Bulk Gravel and Stone Delivery in Montgomery County, IA
You want gravel, stone and aggregate delivery in Montgomery County, IA, and you want the right material the first time. Iowa Rock Supply sells bulk loads online and delivers them by the ton or by the yard.
Most drive and pad work here starts with Class A roadstone, the crushed limestone base course with the fines left in so it binds and compacts. Order it for a farm lane, a parking pad or a shed base.
Ground Conditions Across Montgomery County
Across the Southern Iowa Drift Plain, the ground is old till under a windblown loess mantle. Clay subsoil does not take water well, so it perches and runs off instead of soaking in.
The practical result is soft ground at the bottom of a grade after spring rain. A compacted roadstone course gives you a surface that stands up to that.
This is also the state's most eroded landscape. Streams cut deep, hillslopes rill, and gully and bank erosion after heavy rain is why rock goes in on slopes and outlets.
The working season here runs long, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks.
Winters bring repeated freeze and thaw, which heaves gravel drives and lanes every spring. Frost depth in this part of Iowa is commonly 42 inches, and the local building official sets footing depth.
Materials Delivered in Montgomery County
Class A roadstone is the standard Iowa base course, and it is the material county engineers and city entrance standards specify for drives, farm lanes and pads.
11 and Class C gravel to Gradation No. 10.
County engineers call it roadstone, and you will see it written as Class A roadstone on plans.
Below the coarse sizes, limestone screenings bed pavers and flagstone, fill joints and top dress a compacted roadstone base. You can order them at Limestone Screenings.
For decorative work, River Rock and Large River Rock cover beds, borders and dry creek beds. Both are rounded gravel washed out of the Missouri and Mississippi valleys.
On the soil side, screened topsoil goes down as black dirt for lawn repair and bed prep. Order Top Soil for grading, or Garden Soil where a richer blend is wanted for raised beds.
Choosing the Right Material
Pottawattamie County, Mills County and Fremont County all sit on the Loess Hills and the Missouri River valley. That ground is windblown silt more than 60 feet deep in places, forming steep ridges along the valley with flat, sandy river bottom beyond the bluff line.
Montgomery County's ground is different. Here you have till under a loess mantle, with a heavy clay subsoil that holds water instead of draining it.
That difference changes the choice. On deep silt the concern is how steep the ground is and how fast water moves off it.
On the clay ground here, water perches, so a clean open graded stone under or beside a base matters more.
Use Clean Rock for subdrains and pipe bedding, and 3/4" Crushed Stone where you want a loose, free draining drive surface. For bank and outlet protection, Riprap is the size to look at.

Questions About Ordering Gravel and Stone
What is the difference between crushed stone and Natural Pea Gravel?
Crushed stone is angular and mechanically broken, so the pieces interlock and hold position under a load. Natural Pea Gravel is rounded and smooth, washed out of river valleys.
In Iowa you will see it sold as 3/8" Natural Pea Gravel for walkways, play areas and patio bedding. Use angular stone where you need it to lock, and rounded gravel where you want a loose decorative surface.
Should I order material by the ton or by the yard?
Either works, and quantities are ordered both ways. The ton is a weight and the yard is a volume, so which one you pick mostly comes down to how you have figured the job.
Each product page has a calculator to help you size the load. You place the order online and choose a delivery date at checkout.
Which stone is best for drainage in Montgomery County?
Clay subsoil here does not take water, so it perches, and you want washed, open graded material that water moves straight through. Clean rock in the 1 inch and 1 1/2 inch sizes is the standard for subdrains, pipe bedding and wall backfill.
3/4" Crushed Stone works for a loose, free draining drive surface.
