Mason Sand for Patios in Promise City, IA

Iowa Rock Supply sells gravel and aggregate delivery in Promise City, IA to two kinds of buyers: contractors setting flatwork and homeowners building a patio or walk. Both usually start with Class A roadstone, the crushed limestone base course this part of Iowa runs on.

Promise City sits on the Southern Iowa Drift Plain, where a windblown loess mantle covers old till and a gummy grey clay sits below. That ground decides how a patio base goes together.

Ground and Conditions in Promise City

On the Southern Iowa Drift Plain, the subsoil is a thick, gummy grey clay that water will not move through. Rain perches on it, runs off, and leaves low ground soft long after the surface looks dry.

A thin base over that clay is where flatwork fails. The clay holds moisture, the bedding shifts, and pavers rock or settle out of line within a season or two.

The fix is a base that carries load and a bedding layer that stays even.

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

The working season here is the longest in the state, but clay has to dry before anything gets compacted. A wet spring pushes base work back several weeks, and freeze-thaw heaves gravel drives and lanes every spring.

Materials for Promise City Projects

Bedding is where a patio, a walkway or a slab either holds its line or does not. The material under the pavers has to sit flat, stay put and let the base below it do the structural work.

Class A Roadstone is the standard Iowa base course, 3/4 inch crushed limestone with the fines left in so it binds and compacts. It goes under driveways, parking pads, shed bases and farm lanes, and it is the layer a patio base is built on.

Limestone Screenings are the bedding material itself. The 3/8 inch minus fines bed pavers and flagstone, fill joints, and dress the top over a compacted roadstone base.

Mason Sand beds brick and block, fills paver joints, and works as play sand or horse arena footing. It is the finer, more uniform choice when joints and bedding need to come out even.

Washed Sand is a clean, free draining grade for bedding and leveling under slabs and pavers, and for sand fill where you want water to pass.

For drainage beside the work, Clean Rock is washed and open graded, so water moves straight through it. It backfills subdrains, pipe bedding and retaining walls.
