Bulk Aggregates for Patios in Coulterville, IL

Planning a patio, a driveway rebuild or a drainage run starts with the right material, and Illinois Rock Supply handles gravel and aggregate delivery in Coulterville, IL. If you are setting pavers or pouring flatwork, the base under it decides how the job holds up.

CA-6, also called road base, is the dense graded crushed limestone with the fines left in that most Illinois base work is specified from. That is where a patio build starts.

Ground and Conditions in Coulterville

Across the Western Illinois loess uplands and the Mississippi border, deep loess sits over older drift on rolling ground, and it sheds water fast on slopes while holding it in the flats. A thin base shows that quickly: soft spots after a wet spring, pavers that rock, edges that drop.

Water is the reason. Where runoff concentrates, loess gullies, and in the sinkhole country it disappears into the ground instead of running to a ditch.

So the base has to carry the load and move water away from it. A compacted CA-6 course does the first job, and a clean stone layer beside or under it gives water somewhere to go.

Work runs from the spring thaw into late fall here, a little longer than upstate. Cold winters bring freeze and thaw, and frost still lifts drives and walks each spring.

Materials for Coulterville Projects

Bedding is what makes a patio or walk last. The layer directly under the pavers has to be fine, uniform and easy to screed, and in Illinois that layer is lime screenings, also called limestone screenings or stone dust.

Set the pavers on lime screenings and the surface stays true. The base below it is a different material with a different job.

CA-6 is the compacted base for drives, parking pads and the structural course under flatwork. Dense graded crushed limestone with the fines left in, it binds when it is compacted.

Clean washed stone handles water. CA-7, also called #57 stone or 1 inch clean stone, is washed clean with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.

CA-11, the 3/4 inch clean washed stone, does the same work at a smaller size. CA-16 chips are the 3/8 inch limestone chips for permeable paver bedding and drainage around tanks.

For a patio specifically, the usual pairing is CA-6 for the base, lime screenings for the bedding, and CA-7 or CA-11 behind a retaining wall or along a drain.

Sand and soil round out a patio job. Torpedo sand is the coarse washed sand Illinois yards sell for concrete and leveling, and mason sand is the finer clean sand for brick and block mortar and paver joints.

Screened topsoil covers the disturbed ground once the hard work is done, and shredded mulch handles the beds and tree rings around it.
