Bulk Aggregates for Patios in Westminster, MD

Planning a patio, driveway or drainage run around Westminster? Maryland Rock Supply handles gravel and aggregate delivery in Westminster, MD, by the ton. For a patio, the job starts under the pavers, and that means CR-6. It is the base material Maryland crews ask for by name, and it compacts into a hard, flat pad.

Westminster sits in the Central Maryland Piedmont, where loam, silt loam and clay loam ground moves once water gets into it. Get the base right first and the surface stays put.

Materials for Westminster Projects

Under pavers and flatwork, the bedding layer is what you feel underfoot. CR-6, also called CR-6 stone, is the standard Maryland base: crushed stone blended down to dust so it binds and compacts. Order it as CR-6. Crusher Run is a separate product that does the same compacting job on drives and shed pads, not the same pile as CR-6. Order it as Crusher Run.

Above the compacted base comes the bedding. Maryland yards call it stone dust, and it is also sold as Screenings. It screeds flat to about an inch and locks pavers and flagstone without shifting. For a patio that sees runoff, a washed layer under the bedding helps water move: #57 Stone is the usual choice for drainage and French drains. Set joints and tight bedding call for #8 Crushed Stone.

Sand still has a place in patio work. Washed Sand beds and levels under pavers and slabs, and masonry and block work take Mason Sand. Where you are rebuilding grade around a new patio, Top Soil brings the lawn back.

Ground and Conditions in Westminster

The failure you see here is almost always the same one: a thin base. A patio or drive built on a thin layer of stone over silty soil ruts and heaves within a season or two. Our freeze-thaw cycles are milder than in the mountains, but the ground still moves. Frost depth runs about 30 inches in most county codes across this zone.

A thicker surface will not help; the pad needs more depth underneath and a way to drain. Excavate deep enough, compact CR-6 in lifts, and give the pad a crown, ditch or drain so water never sits on it. Rolling slopes shed storm runoff fast toward stream valleys, and saturated silt will not compact.

Timing matters too. 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 a January pour day can still work if the ground is dry.

Delivery to Westminster and the Surrounding Area

Order online and pick your material, then choose how to measure it. Loose aggregate is sold by the ton or by the cubic yard, and the two are not the same number. A yard of CR-6 weighs more than a yard of topsoil, so a quote in yards and a quote in tons will not match.

Estimate by volume first: length times width times depth, all in feet, divided by 27 for cubic yards. For a patio base that means the full excavated depth, not just the stone you see. Bulk delivery to a site in Westminster drops the load where the truck can reach, so tell us where the pile should land.

We deliver across Carroll County, including Taneytown, Hampstead, Manchester, Sykesville and New Windsor. If you are not sure which measure to order in, the calculator on the site converts your dimensions to yards and tons.

Questions Westminster Buyers Ask

What gravel is best for a driveway in Westminster?

CR-6 is the standard base for a Westminster drive, compacted in lifts over a crowned, drained subgrade. For the wearing surface, order Driveway Gravel over that compacted base. Where the drive stays wet, put a drainage layer of #57 Stone underneath. Skip the thin base and the drive will rut with every freeze and thaw.

How much material will my project need?

Measure length and width in feet, multiply by the depth in feet, then divide by 27 to get cubic yards. Convert to tons using the material weight, since CR-6 is heavier per yard than topsoil. Use the site calculator to check both numbers before you order.

Check Your Numbers, Then Order

Run your patio or drive dimensions through the calculator first, so you know the yards and tons you need. Then order CR-6, Screenings and the rest of your materials online for delivery in Westminster. Maryland Rock Supply will drop the load where the work is.
