3/8 Inch Crushed Stone for Patios in Hill City, MN

Minnesota Rock Supply sells gravel and aggregate delivery in Hill City, MN to two kinds of buyers: contractors setting paver patios and flatwork, and homeowners bedding a walkway or a shed pad. Both need the same thing underneath, a base that stays put.

Class 5 is the Minnesota base course, and it carries the load under patios, drives and pads here. The ground around Hill City is sandy loam over gravel in places and peat in the low spots, so the base has to bridge what sits below it.

Ground and Conditions in Hill City

Across the North central lakes, moraine and outwash country, the ground runs in two moods. Outwash sand takes water fast, while the moraine till between the lakes does not.

A thin base over that mix shows its failure at the edges. Sand shifts, the bedding washes out from under the pavers, and the surface rocks and dips within a season or two.

The fix is a base course with fines that bind and compact, built over ground that drains. Class 5 keeps its fines, so it knits into a firm layer instead of staying loose.

Snowmelt moves the most water of the year, and spring load limits go up on North and North-Central zone roads from March into May. Frozen ground stops compaction through the winter, so base and paver work runs from the spring thaw into late autumn.

Deep frost every winter is hardest where a sandy surface sits over tight till or a high water table, with nowhere for the water to go as it freezes. The Minnesota Residential Code footing table sets five feet for its Zone I counties, and the building official sets footing depth.

Materials for Hill City Projects

Bedding under pavers and flatwork is where the choice of material shows. Each layer has a job, and swapping one for another is what causes most callbacks.

Class 5 is the standard Minnesota base course. It goes down as the structural layer under driveways, parking pads, shed and garage bases and road base, and its fines let it compact into a firm platform.

Granite Fines are the bedding layer itself. Also called screenings or stone screenings, they bed pavers, flagstone and patio stone, and they compact into garden paths.

Minnesota granite fines come from the Crushed Stone quarried in the St. Cloud belt.

Washed Sand, also sold as concrete sand, is the other bedding option, for levelling and sand under slabs and pavers. Mason Sand is the finer choice for brick and block work and paver joints, and it also fills sandboxes and play areas.

Where the subgrade needs lifting before any base goes down, Fill Dirt raises grade and backfills.
