HPB (High Performance Bedding)
The best choice for patio and walkway bases. 1/4" angular chips provide excellent drainage and lock together for a stable base. Won't heave in freeze-thaw cycles.
Granular A / Crusher Run
Ideal for driveways and heavy-use areas. Contains fines that compact to create a solid, stable surface. Can handle vehicle traffic.
Clear Stone
Clean stone with no fines, perfect for drainage applications. Allows water to flow freely through the material. Great for French drains and weeping tile.
