Materials for Oto Projects

Fill and sub-base do the heavy lifting on this ground. Bottomland lots sit low and wet, so pads and drives get built up before anything goes on top.

Fill Dirt raises grade, fills low ground and backfills ahead of a roadstone course. It comes as clay fill dirt or sandy fill dirt depending on what the site needs.

On top of that goes Class A Roadstone, the 3/4 inch crushed limestone base with the fines left in. It binds and compacts under driveways, parking pads, shed bases and farm lanes.

For a new drive or a lane carrying heavy equipment, start with 1 Inch Roadstone. This coarser grade goes under a finer surface course and bridges soft spots.

Where water has to move, use Clean Rock. It is washed and open graded, so it works for subdrains, pipe bedding, septic rock and backfill behind retaining walls.

Finish the surface with Driveway Gravel. It tops an existing drive or lane that has thinned out, over a compacted roadstone base.

Ground and Conditions in Oto

This part of the state sits on wind blown silt more than 60 feet deep, and 150 to 200 feet in places. It forms a narrow band of steep ridges along the Missouri valley.

West of the bluff line the ground flattens into sandy and silty river bottom. That bottom ground carries a high water table, and the river floods it.

Loess erodes like almost nothing else. It stands in near vertical faces when dry, cuts deep gullies under runoff, and slides once it is saturated.

An under-built base shows up fast on that ground. Water gets under the fill, the silt moves, and the surface above it drops.

Hill work waits for the silt to dry, because wet loess will not hold a cut. Bottomland work waits for the spring rise to pass.

Cold winters bring repeated freeze and thaw that heaves drives and loosens the silt faces of cuts and banks. Frost depth is commonly 42 inches, and the local building official sets footing depth.

Questions About Material in Oto

What is the best base under pavers in Oto?

Class A roadstone is the base to start with. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts into a firm layer.

Bed the pavers themselves on limestone screenings, which are the 3/8 inch minus fines that level and fill the joints.
