Bulk Aggregates for Patios in Kent, IL

Planning a patio, a driveway or a drainage run around Kent means picking the right base and bedding material before anything else. Illinois Rock Supply brings gravel and aggregate delivery in Kent, IL, and CA-6 is the base most of that work starts from.

This is Driftless and old-drift northwest country, where loess sits over dolomite and limestone. Thin soil over rock changes how a base behaves, so the material you set under a patio matters more than the surface you see.

Ground and Conditions in Kent

Across the Driftless and old-drift northwest, the ground is wind-blown loess over dolomite and limestone. Soil stays thin on the ridges, and rock sits close to the surface on the steep valley sides.

A thin base over that kind of ground fails at the edges first. Water gets under the bedding layer, the pavers rock, and the joints open up.

Steep ground moves water fast into the narrow valleys, and springs and seeps come out of the dolomite. Heavy rain runs off loess ridges before it can soak in.

That runoff is why a patio or pad needs a bedding layer that handles water instead of trapping it. On a cut slope, rock fall and slumping are worth planning around too.

Work runs from the spring thaw into late fall here. A wet spring is the hard stretch, because loess on a hillside turns greasy and steep drives are slow to build.

Frost works harder on thin soils over rock and on cut slopes in this part of Illinois. Frost depth is about 42 inches across northern Illinois, and the local building department sets the figure that applies to your job.

Materials for Kent Projects

Bedding under pavers and flatwork is where the wrong pick shows up fastest. The bedding layer levels the surface and lets water move, and it has to stay put while the pavers go down.

Lime Screenings are crushed limestone fines, and they are the standard bedding layer for pavers and flagstone in Illinois. The same material backfills around pipe.

Washed Sand, which Illinois yards call torpedo sand, is coarse washed sand for concrete, leveling and bedding. Mason Sand is the finer clean sand for brick and block mortar, paver joints, sandboxes and volleyball courts.

Under the bedding, CA-6 is the Illinois base material. It is dense graded crushed limestone with the fines left in.

CA-6 goes under driveways, parking pads, shed and garage bases and trench backfill. It is a compacted base, not a drainage stone.

For water, CA-7 is washed clean stone with no fines, used for bedding under pipe, drainage trenches, French drains and concrete flatwork. 3/4" Crushed Stone, or CA-11, is the 3/4 inch clean washed stone sold alongside it for bedding, drainage and concrete work.

CA-16 Chips are 3/8 inch chips for permeable paver bedding, drainage around tanks and topping a compacted base.

Delivery to Kent 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 order.

A dump truck tips the load in one pile on site. Kent sits in Stephenson County, and delivery covers the surrounding area, including Freeport, Lena, Orangeville, Pearl City and Dakota.

For a patio, the bedding layer and the base under it are usually ordered together. Ordering both at once keeps the job moving instead of waiting on a second delivery.
