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

Materials for North Liberty Projects

Base and driveway surfacing come first here. Class A roadstone is the standard Iowa base course, crushed limestone with the fines left in so it knits together under traffic.

For a new drive, a soft spot or a lane that carries heavy equipment, 1 Inch Roadstone is the coarser grade. It goes down under a finer surface course.

Washed stone is the other half of the work. Clean Rock is washed and open graded, so water moves straight through it.

Use it for subdrains, pipe bedding, septic rock and backfill behind retaining walls.

3/8" Crushed Stone is the washed chips Iowa quarries sell for seal coat aggregate, fine drainage and paver joints. Limestone Screenings are the fines, and they bed pavers and flagstone and fill the joints between them.

Sand and soil finish the job. Washed Sand beds and levels under slabs and pavers.

Top Soil is screened black dirt for lawn repair, grading and bed prep.

Ground and Conditions in North Liberty

Water drives everything here. Rain and spring snowmelt run off rolling ground and then stop, because the clay subsoil will not take them.

Across the Southern Iowa Drift Plain, old till sits under a windblown loess mantle. Beneath that is a thick, gummy grey clay that water will not move through, and it perches and runs off instead.

That is why drives go soft at the bottom of a grade. It is also why a drainage layer matters more than a thicker surface in the wet spots.

This is Iowa's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and gully and bank erosion after heavy rain is the reason rock goes in on slopes and culvert outlets.

Clay soils need to dry before anything gets compacted, so a wet spring pushes base work back several weeks. Southern Iowa has the longest working season in the state, but the ground sets the schedule.

Cold winters bring repeated freeze and thaw. Frost depth is commonly 42 inches, and the local building official sets footing depth.

That heave works on gravel drives and lanes every spring.
