St. Louis County, MO Gravel and Landscape Rock Delivery
Start with the calculator for gravel, stone and aggregate delivery in St. Louis County, MO. Enter your area and depth, and it sizes the load before you pick a material. Most jobs here start with base rock, the standard Missouri base, then take a surfacing or drainage grade on top.
Missouri Rock Supply delivers bulk loads across the county, from the loess ridgetops down to the river bottoms. Ground like that punishes an under-built base, so the material choice matters more than the tonnage.
Ground Conditions Across St. Louis County
The county sits in the Missouri and Mississippi river hills. Ridgetops are silty loess over cherty clay and limestone, dolomite, sandstone or shale bedrock that shows in the bluffs and hillsides. The river bottoms hold deep silt, sand and clay.
Loess washes away easily, so storm runoff gullies bare slopes and road cuts. Water also drains underground through sinkholes where limestone or dolomite lies close to the surface. High water scours the banks of the big rivers and their tributaries.
That ground changes what you build. A driveway on loess needs a compacted base rock course that spreads the load instead of pumping into soft silt. Slopes need slope protection and a drainage layer, not just surface rock. Low ground near the rivers can stay wet well after a flood crest.
Winter brings frequent freeze-thaw cycles, with January nights below freezing and most days thawing. Frost depth here is moderate and set by the local building code. Plan the working season around midwinter freezes and heavy spring rain.
Materials Delivered in St. Louis County
Order by project type. Here is what goes down for a driveway, a patio, a drain or a bed.
Base rock carries most of the weight in this county. It is a 1 inch dense-graded mix of crushed stone and fines, and Type 5 also caps 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.
Washed stone is the other half of the list. Keep 1 inch clean, 3/4 inch clean and clean rock for drainage and concrete work, since clean rock has no fines and will not compact into a base. Use screenings for paver and flagstone bedding, and rip rap on creek banks and culvert outlets.
Choosing the Right Material
Start with the base, then work up. For a driveway, base rock compacted in lifts, then driveway gravel or road rock on top. For a patio, screenings or gravel sand for bedding over a compacted base. For a drain, 1 inch clean or drain rock wrapped and piped away from the structure. For a bed, river rock, Natural Pea Gravel or shredded mulch.
Franklin County sits in the same region but spans the Ozark Plateau and the river hills. Rockier Ozark ground there can mean shallower soil over bedrock and more rock excavation before a base goes down.
St. Charles County shares this county's zone. The ground is similar, silty loess over cherty clay and bedrock with sinkholes near the surface. The material choice is much the same, and the projects lean toward new-build drives and pads.
The independent city of St. Louis shares the zone too. Ground is similar, but tighter lots mean more drainage work and more clean stone for downspouts and tight bedding.
