Large River Rock and Bulk Aggregates for Whittemore, IA

Iowa Rock Supply brings gravel and aggregate delivery in Whittemore, IA, with Class A roadstone as the base course most drives and pads start from. Across the Des Moines Lobe, the ground is thick pebbly loam till over old meltwater channels.

That till holds water, so a drive needs a base that sheds it.

Materials for Whittemore Projects

Coarse, angular stone is what protects a slope, a swale or a stream bank on this ground. Water that concentrates on the moraine ridges cuts wherever it runs, so the oversized stone does the armoring work.

Riprap, sold locally as revetment stone or Class D revetment, goes on stream banks, culvert outlets, pond edges and any slope facing spring runoff.

Large river rock and river rock, also called washed river gravel, are the other option for bank work and dry creek beds. The rounded stone spreads the flow and holds the soil behind it.

Both sizes suit splash pads and heavier decorative edges.

Below the coarse sizes, the grades step down. Clean rock, called clean stone or 1 inch clean, is washed and open graded, so water moves straight through it.

Use it in subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

Class A roadstone is the 3/4 inch crushed limestone base course with the fines left in, so it binds and compacts. Iowa Rock Supply delivers it for driveways, parking pads, shed bases and farm lanes.

Where a drive is new or a lane carries heavy equipment, 1 inch roadstone lays a coarser course under a finer surface. 1 Inch Roadstone handles that first pass.

For the fine end, limestone screenings bed pavers and flagstone and fill the joints. Limestone Screenings also top-dress a compacted roadstone base.

Ground and Conditions in Whittemore

Timing drives most of the work on the Des Moines Lobe. This is pothole country, where the drainage network is young, kettles and closed depressions hold water, and most ground only drains because it is tiled.

Snowmelt and spring rain sit on the surface while the ground below is still frozen.

Compaction waits for the frost to come out and the flat ground to shed its spring water. Base and paver work runs from late spring to the fall freeze, and a wet spring shortens that window.

Plan the delivery against that window rather than against the calendar.

The ground is thick, compact pebbly loam till, and it holds water well. That is why a drainage layer under a base matters here, and why coarse stone on a slope or swale does more than a finer grade would.
