Riprap and Bulk Aggregates for Moore, MT

Riprap and Bulk Aggregates for Moore, MT

If your driveway is soft, your ditch is cutting deeper, or your shed pad needs a base, gravel and aggregate delivery in Moore, MT covers it. Montana Rock Supply delivers bulk material by the ton to sites in Fergus County.

Most drives and pads around here start with crushed base course, the local name for 3/4 minus. On the clayey and silty ground this region runs to, that base is what keeps a surface from rutting when it wets up.

Materials for Moore Projects

Slope, swale and bank protection starts with coarse stone. Riprap, also called armor rock or shot rock, is the heavy end of that work.

It goes on stream banks, culvert outlets, coulees and ditches where spring runoff arrives fast.

Large river rock handles the smaller version of the same job. It works in dry creek beds, at splash points under downspouts, and on decorative edges where rounded stone is wanted.

From there the sizes step down. 3/4 inch crushed rock, often asked for as 3/4 clean crushed, suits drainage beds, pipe bedding and construction entrances.

Below it, 3/8 inch crushed rock gives fine drainage and trench bedding.

Washed rock, or drain rock, is clean stone with the fines washed out. That is the point of it in French drains, curtain drains and foundation drains, where water has to move through rather than sit.

For the driving surface itself, road mix, also called 3/4 road mix or driveway gravel, carries enough fines and clay binder to pack hard. Pit run is unprocessed pit gravel for deep fill and raising grade, and it is not a finished driving surface.

Delivery to Moore and the Surrounding Area

Montana Rock Supply delivers bulk aggregate across Fergus County, including Moore, Lewistown, Denton, Winifred, Roy and Grass Range. You order online and pick a delivery date at checkout.

Quantities are ordered by the ton or by the yard. Each product page has a calculator to help you size the load, and the material arrives on a dump truck that tips it in one pile at your site.

Because this is open benchland country, a date that fits the season matters as much as the material. Once you have your quantity and your date, the rest is handled.

Ground and Conditions in Moore

Work here runs from breakup into autumn, and the benchland dries out quickly once spring runoff is past. Timing a delivery to that window keeps a loaded truck off ground that is still soft underneath.

Across the Central Montana benchlands and island ranges, the soils are deep silt and clay on the benches, with gravelly terraces and shallow stony ground elsewhere. Clay subgrades soften as soon as they wet up, so a drive on bare clay loses shape fast.

Spring snowmelt running over ground still frozen below, plus heavy summer thunderstorms on open benchland, drive the erosion on this side of the state. Wind moves soil on open farmland, silt and clay slopes gully, and banks cut along the rivers.

Winters here are cold inland winters cut by chinooks, so the ground freezes hard, thaws and refreezes. Gravel roads soften and rut with each cycle.

In Great Falls the figure commonly used for frost depth is about 42 inches, with deeper figures in the ranges, and the local building department sets footing depth. That is a footing number, not a base number.

Frequently Asked Questions

Common questions about gravel and aggregate delivery in Moore, MT

What stone should I use for drainage in Moore?

It depends on the job. Washed rock, also called drain rock or 3/4 clean, is the choice for French drains, curtain drains and foundation drains, because the fines are washed out and water passes through. For a drainage bed or pipe bedding, 3/4 inch crushed rock or 3/8 inch crushed rock works. Riprap is what you want for a bank, swale or culvert outlet taking fast runoff.

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, with nothing overhead and room for a dump truck to tip its load. The driver tips the material in one pile, so pick a spot you can work from. Have your quantity and delivery date set from checkout, and make sure the ground at the spot can hold a loaded truck.

How is the material measured?

You can order by the ton or by the cubic yard, whichever suits how you plan the job. If you tell us the area you are covering and the depth you want, we will work the quantity out with you rather than leaving you to guess.
