Pea Gravel and Bulk Aggregates for Oak Park, MN

Minnesota Rock Supply handles gravel and aggregate delivery in Oak Park, MN, from your first yard of Class 5 to a full load of washed stone. Oak Park sits on the Central Minnesota moraine and granite belt, where loam over till holds water and low spots pond through the thaw.

That ground decides how deep a base has to go. Weigh what the site actually needs, then order it by the ton.

Materials for Oak Park Projects

Till and closed basins shed water poorly, so Oak Park jobs lean on washed stone for drainage. Start with the coarsest sizes and work down.

Drainage Rock is the 1 1/2 inch clear rock that goes into French drains, drywells and footing drains. Because the fines are washed out, water moves through the voids instead of sitting in them.

Downspout runs, trench backfill and construction entrances take 3/4 Clear Rock. It drains the same way and doubles as drive surfacing when you want clean stone rather than a compacting grade.

For fine drainage, pipe bedding and a thin topping, 3/8" Crushed Stone works at the small end. This same washed granite is also sold as granite chips, and the quarries in the St.

Cloud belt are where it comes from.

Foundations need their own stone. 3/4 Clear Rock acts as the clean under-slab layer that lets gas move beneath a passive radon system, and it drains footing trenches at the same time.

Where the grade has to come up before anything else goes down, Class 5 is the Minnesota base course. It has the fines left in, so it binds and compacts under a drive, a parking pad or a shed base.

Above that base, Driveway Gravel tops an existing drive. Class 2 is the Minnesota surfacing class for a tighter 3/4 inch crushed aggregate, sold as Class 2 granite or limestone depending on the quarry.

Delivery to Oak Park and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on your site.

Each product page has a calculator if you want to size the load before you order. Delivery covers Oak Park and the rest of Benton County, including Sauk Rapids, Foley and Rice.

Think about where the pile should land before the truck arrives, since the load comes off in one spot and stays there. Access matters: the truck needs a line it can back along to reach the spot you want.

Ground and Conditions in Oak Park

Base, drive and paver work in this part of the state runs from the thaw into late autumn. In the Central zone, spring load limits go up on roads in March and come off in late April or early May.

If your delivery lands in that window, plan the timing around the weight restrictions.

The moraine ground here is loam over till, with granite at or near the surface and outwash sand and gravel along the river valleys. Till holds water, and the ground is pocked with lakes, sloughs and closed basins, so low spots pond through the thaw.

Frost drives the base-depth decision. This is deep frost country with repeated freeze-thaw, and heaving shows up worst on loam and clay loam over till and on drives built thin over a wet subgrade.

Footing depth for Zone II counties is set at 3 feet 6 inches in the Minnesota Residential Code, and the building official has the final word on it.

Erosion follows the same pattern. Tilled slopes sheet and gully after heavy summer rain, and shorelines take wear from wind and wave.

Washed stone is the practical answer to wet ground. A clean, open drainage layer moves water instead of trapping it, which matters more here than it would on well-drained sand.
