Gravel and Aggregate Delivery in Garnavillo, IA

Gravel and aggregate delivery in Garnavillo, IA runs on the working season. Steep drives and switchback lanes here sit between the spring thaw and the fall freeze, so the fall is when surfaces get topped up.

Iowa Rock Supply delivers Class A roadstone, crushed stone, sand and soil to this part of Clayton County.

Materials for Garnavillo Projects

Grading and bed prep come first on most lots around here, and that means soil and fill before any stone. Thin soil over limestone means a yard often needs raising before it can be planted or paved.

• Top Soil, called screened black dirt or screened topsoil locally, for lawn repair, grading and bed prep. Iowa yards name it after the dark prairie soils the state is known for.
• Garden Soil, also called garden mix, blended richer than plain black dirt for raised beds and vegetable gardens.
• Fill Dirt, or clay fill dirt and sandy fill dirt, for raising grade, filling low ground and backfilling before a roadstone course goes down.
• Class A Roadstone, the standard Iowa base course: crushed limestone with the fines left in, so it binds and compacts under drives, parking pads, shed bases and farm lanes.
• Limestone Screenings, the 3/8 inch minus material, for paver and flagstone bedding, joint filling and a fine top dressing over a compacted roadstone base.

For water rather than weight, clean rock is washed and open graded, so water moves straight through it. It suits subdrains, pipe bedding and backfill behind retaining walls.

Where a loose, free draining surface is wanted on a drive, 3/4 inch clean stone does that job.

Ground and Conditions in Garnavillo

Across the Paleozoic Plateau, the driftless northeast, water does not run off the way it does on flatter ground. It disappears into sinkholes, fractures and underground passages, and springs run year round.

Thin soil over limestone, dolomite, sandstone and shale leaves nowhere for water to sit. Steep valley sides send runoff down fast after a storm.

That runoff scours drives and lanes and cuts banks on the rivers of the region. On ground like this, drainage stone matters as much as base stone.

Shallow bedrock on the ridgetops and patchy loess cover change how a site handles. A yard cut into a slope sheds water toward the low side, so a clean, open graded layer under a surface keeps that water moving instead of pooling.

Cold winters in deep, shaded valleys work frost into fractured rock and thin soil. That breaks up surfaces on steep lanes and drives each spring.

Dubuque publishes a frost depth of 42 inches, and the local building official sets footing depth for your site.

Questions About Ordering in Garnavillo

Can I order material by the ton for delivery in Garnavillo?

What stone should I use for drainage in Garnavillo?

Clean rock is the washed, open graded choice, so water moves straight through it. It works for subdrains, pipe bedding and backfill behind retaining walls.

On the Paleozoic Plateau, the driftless northeast, water drops into fractures and passages rather than running off, so an open graded layer keeps it moving. Washed chips suit finer drainage work.
