Avista Spec Sand

Avista Spec Sand is a specific gradation of washed sand that meets Avista Utilities' requirements for backfill material around underground electrical and gas infrastructure. If you're working near or over existing Avista utilities, or installing conduit in Avista service territory, this is the material their inspectors will be looking for.

Using the right material in utility trenches isn't just a specification issue — it protects the infrastructure you're working around. Sand at the right gradation provides uniform compaction around conduit and pipe, reduces point loading, and gives future crews a clear visual indicator when they're excavating near a buried line.

Common Uses

• Utility trench bedding and backfill in Avista service areas
• Conduit protection around electrical and gas lines
• Structural backfill where clean, compactable sand is specified
• Projects in Spokane, North Idaho, and surrounding Avista service territory
