Bulk Gravel Delivery to Winfield, IL

Illinois Rock Supply handles gravel and aggregate delivery in Winfield, IL for two kinds of buyers: contractors working a schedule and homeowners finishing one project. Both need the right material named the way this market names it, and CA-6 is where most of that starts.

The clay-heavy ground across the Chicago lake plain shapes what holds up here.

Ground and Conditions in Winfield

Winfield sits in DuPage County on the Chicago lake plain and the northeastern moraines. The ground here runs to heavy silt and clay, and clay-rich till sits under a lot of it.

That soil sheds water rather than taking it in.

Flat ground with little fall makes that worse. A heavy summer downpour has nowhere to go, so it sits on the grade or runs across it.

Under a paver patio or a driveway, that water finds the weakest layer first.

A thin base fails first at the edges, where water reaches it from both sides. The fix is a base built from material that holds its shape when it gets wet, placed over ground that has been shaped to move water away.

If you are laying pavers or flatwork, the bedding layer and the base below it decide how the surface looks after a few winters.

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.

Schedule the heavy work around that window.

Materials for Winfield Projects

The bedding layer under pavers and flatwork is where the surface is won or lost. It has to be fine enough to level a paver and stable enough to stay put once the joints are swept.

Illinois yards sell two materials for that job, and they are not interchangeable.

Lime Screenings are crushed limestone fines, and they are the standard bedding layer in Illinois for pavers and flagstone. They compact to a firm, level plane and hold a paver without letting it rock.

The same material works as backfill around pipe.

CA-16 Chips are 3/8 inch washed chips. Use them for permeable paver bedding, for drainage around tanks, and for topping a compacted base where you want water to pass rather than sit.

Below the bedding, the base course is CA-6, also called CA6 or 3/4 dense grade. It is dense graded crushed limestone with the fines left in, and it is the Illinois base material for driveways, parking pads, shed and garage bases and trench backfill.

Chicago area yards also call this grade 8 or road mix.

Where you need clean stone instead of a compacted base, the numbers change. CA-7 and 3/4" Crushed Stone (CA-11) are washed stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.

Two more materials round out a Winfield order. Washed Sand, which this market calls torpedo sand, is the coarse washed sand for concrete, leveling and bedding.

Mason Sand is finer, for brick and block mortar, paver joints, sandboxes and volleyball courts.

Questions About Gravel in Winfield

What gravel is best for a driveway in Winfield?

CA-6 is the base material for a driveway here: dense graded crushed limestone with the fines left in, and it compacts to a firm surface. Where a drive needs drainage rather than a compacted base, CA-7 or CA-11 washed clean stone is the better choice.

On clay ground, the base below matters as much as the surface stone.

How much material will my project need?

Quantities are ordered by the ton or by the yard. Each product page has a calculator, and it works from your project measurements to give you a figure to order from.
