Our Washed #1 A’s are clean, crushed stone that has been thoroughly washed to remove dust and fines, resulting in an aggregate with excellent drainage and consistent performance. The angular shape allows the stone to lock together while still permitting proper water flow.

Commonly used for drainage systems, pipe bedding, foundations, utility trenches, and base preparation, washed #1 A stone is a trusted material for both residential and commercial applications. Its clean composition makes it ideal for projects where drainage and structural stability are critical.

Whether you’re managing water flow, preparing a solid base, or completing a construction project, Sensenig’s Washed #1 A’s deliver dependable performance and professional results.
