Can I order material for a commercial or contractor job?

Yes. Order online by the ton or by the yard, the same as a homeowner, and pick a delivery date at checkout that fits your schedule. A dump truck delivers the pile to your site. Size larger jobs with the calculator so the load covers the area you are building.

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

Plan around the spring thaw. Frozen ground stops compaction in winter, and frost laws limit heavy trucks on many county roads during the thaw, so the working season runs from the thaw into late fall. Ordering ahead of that window lets you place base and compact it while the ground is workable.

What is the difference between topsoil and fill dirt?

Fill dirt is bulk material for grading and raising low ground before a 21AA base goes down. Top soil is screened for growing, so it goes on lawns and beds over sandy or clay glacial soils. Use fill dirt to change the grade, then cap it with topsoil where plants will grow.

Hillsdale County, MI Aggregate and Rock Delivery

Michigan Rock Supply brings gravel, stone and aggregate delivery in Hillsdale County, MI to driveways, job sites and yards. The material most orders start with is 21AA limestone, the crushed limestone with fines that Michigan builds driveways and road base on. From there you can add washed stone, sand, topsoil and decorative rock to finish the job.

The ground here is a patchwork of glacial deposits: 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 base and drainage materials a site needs.

Materials delivered in Hillsdale County

Start with 21AA Limestone. Order it for driveways, parking pads, and pole barn or shed bases.

22A Road Gravel is a separate class with a smaller top size, a hard-packing mix of stone, sand and fines for unpaved drives and private roads. It is not a drainage material. Add washed stone where water has to move.

Round out a load with Stone Screenings for paver and patio bedding, Pea Stone for walkways and play areas, or Top Soil screened for new lawns and beds.

Ground conditions across Hillsdale County

A thin base shows up fast here. Gravel drives and thin bases rut and heave as frost comes out of the ground and the soaked soil loses strength. Frost depth runs 42 inches under the Michigan Residential Code, and freeze-thaw returns every winter and spring.

The fix is building the base deep enough and draining it. Where sand and gravel shed water quickly, clay till flats and poorly drained depressions hold it, and many sites rely on tile or ditches.

Runoff from heavy rain and snowmelt scours sloping moraine ground, roadside ditches and stream banks, which is where rip rap earns its place. 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.

Choosing the right material

Jackson County, Calhoun County and Lenawee County sit in the same ground zone as Hillsdale County: the same patchwork of till plains, sandy and gravelly moraines, and wet muck or peat in low spots. The ground is similar, so the material choices are too.

What changes is the project. A farm drive with a soft, wet run may need 22A road gravel over a drained base, while a subdivision pad on gravelly outwash may only need 21AA limestone. Lakeside and streamside work points to rip rap.

In any of those counties, match the base to how the ground drains and how heavy the traffic is, then add washed stone where water has to leave.
