This is the flat bed of glacial Lake Agassiz, where deep silt and clay settled out in still water. Plan your base around that ground, not against it.

Ground and Conditions in Moorhead

The ground here is lake sediment: weak, frost susceptible and a poor aggregate source on its own. A thin base over that clay shows its failure fast.

It pumps, shifts and ruts the first spring the thaw sets in.

Water has almost no fall to run off across this plain, and the subgrade underneath holds what lands on it. Meltwater and rain sit where they fall.

Under a paver patio or a flatwork slab, that trapped water is what moves the surface.

The fix is a base course that compacts and binds, placed over ground that drains. Class 5 is the standard Minnesota base course.

It goes down as the structural layer under drives, pads and patios.

Frost drives deep into clay that holds water, and the ground heaves hard as it thaws. Base, drive and paver work waits for the thaw and for the clay to dry out.

Spring load limits go up on North zone roads from late March into May.

Cutbank scour and bank slumping along the Red River and its tributaries during the spring rise are the regional erosion concern. Wind erosion off bare, flat, unsheltered fields is the other one.

Both argue for a bound, compacted surface rather than loose fill left open to the weather.

Materials for Moorhead Projects

Bedding is where a patio succeeds or fails on this ground. The layers under the pavers do the work, and each one has a job.

Class 5, sold as Class 5 gravel or Cl 5, is the base course under patios, driveways and parking pads. It keeps its fines, so it binds and compacts into a firm structural layer.

Granite Fines, also called screenings or stone screenings, are the paver and flagstone bedding layer. They bed the units and lock them level.

Washed Sand, also called concrete sand, is bedding and levelling under slabs and pavers. Mason Sand handles brick and block work and paver joints.

3/8" Crushed Stone, sold as granite chips or a red or buff limestone chip, gives fine drainage and a thin topping over a compacted base. 3/4 Clear Rock is washed with the fines taken out, for drainage beds and trench backfill.
