Turf block and permeable joint pavers (pavers) are used for areas with light vehicle loading, such as driveways, low-volume streets, street shoulders, and parking stalls. The terms turf block and permeable joint pavers describe systems comprised of a load-bearing, durable surface together with a pervious soil that temporarily stores water, with overflow conveyed to an outlet. The turf block surface is constructed of impermeable blocks separated by spaces and joints, filled with soil and planted with turf, through which the water can drain. Alternately, the spaces and joints of turf block may be filled with gravel.
