Granular Subbase
Granular subbase is a foundational construction aggregate composed of crushed stone, gravel, or sand, processed to create a stable, free-draining layer beneath roads, driveways, and pavements. The "granular" attribute means the material consists of loose, unbound particles, allowing for excellent compaction and load distribution.
This material is essential for creating a strong, stable base that resists shifting and settling over time. Its granular nature promotes effective drainage, reducing the risk of water accumulation and frost heave. Commonly used in both residential and commercial projects, granular subbase is ideal for road construction, parking lots, patios, and under concrete slabs. While it offers superior drainage and ease of installation, it may require proper edge restraint to prevent lateral movement. Overall, granular subbase is a reliable choice for long-lasting, well-drained foundations.Applications & Uses
