Bulk Gravel Delivery to Harris, IA

If you are planning a driveway, a patio base or a drainage run, you are looking at gravel and aggregate delivery in Harris, IA. Iowa Rock Supply sells bulk material by the ton or the yard and drops it at your site.

Class A roadstone is the crushed limestone base course this part of Iowa builds on, and it is the right starting point for most ground here.

Ground and Conditions in Harris

Osceola County sits on the Northwest Iowa Plains, where older glacial deposits lie under a loess mantle. Across this part of the state the slopes run long and even, and the stream network drains the ground well.

That means the trouble is usually runoff speed rather than standing water. Heavy rain arrives as short, hard events, and silt loess on a long slope rills and gullies quickly.

A thin base shows that first. Water moves under the edge, the surface shifts, and the drive starts to rut and pothole at the same spots every spring.

The fix is a properly graded roadstone course that binds and compacts, so the surface sheds water instead of letting it work underneath. Get the base right and the top dressing lasts.

Winters here are the coldest and most open in the state, with wind driving frost deep and a long frozen season. Frost depth is commonly 42 inches in this region; confirm the local figure with the building official, since northwest Iowa winters run colder than the state average.

Spring thaw heaves gravel surfaces, so a base that drains is what carries you through the freeze and thaw cycle.

Materials for Harris Projects

Fines and screenings do the fine work on paths and walkways. Limestone screenings, also called 3/8 inch minus screenings, are the crushed fines left after washing.

They bed pavers and flagstone, fill joints, and dress the top of a compacted roadstone base.

On a garden path, screenings give you a firm, walkable surface that locks together under foot. Pair them with Walkway Gravel where you want a slightly coarser path surface.

Class A roadstone is the standard base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts. It goes under 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 is the coarser grade. It goes down under a finer surface course.

See 1 Inch Roadstone.

Where water has to move, use clean rock. It is washed and open graded, so water passes straight through.

Subdrains, drainage tile backfill, pipe bedding and retaining wall backfill all take it. Order Clean Rock.

For a loose, free draining drive surface, 3/4 inch clean stone works, and it also beds pipe and backfills trenches. It is sold at 3/4" Crushed Stone.

Riprap, also called Class D or Class E revetment, armors stream banks, culvert outlets, pond edges and slopes against spring runoff. It is available at Riprap.

Questions About Ordering in Harris

What should I have ready when the truck arrives?

Clear the drop spot and make sure the truck can reach it and turn around. Move vehicles, trailers and anything else out of the way.

The driver tips the load in one pile, so pick a spot where that pile can sit without blocking a door, a drain or a lane you still need to use.

What is the best base under pavers in Harris?

Class A roadstone is the base course for paver work here. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts into a firm platform.

Limestone screenings then bed the pavers and fill the joints. That combination handles the long slopes and spring thaw in this part of northwest Iowa.
