CA-16 Chips, Stone and Soil Delivery in Lombard, IL

Illinois Rock Supply handles gravel and aggregate delivery in Lombard, IL, and the ground here shapes what you order. Across the Chicago lake plain and the northeastern moraines, heavy silt and clay shed water instead of taking it.

That is why CA-6, the local dense graded base, goes down over a drainage layer rather than straight onto the soil.

Materials for Lombard Projects

Water is the deciding factor on most Lombard lots. Clay and dense till push storm water sideways, and flat ground gives it nowhere to fall.

A driveway or pad built without a place for that water to go will hold it instead.

Washed stone is the answer, because clean stone has no fines to turn into mud. It stays open, so water passes through and away.

Match the size to the job.

CA-7 and CA-11 are the two clean sizes Illinois contractors specify most often by number, and both work well where water has to move. CA-16 chips are the finer option, small enough to bed permeable pavers and to top a compacted base.

For the base course itself, CA-6 is the Illinois name for dense graded crushed limestone with the fines left in.

The fines let it tighten up under a drive or a shed pad, which clean stone will not do.

Where a surface needs to stay walkable, Walkway Gravel gives paths and garden walks a finer finish. For beds and borders, River Gravel is the rounded decorative option.

Lime screenings are the crushed limestone fines used to bed pavers and flagstone, and they are the standard bedding layer in Illinois. Torpedo sand, the coarse washed sand Illinois yards sell, covers concrete and leveling work.

A dump truck tips the load on site in one pile. Plan where that pile should sit, because the material stays where it lands.

Ground and Conditions in Lombard

Timing matters as much as material here. 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 until it drains.

Northeastern Illinois carries a frost depth of about 42 inches in the residential code, and the local building department sets the figure. Many freeze and thaw cycles lift drives, walks and slabs every spring.

Gravel surfaces stay soft until the ground drains.

That is the case for a clean drainage layer under a CA-6 base. Water that reaches open stone keeps moving instead of sitting against clay.
