Molded from 100% recycled rubber, Ultimate I Pavers are the smart solution for demanding outdoor applications. Ultimate's interlocking rubber pavers are available in two thicknesses (0.875"/22.23mm or 1.75"/44.45mm) and three colors - terra cotta red, forest green or jet black. Extremely durable and long lasting, Ultimate I Pavers provide excellent cushioning for both humans and animals alike. Rubber pavers are slip resistant (in wet or dry conditions) and water permeable - meaning they shed water quickly and eliminate standing water. Ultimate I Pavers will not crack or chip; have excellent impact resistance & shock absorbing properties; and are impervious to ice or extreme temperature changes.
