Pea Gravel Delivery for Amana, IA

Iowa Rock Supply handles gravel and aggregate delivery in Amana, IA, and the ground here asks for material that behaves. Class A roadstone is the crushed limestone base course with the fines left in, so it binds and compacts.

On the Southern Iowa Drift Plain, that matters.

Materials for Amana Projects

Decorative rock carries a lot of ground here, from bed cover to dry creek beds. River rock is rounded gravel washed out of the Missouri, Mississippi and their tributary valleys.

It suits decorative beds, borders and dry creek beds.

Large river rock is the oversized grade of the same rounded stone. It goes into dry creek beds, splash pads and heavier decorative and bank work.

For a soft, walkable surface, 3/8 inch natural pea gravel covers walkways, play areas and patio bedding.

Where a bed meets a lawn, shredded hardwood mulch holds moisture through a dry Iowa August. It works in beds, tree rings and windbreak plantings.

For a driveway or a parking pad, Class A roadstone is the standard base course. It is crushed limestone with the fines left in, and it binds under a compacted surface.

1 inch roadstone is the coarser grade, laid under a finer surface course on a new drive or a lane that carries heavy equipment. Driveway gravel tops an existing drive that has thinned out.

For drainage, clean rock is washed and open graded, so water moves straight through. It goes into subdrains, drainage tile backfill, pipe bedding and backfill behind retaining walls.

Limestone screenings bed pavers and flagstone and fill joints. Riprap armors stream banks, culvert outlets and pond edges against spring runoff.

Ground and Conditions in Amana

This part of Iowa sits on old pre-Illinoian till under a windblown loess mantle. Beneath that is the Yarmouth-Sangamon paleosol, a thick, gummy grey clay that water will not move through.

Farmers call working in it gumbo.

Ground on the Southern Iowa Drift Plain drains at the surface, but the clay subsoil does not take water. It perches, runs off and leaves drives soft at the bottom of a grade.

Spring rain on saturated clay is the worst of it.

This is Iowa's most eroded landscape. Streams cut deeply and hillslopes carry a fine texture of rills.

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

An under-built base shows up fast in that clay. Class A roadstone binds and compacts into a base that holds up where fill dirt alone would pump and rut.

Clay soils need to dry before anything gets compacted, so a wet spring pushes base work back several weeks. Cold winters bring repeated freeze-thaw, enough to heave gravel drives and lanes every spring.
