Materials for Alleman Projects

Much of the work around Alleman starts below the surface, raising grade and building pads on ground that does not drain well. Fill dirt is the first layer.

Once the grade is where you want it, a compacted roadstone base goes down. Class A roadstone is the crushed limestone with the fines left in, so it binds and compacts under a drive, a parking pad or a shed base.

For a new drive or a lane that carries heavy equipment, 1 inch roadstone is the coarser grade, laid under a finer surface course. Where an existing drive has thinned out, driveway rock tops it over a compacted roadstone base.

• Fill Dirt for raising grade, filling low ground and backfilling before a base course.
• Class A Roadstone for driveways, parking pads, shed bases and farm lanes.
• 1 Inch Roadstone for a new drive, a soft spot or a lane carrying heavy equipment.
• Driveway Gravel for topping an existing drive or lane that has thinned out.
• Top Soil, sold around here as screened black dirt, for lawn repair, grading and bed prep.

For a patio or a walkway, limestone screenings bed pavers and flagstone and fill the joints. Washed sand levels under slabs and pavers, and clean rock handles subdrains, pipe bedding and backfill behind retaining walls.

Ground and Conditions in Alleman

Across the Des Moines Lobe, the ground is young glacial till, 45 to 60 feet deep in places, with sand and gravel along old meltwater channels. This is pothole country, where kettles and closed depressions hold water.

Most of the ground only drains because it is tiled, and snowmelt and spring rain sit on the surface while the ground below is still frozen. That is why an under-built base shows itself here: water collects, the subgrade softens, and the surface rock moves.

Fill and sub-base matter more than the surface layer for that reason. Erosion is less about slope and more about ditch and tile outlet scour and washouts where runoff concentrates.

Compaction waits for the frost to come out and for the 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, 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 Gravel and Stone in Alleman

What is the best base under pavers in Alleman?

Class A roadstone is the base course for pavers, a crushed limestone with the fines left in so it binds and compacts. Limestone screenings go over it to bed the pavers and fill the joints, and washed sand levels under slabs.

On Des Moines Lobe ground, the base is what keeps a patio from shifting when spring water sits under it.
