Materials for Algona Projects

Raising grade is the job that comes first on a lot here. Fill dirt goes down to bring low ground up to level before anything else is built on top of it.

Fill dirt is clay or sandy fill used to raise grade, fill low spots and backfill around a foundation. It is a base for the base, not a surface.

Once the grade is set, Class A roadstone is the layer that carries the load. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts into a firm base for a driveway, a parking pad, a shed base or a farm lane.

For a new drive or a lane that carries heavy equipment, 1 inch roadstone is the coarser grade. It goes down under a finer surface course and handles a soft spot better than a fine material will.

Washed sand is a clean, free draining sand used for bedding and leveling under slabs and pavers. It also works as sand fill where you want a clean grade that lets water move.

On top of a compacted roadstone base, limestone screenings bed pavers and flagstone and fill the joints between them.

Ground and Conditions in Algona

Across the Des Moines Lobe the ground is young glacial till, 45 to 60 feet of compact pebbly loam. It is heavy, it holds moisture, and it does not drain on its own the way sand does.

This is pothole country. Kettles and closed depressions hold water, and most of the ground only drains because it is tiled.

Where the ground below is still frozen, snowmelt and spring rain sit on the surface.

That matters under a pad. A base laid on ground that stays wet will pump and shift, so the fill and sub-base have to be built to shed water rather than trap it.

Erosion here is less about slope and more about concentrated runoff. Ditch and tile outlet scour, bank cutting on the larger rivers, and washouts where water gathers on the moraine ridges are the patterns to watch.

Timing is tight. Compaction waits for frost to leave the ground and for 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.

Winters are long and cold, and repeated freeze-thaw heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth is commonly 42 inches in this part of Iowa, and the local building official sets footing depth.

Questions About Ordering in Algona

What is the best base under pavers in Algona?

Class A roadstone is the base course to start with, because it is crushed limestone with the fines left in and it compacts into a firm, bound layer. Over that, limestone screenings bed the pavers and fill the joints.

On ground that stays wet, washed sand is used for leveling because it drains freely and will not hold water under the slab.
