Clean Rock Delivery for Selma, IA

If you are pricing gravel and aggregate delivery in Selma, IA, the first question is usually what to put down and how much. Iowa Rock Supply sells bulk material by the ton and delivers it to your site.

Class A roadstone is the crushed limestone base course this part of Iowa builds on, and it is where a drive, a pad or a farm lane starts. The ground under it decides how the job holds up.

Delivery to Selma and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to size the load before you commit.

A dump truck tips the material in one pile at the address you give. From there it is your site and your equipment.

Materials for Selma Projects

Raising grade and building pads is the work this ground asks for first. Old till and loess leave low spots and soft corners, and a pad or a lane that sits below the surrounding grade will hold water until it fails.

Fill dirt goes in first to bring a site up to grade or to fill low ground. It is clay fill or sandy fill, and it is the material that builds the elevation before anything else goes on top.

Order it from Fill Dirt.

Once the grade is where you want it, Class A roadstone is the sub-base. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts into a surface that carries a truck.

Order it from Class A Roadstone.

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.

Order it from 1 Inch Roadstone.

Where water has to move rather than sit, clean rock is washed and open graded. It backfills subdrains, drainage tile and retaining walls, and it beds septic lines.

Order it from Clean Rock.

On top of a compacted base, limestone screenings bed pavers and flagstone and fill the joints. Screened black dirt, which Iowa yards call black dirt, handles lawn repair and bed prep.

Order it from Limestone Screenings or Top Soil.

Ground and Conditions in Selma

Selma sits on the Southern Iowa Drift Plain, where old pre-Illinoian till lies under a windblown loess mantle. Beneath both is a thick grey clay paleosol that water will not move through.

Farmers working it call it gumbo.

That clay is the reason an under-built base shows itself fast. Surface water perches on the clay, runs off the rolling ground, and leaves drives soft at the bottom of a grade.

Spring rain on saturated clay is the worst of it.

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

Riprap armors a bank or a culvert outlet, and clean rock gives water somewhere to go.

The working season here is the longest in the state, but clay has to dry before anything gets compacted. A wet spring pushes base work back several weeks.

Cold winters bring repeated freeze-thaw, and frost heaves gravel drives and lanes every spring.
