Order Gravel, Stone and Soil in Castalia, IA

Iowa Rock Supply handles gravel and aggregate delivery in Castalia, IA, and the yard hand's first question is always how much you need. Each product page carries a calculator, so you can size the load before you order.

Most ground work in this corner of Winneshiek County starts with Class A roadstone, the crushed limestone base course with the fines left in. Around here the soil is thin over limestone and dolomite, so a pad usually needs fill before it needs anything else.

Delivery to Castalia and the Surrounding Area

You order online. Pick the material, choose a quantity by the ton or by the yard, and set a delivery date at checkout.

A dump truck then tips the load in one pile at your site in Castalia. That covers a driveway, a shed pad or a farm lane, and the same service reaches Ossian, Calmar, Fort Atkinson, Ridgeway and Decorah in Winneshiek County.

Bulk loads are heavy, so it helps to know where the pile is going before the truck arrives. If you are still working out how much material the job takes, the calculator on each product page is the place to start.

Materials for Castalia Projects

Fill and sub-base do the quiet work here. When a pad sits on thin soil over rock, you raise the grade first and build on what you placed, not on what was already there.

For raising grade, filling low ground or backfilling ahead of a roadstone course, order Fill Dirt. Clay fill dirt and sandy fill dirt both work for bulk volume.

On top of that goes Class A Roadstone, the 3/4 inch crushed limestone base course for driveways, parking pads, shed bases and farm lanes. The fines stay in so it binds together.

For a new drive, a soft spot or a lane carrying heavy equipment, 1 Inch Roadstone is the coarser roadstone, laid under a finer surface course.

Where water has to move rather than sit, Clean Rock is washed and open graded. It serves subdrains, drainage tile backfill, pipe bedding, septic rock and backfill behind retaining walls.

Finish a graded area with Top Soil, sold locally as black dirt. It handles lawn repair, grading and bed prep, and it is the last layer after the base is set.

Ground and Conditions in Castalia

The Paleozoic Plateau, the driftless northeast, is thin soil over limestone, dolomite, sandstone and shale, with bedrock shallow on the ridgetops. That is why an under-built base shows up fast: there is little soil to cushion it.

Karst shapes the water here. It disappears into sinkholes, fractures and underground passages instead of running off, and springs run all year.

On steep valley sides, runoff comes down fast after a storm.

That runoff scours drives and lanes and cuts banks on the Upper Iowa, Turkey, Yellow and Maquoketa rivers. An open graded drainage layer and a compacted roadstone base both matter more on a slope than on flat ground.

Steep drives and switchback lanes set the working season. Work fits between the spring thaw and the fall freeze, and frost working into fractured rock and thin soil breaks up surfaces on steep lanes each spring.

Questions About Ordering in Castalia

What is the best base under pavers in Castalia?

Start with a compacted course of Class A roadstone, the crushed limestone base with the fines left in. Bed the pavers themselves in limestone screenings, sold as 3/8 inch minus screenings, which fills joints and gives a fine level surface.

Clean rock is the wrong choice under pavers because it is washed and open graded, so it lets water move through instead of locking up as a base.

Do you supply contractors working in Castalia?

Yes. Contractors and homeowners order the same way: online, with a quantity by the ton or by the yard and a delivery date chosen at checkout.
