Large River Rock and Bulk Aggregates for Dearborn, MO

Missouri Rock Supply handles gravel and aggregate delivery in Dearborn, MO for driveways, drainage and banks that keep washing out. Base rock is the local standard here, and it goes under drives, parking pads, shed bases and farm lanes across Platte County.

This part of northern Missouri sits on silty loess over glacial clay till, so runoff cuts rills and gullies fast on bare or freshly graded ground. That shapes what we stock and how we help you pick it.

Materials for Dearborn Projects

Erosion control starts with coarse stone. On Dearborn slopes, swales and creek banks, the job is armoring ground against storm runoff, and that takes rock sized to stay put instead of washing downstream. We organize materials by size, coarsest to finest, so you can match the stone to the job.

At the heavy end, RipRap is the stone for creek banks, pond dams, culvert outlets and slopes taking high water. It interlocks and holds when flow is strong. #4 Crushed Stone, sold as 2 inch clean, covers construction entrances, trench bottoms and heavy drainage where the ground is soft.

For drainage that has to move water instead of blocking it, use washed stone. #57 Limestone, called 1 inch clean, is the Missouri standard for French drains, septic fields and drainage behind walls, with no fines to clog the voids. Drain Rock does the same work on foundation drains and downspout runs. Smaller washed sizes like #67 Stone and #8 Crushed Stone handle tighter spots and paver joints.

Where you need a surface that compacts and binds, base rock and Crusher Run are the choices. Crusher Run carries fines that lock together under a roller, which suits a drive or a lane where you want a firm crust. Driveway Gravel tops a compacted course once the base is set.

Ground and Conditions in Dearborn

The working season drives the schedule here. Upland clay stays wet and soft from late fall into spring, so base and driveway work goes best from late spring into fall, between the wet season and the first hard freeze. Schedule around that window rather than fight it.

Water is the other factor. It perches on the clay subsoil and stands on flat ground from late fall into spring, and heavy spring rain floods creek and river bottoms. A drive or pad built over saturated clay will pump and rut no matter how good the stone is.

So plan the drainage layer and the compaction before you order. Put clean, washed stone where water needs to move, and compact base rock in lifts where you need a firm surface. On loess and till slopes, bare ground rills quickly, so seed or armor anything you strip as soon as the work is done.

Winters here freeze and thaw repeatedly, with January nights averaging well below freezing while many days thaw. The deepest frost in Missouri applies to footing depth, which the local building code sets, not to your gravel base.
