Materials for Truro Projects

Water is the reason most rock goes in around Truro. When it has nowhere to go, it sits.

The fix is open graded stone that lets it through instead of holding it.

Start with Clean Rock for French drains, drywells, downspout runs and septic lines. It is washed and open graded, so water moves straight through it and the trench stays a drain instead of turning into a bucket.

For a driveway that sheds water instead of holding it, 3/4" Crushed Stone and 3/8" Crushed Stone are the washed sizes. Both stay loose and free draining.

The 3/8 inch washed chips also go in paver joints and fine drainage runs.

A base course has to bind, and that means fines. Class A Roadstone is crushed limestone with the fines left in, and it compacts into a firm surface under a drive, a parking pad or a shed base.

1 Inch Roadstone is the coarser grade for a new drive or a soft lane carrying heavy equipment.

At the fine end, Limestone Screenings bed pavers and flagstone and fill joints. Washed Sand levels under slabs and pavers, and Mason Sand mixes into brick and block mortar.

Delivery to Truro and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on your site in one pile.

A drive, a farm lane or a bare lot all work as long as the truck can reach the spot.

Keep the calculator handy when you order. It is the plainest way to line up the right quantity for the job you are doing.

Ground and Conditions in Truro

Across the Southern Iowa Drift Plain the working season runs long, but clay ground has to dry before anything gets compacted. A wet spring pushes base work back several weeks.

The ground under this part of Madison County is old till under a windblown loess mantle. Below it sits a thick grey clay that water will not move through, so it perches and runs off instead of soaking away.

That is why drives go soft at the bottom of a grade in spring. It is also why this is Iowa's most eroded landscape, where streams cut deep and heavy rain carves gullies and stream banks.

Practically, it means drainage goes in before the surface does. Washed stone in a trench or a drywell moves water off the low spots, and a compacted roadstone base on top holds the drive.

Riprap armors a culvert outlet or a bank where runoff concentrates.

Winters bring repeated freeze and thaw, which heaves gravel drives every spring. Frost depth is commonly 42 inches across the Southern Iowa Drift Plain, and the local building official sets footing depth.
