Fill Material (Extra Heavy, Type A, Type B)

Fill Material - Extra Heavy, Type A, Type B

Fill material classified as Extra Heavy, Type A, and Type B is a robust construction aggregate designed for demanding structural and foundational applications. This material is typically composed of a blend of soil, sand, gravel, and sometimes crushed stone, engineered to meet strict compaction and load-bearing requirements. The "Extra Heavy" designation indicates superior density and strength, making it ideal for projects where stability and support are critical.




The Type A and Type B classifications refer to specific gradation and composition standards, ensuring consistent performance for different site conditions. Type A is often used for areas requiring maximum compaction and minimal settlement, such as under roadways, building pads, and heavy-duty parking lots. Type B is suitable for general backfill, embankments, and subgrade stabilization. The main advantage of this material is its excellent load-bearing capacity and resistance to shifting, though its density can make it more challenging to handle and compact compared to lighter fills. This makes it a preferred choice for both residential and commercial projects where long-term durability is essential.
