Buy Crusher Run in Potomac, MD

Maryland Rock Supply handles gravel and aggregate delivery in Potomac, MD for two kinds of buyers: crews building drives and pads all season, and homeowners fixing one rutted lane. CR-6 is the base most of you order first. Under it sits loam, silt loam and clay loam weathered from schist and gneiss, often flaky with mica, so the base has to carry the load.

Driveway and base materials come first here, along with what the local ground does to them and how bulk drops work in Potomac.

Materials for Potomac Projects

Start with the base, because that is where most Potomac driveway and paver work is won or lost. CR-6, also called CR6 or CR-6 stone, is the standard Maryland base here. It is a compacting blend of crushed stone down to dust, and it locks up hard under a plate or roller. Use it for driveways, parking pads, shed bases and paver sub-base.

Crusher Run, or crush and run, is a separate product from CR-6 on our site. It also binds and compacts, and some crews prefer it for drives and base where they want that blend. Compare the two before you commit to a full load.

On top of a compacted base, Driveway Gravel gives you the wearing surface. For a walkway or garden path that needs a finer, walkable finish, Walkway Gravel is the better pick.

Washed stone, sand and soil

Washed stone handles water and finish work. #57 Stone goes into drainage, French drains, driveway topping and concrete aggregate. Screenings, which most Maryland yards call stone dust, is the bedding for pavers, flagstone and patios.

Sand and soil round out the order. Mason Sand serves brick and block work, paver joints and play sand. Top Soil rebuilds grade and preps lawns and beds after the stone is in.

For decorative beds and dry creek beds, River Rock and Large River Rock are the usual choices.

Ground and Conditions in Potomac

Water drives everything here. The rolling slopes shed storm runoff quickly toward the stream valleys, and silty soil turns soft and hard to compact once it is saturated. Build a drive on ground like that without a crown, a ditch or a drain where water collects, and it will rut.

So the practical order is drainage first, then base. That means a crowned surface, a defined place for water to leave, and a drainage layer of washed stone where the grade keeps water moving at the base. Drain Rock covers French drains, drywells, foundation drains and downspout runs.

Winter adds freeze-thaw cycles, milder than in the mountains but regular. They heave and rut drives built on a thin base or on wet, silty soil. Frost depth runs 30 inches in most county codes across this zone, so a base built to the right depth matters more than a heavier topping.

Erosion shows up after summer thunderstorms and tropical storm rain, scouring stream banks and washing bare, sloping ground during grading. RipRap armors shorelines, stream banks, culvert outlets and slopes against that runoff.

Timing is straightforward. Base, driveway and paver work runs spring through late fall. Mid-winter freezes and wet spells stop compaction for shorter stretches than in Western Maryland, so plan pours and loads around them.

Delivery to Potomac and the Surrounding Area

Bulk material arrives by the truckload and is dumped where you point. Order online by the ton, or by the cubic yard for sand, soil and mulch. If you are unsure of the quantity, measure the area and depth first and size the load from that.

Have the drop spot ready before the truck reaches you. A clear, firm, level place to dump keeps the pile where you want it and keeps the truck off soft ground, which matters on sloping lots after rain.

We deliver across Montgomery County, including Germantown, Silver Spring, Gaithersburg, Rockville and Bethesda. Contractors running several jobs can schedule loads to land as each phase is ready for stone.
