ROC / SROC (Shot Rock Overburden Crushed) is a large, rough aggregate produced from blasted or crushed overburden rock. With sizes ranging from 6" to 18"+, it is primarily used for heavy-duty applications such as erosion control, slope stabilization, construction entrances, and large fill areas. Known for its strength, durability, and load-bearing capacity, SROC is ideal for infrastructure, site development, and environmental control projects requiring maximum stability.
