In a driveway or pad build, #4 Crushed Stone belongs early in the aggregate work, where a heavy open course is needed before the tighter material above. Its crushed shape leaves broad spaces for water movement and resists shifting when traffic bears on the assembly. It is not meant to create the compacted feel of a finer travel course.
Flat prairie clay often drains slowly, while freeze and thaw can keep moisture affecting traffic areas through an Illinois winter. Set this material below the finished course to help keep water from remaining in the supporting aggregate. This matters on farm lanes, shed pads, and garage approaches during wet periods. It is also appropriate for drainage through prairie clay and erosion control on slopes or ditches. Where the top course needs a tighter finish, use a finer base material above #4 Crushed Stone.

Common Uses
Load-Bearing Layer
Use below driveways and regularly traveled areas to support a stable base over prairie clay.
Erosion Control
Place larger rock along slopes, ditches, and channels to limit washout.
High-Volume Drainage
Wide openings allow substantial water flow to move through quickly.
Gabion Fill
Its size works for gabion baskets and retaining structures.
Why Choose #4 Crushed Stone
Strong Drainage
The larger openings accommodate heavy water flow.
Load Bearing
Helps limit movement beneath vehicles and equipment.
Erosion Resistant
On slopes, the weight and angular shape help the stone stay put.
Durable Base
