Most ground here starts with Class A roadstone, the crushed limestone base course that binds and compacts under a drive or a pad.

This is pothole country. The ground under Des Moines holds water in closed depressions and only sheds it because it is tiled, so what you put on top has to move water away.

Washed stone is where a lot of wet ground gets solved. Clean, open graded stone has no fines in it, so water runs straight through instead of sitting.

Use it for French drains, drywells, downspout runs and subdrain backfill.

Start with the coarse end. #4 Crushed Stone handles heavy drainage, construction entrances and trench bottoms, and Clean Rock covers subdrains, pipe bedding, septic rock and backfill behind retaining walls.

Then the smaller washed sizes. 3/4" Crushed Stone surfaces drives that want a loose, free draining layer, and 3/8" Crushed Stone works as seal coat aggregate, in paver joints and as a thin top dressing.

For a base that has to hold, go the other way. Class A Roadstone is crushed limestone with the fines left in, which is what lets it bind and compact under driveways, parking pads, shed bases and farm lanes.

Ground and Conditions in Des Moines

Timing decides most of the work here. 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.

Under Des Moines, the ground is thick, compact pebbly loam till, with sand and gravel along old meltwater channels. Across the Des Moines Lobe, kettles and closed depressions hold water, and snowmelt and spring rain sit on the surface where the ground below is still frozen.

That is why a drainage layer earns its place before you surface anything. Clean rock under a downspout run or a French drain gives meltwater somewhere to go instead of working back up through a base.

Long, cold winters and repeated freeze-thaw heave gravel drives, lanes and field entrances as the ground lets go in spring. Spring runoff also scours ditch and tile outlets and cuts stream banks, which is where rip rap comes in.
