Aggregate

County Materials supplies a full range of aggregates, sands, and soils for construction, site development, infrastructure, and landscape applications. Our materials are produced through controlled quarrying, crushing, and screening to deliver consistent gradation, dependable performance, and specification compliance. Contractors, builders, and developers rely on our bulk aggregates for road base, concrete production, drainage, and erosion control, as well as specialty sands and soils for grading and backfill. For residential and commercial landscapes, we also offer decorative aggregate that enhances pathways, tree and shrub beds, water features, and outdoor spaces—combining durability with visual appeal. With regional production capabilities and reliable dispatch support, County Materials helps keep projects moving on schedule while delivering long‑lasting results.
