Buy Fill Dirt in Diagonal, IA

Iowa Rock Supply brings gravel and aggregate delivery in Diagonal, IA to yards, farm lanes and building sites across Ringgold County. That includes the base course this part of Iowa runs on: Class A roadstone, crushed limestone with the fines left in so it binds and compacts.

The ground here shapes what you order. Old till sits under a windblown loess mantle, and the clay beneath it does not take water.

Materials for Diagonal Projects

Grading and bed prep start with the soil. Screened topsoil, which Iowa yards call black dirt, repairs lawns and builds up beds before seed or sod goes down.

Fill dirt raises low ground and backfills a site before a roadstone course goes on top of it.

For raised beds and vegetable gardens, garden mix is blended richer than plain black dirt. Shredded hardwood mulch holds moisture in beds, tree rings and windbreak plantings through a dry August.

Then come the aggregates. Class A roadstone is the standard base for drives, parking pads, shed bases and farm lanes.

Where a lane carries heavy equipment or a drive is going in new, 1 inch roadstone lays under a finer surface course.

Washed stone and sand finish the work. Limestone screenings bed pavers and flagstone and fill the joints.

Clean rock is washed and open graded, so water moves straight through it, which suits subdrains, pipe bedding and septic rock. Mason sand mixes mortar and joints, and washed sand beds and levels under slabs and pavers.

Ground and Conditions in Diagonal

Spring rain and snowmelt are the drivers here. Ground on the Southern Iowa Drift Plain rolls steeply and drains at the surface, but the clay subsoil will not take water.

It perches, runs off, and leaves drives soft at the bottom of a grade.

That is why a drainage layer matters as much as the surface. Clean rock and washed open graded stone let water pass instead of holding it against a base that then pumps and ruts.

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

Riprap armors a bank, a culvert outlet or a pond edge against that runoff.

Timing matters too. This corner of the state works the longest season in Iowa, but clay soils need to dry before anything is compacted, so a wet spring pushes base work back several weeks.

Plan the fill and grading first, then the roadstone.

What stone should I use for drainage in Diagonal?

Limestone screenings and roadstone hold fines and bind instead, so keep those for bases and bedding. Riprap is the choice where a slope, culvert outlet or pond edge needs armoring against runoff.
