Materials for Hardin Projects
Drainage is where a lot of Hardin work starts. Water that sits on gumbo clay has nowhere to go, so it needs a path out before anything else goes in.
Washed rock is the clean drainage stone for that job. The fines are washed out so water moves through instead of stacking up.
Use it in French drains, drywells, curtain drains, foundation drains and downspout runs. Order it as Washed Rock, or ask for 3/4 clean.
Size drives the rest of the list. Coarse stone moves water and carries weight; finer stone beds and tops.
- Riprap for coulee and ditch protection, culvert outlets and slope work against spring runoff. Heavy, coarse armor rock.
- 3/4" Crushed Stone for drainage beds, pipe bedding and construction entrances. Also called 3/4 inch rock or 3/4 clean crushed.
- 3/4 Crushed Base Course for driveways, shop pads, parking areas and shed bases. Locally that is 3/4 minus, and it packs hard.
- Stone Screenings for paver and flagstone bedding and packed pathways. Montana yards say crusher fines.
- 3/8" Natural Pea Gravel for walkways, play areas and dog runs where rounded stone suits better than sharp.
A driveway surface is a different material from the base under it. Road mix, sold locally as 3/4 road mix or driveway gravel, carries enough fines and clay binder to pack hard.
Order it as Driveway Gravel.
Where native clay or gravel will not grow anything, Top Soil and garden soil go over the top. Lawns, grading and bed prep take screened topsoil.
Delivery to Hardin and the Surrounding Area
Montana Rock Supply covers Hardin and the rest of Big Horn County, including Crow Agency, Busby, Lodge Grass, Wyola and St. Xavier.
The order is placed online, and a dump truck tips the load on your site.
Quantities are ordered by the ton or by the yard. Each product page has a calculator to size the load, and you pick a delivery date at checkout.
Have the drop spot clear and reachable before the truck arrives. The load comes off the back in one pile, so the ground you want it on is the ground it lands on.
Ground and Conditions in Hardin
Across the Eastern plains, Missouri Breaks and badlands, the driver is bentonite-rich gumbo clay weathered off marine shale. It swells and turns greasy when it wets up, then cracks open as it dries.
Water sits on the surface instead of soaking in.
That is why unsurfaced ground goes soft and why cloudbursts run straight off into the coulees. A drive on bare gumbo pumps and ruts under a truck.
A compacted crushed base course gives you a working surface that sheds water rather than holding it. Where a drain has to carry water away, the drainage layer is washed stone, not a fines-bearing material.
Work follows dry ground. Spring breakup and heavy rain make gumbo roads impassable, so midsummer and early autumn are the dependable window for a delivery.
Cold, dry winters bring deep frost and wide day-to-night swings, and ground that thaws on a chinook afternoon and refreezes overnight heaves gravel roads and opens up drives.
