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.

Online ordering was really simple and I liked the transparent pricing.

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 deep depending on how much grade you are correcting. For a small backyard low spot, figure 2 to 4 cubic yards, while a foundation backfill or larger grading project around a Cambridge triple decker lot can run into double digits. Measure the low area in square feet and divide by 54 to get a starting yard count at 6 inches, then adjust for depth.

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

Fill dirt is a base layer, not a finish, so most jobs cap it with a few inches of topsoil once the grade is set and compacted. If the area borders a patio or walkway, crushed stone underneath the fill can help with drainage in Cambridge's heavier clay-leaning silt loam. Mulch comes in later once whatever you plant on top of the topsoil is in the ground.

Mulch Mound Pro Tip

Do not dump fill dirt in one deep pour. Cambridge's silt loam base already holds water, and a thick uncompacted layer will trap moisture underneath and settle unevenly for years, sometimes cracking a patio or slab poured on top too soon. Place it in 6 to 8 inch lifts, compact each one with a plate compactor or hand tamper before adding the next, and only cap with topsoil once the final lift is firm and stable underfoot.

Mulch Mound Pro Tip

The most common mistake we see on backfill jobs here is skipping compaction near foundation walls because it is slow going with a shovel and tamper in a tight space. That uncompacted fill settles after the first freeze thaw cycle each winter, pulling soil away from the foundation and creating a trench that collects water. Take the extra time to compact in thin lifts right against the wall, even if it means renting a smaller compactor.

Mulch Mound Pro Tip

If you are raising a large area, order fill dirt for the bulk of the depth and save topsoil for just the top few inches where roots actually need it. Topsoil costs more per yard, so using it only where something will grow keeps the project efficient without sacrificing results, especially on bigger grading jobs around Cambridge's older lots where several yards of fill get used just to level things out.

Grading and Filling in Cambridge

Cambridge sits low and flat at around 40 feet elevation, and a lot of older lots near the Charles have drainage issues where water pools against foundations or in backyards after a hard rain. The native silt loam holds moisture well, which is good for planting but bad when you need stable, buildable ground. Fill dirt gives you a structural base to raise those low areas or bring a yard up to grade before construction, additions, or a new patio. With frost reaching down through winter here, fill placed and compacted properly resists the heaving that loose or wet soil is prone to.

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

Can I plant grass or a garden directly in fill dirt?

No, fill dirt is a structural subsoil meant for raising grade and backfilling, not a growing medium. It lacks the organic matter and nutrients plants need. Once your fill is placed and compacted to the grade you want, cap it with a few inches of topsoil before seeding grass or planting anything.

Answer

How many cubic yards do I need to raise a low spot in my backyard?

One cubic yard covers about 54 square feet at 6 inches deep. Measure the low area's square footage, divide by 54, then multiply by however many 6 inch layers you need for your total depth. A typical backyard low spot of 200 square feet at 6 inches needs roughly 4 cubic yards.

Answer

When is the best time to bring in fill dirt in Cambridge?

Fill dirt work is driven by your project timeline, not the season, since it is not a planting material. That said, working before the ground freezes in mid October or after it thaws around late April makes compaction easier, since frozen or waterlogged silt loam is harder to compact properly.

Answer

Will the delivery truck be able to access my property?

Most Cambridge deliveries go straight into a driveway or curbside where our truck can dump the load directly. Narrow streets, tight triple decker lots, or limited parking can restrict where the truck parks, so let us know about access constraints and we will work out the best drop spot with you.

Answer

Should I get fill dirt or topsoil for my grading project?

Use fill dirt for the bulk of any grading or backfill work where you are raising elevation, since it is denser and cheaper per yard than topsoil. Reserve topsoil for the top 4 to 6 inches only, where grass or plants will actually root. Combining both gets you a stable base and a growable surface.
