Bulk Material Delivery in Harwood Heights, IL

Illinois Rock Supply handles gravel and aggregate delivery in Harwood Heights, IL. CA-6, also called road base, is the dense graded crushed limestone this market builds on.

It is the Illinois base material for driveways, parking pads, shed and garage bases and trench backfill. The ground here is heavy silt and clay, so what sits under a pad matters as much as the pad.

Materials for Harwood Heights Projects

Coarse stone does the heavy work on slope, swale and bank protection around Harwood Heights. It is sized to stay put and let water move past it instead of over the top.

Ground and Conditions in Harwood Heights

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.

Across the Chicago lake plain and the northeastern moraines, the ground is heavy silt and clay over clay-rich till. It sheds water rather than takes it, and flat ground has little fall.

Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas. Sheet wash off bare clay lots is the other problem, which is why bare ground gets covered.

Long cold winters bring many freeze and thaw cycles, and frost lifts drives, walks and slabs every spring. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets it.

Questions About Stone and Delivery in Harwood Heights

What stone should I use for drainage in Harwood Heights?

CA-7 and CA-11 are the washed clean stone for drainage here. They have no fines, so water moves through instead of sitting.

Use CA-7 for pipe bedding and French drains, and CA-16 chips where you need a smaller size for tight bedding. RipRap handles bank and swale work at the coarse end.

What should I have ready when the truck arrives?

Clear the spot where the pile will land and make sure the truck can reach it. The driver tips the load in one pile and does not place or spread it.

Have your quantity settled before the delivery date, and keep the area free of vehicles and equipment so the truck has room to work.
