Gravel, Stone and Soil for Harper County, KS
Kansas Rock Supply handles gravel, stone and aggregate delivery in Harper County, KS. Start with AB-3, the Kansas name for dense-graded crushed limestone base.
AB-3 is crushed rock and fines together, graded roughly 1 1/2 inch down. It locks up tight when it is moisture-conditioned and rolled, which is why it goes under drives, parking pads and shop floors.
Delivery across Harper County
Order online and pick your quantity by the ton or by the yard. Each product page has a calculator if you want to size the load before you check out.
Choose a delivery date at checkout and a dump truck tips the load on site in one pile. That covers Anthony, Harper, Attica, Bluff City, Danville, Waldron and Freeport.
Bulk material arrives as a tipped pile, so have the spot clear before the truck gets there. Once it is down, you move it from there.
Materials delivered in Harper County
Aggregate base is called AB-3, and the requirements for aggregates for base construction sit in Section 1104, inside Division 1100 of the Kansas Standard Specifications for State Road and Bridge Construction.
City and county work references the same class.
For a driveway, AB-3 is the base and driveway gravel surfaces or tops it. For a patio, pair screenings with a clean stone underneath.
For a drain, use a clean washed stone such as 1 inch clean or drain rock. Fines-bearing material will not do that job.
Ground conditions across Harper County
Harper County sits in the Arkansas River Lowlands and the south-central sand prairie. Across that ground, sand, gravel and silt were laid down by the Arkansas River, with stabilized dune sand and a sandy loam over the top.
Sand drains fast, which sounds like good news until a surface course with no binding fines sinks straight into it. The water table also sits close under parts of the valley floor.
Wind moves loose sand as soon as the cover is broken. Spring high water scours banks along the rivers of this part of the state, which is where rip rap and large river rock come in.
The working season here is long. Wet spring weeks and high summer heat are the limits, and sandy ground is back in shape quickly after rain.
Winters are moderate by Kansas standards, but freeze and thaw cycles still move a drive that has no proper base under it. Frost depth is set city by city in Kansas, not statewide.
Choosing the right material
Barber County sits on the Red Hills and Gypsum Hills, where red, iron-stained silty and clayey soil lies over Permian red shale, siltstone and sandstone capped by gypsum beds. That ground is finer and holds water differently from the sandy ground here.
Sumner County and Kingman County share Harper County's ground region, the Arkansas River Lowlands and the south-central sand prairie. The ground there is the same sand, gravel and silt, so the material choices carry over.
On sandy ground, a fines-bearing base such as AB-3 gives you a surface that binds. Clean stone such as 1 inch clean or #4 Crushed Stone gives you drainage instead.
For beds and planting, Garden Soil and Shredded Mulch hold moisture through a hot, windy summer. Fill Dirt raises grade before a base course goes down.
