Bulk Aggregates for Patios in Chesterfield, IL

If you are planning a patio, a driveway rebuild, or a drainage run, gravel and aggregate delivery in Chesterfield, IL starts with the right base material. Illinois Rock Supply sells CA-6, also called road base, along with the clean stone and sand that go with it.

This is claypan country. Water sits on top of tight subsoil instead of draining away, so what you put under a patio matters as much as the pavers themselves.

Ground and Conditions in Chesterfield

Across the Southern till plain and claypan country, the subsoil sits close to the surface and stops water from moving down. Rain perches on top of it and ground stays saturated for weeks.

That is where a thin base fails first. Unbound stone under a patio or drive pumps under traffic when the ground below stays wet, and the surface starts to move.

The fix is a base that carries load and a clean drainage layer that lets water out sideways instead of trapping it. Chesterfield sits in Macoupin County, where late summer and fall are the reliable windows for this kind of work.

A wet winter and spring keep sites soft well into April. Shorter winters than upstate still bring frequent freeze and thaw swings that work on saturated clay.

Materials for Chesterfield Projects

Bedding under pavers and flatwork is where the material choice shows. CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in.

It goes down as the compacted base under a patio, a parking pad, a shed or garage slab, and a driveway. The fines bind together so the layer holds its shape.

Above the base, bedding layers and drainage runs take clean washed stone. Lime screenings, the standard bedding layer in Illinois, are crushed limestone fines for paver and flagstone bedding and for backfill around pipe.

CA-7 is washed clean stone with no fines, sized for bedding under pipe, drainage trenches, French drains and concrete flatwork. Illinois yards also sell CA-11, the 3/4 inch clean stone, for the same bedding and drainage work.

For the finest bedding, 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 concrete work.
