River Rock and Bulk Aggregates for Kokomo, IN

If you need gravel and aggregate delivery in Kokomo, IN, the ground under your job decides what you should order. Most of Howard County sits on dense glacial till, a loamy clay that drains slowly and stays soft after a wet spring. Indiana Rock Supply sells #53 stone and the washed stone grades that handle that water, all in bulk, delivered by the ton.

Because the clay sheds water so poorly, a base that is too thin will rut the first time the ground thaws. The fix is usually a deeper lift of #53 stone, a dense graded material with fines that packs hard once it is compacted.

Materials for Kokomo Projects

Drainage is a common reason to order stone in Kokomo. Late winter and spring rain sits on flat, poorly drained till with no easy outlet, so a lot of this work is about moving water away from a building, a drive, or a low corner of the yard before it becomes a problem.

Washed stone is the core of that work. These grades are screened clean of fines, so water passes straight through instead of pooling. A French drain packed with clean stone and wrapped in fabric carries roof and surface water to a drywell or a daylight outlet, and a downspout run does the same job on a smaller scale.

Size matters more than most people expect. Here is how the grades we deliver break down, coarsest to finest.

For the base and the drive itself, #53 stone is the standard Indiana material. It goes under pavers, slabs, shed bases and parking pads, and it is what we send when a job needs a base that will not shift. If you want a tighter surface on an existing drive, #73 stone packs smoother on top. Driveway stone and Driveway Gravel cover both topping and resurfacing.

Away from the drainage work, Stone Screenings bed and level pavers and flagstone, and River Rock and Large River Rock finish dry creek beds and borders. Both are decorative, but a dry creek bed built over clay still needs the water to have somewhere to go.

Ground and Conditions in Kokomo

Central Indiana sits on a flat to gently rolling plain of dense glacial till. Across Howard County that means loamy clay that holds water, and toward the northeast the clay gets heavier still. Sand and gravel outwash runs along the larger river valleys, but most yards here are clay.

That clay is why base depth is the question we get asked most. A thin layer of #53 stone over wet clay will pump and rut under a loaded truck, so excavate enough to get a compacted lift that sheds water rather than trapping it. Where the subgrade stays wet, a drainage layer of clean stone below the base is worth the extra material.

Timing follows the ground. Base and driveway work runs best from late spring, once saturated clay dries out, through fall. Frozen ground stops compaction through the winter months, and the repeated freeze-thaw heaves and ruts gravel drives on wet clay and softens the subgrade every spring. Frost depth runs about 30 inches in the Indianapolis area, and the local building department sets the figure for your job, with deeper requirements possible toward the north.

Ditch and stream banks scour after heavy rain on this flat ground, and the steeper valley walls slump and wash. Rip rap and large river rock armor those banks and culvert outlets, and a stone that locks together holds a slope that loose material will not.

Delivery to Kokomo and the Surrounding Area

We deliver bulk aggregate across Kokomo and Howard County, including Greentown and Russiaville. Order online, pick your material and quantity, and choose a delivery date at checkout. Quantity is usually figured by the ton or by the cubic yard, so have your length, width and planned depth ready for the calculator to convert.

Lead time depends on the material and the season. Bulk loads run heavier and slower in a wet spring, and a specialty grade may need to be scheduled around the standard base stone. Placing the order before the ground dries out is the surest way to have material on site when the crew is ready.

Delivery is a dump truck that needs a clear approach and room to spread or tailgate the load. Tell us where the pile should land, and we will keep it off finished surfaces and away from anything the truck cannot cross.
