What is the best base material for a patio in St. Joseph County?

21AA limestone is the usual choice. It is a dense-graded crushed limestone with fines that compacts hard, which is what a patio base needs. Stone screenings go on top for bedding pavers or flagstone. On the sandy ground common here, compact in lifts and keep the subgrade even.

Yes. Michigan Rock Supply supplies bulk gravel, stone, sand and soil for both homeowner projects and contractor work. You order online, choose a quantity by the ton or yard, and pick a delivery date at checkout. A dump truck then delivers to the site.

Q: When is the best time of year to order base material in St. Joseph County?

Spring thaw into late fall is the working window, because frozen ground stops compaction in winter. Frost laws also limit heavy trucks on many county roads during the spring thaw. Ordering once the ground has thawed and dried gives you the best conditions for base and driveway work.

Michigan Rock Supply handles gravel, stone and aggregate delivery in St. Joseph County, MI. The base material most jobs here start with is 21AA limestone, a crushed limestone with fines that packs hard under driveways, parking pads and pole barn floors.

Ground in this county is mostly sandy: outwash plains, sandy moraines and beach sand near Lake Michigan, with clayey till and wet muck in low spots.

Ground Conditions Across St. Joseph County

Base, driveway and paver work runs from the spring thaw into late fall, and frozen ground stops compaction in winter. Frost laws limit heavy trucks on many county roads during the spring thaw, so plan a delivery date with that in mind.

Sandy soils drain fast and hold little water. Trouble comes from snowmelt and heavy rain collecting on clay till, in wet mucky ground and in low hollows, so those spots want a drainage layer under the base.

Bare sand washes out on slopes and in ditches after heavy rain and snowmelt, and Lake Michigan high water, storms and ice erode dunes and bluffs. Freeze-thaw every winter and spring softens thawing roadbeds, and gravel drives can rut there. Frost depth runs 42 inches under the Michigan Residential Code.

Choosing the Right Material

Ground next door in Cass County sits in the same sandy zone as St. Joseph County, so base and drainage choices look similar there. Projects differ more than the ground does.

Calhoun County and Branch County lie in the Southern Lower Peninsula moraines and till plains, a patchwork of loamy and clay loam till, sandy and gravelly moraines and outwash, and wet muck or peat in low spots. That means more clay and muck to work over, so drainage stone and a deeper base matter more than they do on this county's sand.

Within St. Joseph County, match the material to the job: 21AA limestone for a driveway or pad base, 22A road gravel for a hard-packing unpaved drive, pea stone for walkways and play areas, and drain rock for French drains and downspout runs, including in slow-draining clay ground.
