Sand (Class 1, Wsdot)

Sand - WSDOT, Class 1

WSDOT Class 1 sand is a high-quality construction aggregate specifically graded to meet Washington State Department of Transportation (WSDOT) standards. This sand is carefully processed and screened to achieve a consistent particle size and cleanliness, ensuring reliable performance in demanding applications.




The Class 1 size range provides excellent compaction and stability, making it ideal for use as a base material beneath concrete slabs, asphalt pavements, and pavers. Its uniform grading also supports effective drainage, which is essential for road construction, utility bedding, and backfill projects. Because it meets strict WSDOT specifications, this sand is trusted for both residential and commercial infrastructure, including sidewalks, driveways, and highway subbases. The main advantage of WSDOT Class 1 sand is its predictable performance and compliance with regulatory requirements, though it may not be suitable for decorative or playground uses due to its engineered properties.
