Start with CA-6, the dense graded crushed limestone this market calls road base. It carries the fines, so it packs into a firm surface for drives, parking pads and shed bases.

Materials for Coal Valley Projects

Water is the reason most of this page is washed stone. Across the Western Illinois loess uplands and the Mississippi border, loess sheds water fast on slopes and holds it in the flats, so footing drains, downspout runs and drywells have to move it away from the structure.

Washed stone is the material for that work. It has no fines, so water runs through it instead of sitting in it.

Coarse washed stone

RipRap is the heaviest size, broken stone for bank protection, culvert outlets, pond edges and slope armoring.

#4 Crushed Stone is the largest clean size, for construction entrances, heavy drainage and trench bottoms.

Bedding and drainage stone

CA-7, sold here as CA-7, is washed clean stone with no fines. Use it for bedding under pipe, drainage trenches, French drains and concrete flatwork.

3/4" Crushed Stone is the CA-11 size, the 3/4 inch clean washed stone yards sell alongside CA-7 for bedding, drainage and concrete work. #67 Stone is the same 3/4 inch washed size by number.

CA-16 Chips are 3/8 inch chips for permeable paver bedding, drainage around tanks and topping a compacted base. Drain Rock covers French drains, drywells, foundation drains and downspout runs.

Base, sand and soil

For the base course, CA-6 is the Illinois material: dense graded crushed limestone with the fines left in. Driveway Gravel surfaces an existing drive or tops a compacted base.

Washed Sand is torpedo sand, the coarse washed sand for concrete, leveling and bedding. Mason Sand is the finer clean sand for brick and block mortar, paver joints and sandboxes.

Top Soil is screened Illinois prairie topsoil, dark and silty, for lawns, grading and bed prep. Fill Dirt raises grade before a CA-6 base course goes down.

Delivery to Coal Valley and the Surrounding Area

Illinois Rock Supply delivers bulk material across Rock Island County, including Moline, Rock Island, East Moline, Silvis and Milan. Coal Valley orders come through the same online checkout as the rest of the county.

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on site in one pile.

Have the drop spot clear before the truck arrives. Once the load is down, work it from the pile at your own pace.

Ground and Conditions in Coal Valley

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

That cycle is what a CA-6 base course is for. The fines in CA-6 let it tighten into a firm, stable surface that holds up through the spring thaw instead of rutting out.

On the loess uplands, gully and rill erosion shows up on steep slopes and ravines, and runoff concentrates where it can cut. Clean washed stone in a drainage trench gives that water a path away from the structure.

Timing matters as much as material. Wet ground will not compact, so plan the base course for a dry stretch and keep the drainage work on its own schedule.
