3/4 Inch Clean Stone and Bulk Aggregates for Dexter, IA

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

Dexter sits in Dallas County on the Southern Iowa Drift Plain, where old till and a loess mantle sit over clay that holds water.

Materials for Dexter Projects

Water is the practical problem on Dexter lots. Clay subsoil takes very little, so roof runoff and driveway water have to be carried away before it sits.

Washed stone is the material that does that work, because it is open graded and water moves straight through it.

Start coarse with Clean Rock, sold as clean stone or 1 inch clean. It goes in subdrains, drainage tile backfill, pipe bedding, septic rock and behind retaining walls.

#4 Crushed Stone is heavy drainage and trench bottoms at a larger size. #57 Stone and #67 Stone suit subdrain backfill and drainage runs, and Iowa concrete stone gradations are written D57 and D67.

For a French drain or a downspout run, 3/4" Crushed Stone is a washed, free draining stone that fits pipe bedding and trench backfill. A drywell wants the same open stone, not a fines bearing material.

Finer washed sizes finish the job. 3/8" Crushed Stone, sold as washed chips, covers seal coat aggregate, fine drainage and paver joints.

Where a base is needed, Class A Roadstone is the 3/4 inch crushed limestone base for drives, parking pads, shed bases and farm lanes. 1 Inch Roadstone is the coarser grade for a new drive or a soft spot.

Limestone Screenings bed pavers and flagstone and fill joints.

Delivery to Dexter and the Surrounding Area

Iowa Rock Supply delivers bulk material across Dallas County, including Dexter plus Waukee, West Des Moines, Urbandale, Perry and Adel. You order online, pick your quantity by the ton or by the yard, and choose a delivery date at checkout.

Each product page has a calculator if you want to size the load. A dump truck then tips the material on site as one pile, so it is worth thinking about where that pile lands before the truck arrives.

Sand and soil travel the same way. Washed Sand beds and levels under slabs and pavers, Mason Sand mixes mortar and fills paver joints, and Top Soil, which Iowa yards call black dirt, repairs lawns and preps beds.

River Rock and Large River Rock handle decorative beds and dry creek beds.

Ground and Conditions in Dexter

This part of the Southern Iowa Drift Plain has the longest working season in the state, so a delivery date is usually easy to find. The clay is the catch.

It has to dry before anything gets compacted, and a wet spring pushes base work back several weeks.

The ground is steeply rolling and drains at the surface, but the clay subsoil does not take water. It perches, runs off, and leaves drives soft at the bottom of a grade, which is why a drainage layer matters as much as the surface stone.

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

Riprap, sold as revetment stone, armors stream banks, culvert outlets, pond edges and slopes against spring runoff.

Cold winters bring repeated freeze and thaw, which heaves gravel drives and lanes every spring. Frost depth is commonly 42 inches in this part of Iowa, and the local building official sets footing depth.
