Ground and Conditions in Thor

Thor sits in Humboldt County, on the Des Moines Lobe. That ground is young glacial till: thick, compact pebbly loam over sand and gravel left by old meltwater channels.

Pavers fail here when the base under them is too thin. The till holds water, and a shallow base moves with it.

This is pothole country. The drainage network is young and inefficient, and kettles and closed depressions hold water after snowmelt and spring rain.

Most ground around here only drains because it is tiled. Where the ground below is still frozen, meltwater sits on the surface.

Compaction waits for the frost to come out and for flat ground to shed its spring water. Base and paver work runs from late spring to the fall freeze, and a wet spring shortens that window.

Winters are long and cold, with repeated freeze-thaw that heaves gravel drives and field entrances as the ground lets go in spring. Ask the local building official about footing depth for anything structural.

Materials for Thor Projects

Bedding is where a patio in Thor is won or lost. Get the layer under the pavers right and the surface stays flat through the heave season.

Class A Roadstone

Class A roadstone is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts. Use it under driveways, parking pads, shed bases and farm lanes.

Under pavers it carries the load. Lay it as the structural base, then bed the surface on something finer.

Limestone Screenings

Limestone screenings, also called 3/8 inch minus screenings, are the bedding layer. They bed pavers and flagstone, fill joints, and dress the top of a compacted roadstone base.

Washed Sand

Washed sand beds and levels under slabs and pavers. It is a clean, free draining grade, so it works where you want sand fill that lets water move.

Mason Sand

Mason sand, or masonry sand, goes into brick and block mortar and paver joints. It also works as play sand and horse arena footing.

Clean Rock

Clean rock is washed and open graded, so water moves straight through it. Use it for subdrains, drainage tile backfill, pipe bedding, septic rock and backfill behind retaining walls.
