Bulk Material Delivery in Three Rivers, MI

Start with the calculator to size your load, then pick the material for gravel and aggregate delivery in Three Rivers, MI. Michigan Rock Supply delivers bulk stone, sand and topsoil by the ton. Most orders here begin with 21AA limestone, the standard Michigan driveway base, because the ground around Three Rivers is mostly sandy and drains fast.

That sandy ground is easy to work, but it moves. Sand and gravel outwash plains shed water quickly, so slopes, swales and banks need coarse stone to stay put.

Materials for Three Rivers Projects

Erosion control starts with size. The coarser the stone, the more it resists moving water, so work from the heaviest rock down to the fine material.

• RipRap is the heavy option for stream banks, culvert outlets and slope armoring against waves, ice and spring runoff.
• #4 Crushed Stone handles heavy drainage, construction entrances and trench bottoms where water moves fast.
• #57 Stone is the workhorse for drainage, French drains and concrete aggregate at a mid size.
• Drain Rock goes into French drains, drywells, foundation drains and downspout runs, including slow-draining clay ground.
• Large River Rock builds dry creek beds and covers heavier decorative and erosion work.

Below those sizes, 3/4" Crushed Stone covers drainage beds and drive surfacing, and Stone Screenings top a compacted base or bed pavers and flagstone.

For the base itself, 21AA Limestone is the dense-graded crushed limestone with fines that Michigan crews specify for driveways, parking pads and pole barn bases. 22A Road Gravel is a different class, a hard-packing mix of stone, sand and fines for unpaved drives and private roads. Neither one is a drainage stone, so keep them out of French drains.

Ground and Conditions in Three Rivers

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction in winter, so timing matters. Frost laws also limit heavy trucks on many county roads during the spring thaw, which can shape when you schedule a delivery.

Sandy soils here drain fast and hold little water. The trouble comes from snowmelt and heavy rain collecting on clay till, in wet mucky ground and in low hollows. Freeze-thaw every winter and spring softens roadbeds, so gravel drives can rut. The Michigan Residential Code sets frost depth at 42 inches, and lake-effect snow off Lake Michigan adds to the snowmelt.

Bare sand washes out on slopes and in ditches after heavy rain and snowmelt. Armor those spots with coarse stone rather than fines, and let the water run to a drain rock bed instead of sitting against a foundation.
