Bulk Material Delivery in Lewis, IA

If you need gravel and aggregate delivery in Lewis, IA, Iowa Rock Supply sells bulk material by the ton and drops it at your site. Class A roadstone is the crushed limestone base course most drives and pads here start from.

The ground underneath decides how that base behaves. Old till sits under a windblown loess mantle across the Southern Iowa Drift Plain, and a gummy grey clay beneath it holds water instead of taking it.

Materials for Lewis Projects

Water is the practical problem on a lot in this part of Cass County. Clay subsoil perches it, so it runs off, pools at the bottom of a grade and finds every low spot.

Washed stone is how you move it along.

Clean rock is washed and open graded, so water passes straight through it. Use it for French drains, drywells, downspout runs, subdrains and pipe bedding.

Clean Rock is the material for a trench that has to stay open.

3/4 inch clean stone does similar work at a smaller size. It suits drive surfacing where you want a loose, free draining surface, plus pipe bedding and trench backfill.

3/4" Crushed Stone stays open because the fines are washed out.

3/8 inch washed chips are the fine end of the washed family. Iowa quarries sell this as washed chips, and it works for seal coat aggregate, paver joints and thin top dressing.

3/8" Crushed Stone is a small, clean stone.

Above those sizes, 1 inch roadstone is the coarser grade. It goes under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

1 Inch Roadstone is crushed limestone with the fines left in, so it binds and compacts.

For the surface itself, Class A roadstone is the standard base course. It handles driveways, parking pads, shed bases and farm lanes.

Class A Roadstone is the 3/4 inch crushed limestone base with the fines left in.

Limestone screenings are the fines, and they bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Limestone Screenings are a fine, binding material.

Ground and Conditions in Lewis

Start with the working season. This part of Iowa gets the longest working season in the state, but clay soils need to dry before anything gets compacted.

A wet spring pushes base work back several weeks.

That timing matters because the subsoil does not drain. Water perches on the clay, runs off and leaves drives soft at the bottom of a grade.

Spring rain on saturated clay is the worst of it.

Erosion follows the same pattern. This is Iowa's most eroded landscape, with streams cut deep and hillslopes carrying a fine texture of rills.

Gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and outlets.

Riprap is the answer on a bank or an outlet. It armors stream banks, culvert outlets, pond edges and slopes against spring runoff.

Riprap is the large angular stone for that work.

Freeze and thaw heaves gravel drives and lanes every spring. A frost depth of 42 inches is commonly used in this part of the state, and the local building official sets footing depth.
