Pea Gravel and Bulk Aggregates for Grand Marais, MN

Looking for gravel and aggregate delivery in Grand Marais, MN? Minnesota Rock Supply sells bulk material online and delivers it to your site.

Class 5 is the base course most Minnesota drives and pads start from, and it is the name to use when you order.

Up here the ground is thin and stony over bedrock, so water has nowhere to soak in. That shapes what you order as much as the job itself does.

Materials for Grand Marais Projects

Water that cannot soak into rock has to be carried away, and that is what washed stone does. Clear rock is Minnesota for washed with the fines taken out, so the voids stay open and water moves through instead of sitting.

Start coarse. Drainage Rock is usually a 1 1/2 inch clear rock here, and it is the size for French drains, drywells, footing drains and downspout runs.

3/4 Clear Rock does the same work at a smaller size. It suits drainage beds, trench backfill and the clean layer under a slab, including the gas-permeable layer a passive radon system needs.

3/8" Crushed Stone is the fine end: pipe bedding and a thin topping over a compacted base. #57 Stone and #67 Stone are national size numbers for drainage and concrete work.

Where the ground has to hold a load instead of drain, the fines-bearing material is the right call. Class 5 keeps its fines, binds and compacts into a base for driveways, parking pads, shed and garage bases and road base.

Driveway Gravel finishes over a compacted base or tops an existing drive. Crusher Run is crushed rock with the fines left in for the same binding job.

For bedding and finishing: Granite Fines bed pavers and flagstone, Washed Sand levels under slabs and pavers, and Mason Sand handles brick and block work.

On the surface side, 3/8" Natural Pea Gravel covers walkways and play areas, and Minnesota River Rock works as decorative stone around foundations.

Where a slope meets water, RipRap armours shorelines, culvert outlets and streambanks against ice, wave action and spring runoff.

Ground and Conditions in Grand Marais

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 your delivery date more than anything else. Material that lands on ground still holding frost cannot be worked, so plan around the thaw rather than against it.

Water is the other half of it. Rock will not take water, so melt and rain run off fast and gather in the hollows, and snowmelt is the heaviest flow of the year.

A drainage layer of clear rock gives that water somewhere to go.

Frost also lifts what sits on shallow soil over ledge. The Minnesota Residential Code footing table sets 5 feet for its Zone I counties, and that figure belongs to those counties, not to Cook County.
