Bulk Material Delivery in Harmon, IL

Illinois Rock Supply handles gravel and aggregate delivery in Harmon, IL, and the ground here shapes what you order. This is till plain country, loamy prairie soil over dolomite, and it holds water after snowmelt and spring rain.

That is why CA-6, the dense graded crushed limestone with the fines left in, is the base material for drives, pads and shed floors. It compacts into a firm surface instead of shifting under a load.

Materials for Harmon Projects

Coarse stone does the heavy work on slope, swale and bank protection around Harmon. The largest clean sizes hold a bank in place and let water move through instead of running over the top.

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

#4 Crushed Stone is large clean stone for construction entrances, heavy drainage and trench bottoms.

Below that size, the washed stone takes over. CA-7 is 1 inch clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.

3/4" Crushed Stone is CA-11, the 3/4 inch clean washed stone Illinois yards sell alongside CA-7 for bedding, drainage and concrete work.

At the fine end, 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.

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

Ground and Conditions in Harmon

Plan around the working season. It runs from the spring thaw into late fall, a little shorter than downstate, and frozen ground stops compaction in winter.

Across the Northern Illinois till plains and Rock River country, tight till and a high water table sit under the flat ground, while sand plains drain almost too fast. Snowmelt and spring rain on frozen ground push water across the surface.

On the steeper slopes, gully and sheet erosion cut into bare ground, and bank scour works on the rivers. That is the case for coarse stone on swales and banks rather than soil alone.

Frost action is heavy here in unbound base and shallow footings, with repeated freeze and thaw. Frost depth runs about 42 inches across the northern counties, and the local building department sets it.
