Johnson County, AR Gravel and Landscape Rock Delivery
Arkansas Rock Supply handles gravel, stone and aggregate delivery in Johnson County, AR, and the load starts with SB-2 base. That is the dense graded 1 1/2 inch minus crushed stone with the fines left in, and it is the material Arkansas calls base stone.
Size your load with the calculator on each product page, then order by the ton or by the yard. Johnson County spans two ground regions, so the soil under a drive in the river valley is not the same as the soil on a mountain slope.
Ground Conditions Across Johnson County
In the Arkansas River Valley around Clarksville, Lamar, Coal Hill and Knoxville, the bottoms and terraces carry deep silt loam and clay. The water table sits high near the river, and clay subsoils let go of water slowly.
A wet clay subgrade softens and pumps under traffic all winter, so an under-built base in the valley fails from below rather than from above. Backwater after heavy rain upstream adds to the problem on low ground.
In the Boston Mountains around Hagarville, Oark and Ozone, the ground is stony, acid silt loam and clay over flat-lying sandstone and shale. Ridge soils are thin, and only the foot of a slope carries any depth.
Shale beds perch water above the rock, so slopes stay wet and slick while the sandstone above sheds rain straight down the hollow. A steep gravel drive takes water arriving from uphill, not just the rain that falls on it.
Slope length and gradient drive erosion on the mountain side. Runoff on steep hollow drives cuts ruts and carries surfacing to the bottom, and saturated shale slopes slump after long rain.
On the valley side, bank scour and flood flow along the river and its lakes do the damage, along with sheet erosion off bare valley clay in spring thunderstorms.
Work runs nearly all year in the valley. A wet late winter and spring is the real limit, and summer heat can dry a surface before it can be rolled.
Mild valley winters are broken by short hard freezes and the occasional ice storm. Arkansas sets no statewide frost figure; the residential code has each jurisdiction set the frost line and requires exterior footings at least 12 inches below undisturbed ground.
Materials Delivered in Johnson County
SB-2 base is the standard Arkansas base material. Cities and counties write Class 7 into their own street, sidewalk and parking standards.
Order SB-2 Base for driveways, parking pads, shed and building pads and pipe bedding. Crusher Run is the finer dense-graded option where a material that binds and compacts is wanted, and it is also sold as Class 8, the 1 inch minus version.
Choosing the Right Material
Pope County and Johnson County share part of the same ground. Pope County also spans the Arkansas River Valley and the Boston Mountains, so the base and drainage thinking there runs on the same two sets of conditions.
Madison County and Newton County sit in the Ozark Mountains, and Newton County's ground is Boston Mountains: stony, acid silt loam and clay over flat-lying sandstone and shale, with rock benches and ledges.
That is the same mountain ground Johnson County has around Hagarville, Oark and Ozone, so a base or drainage choice made for one fits the other.
Madison County spans the Boston Mountains and the Ozark Plateaus. Where the ground differs, it is the plateau side that differs, and the plateau soils are not the same as the valley clay in Johnson County.
For a drive on valley clay, SB-2 base gives you a dense graded material that locks up under a roller. For a steep mountain drive, drainage above the surface matters as much as the base itself.
For a patio, screenings bed the pavers and #57 limestone handles drainage behind them. For a French drain or a downspout run, a washed size with no fines carries water instead of trapping it.

Questions About Johnson County Material
Which stone is best for drainage in Johnson County?
A washed size with no fines is what drainage wants. #57 limestone handles French drains, foundation and pipe drainage, and a clean top over a compacted base.
3/4 inch clean limestone works for drainage beds and construction entrances.
What do I need to have ready for a bulk delivery?
Have the drop spot clear, firm and reachable by a dump truck, and know your quantity before you check out. The truck tips the load in one pile, so pick a spot that works for where the material is going.
What is the best base material for a patio in Johnson County?
SB-2 base is the Arkansas base material for a patio, and it is what cities and counties write into their standards as Class 7. It is a dense graded 1 1/2 inch minus crushed stone with the fines left in, so it locks up under a roller.
