#4 gravel 1.5 inch to 2.5 inch is a large, durable aggregate commonly used for heavy-duty drainage and structural support. Typically ranging from 1.5 inches to 2.5 inches, this coarse stone allows water to flow freely, making it ideal for applications where clogging must be prevented. Its size and strength also provide excellent load-bearing capacity in demanding construction environments.
Because of its open structure, #4 gravel performs well in areas that require stability without trapping water, especially in base and erosion control applications.
Common applications for #4 gravel (1.5"–2.5")
- Drainage systems and pipe bedding
- Driveway and road base support
- Parking lot sub-base
- Erosion control and washout protection
