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 of fill dirt covers about 54 square feet at a 6 inch depth, which is the shallow end of typical install depth. For most backfill or grade raising jobs you will want 6 to 12 inches, so figure roughly 27 to 54 square feet per yard depending on how deep you are going. Measure the low area first, decide your target depth, then order enough to place in 6 to 8 inch lifts rather than one deep pour.

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 around Seattle finish with a cap of topsoil once the fill is compacted, since fill dirt alone will not support planting. If you are leveling before hardscape, a layer of gravel or crushed rock on top of the compacted fill gives you a stable base for pavers or a shed pad. Either way, plan the finish layer before the fill goes down so you order the right depth of each.

Do not dump fill dirt in one deep layer and walk away. In a climate as wet as Seattle's, an uncompacted lift deeper than 8 inches will trap water and settle unevenly over the following winter, sometimes creating a dip right where you needed a level surface. Place it in 6 to 8 inch lifts, compact each one with a plate compactor before adding the next, and you avoid a callback next spring when the ground has dropped an inch or two.
The most common mistake we see on Seattle jobs is treating fill dirt as something you can plant into right away. It is subsoil, screened of debris, but it lacks the organic content and structure of real topsoil. Once your fill is compacted to grade, cap it with 4 to 6 inches of actual topsoil before seeding, sodding, or planting anything. Skipping that step usually means stunted grass and a yard that stays patchy no matter how much you water it.
If your project involves both raising grade and building a patio or shed pad on top, order your fill and your base gravel together so you are not paying for two separate deliveries and two trips of truck traffic across your yard. Figure the fill depth first, then the gravel base depth on top, and total both in cubic yards before you schedule. It also lets you sequence the work in one continuous stretch instead of waiting between deliveries.
Seattle's glacial till is dense and compacts hard, which is good for structural stability but means a lot of yards have poor drainage and low spots that hold water through our long wet season. Fill dirt is what you bring in to raise those areas above the water table before you build a patio, shed pad, or driveway approach. Because our wet season runs long, from fall through the March 15 last frost, uncompacted fill left exposed to rain will settle unevenly if it is not placed and packed correctly. This is a structural material, not something you plant into, so plan on capping it with topsoil for anything green.
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.
