Kapstone crusher's dust sand is the best quality of sand available. Water from heavy rains will not seep under the paving stones as the crusher dust is not porous. This can reduce the risk of shifting and damaging paving stones on driveways and pavers, prevent minerals from leaching into nearby soil, and reduce water logging. It serves as an ideal layer under synthetic turf, driveway bases, retaining walls and driveways, as well as a decorative feature in landscaping. It can be used as a substitute for sand in making concrete products and admixtures.
