Lifetime Guarantee

Our commitment of quality and strength.

Unilock was the first concrete paver manufacturer in North America to offer a Lifetime Guarantee, and we have continued to back it up to make sure you’re completely satisfied with our product. That’s quite the commitment since we have over 10 billion stones on the ground! We can do this because our product is better and stronger. In fact, our internal standards of manufacturing far exceed industry standards set by ASTM, CSA and European organizations. Our Lifetime Warranty has been a part of our commitment for the past 50 years. We stand behind every stone we make – just ask our customers.

Our Warranty

Unilock provides a Transferable Lifetime Guarantee on the structural integrity of our paving stones and retaining wall units for residential use. Any materials installed and maintained to our guidelines, and subject to normal wear, that prove defective, will be replaced without cost. Color matching cannot be guaranteed and replacement labor is not included. Registration is required and must be complete within 60 days of your dated proof of purchase.
