Bulk Aggregate Delivery Across Marion County, AR
Arkansas Rock Supply brings gravel, stone and aggregate delivery in Marion County, AR to driveways, pads, drainage runs and garden beds. The material to start with here is SB-2 base, the dense-graded 1 1/2 inch minus crushed stone with the fines left in.
This is Ozark Plateaus ground: cherty, acid clay loam over limestone and dolostone, with rock and rubble sitting close to the surface on side slopes. That shallow rock is why a thin base shows its weak spots fast.
Ground Conditions Across Marion County
A base that is too thin on this ground moves under a truck tire and pumps water up through the stone. The chert gravel in the soil profile holds a little water, and the clay filling the joints in the rock holds more after a long rain.
Water here leaves through the rock rather than across it. Sinkholes, fractured limestone and losing streams take runoff underground fast across the Ozark Plateaus.
That cuts both ways. A drive that sheds water into a sinkhole or a losing stream can drain well, and a low spot over clay can stay soft for days.
Steep hollow slopes and flashy streams scour drive shoulders, culvert outlets and creek banks in heavy spring rain. Rip rap on those banks and at pipe ends is the usual protection.
Base, drive and patio work runs almost all year in this part of the state. Winter cold snaps and a wet spring are the interruptions, and the late-summer dry spell is the easiest time to get real compaction.
Freezes come in runs from December into February, and shallow freeze-thaw lifts loose gravel and heaves unbound surfaces before spring. Ice storms are a bigger nuisance than deep frost.
No statewide frost depth figure is published. The Arkansas residential code has each jurisdiction set the frost line and requires exterior footings at least 12 inches below undisturbed ground, so confirm the local figure before footings go in.
Materials Delivered in Marion County
SB-2 base is the standard Arkansas base material. It is a dense-graded 1 1/2 inch minus crushed stone with the fines left in so it locks up under a roller, and it goes under driveways, parking pads, shed and building pads and pipe bedding.
Class 7 is the 1 1/2 inch dense grading that yards across the state sell as SB-2, and Class 8 is the 1 inch version.
Section 302 covers select material used as a foundation course underneath. Cities and counties write Class 7 into their own street, sidewalk and parking standards, so ask for Class 7 base when you are working to a written spec.
Around those, Marion County buyers also order washed sand for bedding and leveling, mason sand for brick, block and paver joints, and fill dirt to raise low ground before a base course goes on.
Shredded mulch holds moisture through an Arkansas summer and keeps bare soil from washing in a thunderstorm. For a finer dense-graded material that binds and compacts, crusher run is the other option, though SB-2 is the term to reach for first here.

Choosing the Right Material
Ground across the Ozark Plateaus is cherty, acid clay loam over limestone and dolostone, with chert gravel through the profile and rock close to the surface on side slopes. Baxter County and Boone County sit on that same ground, so the base and drainage choices there follow the same reasoning as here.
Searcy County is different. Its ground is stony, acid silt loam and clay over flat-lying sandstone and shale, with rock benches and ledges and loose colluvium on steep slopes.
Ridge soils are thin and only the foot of a slope carries any depth.
On that thinner, sandier ground, a base course needs to spread the load over less soil, and drainage has to move water off a bench rather than into karst openings. Here, where the rock takes water fast, the drainage layer and the bank protection carry more of the work.
