Bulk Aggregates for Patios in Winnebago, IL

Illinois Rock Supply handles gravel and aggregate delivery in Winnebago, IL, with CA-6 as the base material most local work starts from. That is the Illinois name for dense graded crushed limestone with the fines left in.

Winnebago sits in Winnebago County, on the till plains and Rock River country side of northern Illinois. The ground here is loamy prairie soil over dolomite, and it decides what a patio or pad needs underneath it.

Ground and Conditions in Winnebago

A thin base is the failure you see on patios and flatwork around here. Loamy prairie soil over tight till holds water, and freeze and thaw works the slab edges loose.

The fix is a base course that carries the load and a clean stone layer that moves water away. Both need to sit on ground that was stripped and shaped first.

Frost action in unbound base is real across the northern counties, where winters are among the coldest in the state. Frost depth runs about 42 inches across the northern counties, and the local building department sets it.

Spring snowmelt and rain on frozen ground push water across the surface before the soil thaws. Plan drainage so that water has somewhere to go.

The working season runs from the spring thaw into late fall. Frozen ground stops compaction in the winter, so patios and pads are built while the ground is open.

Materials for Winnebago Projects

Bedding under pavers and flatwork is where the material choice shows first. Get that layer right and the surface above it stays put.

CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in. It builds the compacted base under driveways, parking pads, shed and garage bases, and trench backfill.

Lime Screenings are crushed limestone fines. In Illinois they are the standard bedding layer under pavers and flagstone, and they backfill around pipe.

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

Where water needs to move, use clean washed stone. CA-7 is 1 inch clean stone for bedding under pipe, drainage trenches and concrete flatwork.

3/4" Crushed Stone, sold as CA-11, is the 3/4 inch clean washed stone for the same work. CA-16 Chips are 3/8 inch chips for permeable paver bedding and topping a compacted base.
