Order AB-3 and Crushed Stone in Leavenworth County, KS

Kansas Rock Supply delivers gravel, stone and aggregate delivery in Leavenworth County, KS. AB-3 is the base material most Kansas jobs start from, and it is the term a contractor here uses when ordering base.

Base, drive and paver work runs from the time frost leaves the ground in spring through late fall. Wet spring weeks and frozen winter ground both stop compaction, so timing a delivery around that window matters.

Ground Conditions Across Leavenworth County

Across the Glaciated Region of northeast Kansas, clay subsoil under the drift drains slowly. Water stands on drives and pads after heavy rain and snowmelt.

Loess bluffs shed runoff quickly onto the flat ground below. Bare slopes and roadside banks gully fast after heavy rain, and creek and river banks scour in spring high water.

Valley bottoms carry silty river alluvium, and the clay subsoil under it holds water. A driveway or pad in that ground needs a drainage layer, not just surface stone.

Cold winters bring repeated freezing and thawing. Gravel drives heave through the winter and go soft as the ground thaws from the top down in late winter.

Frost depth is set by each city or county rather than by any statewide table. Check with your local building official before footing or base work.

Materials Delivered in Leavenworth County

Materials arrive by the family that suits the job. Base material, washed stone, sand, soil and decorative rock each answer a different problem on a Leavenworth County site.

AB-3 is the Kansas name for dense-graded crushed limestone base: crushed rock and fines together, graded roughly 1 1/2 inch down. It is also called AB3, aggregate base, or crushed limestone base.

City and county work references the same class.

Use AB-3 for driveways, parking pads, shed and shop bases, and road shoulders. Use 1 Inch Minus for topping a drive or patching soft spots where a full base is more than the job needs.

Keep the two separate; they are close cousins but not the same material.

Clean washed limestone is sold by inch size in Kansas. 1 Inch Clean handles French drains, foundation drains and pipe bedding.

3/8" Crushed Stone covers finer drainage and paver joints, and Screenings bed pavers and flagstone.

Kansas River Rock, also called Kaw River rock, suits decorative beds and dry creek beds. Large River Rock takes on dry creek beds and splash pads under downspouts.

For soil work, Top Soil builds new lawns over heavy clay, and Garden Soil fills raised beds and planting areas. Fill Dirt raises grade before a base course goes down.

Delivery Across Leavenworth County

Order online and choose a quantity by the ton or by the yard. Each product page has a calculator to help size the load before you check out.

A dump truck tips the load in one pile on site. The driver does not place, spot or spread the material, so pick a drop spot that works for the job.

Bulk delivery reaches Leavenworth, Lansing, Basehor, Tonganoxie, Linwood, Easton and Fort Leavenworth. Have the drop area clear and firm before the truck arrives.

Choosing the Right Material

Douglas County sits on Osage Cuestas and the eastern Kansas clay country. Its ground is heavy clay soil weathered from Pennsylvanian shale, between limestone-capped east-facing ridges.

That clay holds water differently from the glacial drift here, so a base that drains well matters more there.

Wyandotte County shares the Glaciated Region ground. Glacial drift over limestone and shale, thick windblown loess on the uplands, and clay subsoil under valley alluvium are the same story on both sides of the line.

Jefferson County also sits in the Glaciated Region. The ground is the same as Leavenworth County's, so the material choices carry across unchanged.

Where clay subsoil holds water, plan a clean stone drainage layer under the base. Where loess slopes shed runoff fast, use rip rap for bank and ditch protection.
