Pea Gravel, Stone and Soil Delivery in Sandwich, IL

Water is the problem on flat ground in this part of the state, and washed stone is the answer. Illinois Rock Supply brings gravel and aggregate delivery in Sandwich, IL, starting with CA-6 for the base and clean stone for everything that has to drain.

Spring snowmelt and rain on frozen ground push water sideways across the surface. A driveway that holds that water turns soft fast.

Materials for Sandwich Projects

Washed stone carries water instead of holding it. CA-7 is 1 inch clean stone with no fines, and it beds pipe, lines drainage trenches and sits under concrete flatwork.

CA-11 is the 3/4 inch clean washed stone that goes with it, for bedding and drainage. CA-16 chips run 3/8 inch and bed permeable pavers.

CA-5 is the largest clean size, for trench bottoms and heavy drainage.

For a French drain or a drywell, clean stone is the whole point. Fines would seal the voids and stop the water.

Keep the washed sizes washed.

CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in. It builds driveways, parking pads, shed and garage bases and trench backfill.

Lime screenings are the bedding layer under pavers and flagstone. Torpedo sand is the coarse washed sand for concrete and leveling.

Mason sand is finer, for brick and block mortar and paver joints.

For ground cover, Top Soil grades lawns and beds, and Shredded Mulch holds moisture through a northern Illinois summer.

Ground and Conditions in Sandwich

The working season runs from the spring thaw into late fall, a little shorter than downstate. Frozen ground stops compaction in the winter, so time a delivery around the thaw.

Across the Northern Illinois till plains and Rock River country, tight till and a high water table sit on the flat ground. Sand plains nearby drain almost too fast.

Both conditions argue for clean stone where water has to move.

Winters here bring repeated freeze and thaw and heavy frost action in unbound base and shallow footings. Frost depth runs about 42 inches across the northern counties, and the local building department sets the figure that applies to your job.

Gully and sheet erosion shows up on steeper slopes in this part of the state. RipRap armors banks, culvert outlets and pond edges, and holds where moving water scours.
