Washed stone is a clean, angular crushed aggregate that has been screened and thoroughly rinsed to remove most stone dust, fines, and loose particles. The washing process leaves open spaces between the individual stones, allowing water to move freely through the material while maintaining a strong and stable aggregate structure.
Its sharp, fractured edges help the stone settle and interlock after placement, providing greater stability than naturally rounded gravel. Because it contains little to no fine material, washed stone does not compact into a dense, sealed surface. Instead, it creates a durable, free-draining layer suited to projects where both structural support and reliable water movement are important.
Washed stone is available in several sizes and gradations to accommodate different construction and landscaping needs. Smaller sizes are commonly selected for drainage systems and pipe bedding, while larger washed stone can provide dependable support for access roads, foundation backfill, erosion-control areas, and heavy-duty base installations.
Durable, versatile, and low maintenance, washed stone is widely used in residential, commercial, and civil construction. It performs especially well in areas exposed to groundwater, rainfall, or runoff, helping reduce water accumulation while providing long-term strength and dependable performance.
