Wonderful experience! They put the mulch exactly where we wanted. This mulch spread very easily and didn’t have the usual “mulch smell.” We will definitely use again!

One cubic yard covers about 54 square feet at a 6 inch depth, so a 20 by 20 foot low spot at 6 inches runs close to 4 cubic yards. For deeper fills, figure your total cubic footage and divide by 27, then round up since compaction will eat into your final grade. Most foundation backfill or pool jobs run in the 6 to 12 inch depth range per lift.

Placing an order online was so easy. Delivery was on time. When the driver realized we had a newly poured driveway they erred on the side of caution and opted not ti drive in it. The company even sent me a message explaining that call. Would recommend!
Great service. We ordered topsoil from Mulch Mound and the best experience. Thank you so much!
Most fill jobs finish with a topsoil cap once the fill is compacted, especially if lawn, beds, or anything living goes on top. If the finished area needs drainage work first, a layer of gravel or crushed rock under the fill line helps keep water from pooling against a foundation. Pair fill dirt with whatever caps the job, not with mulch or bark, which serve a different purpose entirely.

Spokane's ground freezes hard by early October and stays locked until around May, so any fill job that needs the material to settle and compact properly before you build on it should happen well before the fall freeze. Compacting frozen or half frozen fill doesn't work, it just traps ice pockets that thaw into voids come spring. If you're backfilling a foundation, aim to finish before the first week of October.
The biggest mistake on fill jobs is dumping the whole load in at once and calling it done. Fill dirt needs to go in 6 to 8 inch lifts, each one compacted before the next goes on, or the ground keeps settling for years, cracking patios and pulling gaps open along foundations. It takes longer but it's the difference between a pad that holds and one you're patching again in two summers.
Fill dirt is subsoil, not topsoil, and it has no business growing anything, so don't pay for a nutrient rich blend when you're just raising grade or backfilling a wall. Save the better material budget for a topsoil cap on top, where roots actually sit. Ordering exact yardage instead of rounding way up also keeps a job from turning into a pile of leftover dirt nobody wants.
Spokane sits at 1,843 feet with volcanic loam as the native soil, which drains fine on its own but doesn't always sit at the grade a builder needs. Fill dirt gets used here to correct that, raising low spots near foundations, leveling ground before a patio pour, or building a pad up before topsoil goes down for anything green. Because the ground freezes by early October and doesn't fully thaw until May, contractors push fill jobs hard in the shoulder seasons before frost locks up excavation work. This isn't a growing medium, it's structural material that has to be compacted right or it settles for years under a driveway or foundation.
Clean fill is screened subsoil free of debris, roots, and contaminants. It is made for volume and grade, and it compacts predictably, which is exactly what you want under slabs, in trenches, and behind walls.
Fill dirt builds the shape of the ground, topsoil grows things on top of it. Bring the grade up with fill, then cap it with 4 to 6 inches of topsoil anywhere grass or plants are going in.
Place fill in layers of 4 to 6 inches and compact each one before adding the next. Dumping the full depth at once leaves voids that settle later, and settling is the one problem fill is supposed to solve.
