3/8 Inch Crushed Stone for Patios in Chisholm, MN

If you are bedding a patio, a walkway or a paver pad in Chisholm, MN, Minnesota Rock Supply delivers gravel and aggregate delivery by the ton. A paver job starts with the layer under it, and that layer is usually granite fines over a compacted Class 5 base.

Class 5 is the Minnesota name for the base course. Thin, stony ground is common across this part of the state, so the base under flatwork has to carry the load.

Ground and Conditions in Chisholm

Across the Iron Range, North Shore and the Superior Upland, soil is thin and stony till over Precambrian bedrock, with rock at or close to the surface. Water cannot soak into rock, so it runs off fast and gathers in the hollows.

That combination is hard on a patio. A shallow base over uneven ground moves, and the pavers above it follow.

The failure shows up as rocking edges and joints that open.

The fix is a properly compacted Class 5 base that spreads the load and holds its shape through the seasons. Granite fines go on top as the bedding layer that lets you set and level the pavers.

This is the shortest working season in the state. Frozen ground stops compaction from late autumn into April, and spring load limits run into mid-May on North zone roads, so plan the base work around the thaw.

Winters here are long and severe. Frost reaches rock in places, and shallow soil over ledge lifts slabs, posts and gravel drives every spring.

Materials for Chisholm Projects

Bedding is where a paver job is won. Granite fines, also sold as screenings or stone screenings, are the Crushed Stone bedding that goes under pavers, flagstone and patio slabs.

They compact to a firm, level surface you can set stone on.

Under that bedding, Class 5 is the base course for patios, driveways, parking pads and shed bases. It is the standard Minnesota base.

Where you want a tighter crushed surface with fines still in it, Class 2 is the Minnesota surfacing class. Yards sell it as Class 2 granite, buff limestone or red limestone.

For drainage under and around flatwork, 3/4 inch clear rock is washed stone with the fines taken out. It drains where a fines-bearing base would hold water.

For a finer finish over a compacted base, 3/8 inch crushed stone works as a thin topping and for tight bedding. It is sold as granite chips or as a red or buff limestone chip.

Sand bedding is its own choice. Washed sand, also called concrete sand, beds and levels under slabs and pavers.
