Bulk Gravel Delivery to Capitol Heights, MD

Base, driveway and paver work runs spring through late fall here, and low sites near the shore can stay too wet to compact after summer storms. That window shapes when you order. Maryland Rock Supply delivers gravel and aggregate in Capitol Heights, MD, and CR-6 is the base most local projects start with.

Materials for Capitol Heights Projects

On Capitol Heights paver patios, the layers under the stone decide how long the surface stays flat. The bedding layer levels the pavers, and the base under that carries the load. Both have to drain, or freeze-thaw in a Prince George's winter will lift and rut the surface.

CR-6 is the standard Maryland base. It is a compacting blend of crushed stone down to dust, and it locks up hard under driveways, parking pads, shed bases and paver sub-base. Order CR-6 for the structural layer below any patio.

For the bedding course itself, most crews use Screenings, which local yards call stone dust. Spread an inch or so, screed it flat, and it gives pavers a firm, even bed that still drains.

Coarser stone handles the drainage side. #57 Stone goes into French drains, driveway topping and concrete mixes, and #8 Crushed Stone is the smaller chip for paver joints and tight bedding.

Where a patio meets soil, sand and soil finish the job. Washed Sand beds and levels under pavers and slabs, and Top Soil rebuilds grade around the edges after the work is done.

Ground and Conditions in Capitol Heights

The usual failure here is a thin base. Ground in the Western Shore Coastal Plain is unconsolidated sand, silt, clay and gravel, not weathered bedrock, and it ranges from well drained Top Soil on higher ground to slow-draining clay in low spots.

Put a thin base over wet clay and the first hard freeze-thaw cycle heaves it. The patio ruts, the pavers rock, and you are rebuilding it in a year. Rebuild with a thicker, well-compacted base and a drainage layer that carries water off instead of trapping it.

Prince George's County sets frost depth at 30 inches. That is the number your base has to respect, especially over clay. Summer thunderstorms and nor'easter rain soak the ground fast, and flat land near the Bay and tidal rivers sheds water slowly.

Within 1,000 feet of tidal water, Critical Area rules limit lot coverage, and gravel and stone surfaces count toward it. Plan your footprint before you order.

Delivery to Capitol Heights and the Surrounding Area

Order online and pick your material. The one decision that trips people up is tons versus yards. Stone and gravel are sold by the ton; sand, soil and mulch are usually figured by the cubic yard.

To estimate, measure length by width by depth in feet, divide by 27 for cubic yards, then convert to tons for stone. Round up rather than short. A base that comes up short of its planned depth is a base you redo.

Maryland Rock Supply delivers bulk material across Capitol Heights and Prince George's County, including Bowie, Clinton, College Park, Laurel and Suitland. The truck needs clear access and a spot to dump. Tell us where the pile goes and we will place it there.

Questions Capitol Heights Buyers Ask

What gravel is best for a driveway in Capitol Heights?

CR-6 is the standard choice. It is the Maryland base material, a compacting blend of crushed stone down to dust, and it firms up under traffic. Top it with #57 stone for a cleaner, looser surface, or with Driveway Gravel if you want a finer look. Build the base thick enough to sit above the clay.

How much material will my project need?

Figure volume first: length times width times depth, in feet, divided by 27 for cubic yards. Stone is ordered by the ton, so convert from there. A paver base is usually several inches deep, and bedding is much thinner, so the two layers are measured separately. Use the calculator on each product page and round up.

Size Your Base Before You Order

Start with the calculator on the product page. It turns your patio or driveway dimensions into the tons or yards you actually need, so the base comes out thick enough the first time. Then place your order for CR-6, bedding, sand or topsoil and we will deliver it to your Capitol Heights site.
