Large River Rock, Stone and Soil Delivery in Anthon, IA

Iowa Rock Supply brings gravel and aggregate delivery in Anthon, IA to your driveway, barn lane or building pad. Class A roadstone is the crushed limestone base course this part of Iowa builds on.

Anthon sits in Woodbury County, on ground shaped by deep wind blown silt and the flat, sandy river bottoms west of the bluff line. Both change what a load has to do.

Materials for Anthon Projects

Steep silt ridges and fast gullies put coarse stone first here. Slope, swale and bank protection starts with the largest, most angular rock on the page and works down in size from there.

Riprap, sold locally as revetment stone, is the heavy end of that work. It armors stream banks, culvert outlets, pond edges and steep faces against spring runoff.

#4 Crushed Stone is a smaller angular clean stone for heavy drainage, trench bottoms and construction entrances. Iowa quarries usually sell this size as clean rock by the inch.

Clean Rock, also called clean stone or 1 inch clean, is washed and open graded so water moves straight through it. It backfills subdrains, drainage tile and septic systems.

Class A Roadstone is the 3/4 inch crushed limestone base course with the fines left in, so it binds and compacts. It carries driveways, parking pads, shed bases and farm lanes.

Limestone Screenings are the fine end, used to bed pavers and flagstone and to fill joints over a compacted roadstone base.

For decorative beds and dry creek beds, River Rock is rounded gravel washed out of the Missouri and Mississippi valleys. Large River Rock suits heavier bank and splash work.

Ground and Conditions in Anthon

Timing drives everything on this ground. Hill work waits for the silt to dry, because wet loess will not hold a cut, and bottomland work waits for the spring rise to pass.

Across the Loess Hills and the Missouri River valley, the silt runs more than 60 feet deep in places and erodes as almost nothing else does. It stands in near vertical faces when dry, then cuts steep gullies under runoff and slides when saturated.

That is why coarse, angular stone earns its place on banks, swales and culvert outlets. On the flat bottoms, a high water table and river flooding are the constraint, which is why drives there get built up on rock.

Cold winters bring repeated freeze and thaw that heaves drives and loosens the silt faces of cuts and banks. The local building official sets footing depth.
