3/8 Inch Crushed Rock for Patios in East Helena, MT
Montana Rock Supply handles gravel and aggregate delivery in East Helena, MT, and the working season here is short. Base, driveway and paver work on the valley floors runs from late spring into early autumn, so timing a load matters as much as the material itself.
Start with crushed base course, also called 3/4 minus, for anything that carries weight. From there, the right stone and sand depend on what you are building.
Ground and Conditions in East Helena
Across the Southwest and south-central mountain valleys, ground on the basin floors is often gravelly alluvium and outwash. Clay-rich basin fill shows up in places, and the ranges that ring the valleys carry thin, stony soils over rock.
That mix decides how a patio behaves. Where the ground under a paver or flagstone bed is not built up properly, the surface moves and the joints open.
Snowmelt off the Great Divide and sudden summer thunderstorms falling on dry ground both put water into the ground fast. Gravel basin fill takes water readily.
Clay-rich fill does not, and water that cannot pass sits.
Placement follows from that. A bed set on a firm, uniform layer holds its lines better than one laid on soft or uneven ground.
Materials for East Helena Projects
Bedding is what makes a patio or walkway last. The material under the surface has to sit flat and stay put, and the joints between units need a fill that locks them without pushing them apart.
Stone Screenings, which yards around here call crusher fines, is the standard bed for pavers and flagstone. It packs into a firm, flat surface and also works as a packed pathway finish.
Washed Sand is the leveling and bedding choice under flatwork and pavers, and it doubles as concrete sand. Mason Sand suits brick and block work, paver joints and play areas.
Below the bed, 3/4 Crushed Base Course is the Montana base material, usually ordered by top size as 3/4 minus. It is what drives, shop pads, parking areas and shed bases sit on.
For a tighter topping over a compacted base, 3/8" Crushed Stone gives fine drainage, trench bedding and a neat surface. 3/4" Crushed Stone is the size up, used over a compacted base and in drainage beds and pipe bedding.

What gravel is best for a driveway in East Helena?
Crushed base course, sold locally as 3/4 minus, is the base for drives, shop pads and parking areas. For the driving surface itself, road mix carries enough fines and clay binder to pack hard.
Pit run is unprocessed pit gravel for deep fill and raising grade, not a finished driving surface. Order 3/4 minus as 3/4 Crushed Base Course.
How much material will my project need?
Measure the area you are covering and note the depth you plan to build to. Each product page has a calculator you can use to work out the quantity, and you can order by the ton or by the yard.
For a patio bed, base and surface are separate quantities, so size each one on its own.
