Order Gravel, Stone and Soil in Winona, MN

Minnesota Rock Supply handles gravel and aggregate delivery in Winona, MN, and the ground here decides how much base a job needs. Across the Driftless bluff and karst country, loess sits over limestone, dolostone and sandstone, thin on the ridge tops and deep in the valleys.

That means an under-built pad can move. Class 5 is the Minnesota base course to start from, and it is what holds a drive or a building pad together on ground like this.

Delivery to Winona and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to size the load before you commit.

A dump truck tips the material in one pile on your site. Winona sits in Winona County, and delivery covers the city and the surrounding area, including St.

Charles, Lewiston, Rollingstone, Altura and Dakota.

Bulk loads are heavy, so it helps to have the drop point reachable by a truck before the material arrives. Everything is ordered online and a truck brings it to the site.

Materials for Winona Projects

Raising grade and building pads are the work that shapes most of what you need here. On bluff ground, fill goes down first to bring a low spot or a sloped pad up to level, then a compacted base course goes over it.

Start with Fill Dirt for bulk fill, raising grade and backfill.

Over that, Class 5 is the standard Minnesota base course. It is a compacted base for driveways, parking pads, shed and garage bases and road base.

For a driveway, Driveway Gravel surfaces an existing drive or finishes over a compacted base. Where you want a tighter 3/4 inch crushed aggregate with fines, Class 2 is the surfacing class in the same spec, sold as Class 2 granite or limestone.

For a patio or paver area, Granite Fines bed pavers, flagstone and patios and compact paths. Minnesota granite fines come from the Crushed Stone quarried in the St.

Cloud belt.

For a drain, Drainage Rock fills French drains, drywells, footing and foundation drains and downspout runs. It is usually a 1 1/2 inch clear rock here, washed with the fines taken out.

Under a basement slab, 3/4 Clear Rock is the clean washed rock, also called foundation rock or radon rock. It forms the gas-permeable layer beneath the passive radon system Minnesota requires in new homes.

Ground and Conditions in Winona

The soil here is loess over residual soil on Paleozoic limestone, dolostone and sandstone. It is thin on the ridge tops, deep in the valleys, with rock outcrops on the bluffs and little or no glacial drift.

This is karst ground, worked by groundwater into sinkholes, springs and caves. Water runs off steep slopes fast and then disappears into sinkholes and fractures rather than soaking in evenly.

Surface flow is flashy, valley floors flood quickly, and a downspout run aimed at a sinkhole goes straight to groundwater. Rill and gully erosion on steep loess slopes and bluff slumping follow heavy rain.

For a pad, that argues for getting fill and sub-base right before the base course goes down. A thin, silty soil over rock moves when water gets under it, so the fill layer carries the grade and the Class 5 carries the load.

The working season runs from the thaw into late autumn, one of the longer ones in the state. Spring load limits go up on Southeast zone roads in early March and come off in April, which affects how heavy a load can move.

Cold winters bring repeated freeze-thaw, and frost lifts slabs and walks on the thin, silty soils over rock. The Minnesota Residential Code footing table sets 3 feet 6 inches for its Zone II counties, and that figure belongs to those counties, not to Winona.
