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

If you are bedding a paver patio, setting a shed pad or topping a drive, gravel and aggregate delivery in Strathcona, MN starts with the right base material. Minnesota Rock Supply sells bulk Class 5, crushed stone, sand and black dirt by the ton or the yard.

Strathcona sits in Roseau County, on the flat lake plain of the Red River Valley. That ground drains slowly, so what you put under a patio matters as much as the pavers themselves.

Materials for Strathcona Projects

Bedding under pavers and flatwork is the job that decides whether a patio stays flat. The bedding layer has to hold a level plane and let water move, and the base under it has to carry the weight without pumping when the clay below stays wet.

Granite Fines, also called screenings or stone screenings, are the standard bedding for pavers, flagstone and patio work. They compact to a tight, level surface that locks the units in place.

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

Below the bedding, Class 5 is the Minnesota base course. It is a compacted base for driveways, parking pads, shed and garage bases and road base.

Where a tighter 3/4 inch crushed aggregate with fines is wanted. Yards sell it as Class 2 granite, buff limestone or red limestone.

For a patio edge, a walkway or a garden path, Walkway Gravel gives a finer, walkable surface that compacts underfoot. Washed Sand, also sold as concrete sand, is used for bedding, levelling and sand under slabs and pavers.

Ground and Conditions in Strathcona

The lake plain ground here is deep silt and clay that settled out in still water, with sandy beach ridges marking the old shorelines. Lake sediment is weak, frost susceptible and a poor aggregate source, so usable sand and gravel sit in the beach ridges and river terraces.

Almost no fall across the lake plain and a tight clay subgrade underneath mean meltwater and rain sit where they land. A thin base over that clay shows the failure first: ruts, soft spots and pavers that rock as the ground moves under them.

The fix is a base that carries load and a bedding layer that stays level. Class 5 builds that base.

Granite fines or washed sand set the level plane on top.

Across the Red River Valley and the northern lake plain, 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, and the building season is short at both ends.

Winters here are among the coldest in the state, with frost driven deep into clay that holds water and heaves hard as it thaws. The Minnesota Residential Code footing table sets a frost depth of 5 feet for its Zone I counties, which is a footing depth set by the building official.

Questions About Gravel and Base Material in Strathcona

What gravel is best for a driveway in Strathcona?

Class 5 is the standard Minnesota base course and the right starting point for a drive here, because it compacts into a stable layer over clay. Top it with Class 2 or driveway gravel for a tighter running surface.

Both are sold by the ton or the yard, and each product page has a calculator.
