Bulk Aggregates for Patios in Swisher, IA

Order gravel and aggregate delivery in Swisher, IA online, by the ton or by the yard, and Iowa Rock Supply tips it on site. Start with Class A roadstone, the crushed limestone base course this part of Iowa builds on.

Swisher sits in Johnson County, on the Southern Iowa Drift Plain, where old till sits under a windblown loess mantle. That ground sets what works under a patio and what does not.

Ground and Conditions in Swisher

Across the Southern Iowa Drift Plain, a thin base course fails the same way every time. The load punches through, the pavers rock, and joints open at the first thaw.

The reason is under the surface. A thick, gummy grey clay paleosol sits beneath the loess, and water will not move through it.

Rain perches on that clay, runs off, and leaves drives and pads soft at the bottom of a grade. Spring rain on saturated clay is the worst of it.

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

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

Clay soils need to dry before anything gets compacted, so a wet spring pushes base work back several weeks.

Materials for Swisher Projects

Bedding is where a patio or walk is won. Get the layer under the pavers right and the surface stays flat.

Class A roadstone is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts. Build the structural layer from Class A Roadstone, then bed the pavers above it.

Limestone screenings, sold as 3/8 inch minus screenings, are the bedding material itself. Use Limestone Screenings to bed pavers and flagstone, fill joints, and dress the top over a compacted roadstone base.

Washed sand beds and levels under slabs and pavers, and works as clean fill where a free draining grade is wanted. Washed Sand is the sand for flatwork.

For a new drive, a soft spot, or a lane carrying heavy equipment, 1 inch roadstone is the coarser grade that goes under a finer surface course. Order 1 Inch Roadstone for that layer.

Where water has to move rather than sit, clean rock is washed and open graded so it drains straight through. Clean Rock backfills subdrains, pipe bedding, and retaining wall backfill.

Round out a bed with River Rock for borders and dry creek beds, or Top Soil, the screened black dirt Iowa yards call for, on lawn repair and bed prep.
