Crushed Stone, Sand and Gravel in Thomson, IL

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

Materials for Thomson Projects

Base and driveway surfacing comes first. CA-6 is dense graded crushed limestone with the fines left in.

It builds driveways, parking pads, shed and garage bases, and trench backfill.

Driveway Gravel surfaces an existing drive or tops a compacted base. Crusher Run is the same fines-bearing crushed stone under its secondary name.

Washed stone has no fines and stays open for water. CA-7 is 1 inch clean stone for bedding under pipe, drainage trenches, French drains and concrete flatwork.

3/4" Crushed Stone, or CA-11, is the 3/4 inch clean washed stone for bedding and drainage. CA-16 Chips are 3/8 inch chips for permeable paver bedding and drainage around tanks.

Sand and soil round out a project. Torpedo sand is the coarse washed sand for concrete and leveling.

Mason Sand mixes into brick and block mortar and fills paver joints. Top Soil grades lawns and beds, and Fill Dirt raises grade before a CA-6 course goes down.

Decorative options include River Gravel for beds and dry creek beds, plus Large River Rock for downspout splash areas. RipRap armors banks, culvert outlets and pond edges.

Ground and Conditions in Thomson

Across the Driftless and old-drift northwest, water moves fast. Rain and snowmelt run down steep ground into narrow valleys, and springs and seeps come out of the dolomite.

On loess ridges here, heavy rain runs off before it can soak in. That is why a drainage layer matters as much as the base itself on a hillside pad or a steep drive.

Erosion follows the same pattern: gullies and rills in loess on steep slopes, rock fall and slumping on cut banks. Clean stone like CA-7 or rip rap goes where water concentrates.

Work runs from the spring thaw into late fall. A wet spring turns loess greasy, and steep drives and hillside pads are hardest to build then.

Frost works harder on thin soils over rock and on cut slopes in this part of the state. The local building department sets frost depth, and it belongs to the building official, not to a material order.
