Bulk Aggregate Delivery Across Pennington County, MN
Planning a driveway, a parking pad, a patio base or a drainage run starts with the material under it. Minnesota Rock Supply handles gravel, stone and aggregate delivery in Pennington County, MN, ordered online and tipped on site by dump truck.
Class 5 is the base course most of that work begins with here, and it is the name to use when you order. It is also called Class 5 gravel, Cl 5 or Class 5 aggregate base.
Materials Delivered in Pennington County
Class 5 is the standard Minnesota base course.
That is how base material is named and specified in Minnesota.
Order Class 5 for driveways, parking pads, shed and garage bases and road base.
Class 2 is the surfacing class in the same spec, a tighter 3/4 inch crushed aggregate with fines. Yards sell it as Class 2 granite, buff limestone or red limestone, and it goes on drive surfacing and paver base.
Around it sit the supporting materials: clean stone for drainage, fines for bedding, sand for setting, and soil for the ground beside the work.
Choosing the Right Material
Pennington County sits on the flat bed of glacial Lake Agassiz, deep silt and clay settled out in still water. Marshall County shares that same ground, so the base and drainage reasoning there is the same as here.
Beltrami County spans more than one zone, reaching into North central lakes, moraine and outwash country as well as this lake plain. Polk County does the same, and its moraine and outwash ground is coarser and better drained than lake clay.
Where the ground is sandy outwash rather than clay, water moves through the subgrade instead of sitting on it. That changes the drainage layer you need under a slab or a footing drain.
On lake clay the water has nowhere to go, so clean open stone carries it. Use 3/4 Clear Rock or Drainage Rock for that, and keep fines-bearing material out of it.
For a surface that has to bind and compact, the fines belong in the mix. Crusher Run is crushed rock with the fines left in, and Minnesota yards more often sell it by class or by a minus size.
Ground Conditions Across Pennington County
Across the Red River Valley and the northern lake plain, the ground is weak, frost susceptible lake sediment, and it is a poor aggregate source. Usable sand and gravel sit in the beach ridges and river terraces instead.
A thin base over that clay shows its failure fast: the subgrade heaves as it thaws and the surface breaks up. The fix is a base course built thick enough and drained, with clean stone where water collects.
Almost no fall across the lake plain means meltwater and rain sit where they land. A tight clay or peat subgrade underneath holds it there, so a drainage layer matters more than the slope of the ground.
Spring brings cutbank scour and bank slumping along the Red and its tributaries during the rise. Riprap armours those banks against ice, wave and runoff, and it also protects culvert outlets and slopes.
Wind erosion works the bare, flat, unsheltered fields. Base, drive and paver work waits for the thaw and for the clay to dry out, and spring load limits go up on North zone roads from late March into May.
The building season is short at both ends. Frost drives deep into clay that holds water and heaves hard as it thaws, and the Minnesota Residential Code footing table sets 5 feet for its Zone I counties.
