Start with Class A roadstone, the crushed limestone base course this market builds drives and pads on. Wet ground in Polk County pushes a lot of work toward washed stone instead.

Materials for Polk City Projects

Drainage is the job that sets the material list here. A wet spring leaves the flat ground holding water, so a downspout run, a French drain or a drywell has to move that water away from the house.

Clean rock is crushed limestone with the fines washed out, so it stays open and lets water pass straight through. That is the stone for a French drain, a drywell, a downspout run or pipe bedding.

It is also the backfill behind a retaining wall.

Clean stone grades by size. Clean Rock covers the 1 inch and 1 1/2 inch sizes.

Below that sits 3/4" Crushed Stone, a washed stone for drive surfacing where you want the surface to drain, and for trench backfill. At the fine end, 3/8" Crushed Stone is the washed chips Iowa quarries sell for paver joints and fine drainage.

Where the ground needs to be built up before anything drains, the answer is a fines-bearing material instead. Class A Roadstone is crushed limestone with the fines left in, so it binds and compacts into a base under a drive, a parking pad, a shed base or a farm lane.

1 Inch Roadstone is the coarser grade of the same idea. It suits a new drive, a soft spot, or a lane that carries heavy equipment, laid under a finer surface course.

For a decorative bed or a dry creek bed, river rock and large river rock are the rounded option. Both are washed river gravel out of the big valley systems.

Sand and soil round out a job. Mason sand sets brick and block mortar and beds pavers.

Top soil, screened black dirt to most Iowa yards, handles lawn repair and grading. Shredded hardwood mulch holds moisture in a bed through a dry August.

Ground and Conditions in Polk City

Polk City sits on the Des Moines Lobe, the youngest glacial ground in Iowa. The till under it is thick, compact and pebbly, laid down 45 to 60 feet deep, with sand and gravel strung along old meltwater channels.

That ground is pothole country. The drainage network is young and inefficient, kettles and closed depressions hold water, and much of the ground only drains because it is tiled.

Snowmelt and spring rain sit on the surface where the ground below is still frozen.

Erosion across the Des Moines Lobe shows up less on slopes and more at ditch and tile outlets, where runoff concentrates. It cuts banks and washes out where water gathers.

Timing follows the ground. Compaction waits for the frost to come out and for the flat ground to shed its spring water.

Base work and paver work run from late spring to the fall freeze, and a wet spring shortens that window.

Winters here are long and cold, and repeated freeze and thaw heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth is commonly 42 inches around the Des Moines Lobe.

The local building official sets footing depth, and northern jurisdictions may ask for more.
