What is the difference between topsoil and fill dirt?

Topsoil is screened and holds the organic matter and structure that grass and beds need, so it goes on the surface for lawns, grading and bed prep. Fill dirt is bulk material for raising low ground and building a pad up out of the wet before a base course goes on. Use fill below and topsoil on top.

How deep should a gravel driveway base be in Saline County?

No single depth fits every site here, because the answer depends on your subgrade and how much water reaches it. Tight fall-line clay and concentrated mountain runoff both soften a drive that lacks base. Size the quantity on the product page calculator, then order by the ton or the yard.

Saline County SB-2 Base and Gravel Delivery, AR

Arkansas Rock Supply delivers gravel, stone and aggregate delivery in Saline County, AR, from Benton and Bryant out to Paron. SB-2 base leads the list because it is the base material this part of Central Arkansas builds on.

So do washed stone, sand, topsoil and decorative rock.

Saline County spans two ground regions. Benton, Bryant, Alexander and Bauxite sit on the Central Arkansas fall line, where gravelly clay loam and syenite outcrops meet sandy coastal-plain ground.

Paron sits up in the Ouachita Mountains on stony loam over sandstone, shale and chert.

Materials Delivered in Saline County

SB-2 base is a dense-graded 1 1/2 inch minus crushed stone with the fines left in, so it locks up under a roller.

Class 8 is the 1 inch version.

Cities and counties write Class 7 into their own street, sidewalk and parking standards, so ask for it by that name when you are working to a written spec. Order SB-2 Base for driveways, parking pads, shed and building pads, and pipe bedding.

Washed stone handles everything that has to drain. #57 Limestone is the workhorse size for French drains, foundation and pipe drainage, and concrete aggregate.

3/4" Crushed Stone suits drainage beds, construction entrances and drive surfacing where no fines are wanted.

For finer work, Screenings bed pavers, flagstone and brick, fill joints, and give a tight walking surface. Drain Rock covers dry wells, foundation drains and downspout runs.

RipRap armors banks, slopes and culvert outlets.

Sand and soil round out the load. Washed Sand beds and levels under slabs and pools, while Mason Sand goes into brick, block and stone work and paver joints.

Top Soil is screened for lawns, grading and bed prep.

Decorative stone finishes beds and borders. Arkansas River Rock and Large River Rock build dry creek beds and heavier decorative work.

3/8" Natural Pea Gravel covers walkways, play areas and dog runs.

Choosing the Right Material

Grant County sits in the Timberlands on West Gulf Coastal Plain ground, deep acid sandy loam and sandy clay over unconsolidated sand, gravel, clay, chalk and marl. That is a different profile from Saline County's rocky clay loam and syenite outcrops, so base and drainage choices do not carry straight across.

Garland County and Hot Spring County both reach into the Ouachita Mountains, where stony, gravelly loam sits over folded sandstone, shale, chert and novaculite. On that ground the same dense-graded base and washed drainage stone apply, so the material logic matches Saline County's mountain side.

Ground Conditions Across Saline County

Start with where water goes. On the fall line, tight clay subsoils and flat terraces hold water, and runoff coming off the foothills concentrates where the slope flattens out.

Built-up ground around Benton and Bryant sheds a lot of water onto small lots.

That standing water is the reason a compacted base matters more here than frost does. Wet clay subgrade softens badly under traffic through the winter, and the Arkansas residential code has each jurisdiction set the frost line and require exterior footings at least 12 inches below undisturbed ground.

Up in the Ouachita Mountains around Paron, tilted shale and chert beds shed water off the ridges quickly and funnel it into narrow valleys. Drives and pads there take concentrated flow arriving from above rather than the rain that lands on them.

Erosion follows the same pattern. Flashy runoff scours channels and bare clay slopes on newly cut lots, and steep drive cuts lose surfacing after a big storm.

Riprap and washed stone at outlets and slope toes protect the ground that takes that flow.

Work runs all year in Saline County. Winter rain on clay and midsummer heat set the limits rather than frozen ground, and once the rocky mountain ground drains it compacts well and holds.
