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 Guarantee has been a part of our commitment for the past 35 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, slabs and retaining wall units to the original purchaser of the product for residential use.
