What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular faces from a crusher, so it interlocks and stays put under a base or in a drainage bed. Natural Pea Gravel is rounded and washed, about 3/8 inch, and it flows rather than locks. Use crushed stone where structure matters and Natural Pea Gravel for walkways, play areas and dog runs.

Should I order material by the ton or by the yard?

Both work, and the choice usually comes down to how you measured the job. Order by the ton when you have a weight in mind, or by the yard when you are working from volume. Each product page has a calculator to size the load either way.

Which stone is best for drainage in Ravalli County?

Washed rock is the clean drainage stone, with the fines washed out so water moves through it. Use it for French drains, curtain drains and downspout runs. For heavier work, 3/4 inch crushed rock handles drainage beds and pipe bedding, and riprap armors banks and culvert outlets against high water.

Materials delivered in Ravalli County

Base material in Montana is specified as crushed base course. The MDT Standard Specifications cover it under Section 701.02.4, with grades named by nominal top size.

City and county work is often written against Section 02235 of the Montana Public Works Standard Specifications. County road standards call sizes out the same way.

Smaller sizes fill in the rest: 3/4 inch crushed rock for drainage beds and pipe bedding, 3/8 inch crushed rock for trench bedding, and Natural Pea Gravel for walkways and play areas.

Sand and soil round out an order. Mason sand for block work and paver joints, washed sand for bedding under flatwork, garden soil for raised beds, and shredded mulch for beds and tree rings.

Ground conditions across Ravalli County

Across the Western intermontane valleys, lake-bed silt drains slowly and stays soft well into spring. River gravels beside it drain fast.

That split decides what goes under a drive.

The working season runs from breakup into late fall, long enough by Montana standards. Silty valley ground has to dry out before it will compact, so timing a delivery matters as much as the material.

High water brings bank scour, gully cutting in silt benches, and heavy runoff off burned ground after a fire summer. Riprap and large river rock armor those edges.

Valley winters freeze hard overnight, and chinook thaws cycle the ground and heave gravel surfaces. Frost depth figures are set by the local building department, which also sets footing depth.

On the benches and mountain fronts, ground turns shallow and stony. Screened topsoil and garden soil carry a lawn or a bed where native ground will not.

Choosing the right material

Missoula County sits in Glacier Country and spans more than one ground region, taking in Western intermontane valleys plus Northwest forests, Flathead and Kootenai country. Ravalli County is Western intermontane valleys ground.

That means ground in the forested country differs from the silt and river gravel here. Where timber ground and forest soils take over, drainage and base choices shift with them.

Within the Western intermontane valleys ground the two counties share, the soil and drainage picture is the same.
