Driveway Ideas
Pervious pavers commonly have joints filled with aggregate to allow water to penetrate between the pavers. Tabs are formed into each paver, providing the correct joint width and making installation easier. As with open-cell pavers, a sturdy base is required. Some ceramic pavers are actually porous themselves, allowing the water to pass through the surface directly, instead of through the gaps between. This means the gap can be narrower and doesn’t have to be refilled with aggregate as often — a common chore with other pervious paver systems. A solid base is key to minimizing heaving and cracking. You will need a 6-in. subbase of 1½-in. clean rock topped with a 4-in.base of ¾-in. clean rock, to make the driveway stable enough for cars to pass over it. The paver system goes on top of that. A polyurethane liner should be used near any foundation walls or concrete that needs to be protected from water flow-back.
