Open-jointed paving blocks are solid units shaped or placed to leave open spaces in the joints between adjacent units. The blocks are manufactured from concrete or clay, or cut from natural stone or wood. The joints are filled with porous aggregate or vegetated soil, or left vacant. Together, the blocks and joints form a composite surface that can be porous and permeable while bearing traffic loads through the structure.
