Large River Rock and Bulk Aggregates for Earlville, IA

Iowa Rock Supply handles gravel and aggregate delivery in Earlville, IA, from Class A roadstone for a farm lane to rip rap for a washed bank. Each product page has a calculator, so you can size the load by the ton or by the yard before you order.

This is Iowan Surface ground: loamy glacial till with a thin, patchy loess cover and a pebble band near the surface. Water moves slowly here, so how a load sheds runoff matters as much as what it is made of.

Materials for Earlville Projects

Start coarse when the job is holding a slope, lining a swale or armoring a bank. Big angular stone is what stands up to moving water.

Riprap, also called revetment stone, is the heavy end of the range. It goes on stream banks, culvert outlets, pond edges and slopes that take spring runoff.

Railroad ballast is large, angular and open. It suits track beds, heavy hard standing and places where water needs to move straight down through the stone.

#4 Crushed Stone, sold around Iowa as clean rock by the inch, works for heavy drainage, construction entrances and trench bottoms.

Step down a size and you get stone for drainage runs and backfill. Clean Rock is washed and open graded, so it goes into subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

#57 Stone and #67 Stone are written as D57 and D67 when a gradation is specified. Both handle drainage and concrete aggregate, with #67 the smaller of the two.

For a drive or a pad, the fines need to stay in so the material binds and compacts. Class A Roadstone is the 3/4 inch crushed limestone base course for driveways, parking pads, shed bases and farm lanes.

1 Inch Roadstone is the coarser grade of the same idea. It goes under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

The fine end finishes the job. Limestone Screenings bed pavers and flagstone, fill joints and top dress a compacted roadstone base.

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

Soil and sand round out a load. Top Soil, called black dirt here, handles lawn repair, grading and bed prep, while Mason Sand goes into mortar and paver joints.

Ground and Conditions in Earlville

Work on the Iowan Surface starts once frost is out and the low gradient ground has drained, and runs to the fall freeze. Low spots stay soft well after the uplands are ready, so timing a delivery around that matters.

Drainage networks here are well established but stream gradients are low, so water moves slowly and pockets of old wetland ground still hold it. Limestone aquifers keep rivers running in dry spells and can put groundwater close to the surface.

That slow water does the damage. Sheet wash crosses the long, low slopes, runoff concentrates into gullies, and banks scour after heavy rain and thaw.

Coarse, open graded stone is the practical answer on a slope, a swale or a bank. Clean rock and rip rap let water through instead of letting it push the material downhill.

Northern Iowa winters bring a long frozen season and repeated freeze-thaw that lifts gravel drives, walks and slabs each spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
