Materials for Oskaloosa Projects

Drainage is the job washed stone does around here. Water that perches on clay subsoil has to go somewhere, so clean, open graded stone gives it a path down and away instead of a puddle at the bottom of the grade.

For a French drain, a drywell or a downspout run, you want stone with the fines washed out of it. Water moves straight through open voids rather than sitting in the pile.

• Clean Rock for subdrains, drainage tile backfill, pipe bedding and septic rock. Sold as 1 inch clean or 1 1/2 inch clean.
• 3/4" Crushed Stone for downspout runs, trench backfill and drive surfacing where a loose, free draining stone is wanted.
• 3/8" Crushed Stone, which Iowa quarries sell as washed chips, for fine drainage, paver joints and a thin top dressing.

The base course is a different animal. Class A roadstone is crushed limestone with the fines left in, so it binds and compacts.

It goes down for driveways, parking pads, shed bases and farm lanes.

1 inch roadstone is the coarser grade. Use it under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

Finer material rounds out the list. Limestone screenings bed pavers and flagstone and fill joints.

River rock and large river rock build dry creek beds, borders and splash pads.

Have the drop spot clear and reachable before the truck rolls in. Once the pile is down it stays where it lands, so pick the spot you want it in.

Ground and Conditions in Oskaloosa

This part of Iowa sits on the Southern Iowa Drift Plain, where old till lies under a windblown loess mantle. Beneath that is a thick, gummy grey clay that water will not move through, the layer farmers call gumbo.

Ground like that drains at the surface and then perches. On rolling ground the water runs off and leaves drives soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.

This is also the state's most eroded landscape. Streams cut deep, hillslopes carry a fine texture of rills, and gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and at outlets.

Timing matters as much as material. Southern Iowa gets the longest working season in the state, but clay soils need to dry before anything gets compacted, so a wet spring pushes base work back several weeks.

Plan the delivery around that window.

Winters bring repeated freeze and thaw, which heaves gravel drives and lanes every spring. Frost depth in this part of the state is commonly 42 inches, and the local building official sets footing depth.

What gravel is best for a driveway in Oskaloosa?

Class A roadstone is the standard base for a driveway here, because the fines in it bind and compact over the clay subsoil this area is known for. On a new drive or a soft spot, 1 inch roadstone goes down first as a coarser layer under a finer surface course.

If you want a loose, free draining surface instead, 3/4 inch clean stone works for that. Each product page has a calculator to size the load.
