Gravel, Stone and Soil for Frederick County, MD
Start with the numbers, then pick the material. Measure your drive, pad or bed in feet, work out the square footage, and multiply by the depth you want. That gives you cubic yards, and the tonnage follows from there. Maryland Rock Supply sells gravel, stone and aggregate delivery in Frederick County, MD, and CR-6 is the base most jobs here start with.
From Frederick down to Brunswick and out to Thurmont, the ground under the job decides how deep that base needs to go. Order online, and we run it to the site.
Materials delivered in Frederick County
Most orders fall into three buckets: a driveway, a patio or paver area, and a drain. Here is what we send out for each.
Driveways and pads
CR-6 is the designation Maryland yards use for dense-graded driveway and road base. For a drive, compact CR-6 in lifts rather than dumping one deep layer.
Patios, pavers and walkways
Drains and wet spots
- #57 Stone for French drains, driveway topping and concrete aggregate.
- #67 Stone for drainage and concrete work at a slightly smaller size than #57.
- Drain Rock for French drains, drywells, foundation drains and downspout runs.
- #8 Crushed Stone for fine drainage, paver joints and small-chip surfacing.
- RipRap for stream banks, culvert outlets and slopes against storm runoff.
- Top Soil for lawn and bed prep and rebuilding grade after construction.
Ground conditions across Frederick County
Frederick County spans two ground zones, and they behave differently under a base.
On the valley floors around Frederick, Brunswick, Thurmont and Walkersville, you are on silt loam and clay weathered from limestone and dolomite, with rock ledges close to the surface between South Mountain and Catoctin Mountain. Water drains down through cracks in that rock.
Out in the Central Maryland Piedmont around Mount Airy, Monrovia, New Market and Ijamsville, the soil is loam, silt loam and clay loam weathered from schist and gneiss, often flaky with mica and carrying rock fragments. Rolling slopes shed storm runoff fast toward stream valleys, and that silty ground turns soft and hard to compact when saturated. Crown the drive, or add a ditch where water collects.
Erosion follows the same split. In the valleys, watch concentrated runoff washing soil into rock cracks and sinkholes, plus stream bank scour along creeks and the Potomac after heavy rain.
Timing matters too. Base and driveway work runs spring through late fall in both zones. After heavy spring rain in the valleys, check low spots for new depressions before you lay base on limestone ground.
Delivery across Frederick County
Ordering online is the straightforward part. Pick your material, enter the quantity by the ton or the yard, and give us the delivery address.
A bulk delivery means a truck that needs room to get in, turn around and dump. Clear the driveway, move vehicles, and mark anything low that you do not want driven over. Have a spot picked for the pile so the load lands where you want to shovel from, not in the middle of the access.
We cover Frederick, Brunswick, Thurmont, Walkersville, Middletown, Mount Airy, Monrovia, Emmitsburg, Jefferson, Myersville, Adamstown, Point of Rocks, New Market and Woodsboro. If your job is on a narrow lane or a steep gravel drive, say so when you order so the driver knows what to expect.
Choosing the right material
How much the ground changes your order shows up when you compare Frederick County with the counties next door.
Howard County and Carroll County sit in the Central Maryland Piedmont, the same zone as Frederick County's Mount Airy and Monrovia side. The ground is similar, so the base choice does not shift much: CR-6 compacted in lifts, washed stone for drainage. What changes is typical project mix, with tighter lots and more paver work than open rural drives.
Montgomery County sits in the Capital Region but shares that same Piedmont ground zone of loam, silt loam and clay loam over schist and gneiss. Again the ground is similar, so drainage and base depth follow the same reasoning.
Order CR-6 and the rest of the load
CR-6 is the material most Frederick County jobs start with, and it is the one to sort out first. Measure the area, work out your depth, and order the base before anything else. Add stone dust, washed stone, sand or topsoil to the same order and it all arrives together. Head to the CR-6 page, pick your quantity, and place the order online.
