Materials for Dorchester Projects

Base and driveway surfacing is where a project here starts. Class A roadstone is crushed limestone with the fines left in, so it binds and compacts under a drive, a parking pad, a shed base or a farm lane.

Where a drive is new, or a lane carries heavy equipment, 1 inch roadstone goes down first as the coarser grade. 1 Inch Roadstone has the same fines, just a larger stone.

To top an existing drive that has thinned out, Driveway Gravel lays over a compacted roadstone base. Walkway Gravel gives garden paths a finer, walkable surface than drive rock.

Washed stone is the other family to know. Clean rock is washed and open graded, so water moves straight through it.

Use it for subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

Limestone Screenings are the fines, and they bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base.

Sand and soil round out a site. Washed sand beds and levels under slabs and pavers, mason sand mixes into brick and block mortar, and black dirt, the local name for screened topsoil, repairs lawns and preps beds.

For decorative work, river rock and large river rock build dry creek beds and borders, and Natural Pea Gravel suits walkways and patio bedding.

Ground and Conditions in Dorchester

Across the Paleozoic Plateau, the driftless northeast, water does not run off the way it does on flatter ground. It disappears into sinkholes, fractures and underground passages, and springs run all year.

Thin soil over limestone, dolomite, sandstone and shale leaves nowhere for water to sit. On steep valley sides, runoff comes down fast after a storm and scours drives and lanes.

That is why a fines-bearing base like Class A roadstone earns its place here. It compacts into a surface that sheds water instead of letting it cut underneath.

Where water needs to leave, clean rock gives it an open path.

Bank cutting on the Upper Iowa, Turkey, Yellow and Maquoketa rivers is a regional concern, and riprap armors stream banks, culvert outlets and pond edges against spring runoff.

Frost works into fractured rock and thin soil and breaks up surfaces on steep lanes each spring. Dubuque publishes a frost depth of 42 inches, and the local building official sets footing depth.

Winter access on grades is why surfaces get topped up in the fall.
