3/8 Inch Crushed Stone and Bulk Aggregates for Dexter, MI

For gravel and aggregate delivery in Dexter, MI, the ground under your project decides the material. Around here that ground is a patchwork of glacial deposits: loamy and clay loam till on the flats, sand and gravel on the moraines, and wet muck in the low spots. Michigan Rock Supply starts most driveways and pads with 21AA limestone, then builds up from there.

Where water sits, the plan changes. Get the drainage layer right and the base above it stays firm through the spring thaw.

Materials for Dexter Projects

Water is the deciding factor on most jobs in and around Dexter. Clay till flats and low depressions hold water after heavy rain, so a driveway or pad built without a drainage layer ruts and heaves as frost leaves the ground. Washed stone is the fix. The washed sizes carry no fines, so water moves through the void spaces instead of pooling.

For a French drain or a downspout run, Drain Rock is the standard choice. It is coarse enough to stay open in slow-draining clay ground, and it works in drywells and foundation drains too. Where you want a smaller washed stone for pipe bedding or a tighter bed, 3/8" Crushed Stone goes in easily and drains well.

For larger volume drainage, #57 Stone handles French drains and concrete aggregate. #4 Crushed Stone suits heavy drainage, trench bottoms and construction entrances. RipRap armors culvert outlets, stream banks and slopes against runoff and ice.

Once drainage is settled, base and surface materials go on top. The table below runs coarsest to finest.

Ground and Conditions in Dexter

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction in winter, so a compacted base placed in January will not lock up the way you need it to. Spring is the harder problem. Freeze-thaw comes every winter and spring, and as frost leaves the ground the soaked soil loses strength. Gravel drives and thin bases can rut and heave.

Frost depth here runs 42 inches under the Michigan Residential Code, which is why a shallow base over clay till fails. Build deeper on the wet flats and shallower on the sandy moraines, where water drains fast. Frost laws also limit heavy trucks on many county roads during the spring thaw, so time a delivery around that window.
