Large River Rock, Stone and Soil Delivery in Crookston, MN

Minnesota Rock Supply brings gravel and aggregate delivery in Crookston, MN to your site by the ton. Class 5 is the base course most of this work starts from, and it goes down under drives, parking pads and shed floors.

This is flat lake plain country, so the ground under your project holds water longer than you might expect. Choosing the right stone starts with what the ground does.

Materials for Crookston Projects

Spring rise moves a lot of water along the banks and ditches here, so coarse stone for slope, swale and bank protection carries a lot of the work. The bigger sizes hold where water runs hard.

RipRap is the heavy option for shorelines, culvert outlets and steep banks.

Large River Rock suits dry creek beds and lighter bank work where you want round stone rather than angular. It also works as a heavier decorative border.

Drainage Rock is usually a 1 1/2 inch clear rock in Minnesota, and it handles French drains, drywells and downspout runs. Clear means the fines were washed out, so water moves through it.

Below those sizes, Class 5 is the Minnesota base course for drives, pads and road base. It keeps its fines and compacts into a firm surface.

Ground and Conditions in Crookston

Work here waits on the season. Across the Red River Valley and the northern lake plain, base, drive and paver work waits for the thaw and for the clay to dry out.

Spring load limits go up on North zone roads from late March into May, and the building season is short at both ends. Plan your delivery around that window.

The soil is the bed of glacial Lake Agassiz: deep silt and clay that settled in still water. Lake sediment is weak, frost susceptible and a poor aggregate source, so usable sand and gravel sit on the beach ridges and river terraces.

There is almost no fall across the lake plain, and the tight clay subgrade underneath means meltwater and rain sit where they land. Drainage stone matters here because water has nowhere to go on its own.

Winter is cold enough that frost drives deep into clay that holds water and heaves hard as it thaws. The Minnesota Residential Code footing table sets a five foot frost depth for its Zone I counties, and that figure belongs to the zone, not to this city.
