Bulk Gravel and Stone Delivery in Clay County, MO
Missouri Rock Supply handles gravel, stone and aggregate delivery in Clay County, MO. Our busiest window runs from late spring into fall, between the wet season and the first hard freeze. Upland clay stays wet and soft from late fall into spring, so that is when base rock and driveway work goes best.
Base rock is the material most Clay County orders start with. It is the standard Missouri base.
Materials Delivered in Clay County
We stock four material families: base, washed stone, sand, and soil and decorative. Each one has a job it does well on this ground.
Base materials
Base rock, also called type 5 base or type 1 base, is a 1 inch dense-graded mix of crushed stone and fines. Type 5 caps the finest dust fraction, and Type 7 is a coarser 1-1/2 inch grade. Order it for driveways, parking pads, shed bases and farm lanes. It is the standard Missouri base material.
Crusher Run is the choice where you want a compacting, binding material with fines. It locks together under a plate or roller and works well on drives and base courses.
Washed stone
Washed stone has no fines. It drains instead of binding, so keep it away from base courses. #57 Limestone, sold locally as 1 inch clean or 57 stone, is the workhorse for drainage, French drains, septic fields and concrete aggregate. 3/4" Crushed Stone covers drainage beds, drive surfacing and construction entrances. #67 Stone handles drainage and concrete work at a slightly smaller washed size.
Sand
Mason Sand goes into brick and block work, paver joints and play sand. Washed Sand, also called concrete sand, is for leveling, bedding and base under slabs.
Soil, fill and decorative
Top Soil rebuilds lawns and beds over heavy clay and fill. Fill Dirt raises grade and fills low spots before a base rock course goes down. River Rock covers decorative beds, borders and dry creek beds.

Have the drop spot clear and reachable before the truck arrives. A firm, level area near the work keeps the load where you want it. Mark any buried lines or irrigation first.

Ground Conditions Across Clay County
Water is the driver here. Rain and snowmelt perch on the clay subsoil and stand on flat ground from late fall into spring. Heavy spring rain floods creek and river bottoms.
That changes how you build. On flat prairie ground with a tight claypan, plan a drainage layer so water has somewhere to go. Base rock alone will not fix a wet subgrade.
Runoff cuts rills and gullies in loess and till slopes, worst on bare or freshly graded ground. High water scours creek and river banks. Rip rap on those banks and outlets slows the loss.
Frost matters here too. The hardest winters in Missouri bring January nights well below freezing while many days thaw, so the ground freezes and thaws over and over. Frost depth is the deepest in Missouri, and the local building code sets footing depth.
Choosing the Right Material
Start with the ground, then pick the material. On wet, flat ground, drainage comes first and base rock comes second. On a slope, plan for runoff before you surface anything.
Platte County, Ray County and Clinton County all sit in the same Kansas City metro region and the same Northern Missouri glacial plains ground zone as Clay County. Silty loess over glacial clay till, dense subsoils, slow drainage. The ground is similar, so the material choices are similar too.
What shifts is the project mix. Clay County work leans toward driveways, parking pads and farm lanes on upland clay. Neighboring counties lean toward the same base and drainage choices, with more bank and outlet work where creeks and river bottoms flood.
