Large River Rock and Bulk Aggregates for Lamoni, IA

For gravel and aggregate delivery in Lamoni, IA, Iowa Rock Supply sells bulk material by the ton or by the yard and tips it at your site. Class A roadstone is the base most drives and lanes here are built on.

The ground on the Southern Iowa Drift Plain is rolling, and it sheds water fast until that clay layer stops it. That is why so much of the stone that goes in around here ends up on a slope or at a pipe outlet.

Materials for Lamoni Projects

Coarse stone is the first thing to sort out when water is the problem. Riprap, sold locally as revetment stone and specified as Class D or Class E revetment, armors stream banks, culvert outlets and pond edges.

On this ground, where runoff cuts gullies after heavy rain, that is the material that holds a bank in place.

Below riprap in size, #4 Crushed Stone goes into heavy drainage, construction entrances and trench bottoms. #57 Stone handles subdrain backfill and drainage runs where a smaller open stone fits the trench.

Clean rock, also called clean stone or 1 inch clean, is washed and open graded so water moves straight through it. It suits subdrains, drainage tile backfill, pipe bedding and septic rock, and it is the right backfill behind a retaining wall.

When a drive needs a surface that drains, 3/4" Crushed Stone is the usual pick, and it works as pipe bedding too. 3/8" Crushed Stone, which Iowa quarries sell as washed chips, is the fine end: seal coat aggregate, small drainage runs and paver joints.

For a base, Class A roadstone is 3/4 inch crushed limestone with the fines left in, so it binds and compacts. 1 Inch Roadstone is the coarser grade, laid under a finer surface course on a new drive, a soft spot or a lane carrying heavy equipment.

Limestone screenings bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Washed sand levels under slabs and pavers, and black dirt, which Iowa yards call screened topsoil, repairs lawns and preps beds.

Ground and Conditions in Lamoni

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

Under the windblown loess sits old pre-Illinoian till with a thick grey clay paleosol that water will not move through, and local farmers call working in it gumbo. Rain perches on that layer and runs off, which leaves drives soft at the bottom of a grade and sends water hard at banks and outlets.

Cold winters bring repeated freeze-thaw, enough to heave gravel drives and lanes every spring. Where a footing depth is needed, Decatur County building officials set it.

Questions About Stone in Lamoni

What stone should I use for drainage in Lamoni?

Use clean rock or clean stone where water has to move through the material, such as subdrains, pipe bedding and wall backfill. For a drainage run at a set size, #57 Stone or #67 Stone both work.

Where a bank or an outlet is taking runoff, riprap is the material that holds.

What should I have ready when the truck arrives?

The truck tips your load in one pile, so have a clear spot that a dump truck can reach and turn around in. Keep vehicles and equipment out of the way.

Decide where the pile goes before the truck shows up, because the load is dropped in one place and not moved by the driver.
