Class 5 is the base most drives, pads and shed floors are built on here. This is bluff country, so where water goes matters as much as what you put down.

Materials for St. Charles Projects

Water is the thing to plan around on this ground. On steep slopes it runs off fast and then vanishes into sinkholes and fractures instead of soaking in evenly.

That makes clean washed stone the starting point for a lot of work here, because it passes water instead of holding it.

Drainage Rock, usually a 1 1/2 inch clear rock, is the standard for French drains, drywells, footing drains and downspout runs. A downspout run piped toward a sinkhole sends roof water straight to groundwater, so route it to daylight or a drywell instead.

3/4 Clear Rock is the smaller clean stone, washed with the fines taken out. Use it for drainage beds, trench backfill and construction entrances.

The same clean stone under a basement slab is what Minnesota calls foundation rock or radon rock.

RipRap armours the places where fast water arrives: culvert outlets, streambanks, slope toes and shoreline against ice and spring runoff.

For a drive or a pad, the base course is Class 5, also called Class 5 gravel or Cl 5. It is the standard Minnesota base, and it keeps its fines so it binds and compacts.

Over a compacted base, Driveway Gravel finishes the surface. Class 2 is the surfacing class in Spec 3138, a tighter 3/4 inch crushed rock sold as Class 2 granite or limestone.

Where you want a walkable surface, Walkway Gravel compacts finer underfoot. For bedding pavers, flagstone and patio work, Granite Fines, also called screenings, is the material that beds and locks them.

Around planting and foundations, Minnesota River Rock handles decorative beds, borders and dry creek beds.

Ground and Conditions in St. Charles

The working season here runs long, from the thaw into late autumn. Spring load limits go up on Southeast zone roads in early March and come off in April, which shapes when a delivery can move.

The ground itself is loess over residual soil on limestone, dolostone and sandstone. It is thin on the ridge tops and 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 disappears underground rather than soaking in evenly, so valley floors flood quickly after heavy rain.

That pattern drives rill and gully erosion on steep slopes and bluff slumping. It also means drainage material has to move water away from the structure rather than let it sit against it.

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 a frost depth of 3 feet 6 inches for its Zone II counties.

What gravel is best for a driveway in St. Charles?

Class 5 is the usual base here, because it keeps its fines and compacts into a firm course over this ground. Finish the surface with Class 2, a tighter 3/4 inch crushed rock, or with Driveway Gravel over a compacted base.

Where water needs to move, keep clean washed stone for the drainage and leave the fines-bearing material for the driving surface.
