Mason Sand for Patios in Duncombe, IA

Iowa Rock Supply offers gravel and aggregate delivery in Duncombe, IA for patios, drives and drainage work. If you are bedding pavers or leveling flatwork, the load usually starts with a compacted Class A roadstone base and a sand bed on top.

Duncombe sits in Webster County, on the Des Moines Lobe, where thick glacial till and flat, tiled ground shape how a base goes in.

Ground and Conditions in Duncombe

The ground across the Des Moines Lobe is thick, compact pebbly loam till. It holds water, and much of it only drains because it is tiled.

A thin base shows its weakness fast here. Spring freeze-thaw heaves a shallow layer, and the pavers above it rock and drop out of line.

This is pothole country. Kettles and closed depressions hold water, and snowmelt sits on the surface while the ground below is still frozen.

That is why bedding work waits. Compaction needs the frost out and the flat ground to shed its spring water, so base and paver work runs from late spring to the fall freeze.

A wet spring shortens that window, and the deep frozen season means the base has to be built to take the heave when the ground lets go.

Erosion here is less about slope and more about concentrated runoff. Ditch and tile outlet scour and washouts on the moraine ridges are the usual trouble spots.

Materials for Duncombe Projects

Bedding under pavers and flatwork is the job that decides how the finished surface holds up. The bed is only as good as the base under it.

Class A Roadstone is the standard Iowa base course, crushed limestone with the fines left in so it binds and compacts. It carries driveways, parking pads, shed bases and farm lanes, and it is the layer that goes under a sand bed.

Mason Sand is the bedding material for brick and block mortar, paver joints and play areas. It packs smooth and even, which is what a paver bed needs.

Washed Sand is a clean, free draining grade used for bedding and leveling under slabs and pavers. Where water needs to move under flatwork, this is the sand to set.

Limestone Screenings are the fines, used for paver and flagstone bedding, joint filling and a fine top dressing over a compacted roadstone base.

For drainage beside a patio or along a foundation, Clean Rock is washed and open graded, so water moves straight through it.
