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!

How Much Fill Dirt Do I Need?
One cubic yard of fill dirt covers about 54 square feet at a 6 inch depth, and most jobs run 6 to 12 inches depending on how much grade you are correcting. Measure the low area in square feet, decide your target depth, and that gives you the yardage. For anything deeper than about a foot, plan on building it in lifts rather than one thick pour.
What is a Yard?
A yard is approximately 27 cubic feet. As a general guideline, one yard of material can cover an area of about 100-160 square feet at a 2-3 inch depth.

One of the easiest customer service experiences I've had in a long time! Mulch Mound made it so simple. After putting it off for a while, I looked at the weather and knew I needed to get to mulching ASAP before the rain came if I didn't want to wait another week. I put my order in for the next day online and they came right at 9 AM. The employee who dropped off the mulch did a great job, putting it right on the tarp I laid out, she even made sure none of it got on the yard and double checked the truck bed to make sure it all came out. The mulch was exactly what I needed and arrived right on time.
Most fill jobs finish with a cap of topsoil once the fill is compacted, since fill dirt itself will not support grass or planting beds. If the finished area is going to be a lawn, a layer of screened topsoil on top gives roots something to actually grow in. Some jobs also call for a bit of gravel base first if the fill is going under a patio or shed pad.
Do not dump fill dirt in one deep pour if you are going past 8 inches. Spread it in lifts of 6 to 8 inches and compact each one with a plate compactor or by wetting and tamping before adding the next layer. Skip this on a pool backfill or a foundation area and you will be back out there in a year or two filling in the same low spot as it settles under its own weight.
Mulch Mound Pro Tip
The biggest mistake we see in Kings Park is people trying to seed or plant directly into fill dirt. It is subsoil, it has almost no organic matter, and grass will struggle or fail. Always cap finished fill with 4 to 6 inches of real topsoil before anything green goes in, even if the fill itself looks decent.
Mulch Mound Pro Tip
If you are filling a large low area, order fill dirt for the bulk of the depth and save topsoil for just the top layer, since topsoil costs more per yard and you do not need it below grade. This pairing gets you a stable base without paying premium material rates for the parts nobody will ever see.
Grading and Filling in Kings Park
Kings Park sits on sandy loam that drains well on its own, but that does not stop grading problems, especially on lots that were cut and filled unevenly when the neighborhood was built. Fill dirt is what people here use to correct that, raising low areas around a foundation or pool deck so water moves away from the house instead of sitting. It is not a growing medium, so anything going in on top, lawn, beds, whatever, needs a cap of real topsoil. With frost arriving late October and the ground not really thawing until into April, most fill projects on the North Shore happen in the warmer stretch when compaction actually holds.
What Clean Fill Is
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 vs Topsoil
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.
Compact in Lifts
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.

Answer
Can I use fill dirt to level my whole backyard in Kings Park?
Yes, fill dirt is the right material for raising low areas and leveling grade, but it needs to be built up in compacted lifts rather than dumped and left loose. Cap the finished grade with topsoil if you want lawn or planting there, since fill dirt alone will not support growth.
Answer
How many cubic yards do I need to fill in a low spot by my pool?
One cubic yard covers about 54 square feet at 6 inches deep. Measure the low area in square feet, multiply by your target depth in feet, and that gives you cubic yards needed. A 200 square foot area at 8 inches deep runs a little over 4 cubic yards.
Answer
When is the best time to bring in fill dirt around here?
Fill dirt is more about the job than the calendar, but with our last frost around April 7 and first frost around October 27, most people avoid working the ground while it is frozen or saturated. Late spring through fall gives you workable, compactable soil for building up grade properly.
Answer
Can the truck get the fill dirt close to where I need it?
Delivery is scheduled at checkout, and the driver will place the load as close to your work area as the driveway or yard access allows. Clear a path and mark the drop spot ahead of time, especially if you are filling near a pool or tight side yard.
Answer
Should I get fill dirt or topsoil for backfilling my foundation?
Fill dirt is the right choice for foundation backfill, since it is a structural subsoil meant to be compacted, not a growing medium. Topsoil is looser and has organic matter that breaks down over time, which can cause settling right where you need stability most. Save topsoil for the surface layer where grass or plants will grow.
