Materials Delivered in Washington County
SB-2 base, also called SB2 or base stone, is the standard Arkansas base. It is a dense-graded 1 1/2 inch minus crushed stone with the fines left in.
Arkansas cities and engineers write it into street, sidewalk and parking standards as Class 7 base.
Class 7 is the 1 1/2 inch dense grading and Class 8 is the 1 inch version.
Order SB-2 for driveways, parking pads, shed and building pads, and pipe bedding. Use crusher run where a finer dense-graded material is wanted.
Choosing the Right Material
Benton County sits on the same Ozark Plateaus ground as the plateau side of Washington County. Cherty, acid clay loam over limestone and dolostone, with rock close to the surface.
Base and drainage choices there work the same way.
Madison County spans the Boston Mountains and the Ozark Plateaus. So does Washington County.
Where the ground matches, the material reasoning matches too.
Crawford County spans the Arkansas River Valley and the Boston Mountains. The valley ground is a real difference from the plateau, so drainage there can behave differently.
Ground Conditions Across Washington County
On the plateau side, around Fayetteville, Springdale, Farmington and Prairie Grove, water leaves through the rock rather than across it. Sinkholes, fractured limestone and losing streams take runoff underground fast.
Residual clay filling the joints still holds water at the surface after a long rain. That is why a thin base shows itself here: soft spots, pumping and ruts where the subgrade never dried.
In the Boston Mountains, around West Fork and Winslow, shale beds perch water above the rock. Slopes stay wet and slick, and sandstone above sheds rain straight down the hollow.
On steep hollow drives, runoff cuts ruts and carries surfacing to the bottom. Saturated shale slopes slump after long rain.
Slope protection matters as much as the surface.
Steep hollow slopes and flashy Ozark streams scour drive shoulders, culvert outlets and creek banks in heavy spring rain. Rip rap on those edges takes the energy out of the flow.
Base, drive and patio work runs almost all year on the plateau. Winter cold snaps and a wet spring are the interruptions, and the late-summer dry spell is the easiest time to get real compaction.
In the Boston Mountains, winter ice and mud on steep drives set the limits. Grading and compaction go best from late spring through fall, once the slopes have dried out.
No statewide frost depth figure is published. Arkansas residential code has each jurisdiction set the frost line and requires exterior footings at least 12 inches below undisturbed ground.
Winters are coldest here, so confirm the local figure before footings go in.
