Concrete sealing offers extra protection for your concrete. It holds in moisture and allows your slab to dry more effectively. Within 24 hours of laying your concrete slab, we recommend sealing it using an advanced curing chemical.

Whether it’s commercial or residential, concrete sealing can prevent cracking, strengthen surfaces, and reduce porousness. At Group One Line Marking, we are proud to provide concrete sealing throughout Sydney and NSW 7 days a week. Engineer approved, our services help you get more out of your concrete.

Highly Recommend Group 1 Linemarking!

We recently hired Group 1 Linemarking for a few of our residential strata projects, and the results exceeded our expectations. The team was punctual, professional, and clearly experienced. The line marking was crisp, precise, and done exactly to spec. Communication throughout the process was smooth, and they were flexible with scheduling, which made things a lot easier on our end. If you need reliable, high-quality line marking services, I wouldn’t hesitate to recommend Group 1. Great job!

Gerry Incollingo

The quality of work is always to a high standard. The Group One team is always professional, they apply a high standard for safety ensuring their SWMS is tailored for the job and their equipment is serviced and well maintained. I highly recommend Group One and if you use them you won't be disappointed.
