When is the best time of year to order base material in Washtenaw County?

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction in winter, so a winter base will not pack properly. Frost laws also limit heavy trucks on many county roads during the spring thaw. Aim for late spring through fall, and plan around the thaw window.

What is the difference between topsoil and fill dirt?

Fill dirt is bulk fill for grading and raising low ground before a 21AA base goes down. Topsoil is screened and used for lawn and bed prep over sandy or clay glacial soils. Use fill dirt to build grade, then cap it with topsoil where you want grass or planting to take.

Gravel, Soil and Stone for Washtenaw County, MI

Michigan Rock Supply handles gravel, stone and aggregate delivery in Washtenaw County, MI. The material most local buyers ask for first is 21AA limestone, the crushed limestone with fines that builders here use as driveway and road base. From there you can add washed stone, sand, topsoil or decorative rock to the same order.

Washtenaw County ground is a patchwork of glacial deposits. You get loamy and clay loam till on flat to rolling plains, sandy and gravelly moraines and outwash, and wet muck or peat in kettle holes and other low spots. That mix decides which material works on your site.

Materials Delivered in Washtenaw County

Start with 21AA limestone. It is a crushed limestone with fines, and it packs hard once it is watered and rolled. Order it for driveways, parking pads, and pole barn or shed bases.

Class 22A is a different class. It is a dense-graded aggregate with a smaller top size, sold as 22A road gravel for unpaved drives, private roads and base work. It is not a drainage material. Around it, these are the supporting materials buyers pair with a base:

For walkways and garden paths, Walkway Gravel gives a finer, walkable surface. For paver, flagstone and patio bedding, Stone Screenings lock the pavers in place. Pea stone covers walkways, play areas and dog runs, and Mason Sand handles brick and block work plus paver joints.

Choosing the Right Material

The right material shifts with the ground under it. Wayne County and Monroe County sit on the southeast lake plain, a flat former glacial lake bed of clay, silty clay and clay loam, with most of the ground poorly drained. There, drainage stone and a raised base matter more than they do on Washtenaw's moraine ground.

Jackson County shares Washtenaw's ground zone, the Southern Lower Peninsula moraines and till plains. The deposits are similar, so the material choice is similar too. The projects differ more than the ground does: Washtenaw work leans toward Ann Arbor and Ypsilanti driveways and paver patios, while Jackson jobs tend to be rural drives and field entrances.

Match the material to the job:

New driveway or parking pad: 21AA limestone as the base, then driveway gravel on top.
Unpaved private road: 22A road gravel, which packs hard under tires.
Wet or clay ground: drain rock in the trench, with clean stone around it.
Slope or stream bank: rip rap, sized to the water it faces.
Paver patio or walkway: stone screenings for bedding, mason sand for joints.

Ground Conditions Across Washtenaw County

A thin base shows itself fast here. Spring snowmelt and heavy rain drain quickly through sand and gravel, but they stand on clay till flats and in poorly drained depressions and outwash channels. Many sites rely on tile or ditches to move that water. When the water sits, a shallow base rutting under a truck is the usual result.

The fix is a thicker compacted base plus a drainage path. On clay till flats, dig out the soft spot, run drain rock where the water collects, and build the base up in lifts you can compact. On sandy moraine ground the same base holds up with less stone because water leaves on its own.

Freeze-thaw hits every winter and spring. As frost comes out of the ground the soaked soil loses strength, so gravel drives and thin bases can rut and heave. Frost depth is 42 inches under the Michigan Residential Code, which is a footing depth set by the building official, not a base depth. Base, driveway and paver work runs from the spring thaw into late fall, and frozen ground stops compaction in winter. Frost laws also limit heavy trucks on many county roads during the spring thaw, so plan deliveries around that window.
