Materials for Seneca Projects

Fill and sub-base come first when you are raising grade or building up a pad. Fill Dirt brings a low area up to grade, and CA-6 goes over it as the compacted base course for a drive, a parking pad or a shed floor.

CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in.

CA-6 handles driveways, parking pads, garage and shed bases and trench backfill.

For a driveway, Driveway Gravel surfaces an existing drive or tops a compacted base. Crusher Run is the secondary name for the same fines-in crushed stone.

For a patio, Lime Screenings bed pavers and flagstone. Lime screenings are crushed limestone fines, and they are the standard bedding layer in Illinois.

For a drain, clean washed stone lets water through. CA-7 is washed clean stone with no fines, for bedding under pipe, drainage trenches and French drains.

3/4" Crushed Stone, sold as CA-11, covers the same bedding and drainage work.

Around tanks and under permeable pavers, CA-16 Chips give you small 3/8 inch chips. Washed Sand, which Illinois yards call torpedo sand, is the coarse washed sand for concrete and leveling.

Ground and Conditions in Seneca

Across the Northern Illinois till plains and Rock River country, the ground runs to tight till and loamy prairie soils over dolomite. On flat ground the water table sits high, and snowmelt and spring rain on frozen ground push water across the surface.

An under-built base over that ground moves. Fill Dirt raises the grade first, then CA-6 goes down as the compacted base course on top.

Where a base is left thin over tight till, water sits in it and the surface breaks up. A clean washed stone layer such as CA-7 or CA-11 gives that water somewhere to go before it reaches the base.

Working conditions run from the spring thaw into late fall. Frozen ground stops compaction in winter, so base work waits for a thaw.

Winters here bring repeated freeze and thaw and heavy frost action in unbound base and shallow footings. Frost depth is set by the local building department.

Questions About Material in Seneca

What is the best base under pavers in Seneca?

Lime Screenings are the standard bedding layer under pavers in Illinois, laid over a compacted CA-6 base. CA-6 is dense graded crushed limestone with the fines left in, so it compacts into a firm base course.

The screenings go on top as the fine bedding layer that lets you set pavers level.
