2A gray modified stone is a great choice to create drainage beds and level out areas for driveways and walkways as well as providing foundations for brick or cement block. 2A modified stone is different than natural gravel in that 2A gray modified stone starts as large rock and is mechanically crushed to produce the product – the reason it’s designated as “modified”. 2A modified stone is best used in places where aesthetics are not a priority, and adequate drainage and compaction is desired. If you’re looking for decorative stone, you can find various varieties on our bulk materials page here. We sell 2A red modified stone as well – you can find that here. Stone Depot stocks a large variety of stone, soil, sand, and mulch products for your landscaping, hardscaping, and other construction needs.
