This is pothole country on the Des Moines Lobe, where flat ground sheds spring water slowly. What you put under a patio matters as much as what you set on top of it.

Ground and Conditions in Spirit Lake

Across the Des Moines Lobe, the ground is thick glacial till with old meltwater channels cut through it. Kettles and closed depressions hold water, and much of the ground drains only because it is tiled.

That is the failure a thin base shows here. Water sits, the subgrade softens, and a patio or walk settles out of level within a season or two.

The fix is a base that stays put when the ground below it is wet. Class A roadstone is crushed limestone with the fines left in, so it binds and compacts into a firm, stable layer.

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

Freeze-thaw heaves gravel drives and field entrances as the ground lets go in spring. A compacted roadstone base gives flatwork something that moves far less than bare till.

Materials for Spirit Lake Projects

Bedding under pavers and flatwork is where a project is won or lost. The right bedding holds a paver true and lets water move instead of trapping it.

Mason Sand, also called masonry sand, is the bedding for brick and block mortar, paver joints and play areas. It packs tight and holds a level surface under a patio.

Washed Sand, or washed fill sand, beds and levels under slabs and pavers. It is clean and free draining where you want water to pass through.

Under the bedding, Class A Roadstone is the standard Iowa base course. It goes under drives, parking pads, shed bases and farm lanes, and it compacts into a firm layer.

Limestone Screenings bed pavers and flagstone, fill joints and top dress a compacted roadstone base. They are the fines left after crushing.

Clean Rock, or clean stone, is washed and open graded, so water moves straight through. Use it for subdrains, pipe bedding and backfill behind retaining walls.
