The ground tells you why. Silty loess sits on the ridgetops over cherty clay and limestone, and that loess washes away fast when storm runoff comes off the bluffs.
Delivery across Cooper County
You order online and choose a quantity by the ton or yard. If you are unsure how much a pad or lane needs, the calculator sizes the load before you commit. Pick a delivery date at checkout and a dump truck brings the material to your site.
We deliver to Boonville, Pilot Grove, Otterville, Bunceton, Prairie Home, Blackwater and Wooldridge, plus the rural lanes in between. A bulk delivery is dumped where the truck can reach, so mark the spot before the driver arrives. Low ground near the rivers can stay wet well after a flood crest, so plan the drop for firmer ground.
Materials delivered in Cooper County
Base rock carries most of the work here. It is also called type 5 base or type 1 base. Type 5 also caps the finest dust fraction, and Type 7 is a coarser 1-1/2 inch grade.
Order base rock for driveways, parking pads, shed bases and farm lanes. For a surface course over compacted base rock, use driveway gravel or road rock. Where you want a material that compacts and binds with its own fines, crusher run is the pick.
Ground conditions across Cooper County
Start with the soil, because an under-built base fails on it. Silty loess on the ridgetops washes away easily, so bare slopes and road cuts gully out in a hard storm. Compact base rock in lifts and crown it so water runs off instead of soaking in.
Cherty clay and limestone, dolomite, sandstone or shale bedrock show in the bluffs and hillsides. Sinkholes form where limestone or dolomite lies close to the surface, so drainage has to go somewhere planned. Storm runoff drops quickly off the steep slopes into narrow valleys, and some water drains underground through those sinkholes.
In the river bottoms, deep silt, sand and clay sit under the fields. The Missouri and Mississippi flood their bottoms in long wet spells, so low ground can stay wet or under water well after a flood crest. Midwinter freezes and heavy spring rain are the usual hold-ups on a job.
Frost depth here is moderate. January nights average below freezing and most days thaw, which gives frequent freeze-thaw cycles through winter. That depth is set by the local building code, not by us.
Choosing the right material
Pettis County sits on clay, silty clay and sandy clay weathered from shale, limestone and sandstone, with dense, slow-draining clay subsoil under much of the flatter ground. Where drainage stalls, a washed stone layer under the base helps more than extra base depth.
Saline County is silty loess over glacial clay till, deepest on the hills and bluffs along the Missouri River, with a tight claypan under the flat prairies. That claypan sheds water slowly, so a drain rock or clean stone layer earns its place.
Morgan County is cherty, rocky clay over limestone and dolomite, thin and stony on slopes and ridges, with sinkholes, springs, caves and losing streams. There the ground drains on its own and the risk runs the other way, so watch for water disappearing under a base.
In Cooper County the mix of loess ridges, cherty hillsides and river bottoms means base rock does most of the work, with washed stone where water has to move.
