The fine print
Grasstone™ I, made with an open-void, interlocking lattice design, creates a flat surface for intermittent paver applications. The open void allows for on-site infiltration of storm water and vegetation. Designs can use topsoil and grass or aggregates in the grid openings depending upon desired effect. This concrete grid paver reinforces grassy areas that are subject to wheeled or vehicular traffic. Typically an area that undergoes repeat vehicular traffic will become so compacted that the permeability of the soil structure is inhibited to the point that the grass is unable to survive. Because the Grasstone™ I paver enables traffic to drive through areas designated as greenspace, it is a good product for vehicular paths that maintain vegetation such as emergency access routes and overflow parking.
