Bulk Gravel Delivery to Madrid, IA

Order gravel and aggregate delivery in Madrid, IA online, by the ton or by the yard, and Iowa Rock Supply tips it on your site. Start with Class A roadstone, the crushed limestone base course this market builds on.

Madrid sits in Boone County, on the Des Moines Lobe, where thick pebbly loam till and young, poorly drained ground shape what a drive or pad really needs underneath it.

Ground and Conditions in Madrid

Across the Des Moines Lobe, the ground is the youngest glacial till in Iowa. It runs deep and compact, with sand and gravel strung along old meltwater channels and stony, hummocky ground on the moraine ridges.

That ground holds water. Drainage here is young and inefficient, and kettles and closed depressions sit wet until they are tiled.

Snowmelt and spring rain pool on top while the soil below is still frozen.

A thin base shows its weakness fast in that setting. Water reaches the fines, the surface pumps, and ruts open at the field entrance or the end of the lane.

The fix is a properly built base course, not a thicker skin of decorative stone. Class A roadstone carries the fines that bind and compact, so it knits into a surface that sheds traffic instead of swallowing it.

Timing matters too. Compaction waits for frost to leave the ground and for flat ground to shed spring water.

Base and paver work runs from late spring to the fall freeze, and a wet spring shortens that window.

Freeze and thaw heaves gravel drives, lanes and field entrances as the ground lets go. Frost depth is commonly 42 inches, and the local building official sets footing depth.

Materials for Madrid Projects

Fines and screenings do the detail work on paths and walkways. Limestone screenings, also called screenings or 3/8 inch minus screenings, bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base.

Use Limestone Screenings where you want a fine, walkable surface that still locks together underfoot. They are the material for garden paths, patio bedding and the finish over a drive that has already been built right.

For the base itself, Class A Roadstone is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in. It goes under driveways, parking pads, shed bases and farm lanes.

Where a new drive or a lane that carries heavy equipment needs a coarser start, 1 Inch Roadstone lays under a finer surface course. It also fills a soft spot before the top stone goes down.

Water has to move somewhere. Clean Rock is washed and open graded, so it drains freely in subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

Round out a path or bed with Walkway Gravel for a finer surface than drive rock, or 3/8" Natural Pea Gravel for walkways, play areas and small drainage runs.
