Fill and Base Material Delivered in Harper, IA

Iowa Rock Supply brings gravel and aggregate delivery in Harper, IA to driveways, building pads and farm lanes. Class A roadstone is the base course this market builds on.

It is crushed limestone with the fines left in, so it binds and compacts. The ground here sits on old till under a loess mantle, which shapes what a base has to do.

Materials for Harper Projects

Fill and sub-base carry a lot of the work here, because raising grade and building up a pad comes before any surface goes down. Fill dirt is clay or sandy fill for lifting low ground and backfilling ahead of a roadstone course.

Once the grade is where you want it, Class A roadstone goes on top as the compacted base. It is crushed limestone with the fines left in, and it binds under a drive, a parking pad, a shed base or a farm lane.

For a new drive or a lane that carries heavy equipment, 1 inch roadstone is the coarser grade. It goes down under a finer surface course, and it also fills a soft spot.

Where water needs to move instead of sit, clean rock is washed and open graded. It goes in subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

For the surface itself, driveway gravel tops an existing drive or lane that has thinned out. It sits over a compacted roadstone base.

Ground and Conditions in Harper

Across the Southern Iowa Drift Plain, the ground is old pre-Illinoian till under a windblown loess mantle. Beneath that sits a thick, gummy grey clay that water will not move through.

So the surface drains but the subsoil does not. Water perches, runs off, and leaves a drive soft at the bottom of a grade.

An under-built base is what fails first on that ground. Fill and roadstone have to bring the grade up and hold it, or spring rain on saturated clay works the surface loose.

This is also the state's most eroded landscape. Streams cut deep, hillslopes carry rills, and gullies open after heavy rain, which is why rock goes in on slopes and at culvert outlets.

The working season here runs long, but clay has to dry before anything gets compacted. A wet spring pushes base work back several weeks.

Freeze-thaw heaves gravel drives and lanes each spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
