Bulk Material Delivery in Alvord, IA

If you need gravel and aggregate delivery in Alvord, IA, the first question is usually which stone holds a slope or a wet swale. Iowa Rock Supply sells bulk material by the ton and delivers it to your site.

Class A roadstone is the crushed limestone base course with the fines left in, and it binds and compacts.

Across the Northwest Iowa Plains, hard rain arrives in short events and water moves fast once it starts. Coarse, open graded stone is what slows that water down and keeps ground in place.

Materials for Alvord Projects

Slope, swale and bank protection starts with size. The coarsest stone takes the energy of moving water, and finer grades handle bedding, joints and surfacing.

Coarse stone for water and banks

Riprap, also called revetment stone, is large angular rock for stream bank armoring, culvert outlets, pond edges and slope protection against spring runoff. It is specified locally as Class D or Class E revetment.

Railroad ballast is another large angular stone, used for track beds, heavy hard standing and severe drainage where water needs to move straight down through the pile.

#4 Crushed Stone, sold around here as 4 stone or 1 1/2 inch clean rock, suits heavy drainage, construction entrances and trench bottoms. It is washed and open graded, so it does not hold water.

Drainage and bedding stone

Clean Rock, also called clean stone or 1 inch clean, goes into subdrains, drainage tile backfill, pipe bedding and septic rock. The fines are washed out, so water passes through instead of pooling.

#57 Stone and #67 Stone work for drainage runs, subdrain backfill and concrete aggregate. Iowa concrete stone gradations are written D57 and D67.

3/8" Crushed Stone, which Iowa quarries sell as washed chips, is a fine drainage stone and a thin top dressing over a compacted base.

Base, bedding and finish grades

Class A Roadstone is the standard Iowa base course, a 3/4 inch crushed limestone with the fines left in so it binds and compacts. It builds driveways, parking pads, shed bases and farm lanes.

1 Inch Roadstone is the coarser roadstone, for a new drive, a soft spot or a lane that carries heavy equipment, laid under a finer surface course.

Limestone Screenings bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Washed Sand levels under slabs and pavers.

Ground and Conditions in Alvord

This is the driest corner of Iowa, with mean annual precipitation under 25 inches, and heavy storms arrive as short, hard events. Silt loess on long slopes rills and gullies quickly under that kind of rain.

The branching stream network across the Northwest Iowa Plains drains this ground well, so the problem is usually runoff speed rather than standing water. Coarse stone at outlets and on banks is what absorbs that speed.

The working season here runs long once frost is out, but drying winds and low rainfall mean new base and new seeding both need water held on them. Timing a delivery around that matters as much as the material itself.

Winters are the coldest and most open in the state, with wind driving frost deep and heaving gravel surfaces during the spring thaw. Frost depth is commonly 42 inches in this part of Iowa, and the local building official sets the footing figure.
