Material Descriptions
3/4" Crushed Stone
— · Zero Fines · CSI 33 05 17
Single-size clean crushed stone with approximately 40% air void content. Zero fines means unrestricted lateral drainage flow — the standard material for perforated underdrain pipe bedding, utility trench backfill, and infiltration systems. Also used as concrete coarse aggregate where clean angular stone is required.
1-1/2" Crushed Stone
— · Zero Fines · CSI 33 46 13
Coarse clean stone with approximately 45% air voids — highest drainage capacity in our inventory. Specified by Maine DEP for septic leach field aggregate and by engineers for foundation drainage blankets and subsurface stormwater infiltration beds. Angular fractures interlock to resist displacement under loading.
4" Rip Rap
ME DOT § 703.19 · Light Erosion Control
Smaller-class rip rap for light-duty erosion control applications. The interlocking angular stone armor protects slopes and channel bottoms against surface water runoff. Used for ditch lining, culvert outlets, slope toe protection, and low-energy channel lining where large stone is not required.
8–10" Rip Rap
ME DOT § 703.19 · Heavy Erosion Control
Large-format angular stone armor for high-energy erosion environments. The mass and irregular shape of 8–10" stone resists displacement under significant hydraulic force. Standard application for lake and stream shoreline stabilization, bridge abutment protection, and steep slope armoring in Maine.
