Gravel, Stone and Soil for Cook County, MN

Minnesota Rock Supply delivers gravel, stone and aggregate delivery in Cook County, MN, ordered online and tipped on site by dump truck. Class 5 is the base most drives and pads here are built on, and it is the name to use when you order.

This corner of the state sits on the Arrowhead, where thin stony till covers Precambrian bedrock and rock sits at or close to the surface. That changes what you need under a drive.

Materials delivered in Cook County

Class 5 is Minnesota's standard base course. County highway departments and cities write their own standards against the same class numbers.

Order it for driveways, parking pads, shed and garage bases, and road base.

Yards sell it as Class 2 granite, buff limestone or red limestone, and it is used for drive surfacing and paver base.

Clean stone carries the drainage work. Clear rock is washed with the fines taken out, which is what separates it from Class 5.

Granite fines bed pavers and flagstone, and black dirt handles lawns and planting beds.

Natural Pea Gravel covers walkways, play areas and exposed aggregate work, and Minnesota river rock handles decorative beds and dry creek beds. Each product page has a calculator for sizing a load.

Ground conditions across Cook County

Thin, stony till over Precambrian bedrock means rock sits at or close to the surface across much of the northeast. A base course laid over that thin soil moves with it, and the shallow cover over ledge lifts gravel drives, posts and slabs every spring.

Water cannot soak into rock, so it runs off fast and gathers in the hollows. Snowmelt is the heaviest flow of the year.

A clean washed stone under and around a slab gives that water somewhere to go, and drainage rock does the same for footing and foundation drains.

Short, steep streams cut hard after heavy rain and snowmelt, and wave action works the lakeshores. Riprap armours culvert outlets, streambanks and shorelines against that push.

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

Plan compaction work around that window.

Winters are long and severe, and frost reaches rock in places. The Minnesota Residential Code footing table sets 5 feet for its Zone I counties, a footing depth the building official sets.

Choosing the right material

Lake County shares the same region and the same ground region as Cook County: thin, stony till over Precambrian bedrock, with rock at or close to the surface. The ground is the same, so the same base and drainage choices carry over.

Class 5 remains the base course on both sides, and the drainage answer is the same clean washed stone. Because the soil depth over ledge is similar, expect the same shallow cover and the same spring movement under slabs and posts.
