3/8 Inch Crushed Stone for Patios in St. Michael, MN

Minnesota Rock Supply sells gravel and aggregate delivery in St. Michael, MN to two kinds of buyers: contractors setting paver patios and flatwork, and homeowners finishing a drive or a bed.

Class 5 is the base most of that work starts from here.

St. Michael sits in Wright County, on ground where loam over till meets the sand and gravel terraces along the rivers.

That mix changes how a patio base behaves, so it is worth picking material for the ground you actually have.

Ground and Conditions in St. Michael

Across the Central Minnesota moraine and granite belt, the ground is pocked with lakes, sloughs and closed basins. Till holds water, so low spots pond through the thaw while the sand and gravel terraces along the rivers drain freely.

A paver patio built thin over a wet subgrade is where trouble shows first. Deep frost and repeated freeze-thaw heave the surface, and the heaving is worst on loam and clay loam over till.

The bedding layer and the base below it have to match that ground.

Work on base, drives and pavers runs from the thaw into late autumn. Spring load limits go up on Central zone roads in March and come off in late April or early May, which sets the start of the season.

For footing depth, the Minnesota Residential Code table sets 42 inches for its Zone II counties. That is a footing figure the building official applies, not a depth to build a gravel base to.

Materials for St. Michael Projects

Bedding under pavers and flatwork is the part of the job that decides whether the surface stays flat. Class 5 is the standard Minnesota base course.

It goes under driveways, parking pads, shed and garage bases and road base. It carries fines, so it binds and compacts into a firm platform that spreads the load before the bedding layer goes on.

Above that base, Granite Fines bed pavers, flagstone and patio stone, and make a compacted garden path. Minnesota granite fines come from the Crushed Stone quarried in the St.

Cloud belt, and they are also sold as screenings or stone screenings.

For a tighter crushed surface, Driveway Gravel is the Class 2 material, a 3/4 inch minus crushed rock with fines.

Where a fine, walkable surface is wanted, Walkway Gravel suits garden paths and walkways that need to compact underfoot.

Drainage around a patio or a footing drain calls for clean stone. Drainage Rock is usually a 1 1/2 inch clear rock here, and clear rock means washed with the fines taken out.

3/4 Clear Rock covers drainage beds, trench backfill and under-slab work.

For sand bedding, Washed Sand levels under slabs and pavers and is also sold as concrete sand. Mason Sand handles brick and block work, paver joints and sandboxes.

Questions About Gravel and Stone in St. Michael

What gravel is best for a driveway in St. Michael?

Class 5 is the standard Minnesota base course and the right starting point for a drive, because it binds and compacts into a firm platform. Top it with Driveway Gravel (Class 2), a 3/4 inch crushed surfacing aggregate, or with crusher run where you want the fines left in.

On ground that ponds through the thaw, put clean stone in the wet spots first.
