What is Class 5 and what is it used for in Goodhue County?

Class 5 is a crushed aggregate base with fines. County highway departments and cities write their own standards against the same class numbers. In Goodhue County it goes under driveways, parking pads, shed and garage bases and road base, where it binds and compacts.

How deep should a gravel driveway base be in Goodhue County?

That depends on your ground. On the tight prairie till around Kenyon, Wanamingo and Dennison, water drains slowly, so the base does more work. On the thin silty soils over rock in the bluff country, frost lifts slabs and walks. Frost depth here is 3 feet 6 inches, a footing depth the building official sets, not a gravel base depth.

Goodhue County, MN Aggregate and Rock Delivery

Minnesota Rock Supply brings gravel, stone and aggregate delivery in Goodhue County, MN. Class 5 is the base course most of this work starts from, a crushed rock with fines that binds under driveways, parking pads, shed bases and road base.

Goodhue County spans two different grounds. You get Driftless bluff and karst country around Red Wing, Cannon Falls, Zumbrota and Pine Island, and prairie till at Kenyon, Wanamingo and Dennison.

Materials Delivered in Goodhue County

Class 5 is the standard Minnesota base course.

Class 2 is the surfacing class in the same section, a 3/4 inch crushed aggregate with fines. Yards sell it as Class 2 granite, buff limestone or red limestone.

3/4 Clear Rock is also sold as foundation rock. It is the clean washed rock used under basement slabs and around footing drains, including the gas-permeable layer under the passive radon system Minnesota requires in new homes.

Washed Sand is bedding and levelling sand, also sold as concrete sand. Mason Sand covers brick and block work, paver joints, sandboxes and play areas.

For decorative work, Minnesota River Rock fills borders, dry creek beds and rock mulch around foundations. Large River Rock handles heavier decorative work and light shoreline protection.

Ground Conditions Across Goodhue County

Goodhue County spans two ground regions, so conditions change with where you are building.

In the Driftless bluff and karst country around Red Wing, Cannon Falls, Zumbrota and Pine Island, loess sits over residual soil on Paleozoic limestone, dolostone and sandstone. It is thin on ridge tops, deep in the valleys, with rock outcrops on the bluffs.

This is karst ground, worked by groundwater into sinkholes, springs and caves. Water runs off steep slopes fast and disappears into sinkholes and fractures rather than soaking in evenly, so a downspout run aimed at a sinkhole goes straight to groundwater.

In the prairie till around Kenyon, Wanamingo and Dennison, gray calcareous Des Moines lobe till sits under deep black prairie soil. The till is loamy to clayey and carries shale brought down from the Dakotas, with a hummocky pothole surface over much of it.

Tight till and almost no fall drain slowly. Closed pothole basins hold water until it is drained or evaporates, and the thaw plus early summer thunderstorms are when yards and drives are worst.

Frost depth is 3 feet 6 inches, or 42 inches, the depth the Minnesota Residential Code footing table sets for its Zone II counties. That number is a footing depth set by the building official, and heaving is worst on the tight, shale-rich till where water cannot drain away before it freezes.

Erosion follows the ground. On the bluff side you see rill and gully erosion on steep loess slopes, bluff and roadcut slumping, and flash flooding in the valleys after heavy rain.

On the till side, sheet, rill and gully erosion shows up on bare cropland and graded lots after heavy summer storms.

The working season runs from the thaw into late autumn, one of the longer seasons in the state. Spring load limits go up on Southeast zone roads in early March and come off in April.

Choosing the Right Material

Dakota County sits in the Twin Cities metro and packs several different grounds inside one short drive. That includes the Anoka sand plain, Grantsburg lobe till through the western and northern suburbs, and Platteville limestone over St.

Peter sandstone in the bluffs.

That range is wider than Goodhue County's two grounds, so what a base sits on changes faster there than it does here. A sandy ground and a limestone bluff shelf do not drain or compact the same way.

Rice County and Dodge County both sit on the same prairie till as Goodhue County's western side: gray, calcareous Des Moines lobe till under deep black prairie soil. The ground is the same, so the base and drainage choices you make there carry over.
