5/8" Basalt Top Course

5/8" Basalt Top Course is a premium crushed aggregate specifically engineered for surface applications. Produced from durable basalt rock, this material is finely crushed and screened to a consistent 5/8" size, making it ideal for use as a top layer in roadways, driveways, and pathways. The basalt composition ensures excellent hardness and longevity, while the top course grading provides a well-balanced mix of fines and angular particles for superior compaction and stability.

This size and attribute combination is valued for its ability to create a smooth, firm surface that resists rutting and erosion. The angular nature of the crushed basalt interlocks tightly, reducing movement and providing a stable base for both residential and commercial projects. Common uses include final surfacing for gravel roads, driveways, parking areas, and as a base for pavers or asphalt. Pros include excellent load-bearing capacity, minimal dust, and long-lasting performance. However, due to its compacting nature, it may not be suitable for drainage applications where free water flow is required.
