Ground and Conditions in Rock Valley

Across the Northwest Iowa Plains, older glacial deposits sit under a loess mantle that thins toward the northeast. Long, even slopes are the result, and silt loess on those slopes rills and gullies quickly under hard rain.

A thin base shows that first. The surface rutts, the edges break away, and the fines wash out of the crown within a season.

The fix is a compacted Class A roadstone course with the fines left in so it binds. Water then sheds off the surface instead of cutting into it.

This is the driest corner of Iowa, with heavy storms arriving as short, hard events. Runoff speed is the problem here, not standing water.

Winters run cold and open, and wind drives frost deep. That heaving works on gravel surfaces through the spring thaw, so a base that binds holds its shape better than a loose one.

Once frost is out, the working season is long. Drying winds and low rainfall mean new base and new seeding both need water held on them.

Materials for Rock Valley Projects

Limestone screenings do the fine work on paths and walkways. These are the 3/8 inch minus fines, and they bed pavers and flagstone, fill joints, and dress the top of a compacted roadstone base.

Screenings knit together underfoot and give a path a firm, walkable surface. Use Limestone Screenings for garden paths, paver bedding and joint filling.

Under the walking surface, Class A roadstone carries the load. It is crushed limestone with the fines left in, so it binds and compacts into a base for driveways, parking pads, shed bases and farm lanes.

Order Class A Roadstone for that course.

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.

Where water has to move, clean rock is washed and open graded so it drains straight through. It backfills subdrains, drainage tile, pipe bedding and retaining walls.

Use Clean Rock for those runs.

For a loose, free draining drive surface, 3/4 inch clean stone works well. It also beds pipe and backfills trenches.

Choose 3/4" Crushed Stone.
