Start with Class 5 for the base under a patio, a pad or a drive. Then pick the bedding that finishes the surface.

Ground and Conditions in Andover

A paver patio fails at the base before it fails at the surface. Water sits in the subgrade, the base shifts under freeze and thaw, and the stones rock and step out of line.

Across the Twin Cities metro the ground changes fast over a short drive. Sandy ground north of the rivers takes water quickly, and till through the western and northern suburbs drains slowly.

Both matter under flatwork. Water that cannot leave the base stays in it, and a thin base over a wet subgrade is what lifts and shifts each spring.

Build the base course in Class 5 and let it bind and compact. Below it, clean washed rock gives water a path out from under the slab or the pavers.

The working season here is the longest in the state, 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.

The Minnesota Residential Code footing table sets Zone II counties, which include Anoka County, at a frost depth of 3 feet 6 inches. That figure belongs to the code table, not to a gravel base you build.

Materials for Andover Projects

Bedding decides how a patio, walk or driveway looks in five years. Pick it for the job it does under the surface.

• Granite Fines: also called screenings, this is the bedding that levels pavers and flagstone and packs down hard under a patio or a garden path.
• Washed Sand: also sold as concrete sand, it beds and levels under slabs and pavers where a sand layer is wanted.
• Class 5: the standard Minnesota base course, and the compacted layer under drives, parking pads and shed or garage bases.
• Driveway Gravel: tops an existing drive or finishes over a compacted base.
• Drainage Rock: a 1 1/2 inch clear rock for French drains, drywells, footing drains and downspout runs.

It surfaces a drive or beds pavers where a tighter stone is wanted.

Under a patio or a walkway, clean washed stone keeps water moving instead of holding it. 3/4 Clear Rock is the washed choice with the fines taken out.
