Strength and Durability: Concrete Pavers, architectural slabs and retaining walls manufactured to meet and exceed the ASTM standards.

• ASTM C 936: Standard Specification for Solid Concrete Interlocking Paving Units. (Mandatory)
• ASTM C 1372: Standard Specifications for Dry Cast Segmental Retaining Wall Units. (Mandatory)
• ASTM 1782: Standard Specification for Segmental Concrete Paving Slabs

Environmental Design: Our collection of permeable pavers can help contribute to LEED® certification. Credits can be earned in the following categories:

• Rainwater Management: LEED v4
• Heat Island Reduction – Non-Roof: LEED v4
• Materials and Resources: LEED v4

Recycled Content: Unilock products are manufactured with a varying quantity of recycled content. The option to increase recycled content during the manufacturing process is available on special order projects. Ask your Unilock Representative for more information.

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.
