Gravel and Aggregate Delivery in Crawfordsville, IA

Gravel and aggregate delivery in Crawfordsville, IA runs on the longest working season in the state, but the ground sets the schedule. On the Southern Iowa Drift Plain, clay soils need to dry before anything gets compacted, so a wet spring pushes grading and base work back several weeks.

Iowa Rock Supply delivers Class A roadstone, soil, sand and stone across Washington County.

Materials for Crawfordsville Projects

Soil work comes first on most sites around Crawfordsville. Raising a low yard, shaping a grade or prepping a bed means moving dirt before any stone goes down.

Top Soil, which Iowa yards call screened black dirt or black dirt, covers lawn repair, grading and bed prep. It is the dark prairie soil the state is known for, screened so it spreads and seeds cleanly.

Garden Soil is a richer blend for raised beds, vegetable gardens and planting areas, worked in where plain black dirt is too lean.

Fill Dirt raises grade, fills low ground and backfills ahead of a roadstone course. It goes in first and gets covered.

Once the grade is set, the base course takes over. Class A Roadstone is the standard Iowa base: 3/4 inch crushed limestone with the fines left in, so it binds and compacts under driveways, parking pads, shed bases and farm lanes.

1 Inch Roadstone is the coarser grade. Use it on a new drive, a soft spot or a lane that carries heavy equipment, laid under a finer surface course.

For water that has to move, Clean Rock is washed and open graded, so it drains freely in subdrains, drainage tile backfill, pipe bedding, septic rock and behind retaining walls.

Ground and Conditions in Crawfordsville

Water drives everything here. Spring rain and snowmelt land on ground that drains at the surface but not below it, because the clay subsoil underneath will not take water.

So the water perches, runs off and leaves drives soft at the bottom of a grade. The Yarmouth-Sangamon paleosol, a thick gummy grey clay that farmers across the Southern Iowa Drift Plain call gumbo, is the layer at fault.

That is why a base course has to be built to shed water, and why a clean open stone belongs at the wet end of a drive. A fines-bearing roadstone holds up on a dry pad; where water sits, it needs somewhere to go.

This is also the most eroded landscape in Iowa. Streams cut deeply and hillslopes carry a fine texture of rills, so gully and stream bank erosion after heavy rain is the main reason riprap and clean stone go in on slopes and culvert outlets.

Cold winters bring repeated freeze-thaw, milder than the north but still enough to heave gravel drives and lanes every spring. Southern Iowa frost depth is commonly 42 inches, and the local building official sets footing depth.
