Bulk Aggregates for Patios in Washington, IL

If you are planning a patio, a paver walk, or a driveway pad, gravel and aggregate delivery in Washington, IL starts with the base under it. Illinois Rock Supply sells CA-6, also called road base, along with the bedding and drainage stone that finish the job.

Washington sits on the Grand Prairie till plain of central and eastern Illinois, where the ground is flat and the subsoil is dense clay. Water stands instead of running, so what you put under a patio matters as much as the pavers on top.

Ground and Conditions in Washington

On flat ground over clay, a thin base is where patios and walks start to fail. Water gets into the subgrade and has nowhere to go, and the surface above it moves.

The fix is a base that is thick enough and a drainage layer that gives the water somewhere to travel. Across the Grand Prairie till plain of central and eastern Illinois, that combination is what keeps a flatwork job flat.

Spring is slow to dry here and winter freezes the ground solid. Base, driveway and paver work runs from the spring thaw into late fall.

Materials for Washington Projects

Bedding material is what sits directly under pavers and flatwork, and it is the layer that decides whether the surface stays level. Get the bedding right and the pavers above it stay put.

For the base course, CA-6 is the Illinois standard: dense graded crushed limestone with the fines left in, compacting into a firm pad for patios, driveways and shed bases.

Order CA-6 for the base and Fill Dirt when you need to raise grade before the base goes down.

Above the base, Lime Screenings are the standard bedding layer in Illinois, crushed limestone fines that level out under pavers and flagstone. For drainage under the same job, CA-7 is washed clean stone with no fines, used for French drains, drainage trenches and bedding under pipe.

CA-16 Chips are the small 3/8 inch chips for permeable paver bedding and for topping a compacted base. For concrete work, Washed Sand is the coarse washed sand Illinois yards call torpedo sand, used for concrete and for leveling.
