Materials for Dedham Projects

Base and driveway surfacing is where most Dedham ground work begins. Class A roadstone, also called roadstone or 3/4 inch roadstone, is 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, a soft spot or a lane that carries heavy equipment, 1 inch roadstone goes down first as a coarser layer. 1 Inch Roadstone sits under a finer surface course.

Class A Roadstone then finishes the surface.

Where a drive has thinned out, Driveway Gravel tops it over a compacted roadstone base. For garden paths and walkways that want a finer, walkable surface than drive rock, Walkway Gravel is the choice.

Water is the other half of the job. Clean rock, also called clean stone or 1 inch clean, is washed and open graded, so water moves straight through it.

It backfills subdrains and drainage tile, beds pipes, and sits behind retaining walls. Clean Rock is the material for that work.

Limestone screenings, also called 3/8 inch minus screenings, bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Limestone Screenings handle those jobs.

Ground and Conditions in Dedham

Dedham sits on the Southern Iowa Drift Plain, where old till lies under a windblown loess mantle. Below that is the Yarmouth-Sangamon paleosol, a thick grey clay that water will not move through.

Rain and snowmelt soak the surface soil and then stop at the clay. Water perches, runs off, and leaves drives soft at the bottom of a grade.

Spring rain on saturated clay is the worst of it.

This is Iowa'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 culvert outlets.

Riprap armors those spots.

The working season here is the longest in the state, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks.

Cold winters bring repeated freeze-thaw, milder than the north but still enough to heave gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
