Monroe County, IA Gravel and Landscape Rock Delivery

Iowa Rock Supply handles gravel, stone and aggregate delivery in Monroe County, IA for contractors and homeowners alike. Some buyers are building a farm lane from scratch, and some are topping a drive that has thinned out.

Class A roadstone is the base course most of that work starts from. It is crushed limestone with the fines left in, so it binds and compacts under a vehicle.

Ground Conditions Across Monroe County

Across the Southern Iowa Drift Plain, old pre-Illinoian till sits under a windblown loess mantle. The Yarmouth-Sangamon paleosol beneath it is a thick, gummy grey clay that water will not move through.

That clay is the whole story for a drive or a pad. Rain and spring snowmelt drain at the surface but perch on the clay instead of soaking away, and the bottom of a grade goes soft first.

This is also 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.

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

Freeze and thaw heaves gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.

Materials Delivered in Monroe County

Materials arrive in bulk, and each one suits a different job on the ground described above.

That section defines Class A and Class B crushed stone to Gradation No.

11 and Class C gravel to Gradation No. 10.

County engineers and city entrance standards call the same material roadstone and write it as Class A roadstone. Section 4130 covers revetment stone, erosion stone and gabion stone by class letter, and Section 4123 covers modified subbase.

Washed stone is a separate family. 3/4" Crushed Stone gives a loose, free draining surface, and 3/8" Crushed Stone is sold in Iowa as washed chips for seal coat and paver joints.

Sand and soil round out the order. Washed Sand beds and levels under slabs and pavers, and Mason Sand goes into brick and block mortar.

Garden Soil is blended richer than plain black dirt for raised beds.

Delivery Across Monroe County

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator to help size the load.

A dump truck then tips the load on site in one pile. Have the drop spot clear and reachable, with room for the truck to pull away.

Delivery covers Albia, Lovilia and Melrose along with the rest of the county. Rural addresses and farm lanes are part of the run.

Choosing the Right Material

Wapello County, Marion County and Mahaska County all sit on the same Southern Iowa Drift Plain ground as Monroe County. Old pre-Illinoian till under loess, with the same gummy grey clay beneath, so the base and drainage choices do not change across the line.

On that ground, the choice comes down to what the surface has to do. A drive or pad that needs to bind and compact takes Class A roadstone.

Ground that stays wet and needs water to leave takes clean rock.

Slopes and outlets that take moving water take riprap. Beds and borders that only need to look right take river rock or black dirt.
