Fill Dirt Delivery for Washington, IA

Iowa Rock Supply brings gravel and aggregate delivery in Washington, IA. Start with the ground.

Clay subsoil on the Southern Iowa Drift Plain does not take water, so it perches and runs off.

Class A roadstone is the crushed limestone base that answers it. Order online and a truck tips the load at your site.

Materials for Washington Projects

Raising grade and building up pads is the work here. Old till sits under a windblown loess mantle, and low ground stays soft.

Fill goes in first, then a compacted course over it.

For a new building pad or a lawn that needs lifting, Fill Dirt brings the grade up before anything else goes down. Clay fill dirt and sandy fill dirt both work for this.

For a driveway, a parking pad or a farm lane, Class A Roadstone is the standard Iowa base course. It is 3/4 inch crushed limestone with the fines left in, so it binds and compacts.

A coarser 1 Inch Roadstone goes under a finer surface course on a new drive or a soft spot.

For a patio or a walkway, bed the pavers on Limestone Screenings. The 3/8 inch minus fines fill the joints and dress the surface over a compacted roadstone base.

For drainage, use Clean Rock. It is washed and open graded, so water moves straight through it.

Subdrains, pipe bedding and retaining wall backfill all take it.

Ground and Conditions in Washington

Across the Southern Iowa Drift Plain, old pre-Illinoian till sits under a loess mantle. Below it are buried paleosols, including a thick grey clay that water will not move through.

Farmers call working that clay gumbo. It is the reason an under-built base fails here: the subsoil holds water, the water perches, and the bottom of a grade turns soft.

This is also the state's most eroded landscape. Streams cut deep and hillslopes carry rills, so gully and stream bank erosion after heavy rain is why rock goes in on slopes and outlets.

Riprap armors those banks and culvert outlets.

Spring rain on saturated clay is the worst of it. A wet spring pushes base work back several weeks, because clay needs to dry before anything gets compacted.

Winters bring repeated freeze-thaw, enough to heave gravel drives and lanes every spring. Frost depth is commonly 42 inches across this ground region, and the local building official sets footing depth.

Questions from Washington Buyers

What is the best base under pavers in Washington?

Bed the pavers on limestone screenings over a compacted Class A roadstone base. The roadstone is 3/4 inch crushed limestone with the fines left in, so it binds and compacts into a firm layer.

Screenings then give you a fine, level bed and fill the joints. Where the clay subsoil perches water, put clean rock in a drainage layer so moisture can move.

Do you supply contractors working in Washington?

Yes. Iowa Rock Supply sells bulk gravel, crushed stone, sand, topsoil and aggregates with delivery across Washington and Washington County.

Builders, excavators and landscapers order the same way a homeowner does: online, by the ton or by the yard, with a delivery date picked at checkout. A dump truck tips the load in one pile at the site.
