Crushed base course, also called 3/4 minus, is the base material this part of the state builds on.

Ground here is glacial till over shale, heavy and slow to drain. That shapes what you put down and when you put it down.

Materials for Westby Projects

Washed stone is the place to start on any drainage job. Water has to move, and clean stone lets it.

Around a foundation, a downspout run or a drywell, the fines are the problem, not the rock.

Washed Rock, also called drain rock or 3/4 clean, goes into French drains, curtain drains and downspout runs. It is washed so the voids stay open and water keeps moving instead of sitting in mud.

3/4" Crushed Stone works for drainage beds, pipe bedding and construction entrances. 3/8" Crushed Stone is the finer version, for trench bedding and a tight topping over a compacted base.

For a drive or a shop pad, 3/4 Crushed Base Course is the standard Montana base material, usually ordered by top size. Driveway Gravel, or 3/4 road mix, carries enough fines and clay binder to pack hard under a roller.

Pit Run is unprocessed pit gravel for deep fill and raising grade under a base course. It is not a finished driving surface.

Stone Screenings, called crusher fines locally, bed pavers and flagstone and pack into pathway surfaces.

Delivery to Westby and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck tips the load on site in one pile.

That is the whole process.

Westby sits in Sheridan County, and delivery covers the town and the surrounding area. Coverage reaches Plentywood, Medicine Lake, Outlook, Reserve and Redstone as well.

If your site is out on a county road or a field approach, the truck still tips the load where it can safely reach.

Bulk loads are heavy and the ground decides a lot. On ground that is still holding frost or thawing out, a truck can cut ruts fast.

Timing the delivery to the ground matters as much as the material itself.

Ground and Conditions in Westby

This part of Montana is glacial till over shale, a mix of clay, gravel, sand and silt left by ice and glacial lakes. Much of it is heavy and slow to drain.

Coulee and river-bottom alluvium cuts down through it.

Flat ground plus heavy till means water sits. Snowmelt ponds on subsoil that is still frozen, and a semi-arid year gets broken by a few intense summer storms.

That combination is why a drainage layer earns its place under a base.

The working season is short. Frost is in the ground from late autumn into spring, and compaction waits for it to come out.

Chinook thaws cycle the surface without taking the frost fully out until spring.

Wind moves bare ground, coulees sheet and gully, and banks cut. Riprap and heavier stone hold those edges.

Plan the delivery around the season, not against it.
