Bulk Aggregates for Patios in Warren, MN

Minnesota Rock Supply sells gravel and aggregate delivery in Warren, MN on the schedule the ground allows. Base, drive and paver work waits for the thaw and for the clay to dry out.

Order Class 5 for the heavy base work and bedding material for everything that sits flat.

Ground and Conditions in Warren

Across the Red River Valley and the northern lake plain, the ground is the flat bed of an old glacial lake. Deep silt and clay settled out in still water, and the lake clay holds water instead of passing it.

There is almost no fall across the lake plain. Meltwater and rain sit where they land over a tight clay subgrade, so a thin base under a patio or walk shows the failure fast: soft spots, rocking slabs, joints that open as the ground moves under them.

The fix is a base that starts below the reach of a hard frost and a clean layer that lets water move. This part of the state gets deep frost driven into clay that heaves hard as it thaws.

The Minnesota Residential Code footing table sets 60 inches for its Zone I counties, which is the figure the building official uses for footings, not a depth for a gravel pad.

Spring load limits go up on North zone roads from late March into May, and the building season is short at both ends. Plan flatwork for the dry stretch between them.

Materials for Warren Projects

Bedding is where a patio is won or lost here. The layer under the pavers has to compact tight and stay put, and it has to sit on a base that already drains.

Class 5 is the standard Minnesota base course. It goes down first under patios, driveways, parking pads, shed and garage bases and road base.

Order Class 5 for the structural layer.

Above it, Granite Fines bed the pavers, flagstone and patio stone. Minnesota granite fines come from the Crushed Stone quarried in the St.

Cloud belt. They also compact into garden paths.

• Driveway Gravel, sold here as Class 2 granite or Class 2 limestone, is a tighter 3/4 inch crushed aggregate with fines for drive surfacing and paver base.
• Washed Sand, also called concrete sand, beds and levels under slabs and pavers.
• 3/4 Clear Rock, or clear rock, is washed with the fines taken out, so it works for drainage beds and trench backfill.
• Fill Dirt, called common borrow, raises grade and backfills before a Class 5 course goes down.

For a lawn or a planting bed after the hard work, black dirt is what Minnesota calls topsoil. Top Soil comes screened or pulverized for sod beds and planting beds.
