Gravel, Stone and Soil for Winnebago County, IL
Illinois Rock Supply handles gravel, stone and aggregate delivery in Winnebago County, IL. The base material here is CA-6, also called CA6 or road base.
It is dense graded crushed limestone with the fines left in.
CA-6 goes down under driveways, parking pads, shed and garage bases, and trench backfill. Winnebago County sits in the Rock River hill country, where the ground runs rocky and the working season is shorter than downstate.
Ground Conditions Across Winnebago County
The working season runs from the spring thaw into late fall. Frozen ground stops compaction in the winter, so timing a delivery matters.
Across the Northern Illinois till plains and Rock River country, the ground is a mix. Tight till and a high water table sit on the flat ground.
Sand plains nearby drain almost too fast. Snowmelt and spring rain on frozen ground push water across the surface.
Erosion shows up as gully and sheet wash on the steeper slopes, with bank scour on the rivers and wind erosion on bare sand. Riprap armors those banks and culvert outlets.
A clean stone drainage layer moves water away from a base that would otherwise hold it.
Materials Delivered in Winnebago County
Article 1004.01 sets the coarse aggregate gradations CA 1 through CA 20.
Article 1005.01 sets the riprap gradations RR 3 through RR 7. That is how CA-6, CA-7 and the rest are ordered in this state.
CA-6 carries the most weight in a base build. Other materials fill specific roles, from lime screenings for paver bedding to fill dirt for raising grade before a base course goes down.
Choosing the Right Material
Stephenson County sits in the Driftless and old-drift northwest, the only corner of Illinois the Wisconsin Episode ice never covered. Its ground is deep wind-blown loess over dolomite and limestone, with thin soil on the ridges and steep valley sides where rock sits close to the surface.
That is a different ground from Winnebago County, which is Wisconsin Episode till and loamy prairie soils over dolomite. On thin loess over shallow rock, a base holds differently than it does on till.
Riprap and drainage stone carry more of the load on those steep valley sides.
DeKalb County and Boone County share Winnebago County's ground region, the Northern Illinois till plains and Rock River country. The ground is the same, so the material choice works the same way.
