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, so a small low spot might only need a yard or two while backfilling around a foundation or pool wall can run into double digits fast. Measure the area you are raising in square feet, decide whether you need 6 or 12 inches, and scale from there since fill is sold and delivered by the cubic yard. Rough grading projects usually run wider and shallower than backfill jobs, so measure the actual footprint rather than guessing.

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 cap of topsoil once the grade is set, especially if turf or plantings are going back in over the filled area. Some customers also order crushed stone for a compacted base under sheds, patios, or gravel driveways where drainage matters more than growing anything. Think of fill dirt as the structural layer, then decide what needs to sit on top of it.

Compact fill dirt in 6 to 8 inch lifts, not one big dumped pile. Around Onalaska's silt loam, uncompacted fill can settle unevenly for a full year or more as it works through freeze thaw cycles each winter, leaving dips right where you didn't want them. A hand tamper works for small spots, but rent a plate compactor for anything backfilling a foundation or larger pool area.
The most common mistake is treating fill dirt like it will grow grass. It is subsoil, screened of debris but stripped of the organic matter that makes silt loam productive here. Always cap finished grade with 4 to 6 inches of real topsoil before seeding or sodding, or you will fight bare patches and poor root growth for seasons afterward.
Order fill dirt for the bulk of the depth you need and save topsoil for just the top few inches, since topsoil costs more and does nothing extra once it is buried under 8 inches of fill. This layering approach, cheap structural fill below, quality growing medium above, is how most graded lots and backfilled foundations around Onalaska actually get built.
Onalaska's native silt loam holds water well, which is great for growing things but means low areas near the lake and river flats can stay soft and spongy long after rain. Fill dirt gives you a compactable base to build up those areas so water sheds away from foundations, sheds, and pool decks instead of sitting there. Because the ground here has a habit of settling once it thaws each spring after our zone 5a winters, fill placed and compacted correctly the first time saves you from redoing the job. It is a structural fix, not a planting medium, so pair it with topsoil once the grade is set.
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.
