It is crushed limestone with the fines left in, so it binds and compacts.

Materials for Modale Projects

Filling low ground and building up pads is where a lot of work here starts. If a pad or lane sits low, bring the grade up first, then put a compacted base over it.

Here is what to order for each kind of job.

For a new drive or lane: start with Fill Dirt to raise the grade where ground is low. Then lay 1 Inch Roadstone, the coarser grade, over it, and finish with Class A Roadstone as the surface course.

For topping a drive that has thinned out: Driveway Gravel goes over a compacted roadstone base.

For a patio or walkway: Limestone Screenings bed pavers and flagstone and fill the joints. 3/8" Natural Pea Gravel suits walkways and patio bedding.

For drainage: Clean Rock is washed and open graded, so water moves straight through. Use it for subdrains, pipe bedding and backfill behind retaining walls.

Beds and tree rings take Shredded Mulch. Lawn repair and bed prep take Top Soil, which Iowa yards call black dirt.

Ground and Conditions in Modale

The ground across the Loess Hills and the Missouri River valley is wind blown silt, more than 60 feet deep in places. That silt stands in near vertical faces when dry and cuts deep gullies under runoff.

It also collapses or slides once it gets saturated. A base that looks fine in a dry spell can move when water reaches it.

Two drainage problems show up in this zone. On the hills, narrow ravines and steep gullies shed water fast.

On the flat river bottom, a high water table and river flooding are the constraint, which is why bottomland drives get built up on rock.

That is the case for bringing the grade up with fill dirt first and putting a compacted roadstone base over it. Cold winters bring repeated freeze-thaw that heaves drives and loosens the silt faces of cuts as the ground thaws.

Timing matters. 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.

Both run from the thaw into late fall.
