Crushed Stone, Sand and Gravel in Dakota, IL

If you are planning a driveway, a patio base or a drainage run in Dakota, IL, Illinois Rock Supply delivers the gravel and aggregate delivery in Dakota, IL that the job calls for.

CA-6, also called road base, is the dense graded crushed limestone with the fines left in that most base work here starts from.

This part of Stephenson County sits in the Driftless and old-drift northwest, where deep wind-blown loess covers dolomite and limestone. That ground shapes what you put on top of it.

Materials for Dakota Projects

Grading and bed prep come first on most lots around here, and that work starts with soil, not stone. Screened topsoil is the dark, silty prairie material you spread for lawns and finish grade.

Garden soil is blended for raised beds and vegetable plots, where the native ground is too thin on the ridges to dig into. Fill dirt raises grade under a pad or a drive before a base course goes down.

Once grade is set, CA-6 by its local name is the base for driveways, parking pads and shed floors. It compacts because the fines are still in it.

Washed stone is the other half of the work. CA-7 is 1 inch clean stone with no fines, and it beds pipe and backfills drainage trenches.

3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed size for concrete flatwork and French drains.

Sand and decorative stone round out a load. Torpedo sand is the coarse washed sand for concrete and leveling, and mason sand is the finer grade for mortar and paver joints.

Natural Pea Gravel and river gravel handle walkways, beds and dry creek beds.

Ground and Conditions in Dakota

Water is what drives most of the decisions on ground like this. Steep ground moves rain and snowmelt fast into narrow valleys, and heavy rain runs off the loess ridges before it can soak in.

That runoff is why gully and rill erosion show up on steep slopes, and why cut banks slump. A clean washed stone like CA-7 or CA-11 lets water through where a fines-bearing material would hold it.

Springs and seeps come out of the dolomite, so a foundation drain or downspout run has to move water away from the structure, not into the yard. Riprap armors a culvert outlet or a pond edge where flow is concentrated.

Timing matters too. Work runs from the spring thaw into late fall, and a wet spring turns loess on a steep drive greasy and hard to build on.

Cold winters bring sharp freeze and thaw that works harder on thin soils over rock.

What stone should I use for drainage in Dakota?

Use clean washed stone, not a fines-bearing material. CA-7 and CA-11 are the 3/4 inch to 1 inch washed sizes for French drains, foundation drains and pipe bedding.

CA-16 chips work for tighter bedding and drainage around tanks. For heavy flow, riprap armors culvert outlets, pond edges and steep banks.
