Bulk materials for Columbia Falls projects
Start with the job underneath the material. A driveway needs a compacted base, a drain needs clean stone with open spaces for water movement, and a decorative bed needs a finish rock that stays where it is placed. For a specified base, 3/4 Crushed Base Course matches MDT Section 701 crushed base course, Grade 5A, also called 3/4 minus, crushed base or 5A.
Washed Rock is also known as 3/4 clean or drain rock. Its washed, open structure fits drain trenches where water needs a route through the stone. Yellowstone River Rock, also called river rock or round rock, is suited to visible coverage where a rounded finish is wanted.
Ground, frost and drainage planning in Flathead County
Montana ground conditions change from valley gravel that sheds water to dense clay that turns slick when wet and hard when dry. Check the soil at the actual work area before deciding on a base, drain location or final grade. Keep surface water moving away from structures, and use clean drainage stone around drain pipe where the plan calls for it.
The statewide frost-depth guide is 48 inches. Confirm frost requirements, footing depth and permit needs with the local building department before excavation. Driveways and pads need a firm base placed in controlled lifts and compacted as work progresses, rather than dumping the full depth and trying to compact it all at once.
For many light-duty driveway or patio-base jobs, crews use a compacted base depth in the 4 to 8 inch range, with more depth where ground conditions, traffic or project plans require it. Grade the finished surface to shed water, because standing water weakens a base and creates soft spots during freeze and thaw cycles.

Use ZIP code 59912 when entering the delivery location. Before setting a delivery date, check the truck route for overhead clearance, narrow approaches, soft shoulders, tight turns and a firm unloading area. Mark the dump location clearly and keep vehicles, materials and equipment out of the truck's turning path.
Distance, weather and pass conditions affect delivery planning. Spring road limits on county roads can hold full trucks for weeks, so book ahead when seasonal restrictions are in effect. A dry, accessible unload area gives the driver room to place material where the crew needs it.
