Rip Rap and Bulk Aggregates for Waterloo, IL

Illinois Rock Supply handles gravel and aggregate delivery in Waterloo, IL, from a single ton to full truckloads. CA-6 is the base material here: dense graded crushed limestone with the fines left in, used for driveways, parking pads, shed and garage bases and trench backfill.

Waterloo sits in Monroe County, where deep loess covers older drift on rolling uplands and steep ravines cut toward the Mississippi. That ground moves water fast on slopes and holds it in the flats, so what you put on a bank or in a swale matters as much as what you put on a drive.

Materials for Waterloo Projects

Slope, swale and bank protection starts with coarse stone. Heavy broken stone holds a bank, armors a culvert outlet and settles into a pond edge without washing out.

RipRap is the material for that work.

Below the heavy stone, clean washed sizes handle water that has to move. CA-7 is 1 inch clean stone with no fines, for bedding under pipe, drainage trenches, French drains and concrete flatwork.

CA-11 is the 3/4 inch clean washed stone sold alongside it for the same bedding and drainage 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 crushed limestone fines for paver and flagstone bedding and for backfill around pipe.

For surfaces, CA-6 builds the compacted base and Driveway Gravel surfaces an existing drive or tops a compacted base. Walkway Gravel gives paths and garden walks a finer, walkable surface.

Sand and soil round out a Waterloo order. Torpedo sand is coarse washed sand for concrete, leveling and bedding, and mason sand is the fine clean sand for brick and block mortar and paver joints.

Topsoil is screened for lawns, grading and bed prep, and Fill Dirt raises grade before a CA-6 base course goes down.

Ground and Conditions in Waterloo

Work here runs from the spring thaw into late fall, a little longer than upstate. Bottomland sites wait out spring high water, so timing a delivery around the season is part of planning the job.

Across the Western Illinois loess uplands and the Mississippi border, loess sheds water fast on slopes and holds it in the flats. In the sinkhole country water disappears into the ground instead of running to a ditch, so drainage has to be planned rather than assumed.

That drives the erosion pattern: gully and rill erosion in loess on steep bluffs and ravines, slumping on cut slopes, and collapse around sinkholes where runoff concentrates. Coarse stone on those banks and outlets is the practical answer.

Cold winters bring freeze and thaw, and frost still lifts drives and walks each spring. Frost depth in this part of the state runs about 36 to 40 inches, and the local building department sets the figure it uses.
