Riprap, Stone and Soil Delivery in Libby, MT
Montana Rock Supply handles gravel and aggregate delivery in Libby, MT, from crushed base course for a shop pad to riprap for a bank that keeps moving. Each product page has a calculator, so you size the load before the truck rolls.
This is the wettest corner of the state, and the ground here shows it. Runoff comes off steep forested slopes and the streams run high into early summer.
Materials for Libby Projects
Coarse stone does the heavy work around here: slope, swale and bank protection where water arrives fast and leaves faster. Start at the coarse end and work down to the fines.
Riprap, also called armor rock, is the first choice for stream bank armoring, culvert outlets, coulee and ditch protection, and slope work against spring runoff. It is heavy, angular and built to hold ground in place.
#4 Crushed Stone covers heavy drainage, construction entrances and trench bottoms. It is coarse enough for open voids that let water move.
3/4" Crushed Stone works for drainage beds, pipe bedding and surfacing over a compacted base. Washed Rock, the clean 3/4, is the one for French drains, curtain drains and downspout runs, because the fines are washed out.
3/4 Crushed Base Course, or 3/4 minus, is the standard Montana base material for driveways, shop pads, parking areas and shed bases. For the finished driving surface, Driveway Gravel is the road mix, carrying enough fines and clay binder to pack hard.

Ground and Conditions in Libby
Base, driveway and paver work runs from breakup into late fall. Saturated spring ground and frozen winter ground both stop proper compaction, so timing a delivery matters as much as the material.
Across the Northwest forests, Flathead and Kootenai country, the ground is glacial till and outwash with deep lake silt and clay on the valley floors, gravel benches above, and thin stony soils over rock on the forested slopes.
That silt and clay drains slowly, and runoff off logged and burned slopes scours stream banks at spring high water. Winters here are wetter and a little milder than the rest of Montana, with heavy mountain snow, so the ground freezes and thaws repeatedly and gravel drives heave at breakup.
For a wet, slow-draining site, washed rock keeps the drainage path open while riprap and #4 stone armor the places water attacks. Crushed base course gives you the compacted surface over the top.
Questions from Libby Buyers
What stone should I use for drainage in Libby?
For a French drain, curtain drain, foundation drain or downspout run, use washed rock, also called drain rock or 3/4 clean, because the fines are washed out and water moves through it. For heavy drainage, trench bottoms and construction entrances, #4 crushed stone is the coarser option.
Fine drainage and trench bedding call for 3/8 inch crushed rock.
What should I have ready when the truck arrives?
Have the drop spot clear, reachable and big enough for a dump truck to tip a pile. The driver tips the load in one pile and does not spread it, so pick a spot you can work from.
