3/4 Inch Crushed Rock and Bulk Aggregates for Fort Benton, MT

Montana Rock Supply handles gravel and aggregate delivery in Fort Benton, MT, and around Chouteau County. On the Hi-Line and the northern glaciated plains, ground is often heavy glacial till that takes water slowly.

That ground is why crushed base course does so much of the work here. It gives you a compacted surface a drive or shop pad can sit on, over soil that would otherwise pump and rut.

Materials for Fort Benton Projects

Start with washed stone. Fort Benton sits on ground that holds snowmelt and storm water, so where that water needs somewhere to go, a clean stone with the fines washed out lets it move instead of ponding.

That is the job for Washed Rock, also called drain rock or 3/4 clean.

French drains, curtain drains and downspout runs use it for the same reason. Fines are what clog a drain, and washing them out of the stone is the point of the product.

3/4" Crushed Stone does similar work in drainage beds, pipe bedding and construction entrances.

Below that in size, 3/8" Crushed Stone suits fine drainage, trench bedding and a tight topping over a compacted base. #57 Stone and #67 Stone are the numbered sizes yards here still specify by number, and both work in drainage and concrete aggregate.

Where the surface is the goal rather than the drain, local buyers say crushed base course, or 3/4 minus. 3/4 Crushed Base Course is the standard base for driveways, shop pads and parking areas.

Driveway Gravel, called road mix, carries enough fines and clay binder to pack hard under a roller for a drive or county-style lane.

Under everything, Pit Run is unprocessed pit gravel for deep fill and raising grade below a surface. It is not a finished driving surface.

Delivery to Fort Benton and the Surrounding Area

You order online and pick a delivery date at checkout. Quantities are ordered by the ton or by the yard, and each product page carries a calculator if you want to size the load before you commit.

Bulk delivery covers Fort Benton and the rest of Chouteau County, including Big Sandy, Geraldine, Highwood, Carter and Loma. The truck tips the load on your site in one pile, so it is worth thinking about where you want that pile to sit before the truck arrives.

Ground and Conditions in Fort Benton

The working season here is short. Frost is in the ground from late autumn into spring, and compaction waits for it to come out, so timing a delivery matters as much as the material itself.

Some of the coldest winters in the state sit on this part of Montana. The northern plains land at the deep end of published frost depth figures for the state, and the local building department sets footing depth.

Across the Hi-Line and the northern glaciated plains, three things drive most of the drainage thinking. Snowmelt ponds on subsoil that is still frozen, a semi-arid year breaks open with a few intense summer storms, and wind moves bare ground.

That combination is why washed stone earns its place on a Fort Benton job. Water that cannot get down through heavy till has to go somewhere, and a clean stone drain gives it a path.
