Fill Dirt in Gaithersburg, MD

Fill-dirt is soil used to raise or level ground, usually low in organic matter and not intended for planting. In Gaithersburg it is commonly used to build grades, raise yards after excavation, or replace unsuitable native clay before landscaping; it is not a substitute for structural base material like crushed stone under driveways.

In the Washington-Arlington metro area, delivered fill-dirt for Gaithersburg generally runs in the neighborhood of $20 to $40 per ton depending on availability, haul distance, and order size.

Small yard projects typically do not need permits, but larger grading, significant elevation changes, or deposits of large quantities may require permits from Montgomery County Department of Permitting Services. Always check with Montgomery County DPS and your local municipality before major earthwork; if you are unsure, contact our team and we can point you to the right local office.

A good rule: 1 cubic yard of fill-dirt is about 1.2 to 1.4 tons (use 1.3 tons as a practical average). To calculate: cubic yards = (square feet x depth in inches) / 324, then multiply cubic yards by 1.3 to get tons; for example, 1 inch over 1,000 sq ft is roughly 4 tons.

Because the Gaithersburg area has clay-rich soils and seasonal freeze-thaw, plain fill-dirt that retains water may settle, heave, or shift unless placed and compacted correctly with good drainage. For areas subject to frost or structural loads, contractors will typically use free-draining granular materials or engineered fill and ensure proper compaction and drainage rather than relying on straight fill-dirt alone.

Local contractors in Gaithersburg commonly place fill-dirt in lifts of about 4 to 8 inches loose and compact each lift with plate compactors, vibratory rollers, or tamping equipment. For general landscaping aim for 90% of standard compaction; for structural pads or near foundations, engineers often specify 95% or more and may require testing. Equipment used includes skid steers and excavators for placing, and plate compactors or small rollers for compaction.

Fill-dirt can be used to raise grade under yard areas, but it is not a good surface or structural base for driveways or patios. In Gaithersburg you should place a properly compacted granular base (crushed stone or 21A) for driveways and patios, with fill-dirt only used where plan specs call for non-structural grade adjustments.

Rates vary by project size, access, and equipment needs: typical residential labor/equipment rates in the Gaithersburg area run roughly $75 to $150 per hour for machines with operators, while small jobs or handwork can be $50 to $100 per hour for labor. Some contractors price spreading and compacting by the job; for a modest 10-20 ton delivery expect contractor fees in the low hundreds to perhaps $500–$1,200 depending on complexity—get local written estimates for accuracy.

Most settling happens during the first 6 to 12 months, especially after seasonal rain and freeze-thaw cycles, so expect to top up low spots after the first winter. For lawns, seed and erosion control help stabilize new fill; for access or load-bearing areas, inspect after heavy weather and consult your contractor about additional compaction or adding engineered material if needed.

Yes. Winter freezes, heavy rains, and muddy access in Montgomery County can limit truck access or require extra fees for protection, longer hauls, or delays. Hello Gravel shows available delivery windows and any regional surcharges during checkout; drivers will also assess site access on arrival and may decline tailgate spreading if conditions are unsafe.
