1-1/2" Recycled Concrete Rock
Our 1½" recycled concrete rock is a medium-sized screened aggregate sized 1½" × ¾", produced by crushing and screening recycled concrete from demolition projects across the Front Range. The tight size range and minimal fines content make it an excellent free-draining material wherever water management is the priority.
The angular, fractured faces of recycled concrete provide good interlock and stability in drainage beds and trench applications. Near-zero fines (1% passing #200) means water moves freely through the aggregate without clogging.
Common applications: storm sewer and sanitary pipe bedding, French drains, perimeter foundation drains, retaining wall drainage cores, utility trench backfill, and erosion control.
