Across the Southern Iowa Drift Plain, clay subsoil sheds spring rain instead of taking it. Water perches, runs off and leaves drives soft at the bottom of a grade.

Materials for Norwalk Projects

Decorative rock carries the look of a yard here, and it does real work on the ground. Rounded stone in a bed, along a border or down a dry creek bed holds the shape of the space.

For a dry creek bed or a heavier bank edge, Large River Rock is the oversized rounded stone. It sits well in a wide channel that carries runoff.

For beds, borders and smaller dry creek beds, River Rock is the washed rounded gravel. Rounded stone stays loose, so use it as cover, not as a base.

Ground cover under trees and along a fence line starts with Shredded Mulch. It holds moisture through a dry Iowa August.

Then match the material to the job. A driveway, a patio and a drain each want a different stone.

Driveways and lanes take Class A roadstone over a compacted layer. A new drive or a soft spot may want the coarser 1 inch roadstone under a finer surface course.

For a patio, limestone screenings bed the pavers and fill the joints. For a drain, clean rock lets water move straight through instead of holding it.

Ground and Conditions in Norwalk

This part of the state sits on old pre-Illinoian till under a windblown loess mantle. Beneath that, a thick grey clay paleosol stops water cold, and farmers call working in it gumbo.

That clay is why an under-built base shows up fast. Water perches on the clay, runs off the slope and softens the ground at the bottom of a grade.

This is Iowa's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and gully and stream bank erosion after heavy rain puts rock on slopes and at culvert outlets.

Spring rain on saturated clay is the worst of it, so a wet spring pushes base work back several weeks. Clay soils need to dry before anything gets compacted.

Cold winters bring repeated freeze-thaw, enough to heave gravel drives and lanes every spring.

Riprap armors a stream bank or a pond edge against that runoff. On a slope or at a culvert outlet, it takes the energy out of moving water.
