Ground Conditions Across Clark County

Clark County spans two ground regions. Around Arkadelphia, Gurdon and Okolona the ground is deep, acid sandy loam and sandy clay over unconsolidated sand, gravel, clay, chalk and marl, with heavy dark prairie clay on the chalk and marl belt.

Around Amity and Alpine the ground is stony, gravelly loam over folded sandstone, shale, chert and novaculite, with rock fragments through the profile and shallow soils on the long ridges.

On the coastal plain side, sandy topsoil sits on a dense clay subsoil, so water soaks in, perches and then runs sideways. Flat ground and slow bayous keep the water table high for days after heavy rain.

In the Ouachita Mountains, 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.

Bare sand cuts and gullies quickly under intense Gulf rainfall, and thunderstorm runoff scours drive shoulders and pipe outlets. Fast ridge runoff and steep drive cuts lose surfacing after every big storm.

Work runs all year in both zones. Winter and spring rain on sandy clay is the limit on the coastal plain, and a long wet spell keeps hauling ground soft.

In the mountains, winter ice and a wet spring are the limits, and once the rocky ground drains it compacts well and holds.

No statewide frost 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.

Freezes are short and shallow across south Arkansas, and rock is often close enough to the surface in the mountains that bearing, not frost, sets the footing.

Materials Delivered in Clark County

SB-2 base is the standard Arkansas base material: a dense graded 1 1/2 inch minus crushed stone with the fines left in. Cities and counties write it into their own street, sidewalk and parking standards as Class 7.

Use SB-2 Base for driveways, parking pads, shed and building pads and pipe bedding. Class 8, the 1 inch version, covers the same uses in a tighter size.

Washed sizes handle drainage and concrete work. #57 Limestone is the workhorse washed size, used in French drains, foundation and pipe drainage, concrete aggregate and as a clean top over a compacted base.

3/4" Crushed Stone is a washed stone with no fines, for drainage beds, construction entrances and drive surfacing. Drain Rock covers French drains, dry wells, foundation drains and downspout runs.

Rounded stone comes out of the river gravel deposits. 3/8" Natural Pea Gravel suits walkways, play areas, dog runs and drainage, and Arkansas River Rock works in decorative beds, borders, dry creek beds and splash pads.

For bank and slope work, RipRap armors creek and bayou banks, lake edges, culvert outlets and ditch checks. It is usually broken sandstone, limestone or central Arkansas syenite.

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

Top Soil covers lawns, grading and bed prep, and Fill Dirt raises low ground and builds a pad up out of the wet before a base course goes on.

Choosing the Right Material

Hot Spring County and Pike County both span the Ouachita Mountains and the West Gulf Coastal Plain, the same two ground regions Clark County spans. The ground is the same, and so is the material choice.

Ouachita County sits in the Timberlands on the West Gulf Coastal Plain, with the same deep, acid sandy loam and sandy clay over unconsolidated sand, gravel, clay, chalk and marl. Sandy pine uplands cover most of it, with heavy dark prairie clay on the chalk and marl belt.

That clay belt is the difference worth knowing. Where heavy prairie clay sits under a thin sandy top, water perches instead of draining away, so a compacted base course and a clean drainage layer both matter more than they do on ground that sheds water freely.
