About this fill dirt

Screened fill dirt free of debris, for raising low ground and backfilling. Structural material, place it in lifts and compact as you go.

One cubic yard of fill dirt covers about 54 square feet at a 6 inch depth, and most jobs run 6 to 12 inches deep depending on how much grade you're correcting. Measure the low area, decide your target depth, and order in cubic yards rather than trying to eyeball bags. For anything over a couple hundred square feet, bulk delivery is the only practical way to get material on site.

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.

Complete Your Outdoor Project

Most fill jobs finish with a cap of topsoil once grade is set, especially anywhere lawn or planting beds will go back in. If you're building up around a foundation or pool deck, gravel or crushed stone underneath the fill can help with drainage before you backfill. Ask about pairing loads if your project needs both.

Mulch Mound Pro Tip

Fill dirt is not something you dump and walk away from. Place it in 6 to 8 inch lifts and compact each one before adding the next, especially in Reston's clay loam which already holds water and will settle unevenly if you skip compaction. Skipping this step is the number one reason people end up with a sunken patch by a foundation or patio a year or two later, right when you thought the job was done.

Mulch Mound Pro Tip

A common mistake is treating fill dirt as if it's ready to plant into. It's subsoil, screened of debris but stripped of the organic matter that makes topsoil workable. Once you've built up and compacted your grade, cap the top 4 to 6 inches with actual topsoil before seeding or planting anything. Skip this and you'll fight poor drainage and weak growth no matter how much fertilizer you add later.

Mulch Mound Pro Tip

If your project needs both fill and topsoil, order them as separate deliveries rather than trying to blend them yourself, it keeps the structural layer and the growing layer distinct and makes compaction easier to do correctly. Buying in bulk cubic yards instead of bagged material is almost always more efficient once you're past a small planter bed, particularly for foundation or pool backfill jobs that eat yardage fast.

Grading and Filling in Reston

Reston sits on clay loam that already drains slowly, so a lot of the fill work here is about correcting grade so water moves away from foundations instead of pooling against them. With elevation around 350 feet and a mix of older and newer construction in this planned community, uneven lots and settled backfill around additions are common calls. Fill dirt gets used to bring low areas up to grade before the finish material, whether that's turf, topsoil, or hardscape. It is not something you spread and plant into directly, it is the structural layer underneath everything else.

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 yard in Reston?

Yes, fill dirt is the standard material for raising low areas and correcting grade, which is common here given how much clay loam holds water. Place it in compacted 6 to 8 inch lifts rather than one deep pour, and cap with topsoil if the area will have lawn or plants. For unplanted structural fill, like against a foundation, compaction matters more than what's on top.

Answer

How many cubic yards of fill dirt do I need for a backfill job?

One cubic yard covers about 54 square feet at 6 inches deep. Measure your area in square feet, decide how deep you're filling within the typical 6 to 12 inch range, and divide accordingly. A foundation backfill or pool area often runs several cubic yards, so it helps to measure the actual void rather than guessing.

Answer

When is the best time to bring in fill dirt before winter?

Fill dirt work is driven by the project, not the season, but in Reston it helps to finish grading before the ground gets saturated ahead of first frost around October 20. Compacting fill in wet, cold clay loam is harder and less effective, so late summer or early fall gives you drier working conditions before winter sets in.

Answer

Where will the fill dirt be dropped and do I need equipment to move it?

The load is placed on your driveway or a spot you designate at checkout, so make sure there's clear truck access beforehand. Moving it from the pile to the work area typically takes a wheelbarrow and shovel for smaller jobs, or a skid steer for larger backfill and grading projects.

Answer

Is fill dirt the same as topsoil for my project?

No, fill dirt is subsoil meant for structural backfill and raising grade, it has no nutrient value and shouldn't be planted into directly. Topsoil goes on top as the growing layer once your fill is compacted to the right height. If your project involves both grading and planting, you likely need separate deliveries of each.
