Quarry Fines, also known as 1/4" Minus or Blue Dust, is a finely crushed aggregate blend containing small rock chips and stone dust. This compactable material is ideal for creating semi-smooth, stable surfaces and is commonly used in walkways, patio sub-bases, flagstone setting, and under artificial turf.
The fine texture and angular shape allow the material to lock tightly when compacted, providing excellent stability and preventing weed growth. It is a top choice for projects requiring a clean, uniform finish and solid base structure.

Sub-base for flagstone or pavers
