Bulk Aggregates for Pathways in Polson, MT

Montana Rock Supply handles gravel and aggregate delivery in Polson, MT, and crushed base course is where most ground work starts here. Northwest Montana ground is often thin and stony over rock, with silt and clay on the valley floors.

Base, driveway and paver work runs from breakup into late fall. Saturated spring ground and frozen winter ground both stop proper compaction, so timing matters as much as the material.

Ground and Conditions in Polson

Across the Northwest forests, Flathead and Kootenai country, glacial till and outwash sit above deep lake silt and clay on the valley floors. Gravel benches and thin stony soils over rock show up above them.

A thin base on ground like that shows its failure fast. The surface ruts and pumps, edges break away, and the stone works down into soft clay instead of holding.

This is the wettest corner of the state, and silt on the valley floor drains slowly under all of it. Spring runoff off steep forested ground keeps the ground saturated into early summer.

Winters here are wetter and a little milder than the rest of Montana, with heavy mountain snow. The ground freezes and thaws repeatedly instead of locking up once, and gravel drives heave at breakup.

That freeze and thaw cycle is why a soft subgrade needs bulk fill before anything goes over it. Riprap and washed rock handle the water moving at stream banks and culvert outlets.

Materials for Polson Projects

Crusher fines, which Montana yards call screenings, are the material that makes paths and walkways work. The fines bind the surface so it packs and stays walkable.

Stone Screenings bed pavers and flagstone and surface packed pathways. Walkway Gravel gives garden paths and walkways a finer surface than a drive.

Crushed base course, also called 3/4 crushed base course or 3/4 minus, is the standard Montana base material. It goes under driveways, shop pads, parking areas and shed bases.

3/4 Crushed Base Course is ordered by top size. Driveway Gravel, called road mix here, carries enough fines and clay binder to pack hard under a roller.

Screenings and washed sand both bed flatwork. Washed Sand levels and beds under pavers, and mason sand handles brick, block and paver joints.

Drainage work calls for rock with the fines washed out. Washed Rock, or 3/4 clean, is what French drains, curtain drains and downspout runs use.
