Mason Sand for Patios in Kimballton, IA

Iowa Rock Supply handles gravel and aggregate delivery in Kimballton, IA for contractors and homeowners alike. Some jobs here are a new drive or a farm lane, and some are a patio, a walkway or a shed pad.

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

This is the Southern Iowa Drift Plain, where old till sits under a windblown loess mantle. That ground shapes what you order and when you can work it.

Ground and Conditions in Kimballton

Across the Southern Iowa Drift Plain, a thin base is the failure you notice first. The ground is steeply rolling, so it sheds surface water quickly.

Underneath, a thick grey clay subsoil will not take that water, so it perches and runs off instead.

That runoff leaves drives soft at the bottom of a grade. Spring rain on saturated clay is the worst of it, and a base that was never thick enough to bridge the soft spot starts to rut and pump.

The fix is a properly graded, compacted roadstone base that carries the load above the soft layer. Clay soils also need to dry before anything gets compacted, so a wet spring can push base work back several weeks.

This is Iowa's most eroded landscape, and gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and outlets.

Materials for Kimballton Projects

Bedding under pavers and flatwork is where the material choice shows up in the finished surface. A paver patio or a flagstone walk sits on a bed of limestone screenings, the 3/8 inch minus fines that level and lock the units in place.

Under that bedding, the structural layer is Class A Roadstone, the 3/4 inch crushed limestone base course with the fines left in so it binds and compacts. It carries driveways, parking pads and shed bases across Audubon County.

Where a new drive or a lane that carries heavy equipment needs a coarser start, 1 Inch Roadstone goes in first, under a finer surface course. For drainage, Clean Rock is washed and open graded, so water moves straight through it.

Sand and soil round out a flatwork job. Mason Sand beds brick and block mortar and paver joints, and Washed Sand levels under slabs and pavers.
