What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone is angular, with sharp edges that lock together under compaction. That makes 21AA limestone and 3/4 inch crushed stone good bases and drainage beds. Pea stone is rounded and smooth, so it never packs tight. Use it for walkways, play areas and dog runs where you want a comfortable surface, not structural support.

Should I order material by the ton or by the yard?

Either works. Order by the ton when you know the weight you need, and by the yard when you are working from volume. If you are unsure how much a project takes, enter your measurements in the calculator and let it size the load. Then pick your delivery date at checkout.

Which stone is best for drainage in Lapeer County?

It depends on the ground. On sandy moraine, 3/4 inch crushed stone and #57 stone move water fast. On clay till flats and poorly drained depressions, drain rock in a French drain or drywell does the heavier work. Rip rap armors sloping banks and culvert outlets where runoff scours.

Lapeer County 21AA Limestone and Gravel Delivery, MI

Spring snowmelt and heavy rain drain fast through the sand and gravel moraines here. On the clay till flats, the same water stands for days. That split ground drives most material decisions in Lapeer County, and it is why 21AA limestone and open-graded drainage stone carry so much of the work.

Ground Conditions Across Lapeer County

The 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.

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction in winter, and frost laws limit heavy trucks on many county roads during the thaw.

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.

Runoff from heavy rain and snowmelt scours sloping moraine ground, roadside ditches and stream banks. On clay till flats and in poorly drained depressions, many sites rely on tile or ditches to move water.

Materials Delivered in Lapeer County

Class 21AA is the dense-graded crushed aggregate used as driveway and road base, and Class 22A is a dense-graded aggregate with a smaller top size for unpaved drives and roads.

Choosing the Right Material

Start with the base, then pick the surface. A compacted 21AA limestone base carries a drive, a parking pad or a shed. Top it with driveway gravel if you want a fresh wearing course. For a walkway or garden path, skip the heavy base and use walkway gravel or pea stone for a finer, walkable surface.

Drainage is a separate job. Use 3/4 inch crushed stone, #57 stone or drain rock in French drains, drywells and downspout runs. Rip rap armors lakefront, stream bank and culvert outlet slopes against waves, ice and spring runoff.

Neighbouring counties show how the choice shifts. Tuscola County spans more than one zone, with Southeast lake plain, Saginaw Bay and the Thumb ground alongside Southern Lower Peninsula moraines and till plains, so parts of it match Lapeer County and parts need heavier drainage. Sanilac County and St. Clair County sit on flat former glacial lake bed of clay, silty clay and clay loam, crossed by sandy beach ridges and sand channels, and most of that ground is poorly drained. There, drainage stone and tile matter more than they do on Lapeer County moraine.
