What is the difference between topsoil and fill dirt?

Fill dirt is bulk material for raising low ground and building a pad up out of the wet before a base course goes on. Topsoil is the screened surface layer for lawns, grading and bed prep. Fill goes underneath and topsoil goes on top, and they are not interchangeable on a finished grade.

What is SB-2 base and what is it used for in Monroe 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. It goes under driveways, parking pads, shed and building pads, and pipe bedding. Arkansas cities and counties write it into street and parking standards as Class 7 base.

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

No single depth fits every drive here. The Delta water table is high and the clay barely takes water, so the useful question is how the base drains rather than how thick it is. Each product page has a calculator for sizing the load by the ton or the yard.

Monroe County SB-2 Base and Gravel Delivery, AR

Arkansas Rock Supply sells gravel, stone and aggregate delivery in Monroe County, AR, to contractors and homeowners alike. Some buyers arrive with a set of plans and a spec sheet, and some are topping a drive at the house.

Both start in the same place: SB-2 base, the dense-graded 1 1/2 inch minus crushed stone with the fines left in. This is Delta ground, deep alluvial silt loam and heavy clay, and what you put on top of it decides how the job holds up.

Ground Conditions Across Monroe County

Across the Mississippi Alluvial Plain, the ground is flat and the water table sits high. Clay here barely takes water, so rain stands where it falls and field ditches and bayous drain slowly.

Backwater can hold water for days. That is the condition a base course has to survive, and it is why a pad or drive needs a drainage layer under it rather than a thicker blanket of the same wet material.

The soil is deep alluvial silt loam, silty clay and heavy clay, the buckshot and gumbo ground the Delta is known for. Sandier natural levee ridges and older terraces such as the Grand Prairie sit above it.

Erosion follows the same pattern: sheet erosion off bare cropland silt, ditch and bayou bank sloughing, and river bank caving. Rip rap armors those banks where a rounded stone will not stay put.

Work runs all year here. Wet winter and spring ground is the real constraint, and the midsummer dry spell that shrinks and cracks the clay is the best window for base work.

Winters are short and mild, and frost is shallow. Saturated clay is the winter problem, not frost: a loaded truck will rut a drive deeply with no frost involved at all.

Materials Delivered in Monroe County

Materials group into base, washed stone, sand, soil and decorative stone. Each one below is named the way it is named at an Arkansas yard.

SB-2 base is the standard Arkansas base material, and it is also what cities and counties write into their 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. Section 302 covers select material used as a foundation course underneath.

When you are working to a written spec, ask for Class 7 and you are asking for SB-2.

Class 8 base is the same material in a tighter size, and crusher run is the finer dense-graded option that binds and compacts. Arkansas usually reaches for SB-2 first, so treat crusher run as the alternative rather than the default.

Delivery Across Monroe County

Bulk material arrives by dump truck and the load is tipped on site in one pile. The driver does not place or spread it, so the drop point is worth a thought before the truck arrives.

Clear the spot you want the pile, keep it reachable from the road, and make sure nothing overhead or alongside blocks the truck. Once it is down, moving it is your job.

Choosing the Right Material

St. Francis County and Phillips County each span more than one ground region, taking in both the Mississippi Alluvial Plain and Crowley's Ridge.

Arkansas County sits entirely on the alluvial plain, the same ground as Monroe County.

Where a neighbor's ground includes Crowley's Ridge, the material underfoot changes. Crowley's Ridge ground is higher and better drained than Delta clay, so a base course there sheds water that would stand on flat alluvial ground.

On the alluvial plain the choice turns on drainage rather than slope. A washed stone such as #57 Limestone or Drain Rock moves water through a trench, while SB-2 Base gives you a surface that compacts and carries a load.

Arkansas County shares Monroe County's ground region, so the base and drainage reasoning there is the same as here. There is no difference in the ground itself to work around.
