Crushed Stone, Sand and Gravel in Oslo, MN

Minnesota Rock Supply handles gravel and aggregate delivery in Oslo, MN, and the season sets the schedule. Base, drive and paver work waits for the thaw and for the clay to dry out.

Class 5 is the base most of that work starts from here. It goes down as a compacted course under drives, parking pads and shed slabs.

Materials for Oslo Projects

Class 5 is the standard Minnesota base course. It carries driveways, parking pads, garage and shed bases, and road base across Marshall County.

Class 2 is the surfacing class in the same spec, a 3/4 inch crushed aggregate with fines. Yards sell it as Class 2 granite, buff limestone or red limestone.

Driveway gravel tops an existing drive or finishes over a compacted base. Crusher run, sold by class or by a minus size, binds and compacts where a base needs to hold together.

Clear rock is washed with the fines taken out, which is what separates it from Class 5. It works in drainage beds, trench backfill and construction entrances.

Granite fines bed pavers, flagstone and patio stone and compact garden paths. The Crushed Stone comes from the St.

Cloud belt.

For planting, black dirt is what Minnesota calls topsoil, and it is usually bought screened or pulverized. Garden soil fills raised beds, and shredded mulch holds moisture in beds and tree rings.

Ground and Conditions in Oslo

Across the Red River Valley and the northern lake plain, water sits where it lands. The ground is nearly flat and the subgrade underneath is tight clay or peat.

That matters before anything is ordered. A base course over ground that holds water will not stay put through a thaw.

The soil here is the bed of glacial Lake Agassiz, deep silt and clay that settled out in still water. Lake sediment is weak, frost susceptible and a poor aggregate source.

Usable sand and gravel sit in the beach ridges and river terraces instead. That is where the material for this part of the state is dug.

Spring is the hard stretch. Meltwater and rain sit on the flat ground, and spring load limits go up on North zone roads from late March into May.

Frost drives deep into clay that holds water and heaves hard as it thaws. The building season is short at both ends, so timing a delivery matters as much as the material itself.
