Step 4: Compact the Stone Base. Dampen the stone pack by spraying it lightly with a garden hose or watering can. Then, use a 6- or 8-inch-square hand tamper to pound the stone pack into a smooth, hard surface. Dampening the crushed stone first keeps down dust and helps with compaction. Step 5: Lay Down the Landscape Fabric

Crushed stone is available in a variety of colors and textures, depending on the quarry where it was sourced. Some common colors include white, gray, and red. Crushed stone can also be angular or rounded, depending on the shape of the stones that were used. The process of producing crushed stone typically involves several stages:
Because large stones and quarries are hard on tires, crushed stone was challenging to make and transport until heavy machinery with tracks arrived on the scene. WW2 expedited the development of this type of machinery, and crushed stone began to be used widely in construction projects in the 1940s and 1950s.
