Bulk Aggregates for Patios in Cologne, MN

Planning a patio, a paver walk, or a driveway pad in Cologne? Minnesota Rock Supply handles gravel and aggregate delivery in Cologne, MN, and the material under the pavers matters as much as the pavers themselves.

Class 5 is the Minnesota base course, and it is the first thing to plan for under flatwork. From there you pick the bedding layer and the drainage stone that finish the job.

Ground and Conditions in Cologne

Cologne sits in Carver County, in the Twin Cities metro, where the ground changes over a short drive. Till in the western and southern suburbs drains slowly, and the sand and gravel terraces along the Minnesota River move water fast.

On a slow-draining subgrade, a thin base is where a patio or drive shows its first failure. The slab or the pavers rock, the joints open, and the edges drop after a winter of freeze and thaw.

The fix is a base course that compacts into a stable layer and a drainage layer that gives water somewhere to go. Class 5 brings the fines that bind and compact; clear rock is washed with the fines taken out, so it passes water instead.

This part of the state has the longest working season in Minnesota, running from the spring thaw into late autumn. Spring load limits go on Metro zone roads in early March and come off in mid-April, which is when hauling gets easier again.

Cold winters bring repeated freeze and thaw, and heaving shows up in drives, walks and slabs wherever a clay loam subgrade holds water under a thin base.

Frost depth for the Zone II counties in the Minnesota Residential Code footing table is 3 feet 6 inches, a footing figure set by the building official rather than a target for a gravel base.

Materials for Cologne Projects

Bedding under pavers and flatwork is where the finish is decided. Get the layers right and the surface stays flat; skip a layer and the pavers move.

Class 5 is the standard Minnesota base course. It goes down as the compacted base under a patio, a driveway, a parking pad, or a shed and garage slab.

Granite Fines are the bedding layer itself. Also called screenings or stone screenings, they bed pavers, flagstone and patio stone and compact into garden paths.

Washed Sand, sold as concrete sand, is the other bedding choice, used for levelling and as sand under slabs and pavers.

Driveway Gravel tops an existing drive or finishes over a compacted base. Minnesota yards sell the surfacing class as Class 2 granite, buff limestone or red limestone.

Drainage Rock handles the water. It is a 1 1/2 inch clear rock in Minnesota, used in French drains, drywells, footing drains and downspout runs.
