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, and most Fontana jobs run 6 to 12 inches depending on how much grade needs to come up. Measure the low area in square feet, decide your target depth, and figure yards from there rather than guessing. Because it is sold by the cubic yard and weighs in around 1.3 tons per yard, oversizing an order gets expensive fast in both cost and what your driveway or lot can handle.

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 dirt jobs in Fontana get capped with a few inches of topsoil once the grade is set, especially if grass or planting beds go on top. Some pool and foundation jobs also pair fill with a base rock layer for extra stability on clay ground. Neither is required, it depends on what the finished surface needs to do.
Service area
On Fontana's clay, do not dump fill dirt in one deep pour and walk away. Build it in 6 to 8 inch lifts and compact each lift before adding the next, with a plate compactor for small areas or a roller for bigger backfill jobs. Skip this and the ground keeps settling for a year or more, showing up as a sunken patch near a foundation or pool deck long after the job looked finished.
A common mistake is planting or seeding straight into fill dirt. It is subsoil, not a growing medium, and it lacks the organic content turf or beds need. Always cap finished fill with several inches of real topsoil before anything is expected to grow, especially with Fontana's dry stretches between the December and January frost dates putting extra stress on new plantings.
If you are backfilling around a pool or foundation, order fill dirt for the bulk of the depth and save topsoil for just the top layer, since topsoil costs more per yard and does nothing structurally that fill dirt does not already do better. This layering approach keeps material cost proportional to what each layer actually needs to accomplish.
Fontana sits on heavy clay that already drains slowly, so when a yard has a low pocket it tends to stay wet and soft instead of shedding water. Fill dirt raises that grade so water moves off the lot instead of collecting near a foundation or slab. It is also the standard choice around here for building up ground before a pool deck or patio pour, since clay subgrade needs a stable base layer first. This is structural material, so it does the heavy lifting before topsoil or turf ever goes in.
Fill dirt is inorganic subsoil sold for volume and grade, not for growing. Small rocks and bits of stick or root are normal in the mix. 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.
