Can I order material for a commercial or contractor job?

Yes. Maryland Rock Supply supplies base, washed stone, sand and soil for residential and commercial work across Prince George's County. Contractors ordering for parking pads, drainage runs or site work can size loads by the ton or yard and schedule bulk delivery. Choose the material that suits the job, then set the quantity in tons or yards at checkout.

When is the best time of year to order base material in Prince George's County?

Spring through late fall is the window for base, driveway and paver work, with only short winter stoppages for frozen ground. Summers bring thunderstorms, nor'easters and tropical rain, so low, flat sites near the Bay and tidal rivers can stay too wet to compact. Order when the ground is workable and dry enough to lock up.

What is the difference between topsoil and fill dirt?

Fill dirt raises grade, backfills and fills low spots before anything else goes down. Screened topsoil goes on last, for lawns and beds, because it carries the organic content plants need. Use fill dirt under a base or a new grade, then cap it with topsoil where you plan to grow something.

Prince George's County, MD Aggregate and Rock Delivery

Planning a driveway, a paver patio base, or a drainage run? Maryland Rock Supply handles gravel, stone and aggregate delivery in Prince George's County, MD. Most jobs here start with CR-6, the compacting crushed stone blend Maryland yards use for drives and pads. The ground under it is unconsolidated sand, silt, clay and gravel, not bedrock. That is why a proper base matters more here than in rocky country.

Materials Delivered in Prince George's County

CR-6 is the workhorse. It is a dense-graded blend of crushed stone down to dust that locks up under a plate compactor or roller. Highway work calls for graded aggregate base, or GAB. Order CR-6 for driveways, parking pads, shed bases and paver sub-base.

Washed stone is sold by number, not by blend. That means clean stone with the fines washed out, so water moves through it instead of pooling.

Ground Conditions Across Prince George's County

In Prince George's County, trouble usually starts with a thin base laid over wet clay. It heaves, ruts and pumps within a season. Unconsolidated sand, silt, clay and gravel sit under this county, and low spots drain slowly after a storm. Fix it with depth and drainage, not more surface stone.

Winters are milder than inland, but repeated freeze-thaw still moves a shallow base. Frost depth is set by each county, and Prince George's is 30 inches. Dig the base deep enough and compact it in lifts.

Near the Bay and tidal rivers, waves and storm tides eat at shorelines and bluffs, and runoff cuts gullies across sandy slopes. RipRap armors those banks. Within 1,000 feet of tidal water, Critical Area rules limit lot coverage, and gravel and stone surfaces count toward it. Base, driveway and paver work runs spring through late fall, but low shore sites can stay too wet to compact after storms.

Delivery Across Prince George's County

Order online and size your load by the ton or the cubic yard. Base and washed stone usually price by the ton because weight is what a dump truck carries. Soil, sand and mulch often go by the yard. Know your square footage and depth before you order.

A bulk delivery drops loose material, so plan where the truck can reach and where the pile should sit. We cover Bowie, Clinton, College Park, Laurel, Suitland, Fort Washington, Greenbelt, Hyattsville, Beltsville, Oxon Hill, Glenn Dale, Accokeek, Lanham and Brandywine.

Choosing the Right Material

Next door in Montgomery County, the ground changes. That county sits in the Central Maryland Piedmont, with loam, silt loam and clay loam weathered from schist, gneiss and hard crystalline rock, often flaky with mica. Rock fragments and rolling stream valleys mean a base there meets different resistance than our coastal plain soils.

Charles County sits in the same Western Shore Coastal Plain zone as Prince George's, so the ground is similar: sand, silt, clay and gravel, well drained on high ground and slow in low spots. There the comparison is project mix, not soil. Base and drainage choices carry over almost unchanged.

Match the material to the job. CR-6 for anything that takes traffic. #57 stone and drain rock for water. Screenings and washed sand for bedding. Topsoil and garden soil for planting, fill dirt for grade.

Get Your Quantity Right, Then Order

Measure your area, pick your depth, and run the numbers through the calculator before you order. That keeps a driveway or drainage job from coming up short mid-build. When you know your yards or tons, Maryland Rock Supply is ready to load and deliver CR-6, washed stone, sand or soil to your Prince George's County site.
