Lime Screenings for Patios in Palos Park, IL

If you are setting a patio, a walk or a set of steps, the bedding layer under it decides how the finished surface sits. Illinois Rock Supply handles gravel and aggregate delivery in Palos Park, IL, from the base course up.

You can order CA-6, also called road base, for the compacted layer below, and lime screenings for the bed the pavers sit in.

Ground here is heavy silt and clay laid down on the old Lake Chicago lake plain, and clay-rich till sits under the moraines inland. That ground sheds water instead of taking it, so the layers below your flatwork carry the load.

Ground and Conditions in Palos Park

Across the Chicago lake plain and the northeastern moraines, the subgrade is dense and slow to drain. Water sits on flat ground because there is little fall to move it along.

A thin base course over that ground shows the failure first: the surface rocks, the joints open, and low spots hold water after a summer downpour.

The fix is a base course that spreads the load and a bedding layer that stays level. Once the ground dries, it holds compaction well, which is why 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.

Frost is part of the cycle here. 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. Northeastern Illinois jurisdictions carry a frost depth of about 42 inches in the residential code, and the local building department sets the figure.

Materials for Palos Park Projects

Bedding under pavers is where these projects are won. Lime screenings, which Illinois yards also call limestone screenings, are crushed limestone fines and the standard bedding layer in the state.

They pack into a tight, level bed for pavers and flagstone, and they backfill around pipe. Order them from the Lime Screenings page.

Below the bedding, the load goes to CA-6. It is dense graded crushed limestone with the fines left in, and it takes compaction into a firm base for driveways, parking pads, shed and garage bases and trench backfill.

Yards in the Chicago area sometimes call it grade 8, grade 9 or road mix.

See CA-6 for the base course.

Where water has to move, clean washed stone does the work. CA-7, also sold as #57 stone or 1 inch clean stone, has no fines in it, so it beds pipe, feeds drainage trenches and French drains and sits under concrete flatwork.

CA-11, the 3/4 inch clean washed stone, does the same jobs at a smaller size.

Edges and joints take finer material. CA-16 chips are 3/8 inch limestone chips for permeable paver bedding and drainage around tanks.

Torpedo sand, the coarse washed sand Illinois yards sell, levels and beds, and mason sand goes into brick and block mortar and paver joints.

Questions About Gravel and Bedding in Palos Park

What gravel is best for a driveway in Palos Park?

CA-6 is the base material for a driveway here. It is dense graded crushed limestone with the fines left in, so it compacts into a firm surface over heavy clay.

It also works as the base under a paver or slab job. You can order it from the road base page.

How much material will my project need?

It depends on the area you are covering and the layer you are building. Order by the ton or by the yard, and use the calculator on the product page to size the load.

That keeps the quantity tied to your own measurements.
