dealing with concrete dusting and high moisture issues in my garage and initially considered solutions recommended by others. However, after reaching out to Waterstop Solutions, they quickly identified that some of those options could actually worsen the problem over time.
Their expertise and honest advice helped me choose a cost-effective, non-invasive treatment that worked perfectly. The team was professional, knowledgeable, and efficient, making the whole process seamless.
A big thanks to Josh and the team at Waterstop Solutions for their outstanding work! Highly recommend their services.
