Screenings (#4, Non-Spec)

Screenings, Non-Spec, #4 Size Range

Screenings in a #4 size range with a non-spec attribute are finely crushed stone byproducts, typically produced during the process of crushing larger aggregate. These particles are smaller than traditional gravel, generally passing through a #4 sieve (about 4.75 mm), resulting in a blend of fine and coarse fragments. The "non-spec" designation means the material does not meet strict grading or quality standards, making it a versatile and cost-effective option for various construction needs.




The fine texture of #4 screenings makes them ideal for use as a leveling base beneath pavers, flagstone, or concrete slabs, where a smooth, compactable surface is required. They are also commonly used for pathways, as fill material, or for patching potholes in unpaved areas. While the non-spec nature may result in some variability in particle size and composition, this is often acceptable for general construction, landscaping, or temporary applications. However, for projects requiring precise gradation or high structural integrity, a specified aggregate may be preferable.
