Rip Rap and Bulk Aggregates for Lake Forest, IL

Illinois Rock Supply provides gravel and aggregate delivery in Lake Forest, IL. The base material here is CA-6, also called road base: dense graded crushed limestone with the fines left in.

It goes under driveways, parking pads, shed and garage bases and trench backfill. On the clay and till ground of the Chicago lake plain, water sheds rather than soaks, so what you put on top matters.

Materials for Lake Forest Projects

Slope, swale and bank protection starts with coarse stone. Water moves fast off clay, and heavy broken stone holds a bank where finer material washes out.

Rip rap is the heaviest option. It armors banks, culvert outlets, pond edges and slopes.

See RipRap.

Below that in size, CA-7 is washed clean stone with no fines. It beds pipe, fills drainage trenches and French drains, and sits under concrete flatwork.

Order it as CA-7.

CA-11 is the 3/4 inch clean washed stone that Illinois yards sell alongside CA-7 for bedding, drainage and concrete work. It is listed as 3/4" Crushed Stone.

For tighter work, CA-16 chips are 3/8 inch stone for permeable paver bedding, drainage around tanks and topping a compacted base. Find them at CA-16 Chips.

At the fine end, lime screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe. They are the standard bedding layer in Illinois.

See Lime Screenings.

Ground and Conditions in Lake Forest

Base, driveway and paver work here 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 with clay-rich till inland. It sheds water rather than taking it, and flat ground has little fall.

Heavy summer downpours overwhelm yard grades and storm sewers in the older built-up areas. That is why drainage stone and bank protection carry so much of the work on a sloped or low lot.

Long cold winters bring many freeze and thaw cycles, and frost lifts drives, walks and slabs every spring. Gravel surfaces stay soft until the ground drains.
