Fill Materials
We deliver every gradeClay
Clay is dirt made of extremely fine mineral particles, small enough that the grains cling to each other instead of rolling apart. When it's wet, it turns plastic and easy to shape. When it dries out or gets packed down, it hardens and holds. That's what makes clay useful as fill: water doesn't soak through it easily, and it stays put once it's compacted.
Clay comes out of the ground in a lot of different colors and mixes, so what you get depends on what's in the pit closest to you. Some of it's nearly pure and heavy with moisture. Some shows up cut with sand or silt and drains a little faster. It's usually one of the cheaper fills by the yard because it's dug out of local pits. Figure a load of clay weighs about 1.3 to 1.5 tons per cubic yard once it's wet or compacted in place.
What people use it for
How to choose within clay
Under something heavy
Use structural fill — angular, clean, compactable — under a slab, driveway, or foundation.
Just raising grade
General fill works — it's cheap dirt that levels a yard, patches a hole, or brings a low spot up to grade.
Never the top layer
Fill goes under, not on. Topsoil or a wear layer goes on top — fill won't grow anything and it won't hold up traffic.
