AB-3 is the base most Kansas work is built on, and it is the first thing to get right on a drive, a parking pad or a shop floor. From there you top it, drain it or dress it with the right size of rock, sand or soil.
Materials Delivered in Thomas County
AB-3 is dense-graded crushed limestone base: crushed rock and fines graded together, roughly 1 1/2 inch down, that locks up tight when it is moisture-conditioned and rolled. In Kansas, and AB-3 is the term a contractor here uses when ordering base.
City and county work references the same class, so the word travels from the spec book to the truck.
Order AB-3 for driveways, parking pads, shed and shop bases and road shoulders. When a full base is more than the job needs, 1 Inch Minus tops a drive, patches soft spots and builds up shoulders.
Sand and soil round out a load: Washed Sand for bedding and levelling under slabs and pavers, Mason Sand for brick and block work and paver joints, and Fill Dirt to raise grade and build up low spots before a base course goes down.
Ground Conditions Across Thomas County
Across the High Plains of western Kansas, the working season is long. The difficulty is not waiting for the ground to dry out; it is getting moisture into material and holding it there long enough to compact.
The soils are silty loess and sand over the Ogallala Formation of sand, gravel and cemented beds. Cemented Ogallala is called mortar bed locally, and hard caliche layers sit close to the surface in places.
A base placed over that ground has to be built to shed water rather than sit in it.
Rainfall runs about 15 to 25 inches a year here, but it arrives in heavy summer storms on tight silt and caliche that will not take it. Water runs to the low spots and playas, which is where a drive or a pad tends to soften first.
Wind is the main agent of erosion. Bare silt and loose sand blow, drifting across drives and stripping unbound surfaces, and cloudbursts cut steep-sided draws.
That is why unbound surfaces want a bindered material and exposed slopes want rock on them.
Winters are the coldest, windiest and driest in Kansas, with hard freezes and rapid thaws. Kansas sets frost depth city by city rather than statewide, so footing depth is a question for the local building official, not a single number.
Choosing the Right Material
Sherman County, Gove County and Decatur County all sit in the High Plains, and all three share Thomas County's ground region. The same silty loess and sandy soils over the Ogallala Formation run through them, with mortar bed and shallow caliche in places.
The ground is the same, so the base and drainage choices are the same.
That means the decision comes down to the job rather than the county line. A drive that takes traffic wants AB-3 underneath.
A drain or a downspout run wants clean rock that water moves through, such as 1 Inch Clean or Drain Rock. Decorative beds want rounded stone, and slopes that face storm runoff want RipRap.

A pile placed near the work keeps the material where it is needed.
Questions About Rock and Gravel in Thomas County
What is the difference between crushed stone and Natural Pea Gravel?
Crushed stone has angular faces because it is run through a crusher. Natural Pea Gravel is rounded, which is why it feels comfortable underfoot on walkways and play areas.
The shape matters more than the size: angular stone locks together and holds position, while rounded stone stays loose and shifts under traffic. Use crushed stone where you want a surface to stay put.
Should I order material by the ton or by the yard?
Both work, and either one gets you the same pile. Ordering by the ton is common when you are matching a weight, and by the yard when you are matching a volume.
Each product page has a calculator you can use to size the load before you order. Pick whichever unit you are comfortable with and set the quantity at checkout.
Which stone is best for drainage in Thomas County?
Clean washed stone is what moves water, and the size depends on the job. 1 Inch Clean suits French drains, foundation drains and pipe bedding, while 3/4" Crushed Stone works for drainage beds and trench backfill.
RipRap handles ditch lining and culvert outlets. Fines-bearing material like AB-3 does not drain, so keep it for bases rather than drains.
