Bulk Aggregates for Patios in Cotton, MN

If you are planning a patio, a paver walkway or a slab, you need gravel and aggregate delivery in Cotton, MN that starts with the bedding under the flatwork. Minnesota Rock Supply sells Class 5, crushed stone, sand and soil in bulk and delivers them across St.

Louis County.

This part of the state sits on thin, stony till over Precambrian bedrock, so rock is often at or close to the surface. That changes what the base under a patio has to do.

Ground and Conditions in Cotton

Across the Iron Range, North Shore and the Superior Upland, soil is thin and stony and bedrock sits close. Water cannot soak into rock, so it runs off fast and gathers in the hollows and peat basins.

A shallow base over that ground shows its failure mode quickly. The surface shifts, joints open and the edges break down after a winter of freeze and thaw.

The fix is a base that is thick enough and open enough to move water away from the bedding. On this ground the drainage layer matters as much as the base itself.

The working season is short. Frozen ground stops compaction from late autumn into April, and spring load limits run into mid-May on North zone roads.

Plan the base work for the window when the ground will take a load.

Winters are long and severe, and shallow soil over ledge lifts slabs, posts and gravel drives every spring. Frost depth is five feet in the Zone I counties the Minnesota Residential Code footing table covers, and that is a footing depth set by the building official, not a target for a gravel base.

Materials for Cotton Projects

Bedding is where a patio is won or lost. The material directly under the pavers has to compact tight, hold a level plane and stay put when the ground moves.

Granite Fines are the bedding material for pavers, flagstone and patio work, and for compacted garden paths. Minnesota granite fines come from the Crushed Stone quarried in the St.

Cloud belt, and they lock up hard under a plate.

Washed Sand, also sold as concrete sand, beds and levels under slabs and pavers. Mason Sand goes into brick and block work, paver joints, sandboxes and play areas.

Under the bedding you still need a compacted structural base, and that is Class 5. It is the standard Minnesota base course.

It goes under driveways, parking pads, shed and garage bases and road base.

Crusher Run is crushed rock with the fines left in, for base and drives that need to bind and compact. Minnesota yards more often sell it by class or by a minus size than by the name crusher run.

Where water has to move, use clean stone instead. Drainage Rock is usually a 1 1/2 inch clear rock here, for French drains, drywells, footing and foundation drains and downspout runs.
