CR6 Stone / Crusher Run
The material differs from other crushed stone and gravel products because it only includes crushed rock, but also stone dust. CR6 is carefully blended and graded to create a very low-void content. The combination of the angular pieces of stone with the fine dust particles enables CR6 to offer incredible interlocking and compaction capabilities.
