Subbase in a 3/4” to 1.5” Size Range
Subbase in the 3/4" to 1.5" size range is a foundational construction aggregate commonly used beneath roads, driveways, patios, and concrete slabs. This material is typically produced by crushing and screening natural stone or recycled concrete, resulting in a mix of angular particles that interlock well for stability.
The 3/4" to 1.5" size range offers an optimal balance between compaction and drainage. Larger particles provide excellent load-bearing capacity and prevent shifting, while the range of sizes helps fill voids for a stable base. This makes it ideal for both residential and commercial projects where a strong, well-draining foundation is essential. While this subbase is not suitable for top layers due to its coarse texture, it excels as a supportive layer, reducing settling and improving longevity of overlying surfaces.Applications & Uses
