Bulk Aggregates for Patios in Winterset, IA

Order gravel and aggregate delivery in Winterset, IA by the ton or the yard. Iowa Rock Supply drops bulk material at your site, from Class A roadstone to bedding sand.

Start with the material under the pavers. Get that layer right and the patio stays flat through every spring thaw this county gets.

Ground and Conditions in Winterset

Winterset sits on the Southern Iowa Drift Plain, where old till lies under a windblown loess mantle. Below both sits a thick grey clay that water will not pass through.

Rain perches on that clay and runs off instead of soaking in. A patio cut into a slope collects that water at the low edge, and the ground there stays soft.

This is the most eroded landscape in Iowa. Streams cut deep, hillslopes carry fine rills, and heavy rain moves bank and gully soil.

Clay has to dry before anything gets compacted on it. A wet spring pushes flatwork back several weeks, so watch the forecast before you schedule.

Freeze and thaw heave gravel and pavement every spring. Frost depth runs about 42 inches on the Southern Iowa Drift Plain, and the local building official sets footing depth.

Materials for Winterset Projects

Bedding is where a patio is won or lost. A thin base over this clay flexes, and the pavers above it rock and settle out of line.

Build the base from Class A Roadstone, the 3/4 inch crushed limestone with the fines left in. Those fines bind and compact, so the layer locks into a firm platform.

Bed the pavers themselves in Limestone Screenings. The 3/8 inch minus grit levels under flagstone and fills the joints between units.

Set a concrete slab or a paver field on Washed Sand. It is clean and free draining, so it beds and levels without holding water under the slab.

Where a patio meets a wall, a downspout or a low corner, water needs somewhere to go. Clean Rock is washed and open graded, so water moves straight through instead of sitting against the house.

For brick and block work around a patio, Mason Sand mixes into mortar and packs into joints.

Questions About Gravel and Aggregate in Winterset

What gravel is best for a driveway in Winterset?

Class A roadstone is the standard base for a Winterset drive. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts into a firm surface.

Top it with driveway rock once the base has firmed up. Where the drive crosses soft clay at the bottom of a grade, 1 inch roadstone goes down first as a coarser layer.

How much material will my project need?

Quantities are ordered by the ton or by the yard, so you can match the load to the job. Each product page carries a calculator that helps you size the load from your own project numbers.

Order the base, bedding and drainage stone as separate quantities if you are building a patio in stages.
