Crushed Stone, Sand and Gravel in Gaithersburg, MD

Maryland Rock Supply handles gravel and aggregate delivery in Gaithersburg, MD for two kinds of buyers: crews grading lots and homeowners fixing a yard. Contractors here order CR-6 by the ton and know what the number means. Homeowners usually start with a photo and a question about topsoil. Both get the same answer: match the material to the ground.

Montgomery County ground is loam and silt loam over schist and gneiss, often flaky with mica. That shapes what you put on top of it.

Materials for Gaithersburg Projects

Most of the work we fill in Gaithersburg is grading and planting, so soil and fill lead the list. Rebuilding grade after construction is the usual starting point, and every layer above it depends on getting that right.

Screened Top Soil goes down for lawn and bed prep and for rebuilding grade after a build. Order it after fill has been placed and packed, not before. Garden Soil is the raised bed and planting mix, blended for beds rather than for spreading over a whole lawn. Fill Dirt raises grade, backfills and takes out low spots before base or topsoil goes down. Shredded Mulch finishes the beds and tree rings and holds moisture through hot, humid summers.

Below the soil, the base. CR-6 is the standard Maryland base for driveways, parking pads, shed bases and paver sub-base, a compacting blend of crushed stone down to dust. Crusher Run does the same job where a binding blend is wanted, and it is listed as a separate product from CR-6. Bedding under pavers and slabs is usually Washed Sand, with Screenings for paver joints and flagstone bedding; most yards around here still call that stone dust. Driveway Gravel surfaces an existing drive or tops a compacted base.

Ground and Conditions in Gaithersburg

Start with where the water goes. Gaithersburg sits on rolling slopes that shed storm runoff fast toward stream valleys, and the silty soil turns soft and hard to compact once it is saturated. A drive needs a crown, a ditch or a drain wherever water collects, or the base under it will not hold.

Saturation is the reason base depth matters more than material choice in some yards. CR-6 placed thin over wet silt will rut, and regular freeze-thaw cycles heave and rut drives built on a thin base. Frost depth runs about 30 inches in most county codes across this zone, so footing depth is a design question, not a guess.

Erosion is the other half. Summer thunderstorms and tropical storm rain scour stream banks, and bare sloping ground washes during grading. Put RipRap at culvert outlets and on exposed banks, and #57 Stone in French drains and driveway topping where water needs to move. Stabilize bare slopes before the next storm rather than after.

Timing is forgiving compared to the mountains. Base, driveway and paver work runs spring through late fall, with mid-winter freezes and wet spells stopping compaction for shorter stretches.

Delivery to Gaithersburg and the Surrounding Area

Order online and size the load with the calculator before you check out. Bulk material arrives by the ton or the cubic yard, and the driver needs a spot that a truck can reach and turn around in. Loose, firm ground beats soft lawn every time.

Have the drop zone cleared before the truck arrives, and know where the pile should sit relative to the work. A pile placed at the far end of a driveway means moving it twice. We deliver across Montgomery County, including Germantown, Silver Spring, Rockville, Bethesda and Potomac.

Questions Gaithersburg Buyers Ask

Can I order material by the ton for delivery in Gaithersburg?

Yes. Bulk gravel, stone, sand and soil are sold by the ton or the cubic yard, and the calculator on each product page converts your area and depth into a quantity. Measure the length, width and compacted depth you need, then round up slightly, since CR-6 and crusher run settle as they compact.

What stone should I use for drainage in Gaithersburg?

Washed stone, not a compacting blend. #57 Stone is the usual pick for French drains and driveway topping, with #8 Crushed Stone for paver joints and tighter bedding and Drain Rock for drywells and downspout runs. Keep the silt out, and make sure the water has somewhere downhill to go.
