St. Louis County, MN Gravel and Landscape Rock Delivery
Minnesota Rock Supply handles gravel, stone and aggregate delivery in St. Louis County, MN.
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. Order Class 5 early and plan the pour around the thaw.
Class 5 is the base course most Minnesota drives and pads are built on.
Materials Delivered in St. Louis County
Class 5 is the standard Minnesota base course.
Use Class 5 for driveways, parking pads, shed and garage bases, and road base. It compacts into a firm, bound surface that sheds water at the crown.
Class 2 is the surfacing class in the same spec. It is a tighter 3/4 inch crushed aggregate with fines, sold as Class 2 granite, buff limestone or red limestone.
Order Driveway Gravel to top an existing drive or finish over a compacted base.
Clean stone has the fines washed out, which is what Minnesota calls clear rock. It drains instead of binding, so it belongs under and around things rather than under a drive.
Round washed stone covers decorative ground. Minnesota River Rock suits beds, borders and dry creek beds, and Large River Rock takes heavier decorative work and light shoreline protection.
For sand and fill, Mason Sand beds brick and block and fills sandboxes, while Fill Dirt raises grade before a Class 5 course goes down.

Ground Conditions Across St. Louis County
Across the Iron Range, North Shore and the Superior Upland, the ground is thin, stony till over Precambrian bedrock, with rock at or close to the surface across much of the northeast. A thin base over that ledge shows every weak spot by spring.
Water cannot soak into rock, so it runs off fast and gathers in the hollows and peat basins. Red clay slopes shed water almost as badly.
Snowmelt is the heaviest flow of the year, and it finds any base that was not built to move water.
The fix is a compacted Class 5 course over clean drainage stone where water collects. Clear rock under a slab and around footing drains gives meltwater somewhere to go instead of lifting the surface above it.
Long, severe winters drive frost deep. The Minnesota Residential Code footing table sets 5 feet (60 inches) for its Zone I counties, and shallow soil over ledge lifts slabs, posts and gravel drives every spring.
That is a footing depth set by the building official, not a target for a gravel base.
Choosing the Right Material
Aitkin County sits on moraine and outwash country: drumlin fields, broad sand plains and peat in the low ground. That sandy loam over gravel drains far better than the thin till over bedrock here, so a base there needs less drainage stone beneath it.
Itasca County shares this ground region. The till, the bedrock and the peat basins are the same, so the same Class 5 base and clean stone drainage apply.
Koochiching County spans more than one zone, reaching into the Red River Valley and the northern lake plain. Where that ground turns to lake plain, drainage behaves differently than it does over the rock here.
