Bulk Material Delivery in Dunlap, IA

Iowa Rock Supply handles gravel and aggregate delivery in Dunlap, IA, and Class A roadstone is the base most ground here gets built on. It is crushed limestone with the fines left in, so it binds and compacts under a drive, a parking pad or a shed base.

Dunlap sits in Harrison County, on ground that sheds water fast and holds it poorly. That shapes which stone you want and where it goes.

Materials for Dunlap Projects

Washed stone does the drainage work on this ground. Clean rock is washed and open graded, so water moves straight through it instead of sitting against a foundation or a retaining wall.

Use it for French drains, drywells, downspout runs, subdrains and pipe bedding. The 3/4 inch clean stone suits the same jobs where a smaller stone fits the trench.

Above the drainage layer, Class A roadstone builds the base. One inch roadstone is the coarser grade for a new drive, a soft spot or a lane that carries heavy equipment.

Limestone screenings finish the job. They bed pavers and flagstone, fill joints, and top dress a compacted roadstone base.

For decorative work, river rock and large river rock cover beds, borders and dry creek beds. Natural Pea Gravel suits walkways, play areas and patio bedding.

Delivery to Dunlap and the Surrounding Area

You order online and pick your delivery date at checkout. Quantities are ordered by the ton or by the yard, and each product page has a calculator to size the load.

A dump truck tips the load on site in one pile. Coverage runs across Dunlap and the rest of Harrison County, including Missouri Valley, Logan, Woodbine, Mondamin and Persia.

Delivery is for bulk material only. The truck does not spread or place the load, so plan where you want the pile to land before the truck arrives.

Ground and Conditions in Dunlap

Timing matters more than anything else on this ground. Hill work waits for the silt to dry, because wet loess will not hold a cut.

Bottomland work waits for the spring rise to pass.

Both run from the thaw into late fall. Plan a delivery date around that window rather than against it.

Across the Loess Hills and the Missouri River valley, wind blown silt runs more than 60 feet deep in places. It stands in near vertical faces when dry and cuts deep gullies under runoff.

When it saturates, it slides. That is why drainage stone belongs under and beside anything built into a slope here.

Cold winters bring repeated freeze and thaw that heaves drives and loosens the silt faces of cuts and banks. Frost depth is commonly 42 inches in this part of the state, and the local building official sets footing depth.

What gravel is best for a driveway in Dunlap?

Class A roadstone is the standard base for a driveway here. It is crushed limestone with the fines left in, so it binds and compacts.

For a new drive or a lane that carries heavy equipment, start with 1 inch roadstone and finish with a finer course. Where drainage is the concern, clean rock lets water pass through.
