Landscaping Material Delivered in Iowa City, IA

Iowa Rock Supply handles gravel and aggregate delivery in Iowa City, IA, from Class A roadstone to decorative stone. This part of the Southern Iowa Drift Plain sits on old till under a windblown loess cap, and the clay beneath it holds water instead of taking it.

That ground is why an under-built base shows up first at the bottom of a grade, and why base depth matters before anything else.

A bulk load is heavy, and soft ground after a wet spring will not hold a truck that is already committed.

Materials for Iowa City Projects

Decorative rock carries a lot of the work around here: beds, borders, dry creek beds and ground cover that has to sit still through spring runoff.

Rounded stone is the right shape for that job because it does not lock together or hold a slope, so it belongs in flat beds and lined channels, not on a grade.

River Rock is washed round gravel from the Missouri and Mississippi valleys. It suits decorative beds, borders and dry creek beds.

Large River Rock is the oversized grade of the same rounded stone. Use it for dry creek beds, splash pads and heavier decorative and bank work.

3/8" Natural Pea Gravel is small rounded gravel for walkways, play areas, patio bedding and small drainage runs. Iowa says Natural Pea Gravel.

Limestone Screenings are the fines from crushed limestone. They bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base.

Top Soil is screened black dirt, the dark prairie soil Iowa yards are known for. It goes into lawn repair, grading and bed prep.

Shredded Mulch is double ground hardwood for beds, tree rings and windbreak plantings. It holds moisture through a dry Iowa August.

Ground and Conditions in Iowa City

Across the Southern Iowa Drift Plain the profile is old pre-Illinoian till under a windblown loess mantle, usually 5 to 30 feet thick, with buried paleosols beneath. The Yarmouth-Sangamon paleosol is a thick, gummy grey clay that water will not move through.

Ground like that drains at the surface but perches water below it. Drives go soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.

This is also Iowa's most eroded landscape. Streams cut deeply, hillslopes carry rills, and gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and outlets.

That shapes what you order. A fines-bearing material like Class A Roadstone binds and compacts into a base, but it will not shed water.

Where water needs to move, order an open graded stone instead.

Clean Rock is washed and open graded, so water passes straight through. Riprap is large angular stone for stream bank armoring, culvert outlets, pond edges and slope protection.

The working season here is the longest in the state, but clay has to dry before anything gets compacted on top of it. A wet spring pushes base work back several weeks.

Cold winters bring repeated freeze-thaw, which heaves gravel drives and lanes every spring. Footing depth is set by the local building official.
