Mason Sand for Patios in Centerville, IA

Iowa Rock Supply handles gravel and aggregate delivery in Centerville, IA, and the working season here is the longest in the state. Clay ground still has to dry before anything gets compacted, so a wet spring pushes base work back several weeks.

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

Order online by the ton or the yard, and a dump truck tips the load on your site.

Ground and Conditions in Centerville

Across the Southern Iowa Drift Plain, old till sits under a windblown loess mantle. Buried in that stack is the Yarmouth-Sangamon paleosol, a thick grey clay that water will not move through.

Ground like that drains at the surface but perches underneath. Runoff collects and leaves drives soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.

This is also the state's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and gully and bank erosion after heavy rain is why rock goes on slopes and at outlets.

A thin base shows its failure first at the edges and at any low spot where water sits. The fix is more base material and a drainage layer that lets water out from under the surface.

Materials for Centerville Projects

Bedding under pavers and flatwork is where a patio is won or lost. The bedding layer has to be fine, uniform and easy to screed, and it has to sit on a base that will not move.

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 under drives, parking pads, shed bases and farm lanes.

Limestone screenings, also called 3/8 inch minus screenings, are the bedding layer itself. Use them to bed pavers and flagstone, fill joints, and dress the surface over a compacted roadstone base.

Mason sand, also called masonry sand, is the other bedding choice. It sets brick and block mortar, fills paver joints, and works as play sand or horse arena footing.

Washed sand, also called concrete sand or washed fill sand, beds and levels under slabs and pavers. It is a clean, free draining grade for sand fill.

1 inch roadstone, also called 1 inch minus, is the coarser grade. It goes under a finer surface course on a new drive, a soft spot, or a lane that carries heavy equipment.

Questions About Material in Centerville

What gravel is best for a driveway in Centerville?

Class A roadstone is the base course for a drive here, because it is crushed limestone with the fines left in and it binds and compacts. On soft ground, 1 inch roadstone goes underneath as the coarser layer.

Top an existing drive that has thinned out with driveway gravel over that compacted base.
