Materials for Dawson Projects

Drainage is where most of the material decisions start around here. Washed stone is the open graded family: the fines are washed out, so water moves straight through instead of sitting in the pile.

Washed Stone for Drains and Drywells

Clean Rock is the one to know for subdrains, drainage tile backfill, pipe bedding and septic rock. It comes as 1 inch clean or 1 1/2 inch clean, and it stays open under the weight of backfill.

For French drains and downspout runs, 3/4" Crushed Stone is a smaller clean option. It also works as pipe bedding and trench backfill where a free draining stone is wanted.

3/8" Crushed Stone is washed chips, the finest of the clean grades. Iowa quarries sell it for paver joints, fine drainage and a thin top dressing.

Base, Bedding and Surface Materials

Once the water has somewhere to go, the base goes down. Class A roadstone is the standard Iowa base course for driveways, parking pads, shed bases and farm lanes.

A new drive or a soft spot may want 1 Inch Roadstone underneath, a coarser roadstone for lanes that carry heavy equipment. Limestone Screenings bed pavers and flagstone and fill the joints.

Riprap, sold locally as revetment stone, protects banks and culvert outlets against spring runoff. Washed sand beds and levels under slabs and pavers.

Screened black dirt handles lawn repair, grading and bed prep.

Ground and Conditions in Dawson

Start with the working season, because it decides when a load can go down. 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. A wet spring shortens that window, so timing a delivery matters as much as the material itself.

The ground here is thick, compact pebbly loam till of the Dows Formation, 45 to 60 feet deep. This is pothole country: the drainage network is young, kettles and closed depressions hold water, and most ground drains only because it is tiled.

That is why a drainage layer earns its place. Snowmelt and spring rain sit on the surface where the ground below is still frozen, and washed stone gives that water a path.

Erosion on the Des Moines Lobe shows up as ditch and tile outlet scour and washouts where runoff concentrates. Riprap at an outlet or a bank holds that ground in place.
