Materials for Wilmette Projects

Decorative rock does a lot of the finish work on Wilmette properties. It covers bare ground, edges beds and borders, and holds a dry creek bed together where water runs across a yard.

River gravel is rounded decorative gravel for beds, borders and dry creek beds. Large river rock is the bigger rounded stone for dry creek beds, downspout splash areas and heavier decorative work.

For a walkable surface, 3/8" Natural Pea Gravel is rounded washed gravel for walkways, play areas and fence post mix. Walkway Gravel gives paths and garden walks a finer surface.

Underneath all of it, CA-6 builds the base. It is dense graded crushed limestone with the fines left in, for driveways, parking pads, shed and garage bases and trench backfill.

Where water has to move, CA-7 is washed clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork. CA-11 is the 3/4 inch clean washed stone sold alongside it for bedding, drainage and concrete work.

Lime Screenings are crushed limestone fines for paver and flagstone bedding and for backfill around pipe. Torpedo sand is coarse washed sand for concrete, leveling and bedding.

Ground and Conditions in Wilmette

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

Heavy summer downpours overwhelm yard grades in the older built-up areas. Water that cannot drain sits against a base and works at it.

An under-built base shows up first on clay. CA-6 with its fines left in compacts into a tight surface, while CA-7 and CA-11 stay clean and open so water passes through instead of pooling.

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.

Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code. The local building department sets it, and frost lifts drives, walks and slabs every spring.
