3/4 Inch Crushed Rock and Bulk Aggregates for Amidon, ND

North Dakota Rock Supply handles gravel and aggregate delivery in Amidon, ND, and the ground here shapes what you order. Across the Little Missouri Badlands, soft sandstone and bentonitic clay sit under thin cover, and that clay swells when wet and cracks as it dries.

Class 5 is the base gravel this market builds on, and it belongs under a drive or pad before anything finer goes on top.

Materials for Amidon Projects

Water is the first thing to plan for on a lot in this country. Short, steep slopes shed rain almost at once, so roof runoff, sump discharge and downspout runs all need somewhere to go.

Washed stone is the material for that work.

Washed Rock, also called clean rock or drain rock, is washed free of fines so water moves through it instead of pooling. It beds drain tile, sump discharge lines, downspout runs and foundation drains.

3/4" Crushed Stone is the coarser drainage and pad stone. It suits French drains, drywells, bin and tank pads, pole barn floors and construction entrances.

3/8" Crushed Stone is the finer drainage and topping size. It beds pipe, drains tight spots and tops a compacted base.

Class 5 is the standard North Dakota base gravel. It goes under driveways, parking pads and shop and shed bases.

Class 13 is the surfacing gravel. It binds and blades well, so it suits an approach, lane or gravel drive that wants a surface rather than a full base course.

For a packed walking surface, Stone Screenings bed pavers and flagstone and fill joints. For red surfacing on paths, yards and lanes, Scoria is the burned lignite clinker North Dakotans mean by that word.

Delivery to Amidon and the Surrounding Area

North Dakota Rock Supply delivers bulk aggregate across Amidon and the rest of Slope County, including Marmarth. You order online, choose a quantity by the ton or by the yard, and pick your delivery date at checkout.

Each product page has a calculator if you want to size a load before you order. A dump truck then tips the load on your site.

A few things help the drop go smoothly. Pick a spot the truck can reach and back out of, and keep the pile clear of overhead lines and soft ground.

Wet clay tracks and approaches turn impassable within an hour of rain, so a dry stretch matters more than the calendar.

Ground and Conditions in Amidon

Work in this part of the state follows the weather more than the calendar. The season closes early, and a delivery date that looks fine in the morning can be a poor bet by afternoon.

Underneath, the Little Missouri Badlands ground is deeply eroded soft sandstone, siltstone and bentonitic clay, cut into buttes and short ridges. Bands of hard red clinker, called scoria here, run through it where lignite seams burned and baked the rock above.

That clay is the practical problem. It swells and turns slick when wet, then shrinks and cracks as it dries, so anything built on it moves.

Rapid gully and rill cutting on bare slopes and slumping on the clay both follow from that.

Long, severe winters and a hard spring thaw heave and soften gravel drives, approaches and township roads. Frost depth is set by the city or county rather than by a statewide table, so check with the local building official before you plan footings.

A compacted Class 5 base is what carries a drive or pad through that cycle. Where water collects, a washed stone drainage layer under the surface keeps the base from sitting wet.
