Large River Rock and Bulk Aggregates for Atlantic, IA

Iowa Rock Supply brings gravel and aggregate delivery in Atlantic, IA to drives, pads, lanes and building sites. Start with Class A roadstone, the crushed limestone base course this market builds on.

Across the Southern Iowa Drift Plain, water runs off the surface and stalls in the clay below. Stone that moves water matters here as much as stone that carries a load.

Materials for Atlantic Projects

Slope, swale and bank work comes first in this part of Cass County. Coarse, angular stone is what answers moving water, and it goes in before the finer material.

Coarse Stone for Banks, Swales and Outlets

Riprap, also called revetment stone or Class D revetment, armors stream banks, culvert outlets, pond edges and slopes against spring runoff. It is sold by class, and the class describes how the stone is specified.

Railroad ballast is large and angular, for track beds, heavy hard standing and severe drainage. #4 Crushed Stone handles heavy drainage, construction entrances and trench bottoms.

Drainage Stone

Clean Rock, also called clean stone or 1 inch clean, is washed and open graded, so water moves straight through. Use it in subdrains, drainage tile backfill, pipe bedding, septic rock and behind retaining walls.

#57 Stone and #67 Stone cover drainage runs, subdrain backfill and concrete aggregate. Iowa concrete stone gradations are written D57 and D67.

Base and Surface Stone

Class A Roadstone is crushed limestone with the fines left in, so it binds and compacts. It builds driveways, parking pads, shed bases and farm lanes.

1 Inch Roadstone is the coarser grade. Lay it under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

3/4" Crushed Stone surfaces a drive where loose, free draining stone is wanted, and beds pipe and trench backfill. 3/8" Crushed Stone, sold as washed chips, is seal coat aggregate and a thin top dressing.

Limestone Screenings bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Driveway Gravel tops a drive or lane that has thinned out.

Sand, Soil and Decorative Stone

Washed Sand beds and levels under slabs and pavers. Mason Sand mixes brick and block mortar, fills paver joints and beds play areas and arena footing.

Top Soil, called black dirt or screened black dirt here, repairs lawns, grades and preps beds. Fill Dirt raises grade and backfills before a roadstone course goes down.

River Rock and Large River Rock build decorative beds, borders and dry creek beds. 3/8" Natural Pea Gravel suits walkways, play areas and patio bedding.

Ground and Conditions in Atlantic

This is the longest working season in the state, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks.

Old pre-Illinoian till sits under a windblown loess mantle across the Southern Iowa Drift Plain. Below it, a thick gummy grey clay stops water, and the ground perches and runs off instead of draining.

That is why drives go soft at the bottom of a grade, and why spring rain on saturated clay is the worst of it. This is also Iowa's most eroded landscape, with deep-cut streams and gullies after heavy rain.

Cold winters bring repeated freeze-thaw, which heaves gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
