Bulk Gravel Delivery to Farmington, IA

If you are planning gravel and aggregate delivery in Farmington, IA, the job usually starts with what goes under the finished surface. Iowa Rock Supply sells bulk material by the ton and delivers it to your site in Van Buren County.

Class A roadstone is the crushed limestone base course with the fines left in, so it binds and compacts. Around here it goes under driveways, parking pads, shed bases and farm lanes, and it is the layer everything else sits on.

Ground and Conditions in Farmington

Across the Southern Iowa Drift Plain, old till sits under a windblown loess mantle. Below that, a thick grey paleosol behaves like gumbo, and water will not move through it.

Ground that steeply rolling drains at the surface but perches on that clay. Drives go soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.

A thin base is where those drives fail first. The surface stone disappears into the soft ground and the drive turns to rutted mud, so the fix is more base material rather than more topping.

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

Clay soils have to dry before anything gets compacted. A wet spring pushes base work back several weeks, and the working season here is the longest in the state.

Winters bring repeated freeze-thaw, milder than northern Iowa but still enough to heave gravel drives and lanes every spring. Frost depth commonly reaches 42 inches, though the local building official sets footing depth.

Materials for Farmington Projects

Bedding under pavers and flatwork is where the material choice shows up fastest. The bedding layer has to be fine, uniform and easy to screed so the pavers sit flat and stay put.

Limestone screenings, also called 3/8 inch minus screenings, are the usual bedding for pavers and flagstone. They also fill joints and work as a fine top dressing over a compacted roadstone base.

Limestone Screenings are the fines left from crushing.

Washed sand is the other bedding choice, used for leveling under slabs and pavers and as sand fill where a clean, free draining grade is wanted. See Washed Sand for that work.

Mason sand mixes tighter for brick and block mortar, paver joints, play sand and horse arena footing. It is sold as Mason Sand.

Under the bedding, Class A roadstone carries the load. Class A Roadstone is crushed limestone with the fines left in so it binds and compacts into a base for drives, pads and farm lanes.

Where a new drive or a lane carrying heavy equipment needs a coarser start, 1 inch roadstone goes down under a finer surface course. Order it as 1 Inch Roadstone.

For drainage, clean rock is washed and open graded, so water moves straight through it. It backfills subdrains, drainage tile, pipe bedding and septic systems, and it goes behind retaining walls.
