Gravel and Aggregate Delivery in Helena, MT

Montana Rock Supply brings gravel and aggregate delivery in Helena, MT, with crushed base course leading the list. This is the standard Montana base material, ordered by top size as 3/4 minus.

It goes under drives, shop pads and parking areas.

The same trucks carry pit run, road mix, washed rock, sand, topsoil and decorative stone. You order online and a dump truck tips the load on site.

Materials for Helena Projects

Crushed base course is the compacted base for a driveway, a shop pad, a parking area or a shed base. It is also called 3/4 crushed base course, 3/4 minus or crushed base.

Order it from 3/4 Crushed Base Course.

Pit run is unprocessed pit gravel. It goes in deep fill, raising grade and sub-base under a crushed base course, not as a finished driving surface.

Order it from Pit Run.

Road mix is the surfacing for a drive or a county-style lane. Montana road mix carries enough fines and clay binder to pack hard under a roller.

Order it from Driveway Gravel.

Washed rock, also called drain rock or 3/4 clean, has the fines washed out. That is the point of it in French drains, curtain drains, foundation drains and downspout runs.

Order it from Washed Rock.

Crusher fines, which Montana yards call screenings, bed pavers and flagstone and surface packed pathways. Order them from Stone Screenings.

Sand and soil round out a site. Washed sand beds flatwork and pavers, mason sand goes into brick and block work, and screened topsoil covers thin or stony native ground before seed.

Ground and Conditions in Helena

Snowmelt off the Great Divide, sudden summer thunderstorms on dry ground and irrigation ditches crossing valley floors all put water on the ground here. Where that water goes decides what a drive needs.

Across the Southwest and south-central mountain valleys, the ground runs from gravelly alluvium and outwash on the basin floors to clay-rich basin fill in places. Gravel basin fill takes water readily.

Clay-rich fill does not.

That split matters at the base. A clean, open material like washed rock moves water away, while a fines-bearing base course packs tight and holds a surface together.

Match the layer to the job.

Frost heave is a normal condition here, not only a spring event. Hard overnight freezing with a daytime thaw runs through much of the year.

The figure commonly used for Helena is about 48 inches, and the local building department sets footing depth.

The working season is short. Base, driveway and paver work runs from late spring into early autumn on the valley floors.

Spring runoff and bank scour drive the erosion work, so riprap and large river rock go where water concentrates.
