Buy Bulk Gravel, Sand and Soil in Maryland

Maryland Rock Supply sells bulk gravel and aggregate delivery across Maryland. Water drives the order here. Steep western slopes shed runoff fast, limestone valleys drain down into the rock, and the flat Coastal Plain near the Bay drains slowly. CR-6 handles most of it.

Materials Delivered Across Maryland

Pick your material by size. Coarsest first, finest last.

CR-6 carries the most weight in Maryland. It is the designation local yards use for dense-graded driveway and road base. Same family, different paperwork. Order CR-6 for a drive, a parking pad or a paver sub-base. Order Crusher Run for a drive that needs a binding blend, since it is a separate product from CR-6.

Washed stone is sold by number. #57 Stone and #67 Stone handle drainage and concrete work, with #67 running a size smaller. #8 Crushed Stone and #89 Crushed Stone fit paver joints and tight bedding. 3/4" Crushed Stone and 3/8" Crushed Stone cover drainage beds, drive surfacing and topping over a compacted base. For heavier work, #4 Crushed Stone and Railroad Ballast take trench bottoms, hard standing and severe drainage. Drain Rock serves French drains, drywells, foundation drains and downspout runs.

For shorelines and slopes, RipRap armors Bay and tidal river banks, stream banks, culvert outlets and slopes against wave action and storm runoff. River Rock and Large River Rock build decorative beds, borders and dry creek beds, with the large size for heavier erosion work. 3/8" Natural Pea Gravel, which yards call Natural Pea Gravel or pea stone, suits walkways, play areas, patios and drainage around downspouts.

Sand and soil finish the list. Mason Sand goes into brick and block work, paver joints and play sand. Washed Sand beds and levels under pavers and slabs and mixes into concrete. Washed Sand blends coarse sand and fine gravel for leveling. Top Soil rebuilds grade and preps lawns, Garden Soil fills raised beds, and Fill Dirt raises grade and backfills before base or topsoil goes down. Driveway Gravel resurfaces a drive or tops a compacted base, and Walkway Gravel gives paths a finer, walkable surface.

Ground and Climate Across Maryland

Ground changes fast here, and so does the plan.

In the Western Maryland mountains of Garrett and Allegany, thin stony silt loams sit over shale, siltstone and sandstone, with bedrock close to the surface on the plateau and ridges and deeper soil only in the narrow stream valleys. Frost runs 36 inches in both county codes.

The Hagerstown and Frederick valleys hold silt loam and clay weathered from limestone and dolomite, with rock ledges near the surface between stony ridges such as South Mountain and Catoctin Mountain. Frost is set by each county's building code, so confirm the local figure.

The Central Maryland Piedmont runs loam, silt loam and clay loam weathered from schist, gneiss and other hard crystalline rock, often flaky with mica and carrying rock fragments across rolling hills and stream valleys. Frost is 30 inches in most county codes here.

The Western Shore Coastal Plain, covering Anne Arundel, Prince George's, Southern Maryland and the upper Bay shore, is unconsolidated sand, silt, clay and gravel rather than weathered bedrock, well drained on higher ground and slow draining in low spots. Frost is set by each county: 30 inches in Anne Arundel and Prince George's, 24 inches in Charles. Flat, low ground near the Bay drains slowly, and Critical Area lot coverage rules apply within 1,000 feet of tidal water.

The Eastern Shore, the Delmarva Coastal Plain, is Top Soil, silt and clay with few rocks, well drained on higher ground and wet and poorly drained on flat, low land, with tidal marsh along many shorelines. Frost is 24 inches in Caroline, Dorchester and Queen Anne's, and 32 inches in Cecil.

Baltimore City sits on the fall line and the harbor, with mixed ground: soil over hard crystalline rock in the higher northern and western parts of the city, and Coastal Plain sand, silt and clay in the low areas near the harbor. Frost is set by the city building code, and neighboring Baltimore County uses 30 inches.

How to Order and Size a Load

Order online. Pick the material, choose by the ton or by the cubic yard, and set the delivery address.

To estimate, measure the length and width of the area in feet, then the depth in inches. Convert the depth to feet, multiply all three, and divide by 27 for cubic yards.

Two more things help. First, tell us what the material sits on: existing gravel, bare clay, or fresh fill.
