Materials for Avoca Projects

Raising grade and building pads is the work this ground asks for. Low spots and soft ground want fill under them before any stone goes down.

Fill Dirt raises grade, fills low ground and backfills ahead of a roadstone course.

Over that fill, Class A Roadstone is the standard Iowa base course, 3/4 inch crushed limestone with the fines left in so it binds and compacts. It carries driveways, parking pads, shed bases and farm lanes.

For a new drive or a lane that carries heavy equipment, 1 Inch Roadstone is the coarser grade, laid under a finer surface course. Driveway Gravel tops an existing drive that has thinned out.

Water is the other half of the job. Clean Rock is washed and open graded, so water moves straight through it.

It suits subdrains, drainage tile backfill, pipe bedding and backfill behind retaining walls.

For a patio or a walkway, Limestone Screenings bed pavers and flagstone, fill joints and dress a compacted roadstone base. Washed Sand beds and levels under slabs and pavers.

Ground and Conditions in Avoca

Across the Loess Hills and the Missouri River valley, wind blown silt runs more than 60 feet deep and far deeper in places. It stands in near vertical faces when dry, then cuts steep sided gullies under runoff and slides when it saturates.

That is why an under-built base fails here.

Two problems sit in one zone. On the hills, narrow ravines shed water fast.

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

Timing follows the ground. 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.

Cold winters bring repeated freeze and thaw that heaves drives and loosens the silt faces of cuts and banks. The frost depth commonly used in this part of Iowa is 42 inches, and the local building official sets footing depth.

Questions About Material in Avoca

What is the best base under pavers in Avoca?

Class A roadstone is the compacted base course under pavers, because the fines left in the crushed limestone let it bind. Limestone Screenings then bed the pavers and fill the joints.

On this ground, the fill and the base both matter, since silt that stays wet will not hold a paver surface level.
