Fill Material (Class 1, Structural)

Class 1 Structural Fill Material

Class 1 structural fill material is a high-quality aggregate specifically engineered for use in load-bearing applications. This material is typically composed of well-graded, compactable soils or crushed stone, designed to meet strict standards for particle size distribution and compaction. The "Class 1" designation indicates superior performance in terms of stability and load support, making it ideal for projects where structural integrity is critical.




The structural attribute of this fill ensures excellent compaction and minimal settlement, which is essential for supporting foundations, roadways, retaining walls, and other infrastructure. Its reliable performance makes it a preferred choice for both residential and commercial construction, including building pads, embankments, and backfill around utilities. While Class 1 structural fill may require proper moisture conditioning and compaction equipment, its strength and predictability significantly reduce the risk of future settling or shifting, providing a stable base for long-term durability.
