Unilock’s Eco-Optiloc paver is the permeable version of the high-performance, heavy-duty Optiloc® paver system, designed to provide exceptional durability and functionality for vehicular applications. Featuring special spacer bars that create a 12mm gap between units, Eco-Optiloc™ pavers ensure excellent infiltration rates when installed on an open graded base with fine stone chip between the joints. This heavy-duty industrial paver utilizes L-shaped, tri-axis locking properties, making it one of the best solutions for permeable vehicular pavements. Eco-Optiloc™ can be laid mechanically, making it ideal for large-scale commercial projects, with special order colors and textures available to meet specific design requirements. Color availability varies by location.
