#789 granite, also known as #789 stone, granite screenings or compactable granite fines, is a finely graded crushed aggregate typically ranging from approximately 1/4 inch and 1/2 inch its often a blend of #7, #8 and #9 stone. Its balanced blend of angular granite chips and fines allows the material to spread evenly and compact into a smooth, firm, and stable surface.
The larger particles provide strength and surface structure, while the finer material fills the spaces between the stone and helps the blend lock together under pressure. When properly graded and mechanically compacted, #789 granite creates a durable surface that resists shifting, rutting, and erosion while supporting controlled water movement.
#789 granite is popular for residential, commercial, and landscape projects because it combines the hardness and wear resistance of granite with dependable compaction and a clean natural finish. It performs especially well as a surface or finishing layer over a prepared base where a smoother texture and long-term stability are important. Exact gradation may vary by quarry and regional specification.
Common Applications of #789 Granite
- Driveway and access-road surfacing
- Gravel road top layers and resurfacing
- Walkways and compacted landscape pathways
- Patio and hardscape base preparation
- Parking pads and light-traffic areas
- Surface grading and low-area correction
- Courtyard and garden path construction
- Finishing layers over larger aggregate bases
