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

Crushed stone has angular faces from a crusher, so the pieces interlock and compact. Natural Pea Gravel, also called pea rock, is round washed stone, so it stays loose and lets water move through it. Use crushed stone for base and drive work, and Natural Pea Gravel for walkways, play areas and exposed aggregate.

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

Either works, and both are ordered online. A ton is a weight and a yard is a volume, and the two are not the same figure, so pick one and stay with it. Each product page has a calculator to help you size the load before you choose a delivery date at checkout.

Which stone is best for drainage in Martin County?

Clean washed stone with the fines taken out is what drains. Drain rock, usually a 1 1/2 inch clear rock, suits French drains, drywells and footing drains. For finer work, 3/4 clear rock and 3/8 inch crushed stone handle tight bedding and pipe runs. Class 5 holds water, so keep it for base work.

Martin County Class 5 and Gravel Delivery, MN

You need gravel, stone and aggregate delivery in Martin County, MN, and you want to know what to order for the job in front of you. Minnesota Rock Supply delivers bulk material by the ton or by the yard.

Most drives, pads and road work here start with Class 5. Class 5 gravel is what a county or city standard is written against under the same class numbers.

The ground it goes on is the tight prairie till that covers this part of the state.

Ground Conditions Across Martin County

Across the Southern and western prairie till, the working season runs from the thaw into late autumn, which is long by Minnesota standards. Spring load limits go up on South and Central zone roads in early March and come off in April.

That timing matters when you pick a delivery date. A loaded truck needs a road that can take it, and a soft, thawing drive is not ready for a heavy pile.

The till is loamy to clayey and carries shale brought down from the Dakotas. It sits under deep black prairie soil, and much of it has a hummocky pothole surface.

Tight ground like this drains slowly, and closed basins hold water until it is drained or evaporates.

Tile carries most of the farmed ground. Where water still stands, build the base for drainage first and finish with a clean stone layer.

Storms drive sheet, rill and gully erosion on bare cropland and freshly graded lots, and banks cut along rivers in this part of the state. Riprap and clean stone hold slopes and outlets where runoff concentrates.

Winters bring repeated freeze and thaw. Heaving is worst on the tight, shale-rich till where water cannot drain away before it freezes.

The Minnesota Residential Code footing table sets 42 inches for its Zone II counties; that figure is a footing depth set by the building official, not a gravel depth.

Materials Delivered in Martin County

Order by the size that suits the job, from the coarsest drainage stone down to the fines that bed a paver.

Class 5 is the standard base course and carries the most weight in base work.

Class 5 and Class 6 are the base classes, Class 1 and Class 2 are the surfacing classes, and Class 3 and Class 4 are subbase. County highway departments and cities write their own standards against the same class numbers.

Class 2 is a 3/4 inch crushed surfacing aggregate with fines, made from crushed quarry rock. Yards sell it as Class 2 granite, buff limestone or red limestone.

Order it to surface a drive or bed pavers.

For clean drainage, order 3/8" Crushed Stone or 3/8" Natural Pea Gravel where a finer washed stone is wanted. Natural Pea Gravel, also called pea rock, suits walkways, play areas and exposed aggregate work.

Add Washed Sand for bedding under slabs and pavers, and Mason Sand for brick, block and sandboxes.

Choosing the Right Material

Jackson County, Blue Earth County and Faribault County all sit on the same Southern and western prairie till that underlies Martin County. The gray, calcareous Des Moines lobe till is the same ground, so the base and drainage reasoning carries across the line.

On ground like this, choose by what the water does. Tight till sheds slowly, so a clean open stone such as drain rock or 3/4 clear rock belongs in a drainage run.

Class 5 belongs under a drive or pad, where its fines bind and compact.

Finish a drive with Class 2 or driveway gravel over the compacted base, and bed pavers in granite fines. Where runoff concentrates on a slope or an outlet, riprap is the coarse stone for the job.
