Materials for Walnut Projects

Class A roadstone is the base course for drives, parking pads, shed bases and farm lanes. It is crushed limestone with the fines left in, so it binds and compacts.

One inch roadstone is the coarser grade, laid under a finer surface course on a new drive or a lane that carries heavy equipment.

Driveway rock tops an existing drive or lane that has thinned out, over a compacted roadstone base. Walkway gravel gives garden paths a finer, walkable surface than drive rock.

Washed stone moves water instead of holding it. Clean rock is washed and open graded, so water passes straight through, which suits subdrains, drainage tile backfill, pipe bedding and septic rock.

Limestone screenings bed pavers and flagstone and fill joints. Washed chips serve seal coat aggregate and fine drainage.

Sand and soil cover the finish work. Washed sand beds and levels under slabs and pavers.

Mason sand goes into brick and block mortar and paver joints. Screened topsoil, which Iowa yards call black dirt, handles lawn repair, grading and bed prep.

Fill dirt raises grade and backfills before a roadstone course goes down.

Decorative stone finishes beds and borders. River rock and large river rock build dry creek beds, and Natural Pea Gravel suits walkways and play areas.

Ground and Conditions in Walnut

Across the Loess Hills and the Missouri River valley, water is the constraint, and it arrives in two different ways. On the hills, a dense network of narrow ravines and steep gullies sheds runoff fast.

On the bottoms, flat ground with a high water table and river flooding is the limit, which is why bottomland drives get built up on rock.

Loess erodes as almost nothing else does. It stands in near vertical faces when dry, cuts deep, steep sided gullies under runoff, and collapses or slides once it is saturated.

Along the river, bank cutting and flood scour do the rest.

That shapes what you put down. A drive on the hills needs a base that sheds water and holds its shape, and a clean, open graded stone is the drainage layer that lets water move.

A drive on the bottoms starts with fill dirt to raise grade, then a compacted roadstone course over it.

Cold winters bring repeated freeze and thaw that heaves drives and loosens the silt faces of cuts and banks as the ground thaws. In this part of the state, frost depth is commonly 42 inches, and the local building official sets footing depth.
