Ordered Dirt. Received Dirt. Would Buy Again.

One cubic yard of fill dirt covers about 54 square feet at a 6 inch depth, and most structural fill jobs run 6 to 12 inches depending on how much grade you need to make up. Measure the low area in square feet, decide your depth based on how much you are raising the ground, and order in cubic yards from there. For anything over a foot of fill, plan on building it in lifts rather than one deep pour.

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.

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!

Complete Your Outdoor Project

Most fill jobs get capped with a few inches of topsoil once the grade is set, especially if grass or beds are going back in on top. If you are backfilling around a foundation or a removed structure, a layer of gravel underneath for drainage is common before the fill goes in. Mulch or topsoil orders are easy to add once the structural work is done.

Mulch Mound Pro Tip

St. Louis clay does not forgive shortcuts on compaction. Place fill dirt in lifts of 6 to 8 inches and compact each layer before adding the next, whether you are using a hand tamper or a plate compactor for larger areas. Skipping this step and filling deep in one pass is the number one reason people end up with a sunken yard or a cracked patio slab a year or two later, especially over pool backfills where the cavity walls can trap water against uncompacted fill.

Mulch Mound Pro Tip

Fill dirt is not a growing medium, and trying to plant directly into it around here usually fails because the clay-heavy subsoil compacts too tight for roots to push through. Once your grade is set and compacted, cap it with 4 to 6 inches of actual topsoil before seeding or laying sod. This is especially important on foundation backfills where drainage away from the house matters as much as the grade itself.

Mulch Mound Pro Tip

If you are backfilling a large low area or an old pool, break the job into fill dirt for bulk volume and a thinner topsoil cap for anything that needs to grow, rather than paying for topsoil depth you do not need structurally. Pairing a gravel base under the fill in wet-draining areas of the yard also reduces how often you will need to come back and re-grade after a wet St. Louis spring.

Grading and Filling in St. Louis

St. Louis sits on heavy clay that compacts hard when wet and cracks when it dries out, which means a lot of older homes near downtown and the Hill have settled foundations and low yards that pool water after storms. Fill dirt is the structural fix for that, used to raise grade around a foundation or backfill a removed pool before anything else goes in. Because the clay base here does not drain fast, getting the grade right with compacted fill matters more than it would in sandier soil. This is not topsoil and it will not support planting on its own, it is the base layer underneath.

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.

Frequently Asked Questions

Click a question to see the answer

Answer

Is fill dirt the same as topsoil for my yard project in St. Louis?

No, fill dirt is subsoil meant to raise grade or backfill, it does not have the organic content to grow anything well. If you are leveling a low spot and then planting grass or a garden bed, you need fill dirt for the base and a topsoil cap on top. Using fill dirt alone under grass usually leads to poor growth because the clay-heavy subsoil compacts too dense for roots.

Answer

How many cubic yards of fill dirt do I need for my project?

One cubic yard covers about 54 square feet at 6 inches deep, so measure your area in square feet and multiply by your target depth in feet to get cubic yards. Most structural fill jobs run 6 to 12 inches, and pool backfills or deep low spots often need more once you account for compaction. Order slightly extra since fill settles as it is placed.

Answer

When is the right time to bring in fill dirt around St. Louis?

Fill dirt jobs are driven by the project, not the season, so there is no single best month. That said, working the clay when it is not saturated makes compaction easier, so avoiding the wettest stretches of spring can save you frustration. Aim to finish grading before your first frost in late October if you plan to seed or sod on top the same season.

Answer

Where will the delivery truck place the fill dirt on my property?

You choose the drop location when you schedule, and the truck places the load there directly. Make sure the path to that spot is clear and wide enough for a delivery truck, and let us know about any tight access, low branches, or soft ground so we can plan the drop accordingly.

Answer

Should I get fill dirt or topsoil for leveling a low spot in my yard?

If the low spot is more than a few inches deep, use fill dirt for the bulk of it and cap the top few inches with topsoil where grass or plants will go. Using topsoil alone for deep fill wastes material and does not compact the way structural fill does, which matters in St. Louis clay where poor compaction leads to future settling.
