Surfaces must be engineered to withstand the test of time. Unilock pavers satisfy requirements for structural integrity, safety, environmental impact, skid resistance and weathering. The unique combination of product strength, ease of maintenance, aesthetics and reusability, result in a better life-cycle cost than other concrete products.

Our commitment to transparency through Health Product Declarations (HPDs) allows us to provide consumers with information about the contents and associated health information of our paving stones, slabs, and segmental retaining walls. By providing decision-makers with credible and useful data we hope to empower them to make better and informed decisions.
