Gravel, Stone and Soil for Fremont County, IA
Iowa Rock Supply brings gravel, stone and aggregate delivery in Fremont County, IA. On the hills and the bottoms alike, Class A roadstone is the base the county is built on.
Loess sheds water fast, so a drive that starts with the right crushed limestone stays put. Order online and a dump truck tips the load on site.
Materials Delivered in Fremont County
Order by project. A driveway, a patio, a drain and a garden each want a different stone.
Class A roadstone is the standard Iowa base course.
11, and Class C gravel to Gradation No. 10.
Local engineers and city entrance standards write it as Class A roadstone.
Section 4130 covers revetment stone and gabion stone, and Section 4123 covers modified subbase.
Other grades cover the rest. 3/8" Crushed Stone, sold as washed chips, goes into seal coat aggregate and paver joints.
River Rock and 3/8" Natural Pea Gravel handle decorative beds and walkways.
For soil and fill, Fill Dirt raises grade before a roadstone course goes down, and Washed Sand beds slabs and pavers.
Ground Conditions Across Fremont County
Across the Loess Hills and the Missouri River valley, wind blown silt runs more than 60 feet deep, and 150 to 200 feet in places. It forms a narrow band of steep ridges along the full length of the Missouri valley.
Broad, flat, sandy and silty river bottom lies west of the bluff line. That is two different problems in one zone.
On the hills, a dense network of narrow ravines and steep gullies sheds water fast. On the bottoms, flat ground with a high water table is the constraint, and bottomland drives get built up on rock.
Loess erodes as almost nothing else does. It stands in near vertical faces when dry, cuts deep, steep sided gullies under runoff, and collapses or slides when it gets saturated.
Along the river, bank cutting and flood scour do the rest. That is where riprap earns its place, and where an under-built base fails first.
Hill work waits for the silt to dry, because wet loess will not hold a cut. Bottomland work waits for the spring rise to pass.
Cold winters bring repeated freeze-thaw that heaves drives and loosens the silt faces of cuts and banks as the ground thaws. The local building official sets footing depth.
Delivery Across Fremont County
Order online and pick a quantity by the ton or by the yard. Each product page has a calculator to help size the load, and you choose a delivery date at checkout.
A dump truck tips the load on site in one pile. Bulk delivery reaches Hamburg, Sidney, Tabor, Farragut, Randolph, Riverton, Thurman, Percival and Imogene.
Have the drop spot clear before the truck arrives. On a narrow hill road or a soft bottomland lane, a firm standing area matters.
Choosing the Right Material
Fremont County sits in the Loess Hills and the Missouri River valley, with wind blown silt more than 60 feet deep and broad sandy river bottom. Mills County shares that ground region, so the base and drainage choices are the same there.
Page County and Montgomery County sit on the Southern Iowa Drift Plain instead. Old pre-Illinoian till lies under a windblown loess mantle usually 5 to 30 feet thick, with buried paleosols beneath.
Water will not move through the Yarmouth-Sangamon paleosol, a thick, gummy grey clay that farmers call gumbo. That changes the drainage choice.
A compacted roadstone base still carries the load, but where that clay sits under the ground, a clean open stone drainage layer matters more. Deep loess on the hills calls for slope protection and riprap along cut faces.
The practical split holds either way. Class A roadstone for drives and pads, clean rock for water, riprap for banks, and a finer stone for a walkable surface.
