This is Des Moines Lobe ground, young glacial till that holds water in every low spot. That shapes what you put down and how you time it.

Materials for Collins Projects

Water is the thing to plan around here. Closed depressions hold it, the ground below stays frozen late, and a wet spring pushes runoff across flat ground.

Washed stone is the answer to most of that, because it is open graded and water moves straight through it.

Clean rock, which Iowa yards also call clean stone, is the workhorse for that job. Use it for French drains, drywells, downspout runs, subdrains and pipe bedding.

It comes washed and open graded, so it never silts up the way a fines-bearing material would.

For a finer drainage layer, 3/4" Crushed Stone works as drive surfacing where you want a loose, free draining surface. It also beds pipe and backfills trenches.

At the small end, 3/8" Crushed Stone is the washed chips Iowa quarries sell for seal coat aggregate, paver joints and a thin top dressing. It drains well and stays put in tight spaces.

Not every load is washed. Class A Roadstone is crushed limestone with the fines left in, so it binds and compacts into a firm base for driveways, parking pads and farm lanes.

1 Inch Roadstone is the coarser grade, laid under a finer surface course on a new drive or a lane that carries heavy equipment.

Where the ground needs to shed water before anything goes on top, Clean Rock and Riprap cover the two ends of the scale. Riprap, also sold as revetment stone, armors culvert outlets, pond edges and stream banks against spring runoff.

Delivery to Collins and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load in one pile at your site.

That is the whole of it.

Iowa Rock Supply delivers across Story County, so a site in Collins is covered along with Ames, Nevada, Huxley, Story City and Slater. Whether the drop is a farm lane, a new build or a repair in town, the order works the same way.

Have the pile spot in mind before the truck arrives. Bulk material lands where it is tipped, and moving it afterward is your own work.

Ground and Conditions in Collins

Timing matters more than anything else on Des Moines Lobe ground. Compaction waits for the frost to come out and for 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.

The soil here is thick, compact pebbly loam till, tens of feet deep, with sand and gravel along old meltwater channels. Kettles and closed depressions hold water, and most ground only drains because it is tiled.

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

Erosion shows up less on slopes than in ditch and tile outlet scour, plus washouts where runoff concentrates on the moraine ridges. That is where riprap and clean rock earn their place.

Winters are long and cold, with repeated freeze and thaw that heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth in this part of Iowa is commonly 42 inches.

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