Where to Use Them
Permeable pavers can guard against flood damage by allowing rainwater to infiltrate the ground. "Within driveways, we often use block pavers with a significant material thickness. The added thickness is essential for areas trafficked by cars and trucks. These blocks can be made of granite Belgian block cobbles or a prefabricated concrete aggregate block. Blocks are set on a gravel base, spaced evenly, and set with open joints that are then swept with a sand mixture to allow stormwater to percolate through," explains landscape designer Douglas Clark. Think about putting them wherever water tends to collect. HECKER GUTHRIE If you don't have a driveway but love the idea of a concrete-meets-greenery hybrid, beauty a space by the patio. This outdoor space by Melbourne, Australia–based Hecker Guthrie proves that grass pavers can do more than driveways. They also make great terraces and walkways.
