Kanawha sits in Hancock County, on the Des Moines Lobe, where thick glacial till and flat, tiled ground shape how a base is built.

Materials for Kanawha Projects

Start with the base. Class A roadstone is the crushed limestone base course with the fines left in, so it binds and compacts under a drive, a parking pad, a shed base or a farm lane.

Where a new drive or a soft spot needs a coarser start, 1 inch roadstone goes down first and carries heavy equipment. 1 Inch Roadstone is the grade to lay under a finer surface course.

Class A Roadstone and Driveway Gravel handle most surfacing work. Driveway Gravel tops an existing drive or lane that has thinned out over a compacted base.

Washed stone is the other half of the work. Clean rock is washed and open graded, so water moves straight through it: subdrains, drainage tile backfill, pipe bedding, septic rock and backfill behind retaining walls.

Clean Rock and 3/8" Crushed Stone cover drainage and fine surfacing. Iowa quarries sell the 3/8 inch washed stone as washed chips, for seal coat aggregate, paver joints and a thin top dressing.

Limestone screenings are the fines, used for paver and flagstone bedding, joint filling and a fine top dressing over a compacted roadstone base. Limestone Screenings finish the surface layer.

Sand and soil round out a site. Mason sand mixes brick and block mortar and beds paver joints.

Washed sand beds and levels under slabs and pavers. Screened topsoil, which Iowa yards call black dirt, repairs lawns and preps beds.

For decorative work, river rock and Natural Pea Gravel dress beds and walkways. Shredded hardwood mulch holds moisture through a dry Iowa August.

Ground and Conditions in Kanawha

This is pothole country. Across the Des Moines Lobe the drainage network is young and inefficient, and kettles and closed depressions hold water.

Most of the ground only drains at all because it is tiled. Snowmelt and spring rain sit on the surface where the ground below is still frozen.

That changes what a base has to do. Water that cannot move down has to move sideways, so drainage stone and a compacted roadstone course matter more than slope.

Erosion here is less about hillsides and more about ditch and tile outlet scour, plus washouts where runoff concentrates on the moraine ridges. Riprap armors culvert outlets, pond edges and slope faces against spring runoff.

Compaction waits for the frost to come out and for 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.

Long, cold winters bring repeated freeze and thaw that heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
