Gravel, Stone and Soil for Knox County, IN

Winter and spring are the high-water months on the river bottoms, so low sites in Knox County build best from late spring through fall. For gravel, stone and aggregate delivery in Knox County, IN, that timing matters more than anything else. Indiana Rock Supply stocks #53 stone, the dense graded base that packs hard under drives and slabs, along with washed stone, sand and soil, all sold in bulk.

Materials Delivered in Knox County

#53 stone is the base most Knox County work starts with. It is a dense graded crushed limestone with fines, and Indiana specifies it by size number in Section 904 of the Standard Specifications as compacted aggregate No. 53. Order it for driveways, parking pads, shed bases and the base under pavers and slabs.

Around it sit the other families you will need on the same job. Here are the ones ordered most in this county.

Washed stone covers the drainage side. #57 Stone and #67 Stone handle drainage and concrete aggregate, while 3/4 inch crushed stone goes into drainage beds and construction entrances. For stream bank, ditch and culvert outlet armoring along the Wabash and White rivers, order RipRap, graded locally as revetment, Class 1 and Class 2.

Sand and soil finish the list. Mason Sand serves brick and block work and paver joints. Washed Sand levels and beds under slabs. Top Soil rebuilds lawns and beds over heavy clay or thin rocky ground, and Shredded Mulch holds moisture through hot, humid summers.

Ground Conditions Across Knox County

Start with water and where it goes. Low valley bottoms and old lake-bed flats drain slowly and flood when the Wabash, White, Patoka or Ohio rivers run high. On those sites, a drainage layer of clean stone matters as much as the base itself.

Upland ground brings a different problem. Many loess soils here have a fragipan that holds water near the surface in wet seasons, so a compacted #53 base can sit over soft ground. Strip the silt, then build depth in lifts and compact each one.

Bare loess washes away quickly once its cover is stripped, and river and ditch banks cut during floods. Rip rap on those banks slows the loss. In places, old underground coal mines can also cause the ground to settle.

Winters here are milder than in northern Indiana but still bring repeated freeze-thaw that heaves gravel drives and softens wet, silty subgrades. Frost depth is shallower than in northern Indiana, and the exact footing depth is set by the county or city building department. Do not assume a northern figure.

Delivery Across Knox County

Bulk material arrives by the truckload and is dumped where you point it. Before the drop, clear the route, mark any low wires or soft edges, and pick a spot that keeps the pile out of the way of your equipment.

Order online and size the load by the ton or by the cubic yard, whichever your supplier quotes. Tons measure weight, yards measure volume, and the two do not convert evenly across materials because sand, soil and stone differ in density. Enter the area of the job in the calculator to match the quantity to the material.

We cover Vincennes, Bicknell, Monroe City, Oaktown, Bruceville, Wheatland, Sandborn, Edwardsport, Decker and Ragsdale. Spread the pile near the work and stage it so you are not moving stone twice.

Choosing the Right Material

Ground shifts as you cross county lines, and the material choice shifts with it. Daviess County and Gibson County share Knox County's ground zone, the broad river valleys, old lake-bed flats and loess hills of the Southwest Wabash and Ohio lowlands. The ground is similar, so the comparison there is about projects rather than soil. Expect the same #53 base and the same drainage stone on drives and pads.

Greene County spans more than one zone, taking in the Southwest Wabash and Ohio lowlands plus south-central hills and karst country. Where that ground turns hilly and karst, drainage moves faster and slopes shed water instead of holding it, so rip rap and clean drainage stone carry more of the work than a deep compacted base.
