Materials for Rock Island Projects

Raising grade and building a pad is the work that sets up everything else on a lot. When the ground is low or uneven, bulk fill goes down first so the finished surface has something solid under it.

Fill Dirt is the bulk material for lifting grade before a base course goes on. It builds up the elevation so a driveway, shed or garage pad sits where you need it.

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

A driveway build usually starts with fill, then a compacted CA-6 base, then a surface course on top.

Driveway Gravel surfaces an existing drive or tops a compacted base. On a new drive, CA-6 carries the load and the surfacing stone finishes it.

For a patio or walk, the bedding layer matters as much as the base. Lime Screenings are the crushed limestone fines used to bed pavers and flagstone, and to backfill around pipe.

Drainage work takes clean stone instead. CA-7 is washed stone with no fines, used under pipe, in drainage trenches and French drains, and around concrete flatwork.

3/4" Crushed Stone is the CA-11 size that pairs with it for bedding and concrete work.

Ground and Conditions in Rock Island

Across the Western Illinois loess uplands and the Mississippi border, the ground is deep loess over older drift, with dissected bluffs and steep ravines. Loess sheds water fast on slopes and holds it in the flats.

That matters to a base. A pad built on soft, wet ground moves, and the surface on top of it follows.

Fill that raises grade gives you a starting elevation, and CA-6 over it gives you a base that carries weight.

Erosion shows up as gullies and rills on steep ground, and as slumping on cut slopes. Water that concentrates instead of spreading does that work.

Work here runs from the spring thaw into late fall, a little longer than upstate. Cold winters bring freeze and thaw, and frost still lifts drives and walks each spring.

Questions About Ordering in Rock Island

What is the best base under pavers in Rock Island?

A compacted CA-6 base is what pavers sit on here, because it is the dense graded crushed limestone Illinois specifies for the job. Over that, lime screenings make the bedding layer, and they are the standard paver and flagstone bed in this state.

The fill below the base is what carries the load, so start there if the ground is low.
