CA-6, Sand and Gravel Delivery in McHenry County, IL

CA-6, Sand and Gravel Delivery in McHenry County, IL

Illinois Rock Supply delivers gravel, stone and aggregate delivery in McHenry County, IL. The base material here is CA-6, also called road base: dense graded crushed limestone with the fines left in.

It goes under driveways, parking pads, shed and garage bases and trench backfill.

McHenry County sits on the Chicago lake plain and the northeastern moraines, where heavy silt and clay shed water rather than take it. That shapes what you put on the ground and how much of it.

Ground Conditions Across McHenry County

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay over clay-rich till. Water runs off rather than soaks in, and flat ground gives it little fall to work with.

That matters twice over. A fines-bearing base like CA-6 sheds part of what lands on it, and the clay beneath holds the rest until it drains.

Clean washed stone is what carries water away.

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction through the winter, and a wet spring keeps crews off soft clay.

Winters here bring many freeze and thaw cycles. Frost lifts drives, walks and slabs every spring and leaves gravel surfaces soft until the ground drains.

Frost depth in northeastern Illinois is about 42 inches, the figure local jurisdictions carry in the residential code, and the local building department sets it.

Materials Delivered in McHenry County

Article 1004.01 of the Standard Specifications for Road and Bridge Construction sets the coarse aggregate gradations CA 1 through CA 20, and CA-6 is the dense graded base among them.

CA-16 Chips are 3/8 inch limestone chips for permeable paver bedding and drainage around tanks. Mason Sand is the fine clean sand for brick and block mortar, paver joints and sandboxes.

3/8" Natural Pea Gravel and River Gravel cover walkways, play areas, beds and borders. Large River Rock handles dry creek beds and downspout splash areas.

Fill Dirt raises grade before a CA-6 base course goes down. Garden Soil fills raised beds and planting areas, and Shredded Mulch holds moisture in beds and tree rings.

Choosing the Right Material

Cook County shares the ground region with McHenry County: the Chicago lake plain and the northeastern moraines. Clay-rich till, heavy silt and clay, and little fall on flat ground.

The base and drainage choices are the same on both sides of the line.

DeKalb County and Boone County sit in Northern Illinois till plains and Rock River country. Their ground is Wisconsin Episode till and loamy prairie soils over dolomite, which is a different mix from the clay-heavy moraines here.

Lighter, loamier ground takes water differently, so a drainage layer still earns its place. A clean washed stone such as CA-7 or CA-11 does that work, while CA-6 stays the compacted base.

Frequently Asked Questions

Common questions about gravel and aggregate delivery in McHenry County

What is the best base material for a patio in McHenry County?

CA-6 is the Illinois base material for a patio. It is dense graded crushed limestone with the fines left in, which makes it a compacted base under a patio. Lime Screenings are the standard bedding layer over it in Illinois.

Can I order material for a commercial or contractor job?

Yes. You order online the same way for any size job, choosing a quantity by the ton or by the yard and picking a delivery date at checkout. Bulk loads arrive by dump truck and are tipped on site. Contractors working on drainage.

When is the best time of year to order base material in McHenry County?

Order from the spring thaw into late fall. Frozen ground stops compaction through the winter, so a base course placed then cannot be worked. A wet spring also keeps crews off soft clay until the ground drains. Plan around those two windows and the work goes more smoothly.
