Mason Sand for Patios in Unionville, IA

Iowa Rock Supply handles gravel and aggregate delivery in Unionville, IA for two kinds of buyers: contractors setting pavers and flatwork, and homeowners building a patio or walk of their own. Both need the same thing underneath, a base that holds.

Class A roadstone is the crushed limestone base course most of that work starts from here.

Unionville sits in Appanoose County on the Southern Iowa Drift Plain, where a loess mantle covers old till and the subsoil does not take water well.

Ground and Conditions in Unionville

Across the Southern Iowa Drift Plain, the ground is a windblown loess cap over old pre-Illinoian till. Beneath that, a thick grey clay paleosol sits like a plug.

Water will not move through it.

That clay is why a thin base shows itself fast. Water perches on the clay, runs off, and leaves a patio or drive soft at the bottom of a grade.

Pavers over a base that gave way start rocking at the edge.

The fix starts with the bedding package, not with the surface. A compacted Class A roadstone base spreads the load, and a level bedding layer above it keeps each unit sitting flat.

This is also Iowa's most eroded landscape. Streams cut deep, hillslopes carry rills, and heavy rain opens gullies, so rock goes in on slopes and at outlets.

Working season runs long here, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks.

Winters bring repeated freeze-thaw that heaves gravel drives and lanes each spring. Frost depth is commonly 42 inches on the Southern Iowa Drift Plain, and the local building official sets footing depth.

Materials for Unionville Projects

Bedding under pavers and flatwork is where the choice of material decides how the finished surface performs. The layers below the units carry the load and move the water.

Base and Bedding

Class A roadstone, also called roadstone or 3/4 inch roadstone, is the standard Iowa base course. It is crushed limestone with the fines left in, so it binds and compacts into a firm platform for a patio, a drive or a shed base.

Limestone Screenings go on top of that base as paver and flagstone bedding. The fine 3/8 inch minus material levels easily and fills joints once the units are set.

Mason Sand is the other bedding option. It works for brick and block mortar, paver joints, play areas and horse arena footing, and it beds flatwork where a fine, even layer is wanted.

Washed Sand is a clean, free draining grade for bedding and leveling under slabs and pavers, and for sand fill where water needs to pass through.

Drainage and Decorative Layers

Where water has to move, Clean Rock is the answer. It is washed and open graded, so it drains freely, and it backfills subdrains, drainage tile and retaining walls.

3/8" Crushed Stone covers paver joints, fine drainage and a thin top dressing. Iowa quarries sell this size as washed chips.

For patios that want a softer finish, 3/8" Natural Pea Gravel suits walkways, patio bedding and small drainage runs.

Delivery to Unionville and the Surrounding Area

You order online and choose a quantity by the ton or by the yard, whichever you work in. Each product page has a calculator if you want to size the load first.

A dump truck then tips your material in one pile at the site. Plan where that pile should sit before the truck arrives, so it is not in the way of the work.

Iowa Rock Supply delivers across Appanoose County, including Centerville, Moulton, Moravia, Mystic and Cincinnati. A delivery date is picked at checkout, and the load comes to your address in Unionville.

Questions About Ordering in Unionville

What gravel is best for a driveway in Unionville?

Start with Class A roadstone as the base course. It is crushed limestone with the fines left in, so it compacts into a firm surface that sheds traffic.

On a new drive or a soft spot, 1 inch roadstone goes underneath as the coarser layer. Driveway Gravel then tops a drive that has thinned out over a compacted base.

How much material will my project need?

Your quantity depends on the area you are covering and the layer you are building, so the calculator on each product page is the place to work it out. Order by the ton or by the yard.

Bring your measurements and let the numbers set the load size.
