What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular, fractured faces from crushing, so it locks together and stays put. Base rock, #57 limestone and 3/4 inch clean are all crushed products. Natural Pea Gravel is small, rounded and smooth, so it shifts underfoot and drains freely. Use crushed stone for base and structural work, and Natural Pea Gravel for play areas, walkways and bedding.

Should I order material by the ton or by the yard?

Either works. Tons measure weight, yards measure volume. Most buyers pick whichever unit they already think in, then use the calculator to size the load for the area they are covering. Let the calculator do the converting and order the quantity it gives you.

Which stone is best for drainage in Oregon County?

Washed stone with no fines moves water best. That means 1 inch clean (#57 limestone), 3/4 inch clean or drain rock, depending on the job. Base rock and crusher run hold fines and compact instead; they belong under a drive, not in a French drain.

Oregon County, MO Aggregate and Rock Delivery

Heavy storms send fast runoff off rocky slopes into narrow valleys and creeks here. On the flatter uplands, much of that water drains underground through sinkholes and cracks in the bedrock. Missouri Rock Supply delivers gravel, stone and aggregate delivery in Oregon County, MO, and base rock is the material that handles most of it. It locks up under a drive, sheds water off a pad, and stands up to chert and clay ground.

Materials delivered in Oregon County

Missouri Rock Supply stocks the full range of Missouri quarry products. Here is how they run, coarsest to finest, and what each size is good for on Oregon County ground.

Base Rock is the standard Missouri base material. Type 1 and Type 5 are 1 inch dense-graded mixes of crushed stone and fines, with Type 5 also capping the finest dust fraction. Type 7 is a coarser 1-1/2 inch grade. Order it for driveways, parking pads, shed bases and farm lanes.

Clean rock means washed stone with no fines, most often 1 inch clean. It never means base rock or crusher run, which need those fines to bind. Ask for clean rock for drainage, base rock for a foundation.

Ground conditions across Oregon County

Spring is the wettest stretch here, and storms can raise creeks quickly. Chert and rock in the ground slow digging more often than mud does. Time a delivery around that pattern, and you spend less time fighting a wet hole.

The ground itself is cherty, rocky clay over limestone and dolomite. It runs thin and stony on slopes and ridges, with a thin silty cap on some flatter uplands. Sinkholes, springs, caves and losing streams are common.

That karst ground changes how you build. Storm runoff washes soil and chert gravel off slopes and graded ground into creeks, and soil can wash down into sinkholes and openings in the bedrock. Slope protection matters. So does a drainage layer that moves water away instead of letting it sit.

January nights still average below freezing and days usually thaw, so freeze-thaw cycles are frequent. Frost depth is shallower than northern Missouri, and the local building code sets footing depth.

Choosing the right material

Howell County and Shannon County sit in the same rocky Ozark ground, so the base and drainage choices there look like Oregon County's. Expect the same cherty clay over limestone and dolomite, the same sinkholes and losing streams. The projects differ more than the ground does.

Ripley County spans more than one ground zone, reaching into the Bootheel and Southeast Lowlands. Ground shifts as you move toward that side, so base and drainage choices shift with it.

On Oregon County slopes, build a base that drains and armor what water runs across. On flatter uplands, watch where water disappears into the bedrock and keep it out of the subgrade.
