Order 21AA Limestone and Crushed Stone in Montcalm County, MI
What do you order for a rutted drive outside Greenville? For most jobs in Montcalm County, MI, the answer is 21AA limestone. Michigan Rock Supply delivers gravel, stone and aggregate delivery in Montcalm County, MI to yards and job sites across the county. The ground here is a patchwork of glacial deposits, so the right material depends on whether you are building on sand, clay loam till or muck.
21AA limestone is the dense-graded crushed limestone with fines that Michigan specifies as 21AA, and it packs into a hard, lasting base for driveways, parking pads and pole barn floors.
Delivery across Montcalm County
You order online and pick the quantity you need by the ton or the yard. Use the calculator to size the load for your driveway, pad or bed, then choose a delivery date at checkout.
A dump truck brings the material to your site and spreads the load where you point. We cover Greenville, Sidney, Howard City, Edmore, Stanton, Lakeview, Carson City, Crystal, Sheridan, Trufant, Pierson, Coral, Fenwick and Six Lakes.
Plan your order around the working season. 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 timing matters.

Give 21AA limestone the most thought. It is crushed limestone with fines, and it is what you order for a driveway, a parking pad or a shed base that has to stay put.
Ground conditions across Montcalm County
Start with the soil, because it decides how the base gets built. Montcalm County sits in the Southern Lower Peninsula moraines and till plains, a patchwork of 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.
Spring snowmelt and heavy rain drain quickly through sand and gravel. On clay till flats and in poorly drained depressions and outwash channels, water stands, and many sites rely on tile or ditches. That is where an under-built base fails first.
Rain and snowmelt also scour sloping moraine ground, roadside ditches and stream banks. RipRap and drain rock handle those spots. Freeze-thaw comes every winter and spring, and as frost leaves 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.
Choosing the right material
Compare your ground with the counties next door. Newaygo County is mostly sandy ground: sand and gravel outwash plains, sandy moraines, and beach and dune sand near Lake Michigan, with clayey till and wet muck in some low spots and hollows.
That sandy ground drains fast, so a Newaygo base needs less drainage stone than the clay till flats here. Mecosta County is mostly sandy glacial outwash plains and sandy to loamy moraines, with swamps and wet lowlands, plus thin soils over limestone and sinkholes in places in the northeast.
Kent County shares the same zone as Montcalm, loamy and clay loam till with sandy moraines, outwash and wet muck in kettle holes, so the ground is similar and the projects are similar too: driveways, pads and drainage work.
