Crushed Stone, Sand and Gravel in Ottawa, IL

Illinois Rock Supply handles gravel and aggregate delivery in Ottawa, IL, from base stone to bedding sand. CA-6, the dense graded crushed limestone this part of Illinois calls road base, is the starting point for most drives and pads here.

Around Ottawa the ground runs sandy, so what you put under a drive matters as much as what you spread on top.

Materials for Ottawa Projects

Base and driveway surfacing is where a project in Ottawa usually begins, and CA-6 leads it. CA-6 is crushed limestone with the fines left in, so it packs into a firm, tight surface for driveways, parking pads, shed and garage bases, and trench backfill.

If you need a looser surface on top of a compacted base, Driveway Gravel and Walkway Gravel give you a finer, more walkable finish for paths and garden walks. Crusher Run is the same idea as CA-6 under a secondary name.

Washed stone has no fines, so it stays open and lets water move. CA-7 is the one inch clean stone used for bedding under pipe, drainage trenches, French drains and concrete flatwork.

CA-11 is the 3/4 inch clean stone sold alongside it for the same bedding and drainage work. CA-7 and 3/4" Crushed Stone cover both sizes.

For tighter work, CA-16 Chips are 3/8 inch limestone chips for permeable paver bedding, drainage around tanks, and topping a compacted base. Lime Screenings are the crushed limestone fines that bed pavers and flagstone and backfill around pipe.

Sand covers the wet work. Torpedo sand is the coarse washed sand Illinois yards sell for concrete, leveling and bedding, listed as Washed Sand.

Mason sand is finer and cleaner, for brick and block mortar, paver joints, sandboxes and volleyball courts.

Soil, fill and decorative stone round out an order. Topsoil here is dark and silty, sold screened for lawns, grading and bed prep.

Garden soil fills raised beds and vegetable plots, and fill dirt raises grade before a CA-6 base course goes down. Natural Pea Gravel and river gravel handle walkways, play areas and dry creek beds.

Ground and Conditions in Ottawa

Start with where the water goes. Across the Illinois River valley and the sand areas, the ground takes water quickly and holds almost none, so a base that washes and settles is the real problem rather than one that stays wet.

That changes how you build. A drive on loose sandy ground needs a base course that knits together and stays put, which is what CA-6 does with its fines left in.

Wind moves bare sand, and water running across a loose sandy drive cuts ruts. Both are reasons to surface a drive rather than leave it raw.

On the low bottoms, the Illinois River coming up floods ground that sits close to the water, so plan those projects around the river level.

The sandy ground dries and works early in the spring, and river bottoms stay off limits during high water. Cold winters bring repeated freeze and thaw, though open sand drains well and heaves less than the clay ground on the uplands either side.

Work runs into late fall.
