Bulk Material Delivery in Cohasset, MN

Minnesota Rock Supply handles gravel and aggregate delivery in Cohasset, MN, and Class 5 is the base most of that work starts from. It is the Minnesota name for a compacted base course, and it goes under driveways, parking pads, shed floors and garage slabs.

Cohasset sits in Itasca County, where thin, stony till over bedrock shows up across much of the ground. That shapes what you order and how much of it you need.

Materials for Cohasset Projects

Coarse stone carries the slope, swale and bank work around here. Water runs off fast over rock and gathers in the hollows, so the stone you place at a bank edge or a culvert outlet has to hold against moving water and spring runoff.

RipRap is the heavy end of that work. It armours lakeshores, streambanks, culvert outlets and slopes against ice, wave action and runoff.

Railroad Ballast is a coarse Crushed Stone for track beds, hard standing and severe drainage. It suits a swale or a wet approach where you need open stone that will not hold water.

Drainage Rock is a 1 1/2 inch clear rock used in French drains, drywells, footing and foundation drains, downspout runs and sewer bedding. Clear means the fines are washed out, so water moves through it.

3/4 Clear Rock is the smaller clean stone. It goes into drainage beds, drive surfacing, construction entrances and trench backfill, and it is also the clean washed rock used under basement slabs and around footing drains.

Below the coarse stone, Class 5 is the standard Minnesota base course. It keeps its fines, so it binds and compacts into a firm surface for a drive or a pad.

Where you want a tighter surface on top, Driveway Gravel covers Class 2, the surfacing class in the same spec, sold as Class 2 granite or limestone at a 3/4 inch minus size.

Ground and Conditions in Cohasset

This is the shortest working season in the state. Frozen ground stops compaction from late autumn into April, and spring load limits run into mid-May on North zone roads.

That timing decides when a load is worth placing. Class 5 and other fines-bearing material need to be worked while the ground is open, so a delivery that lands on frozen ground waits until the thaw.

Water is the other half of it. Across the Iron Range, North Shore and the Superior Upland, water cannot soak into rock, so it runs off fast and gathers in the hollows and peat basins, and snowmelt is the heaviest flow of the year.

That is why clean, open stone matters at a bank, a swale or a culvert outlet. RipRap and clear rock let that fast water pass instead of holding it against the slope.
