Crushed Base Course Delivery for Lewistown, MT

Montana Rock Supply brings gravel and aggregate delivery in Lewistown, MT to yards and job sites across Fergus County. Start with crushed base course, the 3/4 minus material that carries drives, shop pads and parking areas here.

On the Central Montana benchlands and island ranges, clay subgrades soften fast once they wet up. A pad built on bare ground moves.

Fill and base course put stable material under the work instead.

Delivery to Lewistown and the Surrounding Area

Order online and pick your quantity by the ton or by the yard. Each product page has a calculator if you want to size the load before you check out.

Choose a delivery date at checkout, and a dump truck tips the material on site in one pile. The driver does not spread or place it, so plan where that pile should sit.

Delivery covers Lewistown and the rest of Fergus County, including Moore, Denton, Winifred, Roy and Grass Range. If your site is on a county lane or out on the bench, the truck still tips where the ground allows.

Materials for Lewistown Projects

Raising grade and building pads come first in this country. Get the sub-base right and the surface material has something to sit on.

Fill Dirt is bulk fill for backfill and for bringing a low spot up to grade before any base course goes down. It is the first layer, not the finished one.

Pit Run is unprocessed pit gravel for deep fill and sub-base under a crushed base course or a road mix surface. It is not crushed and it is not a driving surface.

For the surface itself, 3/4 Crushed Base Course is the standard Montana base, and Driveway Gravel, also called 3/4 road mix, packs hard under a roller for a drive or a county-style lane.

Drainage is the other half of the job. Washed Rock, or 3/4 clean, goes in French drains, curtain drains and downspout runs where washing the fines out is the point.

For bedding and tight surfaces, Stone Screenings bed pavers and flagstone and pack into pathway surfaces. Yards here call them crusher fines.

Ground and Conditions in Lewistown

Across the Central Montana benchlands and island ranges, the ground runs to deep silty and clayey prairie soils, with gravelly terraces and shallow stony ground on the island ranges. That clay is the part that shapes a base.

Clay subgrades soften as soon as they wet up. Spring snowmelt then runs across ground that is still frozen underneath, and heavy summer thunderstorms drop water on open benchland fast.

An under-built base fails on that ground. Fill and sub-base lift the finished surface above the wet zone and give the crushed base course something firm to sit on.

Wind erodes open farmland, silt and clay slopes gully, and banks cut along the region's streams. Riprap armors culvert outlets, coulees and slopes against spring runoff.

Work runs from breakup into autumn, and the benchland dries out quickly once spring runoff is past. Cold inland winters cut by chinooks freeze the ground hard, thaw it and refreeze it, so gravel roads soften and rut through the cycles.

Questions About Material in Lewistown

What is the best base under pavers in Lewistown?

Start with crushed base course as the structural layer, then bed the pavers in crusher fines, which yards here also call stone screenings. On the clay soils common to the Central Montana benchlands and island ranges, the base course is what keeps the surface from moving when the ground wets up.

Order both by the ton or the yard.
