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

Crushed stone is quarried rock broken to a size and sold by class or by inch size, so Class 5 and 3/4 inch clear rock are both crushed stone. Natural Pea Gravel, also called pea rock, is small round washed stone. Crushed stone has angular faces and binds when it compacts; Natural Pea Gravel stays loose, which suits walkways, play areas and exposed aggregate work.

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

Both work, and the choice depends on the material and how you are used to ordering. Each product page has a calculator to help you size the load before you check out. Pick the unit that matches your figures and set the quantity when you order online.

Which stone is best for drainage in Norman County?

On the flat lake plain, clean washed stone is the right choice, because water sits where it lands and needs somewhere to go. Drainage rock, usually a 1 1/2 inch clear rock, suits French drains, drywells and footing drains. For a drainage bed or trench backfill, 3/4 inch clear rock works well.

Minnesota Rock Supply handles gravel, stone and aggregate delivery in Norman County, MN. Class 5 is the base material most of that work starts from here, and it is the name to use when you order.

Norman County sits on the flat bed of glacial Lake Agassiz, where deep silt and clay settled out in still water. That ground shapes which material you want and when it can go down.

Ground Conditions Across Norman County

Across the Red River Valley and the northern lake plain, the working season starts when the ground thaws and the clay dries out. Base, drive and paver work waits on both.

Spring load limits go up on North zone roads from late March into May. Plan a delivery date around that window rather than against it.

The lake plain has almost no fall, and the subgrade underneath is tight clay or peat. Meltwater and rain sit where they land instead of running off.

That standing water is why drainage stone matters as much as base stone on this ground. A clean washed rock gives water somewhere to go.

Lake sediment is weak, frost susceptible and a poor aggregate source. Usable sand and gravel sit in the beach ridges and river terraces instead.

Frost drives deep into clay that holds water and heaves hard as it thaws. The Minnesota Residential Code footing table sets 5 feet (60 inches) for its Zone I counties, and the building official sets footing depth.

Erosion along the Red and its tributaries comes from cutbank scour and bank slumping during the spring rise. Wind moves bare, flat, unsheltered fields too.

Class 5 is the standard Minnesota base course. Minnesota aggregate is specified by class under Section 3138, and county highway departments and cities write their own standards against the same class numbers.

Class 5 gravel goes under driveways, parking pads, shed and garage bases and road base. It keeps its fines, so it binds and compacts into a firm surface.

Yards sell it as Class 2 granite, buff limestone or red limestone.

Clear rock is the Minnesota way of saying washed with the fines taken out. Foundation rock, also called radon rock, is the same clean washed stone under basement slabs and footing drains.

Black dirt carries lawns and beds, and garden soil is a mix of screened black dirt and compost for raised beds. Shredded mulch holds moisture through the dry stretch of a Minnesota summer.

Choosing the Right Material

Clay County and Mahnomen County share Norman County's ground region, the flat bed of glacial Lake Agassiz. The ground is the same, so the base and drainage choices carry over unchanged.

Becker County is different. It sits in West Central Minnesota on north central lakes, moraine and outwash country, with sandy loam over gravel around the lakes.

That outwash ground drains on its own in places where Norman County clay does not. On this side, drainage stone does work that sand and gravel do by themselves there.

On the lake plain, start with Class 5 for a compacted base and add clear rock or drainage rock where water has nowhere to go. On outwash ground, the same base still works, but the drainage layer matters less.
