3/8 Inch Crushed Rock for Patios in Shelby, MT
Montana Rock Supply handles gravel and aggregate delivery in Shelby, MT for two kinds of buyers: contractors building pads and drives, and homeowners finishing a yard. Both need the same thing, the right material under the surface.
If you are bedding pavers or a patio here, crushed base course is the material that carries the load. It is sold locally as 3/4 minus, and it is the standard base across the Hi-Line and the northern glaciated plains.
Ground and Conditions in Shelby
Toole County sits on glacial till over shale, a mix of clay, gravel, sand and silt left by the ice and by glacial lakes. Much of it is heavy and drains slowly.
A thin base shows its failure fast on ground like that. The surface shifts, water sits, and pavers rock out of line within a season.
The fix is a base that spreads the load and a drainage layer that moves water away. On flat ground over heavy till, water needs somewhere to go before it can leave on its own.
Frost is in the ground from late autumn into spring, and compaction waits for it to come out. Chinook thaws cycle the surface without taking the frost fully out until spring.
Wind on bare ground and sheet erosion in the coulees are the other local drivers. Bare subsoil moves once it dries and the wind picks up.
Materials for Shelby Projects
Bedding under pavers and flatwork is where the material choice decides whether the surface stays flat. The base goes down first, and everything above it follows that base.
3/4 Crushed Base Course, also called 3/4 minus, is the standard Montana base material. It is used under driveways, shop pads, parking areas and shed bases, and it is usually ordered by top size.
Under a patio, it is the layer that carries the pavers. Stone Screenings, which Montana yards call crusher fines, go on top of it as the bedding course.
Screenings bed pavers and flagstone and surface packed pathways.
Sand is the other bedding option. Washed Sand levels and beds under flatwork and pavers, and it doubles as concrete sand.
Mason Sand is used for brick and block work and for paver joints.
Where a patio meets a downspout or a drain line, Washed Rock handles the water. Washing the fines out is the whole point, so the stone stays open and water passes through.
For the surface itself, 3/8" Crushed Stone gives a tight topping over a compacted base. 3/4" Crushed Stone is the coarser option for drainage beds and pipe bedding.
Delivery to Shelby and the Surrounding Area
Quantities are ordered by the ton or by the yard, and each product page has a calculator to size the load. Choosing between the two comes down to how the material is measured and how you want to compare it.
You order online, pick a delivery date at checkout, and a dump truck tips the load in one pile on site. Bulk delivery to a Shelby address works the same way whether the job is a patio or a shop pad.
Montana Rock Supply delivers across Toole County, including Sunburst, Kevin, Sweet Grass, Ledger and Oilmont.
Questions About Gravel and Bedding in Shelby
What gravel is best for a driveway in Shelby?
Start with crushed base course, sold here as 3/4 minus, because it compacts into a hard driving surface. If you want a smoother finished lane, road mix, also called 3/4 road mix, carries enough fines and clay binder to pack hard under a roller.
Pit run is unprocessed pit gravel for deep fill and raising grade, not a finished driving surface.
How much material will my project need?
Each product page has a calculator, and quantities are ordered by the ton or by the yard. Work out the area you are covering and the depth you want, then let the calculator turn that into a quantity.
Ordering by the ton and ordering by the yard are both available, so pick whichever matches how you measured.
