Limestone 1"–2" is a clean, coarse crushed stone typically sized between 1 inch and 2 inches, often referred to as drainage rock or clean base stone. Because it contains little to no fines, it allows water to pass through freely while still providing solid structural support. This makes it a dependable option for French drain systems, retaining wall backfill, foundation perimeter drainage, septic systems, and stabilization projects where strength and consistent water flow are essential.
Common applications for 1"–2" limestone
- Pipe bedding and utility trench support
- Leach fields and septic drain fields
- Perimeter foundation systems
- Structural fill in load-bearing areas
