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

Crushed stone has angular, broken faces from crushing, so it locks together and holds under a base course. Natural Pea Gravel is small rounded stone, sold here as 3/8 inch natural pea gravel, and it shifts under load. Use Natural Pea Gravel for play areas, walkways and bedding, and crushed stone for base, drainage and drives.

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

Both work, and the choice mostly comes down to how you want to compare loads. Base rock, gravel and sand are usually ordered by the ton, while soil, fill and mulch are often ordered by the yard. Size the load with the calculator so the quantity matches the job.

Which stone is best for drainage in St. Charles County?

Washed stone with no fines is the right call, because fines block water. Use 1 inch clean, sold as #57 limestone, for French drains and septic fields. For tighter bedding and smaller pipe work, step down to #67 stone or 3/8 inch clean. Rip rap handles bank and outlet protection.

St. Charles County Base Rock and Gravel Delivery, MO

Missouri Rock Supply handles gravel, stone and aggregate delivery in St. Charles County, MO. Base rock is the material most jobs here start with. It goes under driveways, parking pads, shed bases and farm lanes across the county. Ridgetop ground is silty loess over cherty clay, so a compacted base course matters on almost every build.

Materials Delivered in St. Charles County

We stock the Missouri grades by size, from coarse to fine. Base rock carries the most weight in this county, so start there.

Clean rock means washed stone with no fines, so keep it off base courses. Use it for drainage and concrete work. For finer washed sizes, look at #67 Stone and #8 Crushed Stone.

Ground Conditions Across St. Charles County

The working season shapes when material goes down. Midwinter freezes and heavy spring rain are the usual hold-ups, and low ground near the rivers can stay wet or under water well after a flood crest.

Under that, the ground is silty loess on the ridgetops over cherty clay and limestone, dolomite, sandstone or shale bedrock. That bedrock shows in bluffs and hillsides, and deep silt, sand and clay fill the river bottoms. Sinkholes form where limestone or dolomite lies close to the surface.

Storm runoff drops fast off steep bluffs and hillsides into narrow valleys, and some water drains underground through sinkholes. Loess washes away easily, so runoff gullies bare slopes and road cuts. Rip rap along a bank or outlet holds that ground in place.

Winter here brings frequent freeze-thaw cycles, with January nights below freezing and most days thawing. Frost depth is moderate and set by the local building code. Schedule a delivery for a dry stretch when you can.

You order online and pick a delivery date at checkout. Coverage runs across the county, including O'Fallon, St. Charles, St. Peters, Wentzville, Lake St. Louis, West Alton, Foristell, Portage Des Sioux, Augusta and Defiance.

Choose your quantity by the ton or by the yard. If you are unsure how much a job needs, size the load with the calculator before you check out. A dump truck then delivers the material to your site.

Plan around the season. Spring rain and midwinter freezes slow work, and river-bottom ground can stay soft long after a crest. Setting a date that fits the weather keeps the load usable when it lands.

Choosing the Right Material

Ground next door tells you a lot. St. Louis County sits in the same river hills zone, with the same silty loess over cherty clay and limestone, dolomite, sandstone or shale. Sinkholes form there too, so base and drainage choices look much like St. Charles County. Compare typical projects instead: both counties need compacted base rock under drives and clean stone for drainage.

Lincoln County and Warren County each span more than one zone, covering river hills and the Northern Missouri glacial plains. That means ground can shift from loess and bedrock to glacial material within the same county. Base depth and drainage plans may need to change with it.

Where the ground is similar, the material list stays close: base rock for the base course, crusher run where you want fines to bind, and 1 inch clean for drainage. Where ground is heavier or wetter, lean on washed stone and rip rap for water control.
