Drain Rock, ODOT Spec, 3/4” to 1.5”
Drain rock in the 3/4" to 1.5" size range, meeting ODOT (Oregon Department of Transportation) specifications, is a durable, naturally sourced aggregate designed for optimal drainage and stability. The ODOT attribute ensures the material meets strict quality and gradation standards, making it reliable for both residential and commercial projects.
The larger 3/4" to 1.5" size allows for excellent water flow, reducing the risk of clogging and promoting efficient drainage. This makes it ideal for French drains, septic systems, retaining wall backfill, and other drainage applications. It is also commonly used as a base layer for driveways, pathways, and landscaping features where superior drainage and structural support are required. While its size and angularity provide stability and prevent compaction, it is less suitable for surfaces requiring a smooth finish. Overall, ODOT drain rock is a dependable choice for projects demanding high performance and compliance with transportation standards.Applications & Uses
