We deliver itFill Material (4″ Minus, Engineered)
Engineered fill material in a 4" minus size range is a specially processed aggregate blend designed for structural backfill and site grading. "4" minus" means the material contains particles up to 4 inches in diameter, along with smaller sizes down to fines, ensuring optimal compaction and stability. As an engineered product, it is manufactured to meet specific gradation and performance standards, reducing the risk of settling and providing reliable load-bearing support.

Fill Dirt
Fill dirt is unscreened subsoil sold in bulk to raise grade or backfill a hole — cheap and heavy, and never the layer plants root into.

Cheap, unwashed sand with a little silt in it, used to fill low spots and pack around foundations — not the clean stuff you'd bed pavers on.
