Materials for Corydon Projects

Decorative rock and ground cover do a lot of the finishing work on Corydon yards. Rounded stone and washed chips dress beds, borders and dry creek beds, and they hold up through an Iowa August.

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, for dry creek beds, splash pads and heavier decorative and bank work.

3/8" Natural Pea Gravel covers walkways, play areas, patio bedding and small drainage runs. 3/8" Crushed Stone, sold locally as washed chips, is a seal coat aggregate and works for fine drainage, paver joints and a thin top dressing.

Limestone Screenings bed pavers and flagstone, fill joints and top dress a compacted roadstone base. Under a patio or a shed, Class A Roadstone is the compacted base that takes the load.

Ground and Conditions in Corydon

Across the Southern Iowa Drift Plain, old pre-Illinoian till sits under a windblown loess mantle, usually 5 to 30 feet thick. Beneath it are buried paleosols, and the Yarmouth-Sangamon is a thick, gummy grey clay that water will not move through.

That clay is why ground here drains at the surface but not below it. Water perches, runs off and leaves drives soft at the bottom of a grade, and 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, so 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 on that ground. Clean, open graded stone lets water move straight through instead of sitting against the clay, which is what Clean Rock and Riprap are for.

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

Cold winters bring repeated freeze-thaw, milder than the north but still enough to heave gravel drives and lanes every spring. Frost depth in the Southern Iowa Drift Plain is commonly 42 inches, and the local building official sets footing depth.
