Bulk Gravel Delivery to Armstrong, IA

Iowa Rock Supply handles gravel and aggregate delivery in Armstrong, IA, with bulk loads dropped at your site. Class A roadstone leads the list for drives, pads and farm lanes here.

Spring sets the schedule. Across the Des Moines Lobe the ground is tiled and flat, and it sheds water slowly once the frost lets go.

Base work and paver work wait for that window.

Ground and Conditions in Armstrong

This part of Emmet County sits on the Des Moines Lobe, the youngest glacial ground in Iowa. The soil is thick, compact pebbly loam till, and it stays soft well into spring.

A thin base fails fast on this ground. Water collects under a paver patio or a slab and the surface rocks and settles.

The fix is more base before the surface goes down.

Drainage is the second half of it. Much of the ground only drains because it is tiled, and snowmelt sits where the soil below is still frozen.

A clean, open graded layer under flatwork gives that water somewhere to go.

Compaction waits for the frost to come out and the flat ground to shed its spring water. A wet spring shortens the season, and base and paver work runs from late spring to the fall freeze.

Materials for Armstrong Projects

Bedding under pavers and flatwork is where the wrong material shows up first. The bedding layer has to sit on a compacted base, level and uniform, and it has to hold the surface above it.

Class A roadstone is the standard Iowa base course: crushed limestone with the fines left in, so it binds and compacts. Use it under driveways, parking pads, shed bases, farm lanes and the base course beneath a patio.

See Class A Roadstone.

Limestone screenings are the bedding material. These are the fines, sold as screenings or 3/8 inch minus screenings, and they bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base.

See Limestone Screenings.

Washed sand is the other bedding choice, for leveling under slabs and pavers where a clean, free draining grade is wanted. It also works as sand fill.

See Washed Sand.

Mason sand goes into brick and block mortar, paver joints, play areas and horse arena footing. See Mason Sand.

Where water needs to move, clean rock is washed and open graded, so it drains straight through. It backfills subdrains, drainage tile, pipe bedding and retaining walls.

Questions Armstrong Buyers Ask

What gravel is best for a driveway in Armstrong?

Class A roadstone is the Iowa base course for a driveway, a crushed limestone with the fines left in so it binds and compacts. On the Des Moines Lobe, where the till holds water and the ground stays soft in spring, that compacted base is what keeps the drive from rutting.

Top it with driveway rock when an existing surface has thinned out.
