Product Overview
#9 Coarse Aggregate
Smaller crushed limestone used for driveway surface layers, backfill, and general aggregate needs. Its size makes it easier to spread and shape, providing a more refined surface appearance when placed over a stable base. Performance depends on base stability, edging, and traffic patterns.
Why This Material Works
The smaller gradation creates a smoother surface while maintaining adequate drainage. When properly installed, it offers a clean, functional finish.
Common Applications
- Driveway surface stone
- Backfill
- General construction use
Material Characteristics
- Smaller size for smoother surface behavior
- Easy to spread and shape
- Performs best over a stable base
Planning Notes
Best results are achieved with proper base preparation and edge containment. Occasional maintenance may be needed depending on traffic levels.
