Order gravel and aggregate delivery in Greenfield, IA, by the ton or the yard. Iowa Rock Supply drops bulk material at your site, and Class A roadstone is the base most of that work starts on.

Greenfield sits on the Southern Iowa Drift Plain, where windblown loess covers old till. That ground shapes what a patio, drive or pad needs underneath it.

Ground and Conditions in Greenfield

Across the Southern Iowa Drift Plain, the subsoil is a gummy grey clay that water will not move through. Rain perches on it instead of soaking in.

That is why a thin base shows itself fast here. Water sits, the subgrade softens, and a patio or drive edge drops out of level.

The fix is a base that sheds water sideways rather than holding it. Class A roadstone brings crushed limestone with the fines left in, so it binds and compacts into a firm, tight course.

Spring is the other half of it. Clay has to dry before anything gets compacted, and a wet spring pushes base work back several weeks.

Erosion follows the same pattern on steeper ground. Streams cut deep, hillslopes carry rills, and gullies open after heavy rain, which is when rip rap goes in at outlets and banks.

Cold winters bring repeated freeze-thaw, enough to heave gravel drives and lanes every spring. Footing depth is set by the local building official.

Materials for Greenfield Projects

Bedding is where a patio is won or lost. Under pavers and flatwork, the bedding layer takes the level and spreads the load, and it has to stay put while the surface above it locks tight.

Limestone Screenings are the bedding layer for pavers and flagstone. The fines in screenings set hard, hold joints and top a compacted roadstone base.

Washed Sand beds and levels slabs and pavers. It is a clean, free draining grade, so it works where water needs to pass rather than sit.

Mason Sand goes into brick and block mortar, paver joints, play sand and horse arena footing.

Under all of it goes Class A Roadstone, the 3/4 inch crushed limestone base that binds and compacts. It handles drives, parking pads, shed bases and farm lanes.

Where the ground stays wet, Clean Rock takes the water away. It is washed and open graded, so it drains into subdrains, pipe bedding and behind retaining walls.

For a new drive or a soft spot under heavy equipment, 1 Inch Roadstone is the coarser grade, laid under a finer surface course.
