Bulk Material Delivery in Willis, MI

For gravel and aggregate delivery in Willis, MI, Michigan Rock Supply stocks 21AA limestone, the standard Michigan driveway base. It is a crushed limestone with fines. Willis sits in Washtenaw County, where glacial till and sand patches sit side by side. That mix decides which material a site needs.

Water is the other half of the decision. Some ground here drains fast, and some holds water for days after a storm.

Materials for Willis Projects

Drainage drives most orders here. Spring snowmelt and heavy rain drain quickly through sand and gravel, but they stand on clay till flats and in poorly drained depressions. Washed stone and the right base keep that water moving away from a foundation, a drive or a low corner of the yard.

Start with the coarsest stone and work down to the finest. Each size has a job it does better than the others.

• RipRap: armors stream banks, culvert outlets and slopes against waves, ice and spring runoff.
• #4 Crushed Stone: heavy drainage, construction entrances and trench bottoms.
• #57 Stone: French drains, drywells and concrete aggregate.
• Drain Rock: French drains, drywells, foundation drains and downspout runs, including in slow-draining clay ground.
• 3/8" Crushed Stone: fine drainage, pipe bedding and a topping over a compacted base.

For a driveway, 21AA limestone is the base and Driveway Gravel is the surface. 22A road gravel is a different class, a hard-packing mix of stone, sand and fines for unpaved drives and private roads. It is not a drainage material.

Delivery to Willis and the Surrounding Area

You order online and choose your quantity by the ton or by the yard. If you are unsure how much a project needs, the calculator sizes the load for you. Pick your delivery date at checkout, and a dump truck brings the material to your site.

Delivery covers Willis and the rest of Washtenaw County, including Ann Arbor, Ypsilanti, Saline, Chelsea and Whitmore Lake. Place the pile where the truck can reach it and where you can move material from it. A drive, a pad or a garden bed all start with the load landing in the right spot.

Ground and Conditions in Willis

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction in winter, so timing matters as much as material choice. Frost laws also limit heavy trucks on many county roads during the spring thaw, which is worth checking before you set a date.

Freeze-thaw comes 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. On clay till flats, plan a drainage layer so meltwater has somewhere to go.

Runoff from heavy rain and snowmelt scours sloping moraine ground, roadside ditches and stream banks. RipRap and large stone hold those edges. In low spots and outwash channels, many sites rely on tile or ditches to move water.
