Concrete Sealing Services

Concrete Sealing

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.
