Bulk Aggregates for Patios in Cottage Grove, MN

If you are planning a patio, a paver walk, or a shed pad, you need gravel and aggregate delivery in Cottage Grove, MN, and you need the right base under it. Minnesota Rock Supply sells Class 5, granite fines, and the washed stone that goes with flatwork.

This part of the Twin Cities metro sits on ground that shifts between sand and heavier till, so the base you put down matters more than the surface you see.

Ground and Conditions in Cottage Grove

A thin base shows itself fast on a patio. The pavers rock, the joints open, and the edges drop after a winter of freeze and thaw.

Across the Twin Cities metro, ground varies inside a short drive. Sandy ground north of the rivers takes water fast, while till in the southern and western suburbs drains slowly.

That difference decides how much drainage stone a patio or walk needs underneath it. On slow-draining ground, water sits in the base and works on it all winter.

Bluff and ravine erosion above the Mississippi, Minnesota, and St. Croix rivers is a real driver here, along with gully cutting on graded lots and streambank scour in urban creeks after heavy rain.

Cottage Grove sits in Washington County, where that pattern shows up on slopes and new grades.

This is the longest working season in the state, running from the spring thaw into late autumn. Spring load limits go up on Metro zone roads in early March and come off in mid-April, which shapes when a load can move.

Cold winters bring repeated freeze and thaw, and drives, walks, and slabs heave where a clay loam subgrade holds water under a thin base. Frost depth runs 3 feet 6 inches in the Zone II counties the Minnesota Residential Code footing table covers, and that figure belongs to the code, not to any one town.

Materials for Cottage Grove Projects

Bedding under pavers and flatwork is the material that decides whether a patio stays flat. Granite fines, also called screenings or stone screenings, are the bedding layer for pavers, flagstone, and patio work.

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

They compact tight and hold a paver at a consistent height. Order Granite Fines for bedding and for compacted garden paths.

Class 5, also called Class 5 gravel or Cl 5, is the standard Minnesota base course. It goes under driveways, parking pads, shed and garage bases, and road base, and it is what you build a patio base on before the bedding layer.

Order Class 5 for the structural layer.

It works for drive surfacing and paver base where a tighter crushed rock is wanted.

Order Driveway Gravel for that surfacing layer.

3/4 inch clear rock, also called 3/4 inch washed rock or clear rock, is washed with the fines taken out. It handles drainage beds, drive surfacing, construction entrances, and trench backfill.

It also acts as foundation rock, or radon rock, under basement slabs and around footing drains. Order 3/4 Clear Rock for those jobs.

Drain rock, usually a 1 1/2 inch clear rock here, goes into French drains, drywells, footing and foundation drains, downspout runs, and sewer bedding. Order Drainage Rock when water needs somewhere to go.

For finishing, black dirt is what Minnesota calls topsoil, and it is usually bought screened or pulverized for lawns, sod beds, and planting beds. Order Top Soil to finish around a new patio or walk.
