Bulk Aggregates for Patios in Corvallis, MT

Montana Rock Supply brings gravel and aggregate delivery in Corvallis, MT to patios, walkways, drives and shop pads. Crushed base course is the material that carries the load, and it is what most local work starts from.

This part of Ravalli County sits on ground that ranges from silt and clay to river gravel, so the right material depends on what is under your project.

Ground and Conditions in Corvallis

Across the Western intermontane valleys, lake-bed silt and clay drain slowly and stay soft well into spring. Gravel outwash beside the rivers drains fast, so two sites a short drive apart can behave very differently.

A thin base over that silty ground is where patios go wrong. The slab or pavers rock, joints open, and edges settle out of line after a wet spring.

The fix is a base with enough fines and angular faces to lock together and shed water rather than hold it. Crushed base course, sold locally as 3/4 minus, does that under flatwork and pavers.

Snowmelt off the surrounding ranges keeps water moving through May and June, so drainage under and around a patio matters as much as the surface. Washed rock carries that water away instead of trapping it.

Valley ground has to dry out before it will compact, which makes the working season a real constraint. Cold overnight freezing and midwinter thaws also cycle the ground and heave gravel surfaces.

Materials for Corvallis Projects

Bedding under pavers and flatwork is where the wrong pick shows up first. The bedding layer has to sit flat, stay put, and let water move, or the surface above it will not stay true.

Washed sand is the standard bedding sand under pavers and flatwork, and it also acts as concrete sand. Mason sand is finer and goes to brick and block work and paver joints.

Crusher fines, which Montana yards call screenings, bed flagstone and pavers and surface packed pathways. Below either one, crushed base course builds the structural layer that carries the load.

For drainage, washed rock is the clean stone for French drains, curtain drains, foundation drains and downspout runs. Washing the fines out is the point, because clean stone passes water instead of holding it.

Natural Pea Gravel suits walkways, play areas and dog runs where rounded stone is wanted. River rock and large river rock handle decorative beds, borders and dry creek beds, and riprap armors stream banks, culvert outlets and ditches against spring runoff.

Topsoil and garden soil rebuild ground that is too thin or too stony for planting, and fill dirt raises grade before a base course goes down. Shredded mulch holds on slopes and in open ground better than nuggets.

Frequently Asked Questions

Common questions about gravel and aggregate delivery in Corvallis, MT

What gravel is best for a driveway in Corvallis?

Crushed base course, sold locally as 3/4 minus or 3/4 crushed base course, is the standard Montana base material for drives. Road mix, also called 3/4 road mix or driveway gravel, carries enough fines and clay binder to pack hard as a driving surface. Pit run is unprocessed pit gravel for deep fill and sub-base, not a finished drive.

How much material will my project need?

Quantities are ordered by the ton or by the yard, so you decide the unit that suits your project. Each product page has a calculator you can use to size the load before you check out. Order the quantity you need and pick a delivery date at checkout.

Where will the material be placed?

Wherever you tell us, as long as the truck can safely reach it. Mark the spot before the delivery and someone should be on site to point the driver to it. If nobody can be there, leave clear instructions when you order and we will follow them.
