Order SB-2 Base and Crushed Stone in Boone County, AR

Arkansas Rock Supply sells gravel, stone and aggregate delivery in Boone County, AR, and SB-2 base is the material the county's ground calls for. The soil here is cherty, acid clay loam over limestone and dolostone, with chert gravel right through the profile.

That mix holds water in the joints and leaves rubble close to the surface on side slopes. A pad or drive built shallow on ground like that moves, so the base course is where the work starts.

Materials Delivered in Boone County

Start with the project, not the material. A driveway, a patio and a drain each want a different stone, and the local names below are the ones to order by.

SB-2 base, also written SB2 or base stone, 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.

Driveways, shed pads and pipe bedding all start from it.

Table 303-1 sets the aggregate base course gradings as Class 1 through Class 8, and Class 7 is the 1 1/2 inch dense grading sold across the state as SB-2.

Class 8 is the 1 inch version of the same grading. Section 302 covers select material used as a foundation course underneath, and cities and counties write Class 7 into their own street, sidewalk and parking standards.

When you are working to a written spec, ask for Class 7 base. It is the same material under the name engineers and city standards use.

Crusher run is the finer dense-graded option that binds and compacts.

For drainage, drain rock suits French drains, dry wells and downspout runs. RipRap armors banks, culvert outlets and ditch checks where a large angular stone is needed.

Mason sand, garden soil, fill dirt and shredded mulch round out the load for building and planting work.

Ground Conditions Across Boone County

Across the Ozark Plateaus, water leaves through the rock rather than across it. Sinkholes, fractured limestone and losing streams take runoff underground fast.

The residual clay filling the joints still holds water at the surface after a long rain. That is the Arkansas reason a proper base depth matters more than frost.

On steep hollow slopes and flashy streams, heavy spring rain scours drive shoulders, culvert outlets and creek banks. RipRap and clean stone at those points slow the loss.

Base, drive and patio work runs almost all year here. Winter cold snaps and a wet spring are the interruptions, and the late summer dry spell is the easiest time to get real compaction.

This is the coldest corner of Arkansas. 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 is published. The Arkansas residential code has each jurisdiction set the frost line and requires exterior footings at least 12 inches below undisturbed ground.

Choosing the Right Material

Carroll County shares Boone County's ground region, the Ozark Plateaus. The soil there is the same cherty, acid clay loam over limestone and dolostone, with chert through the profile and karst underneath.

Searcy County and Newton County sit on Boston Mountains ground. That is stony, acid silt loam and clay over flat-lying sandstone and shale, with rock benches and loose colluvium on steep slopes.

Ridge soils there are thin, and only the foot of a slope carries any depth. On ground like that, a base course has less to sit on, so drainage and slope protection carry more of the job.
