Limestone Screenings for Pathways in Marengo, IA

Order gravel and aggregate delivery in Marengo, IA the easy way: pick your material online, set the quantity by the ton or the yard, and Iowa Rock Supply tips it on your site. Start with Class A roadstone, the crushed limestone base this part of Iowa builds on.

The ground here sits on the Southern Iowa Drift Plain, where a windblown loess mantle covers old till. Clay below holds water and drives go soft at the bottom of a grade.

Ground and Conditions in Marengo

This is Iowa's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and heavy rain keeps working at gullies and banks.

A thin base shows its failure first at the bottom of a slope, where perched water softens the clay and the surface stone starts to rut. The fix is a properly graded roadstone course that binds and compacts instead of floating on the clay.

Spring is the hard season. Saturated clay needs to dry before anything gets compacted, so a wet spring pushes base work back several weeks.

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

Materials for Marengo Projects

Fines and screenings do the fine work around a yard. Limestone screenings, also called 3/8 inch minus screenings, are the crushed fines left after stone is washed.

Use Limestone Screenings to bed pavers and flagstone, fill the joints between them, and dress the top of a compacted roadstone base. They bind when they are worked in and watered, so a path holds its shape instead of scattering.

For garden paths and walkways that want a finer, walkable surface than drive rock, Walkway Gravel sits well over a screenings bed. It stays tidier underfoot than a coarse stone.

Class A roadstone, also called roadstone or 3/4 inch roadstone, is the standard Iowa base course: crushed limestone with the fines left in so it binds and compacts. It goes under driveways, parking pads, shed bases and farm lanes.

Order it at Class A Roadstone.

Where a new drive, a soft spot or a farm lane carries heavy equipment, 1 inch roadstone is the coarser grade, laid under a finer surface course. Order it at 1 Inch Roadstone.

Water needs somewhere to go. Clean rock is washed and open graded, so it moves water straight through, and it backfills subdrains, drainage tile, pipe beds, septic fields and retaining walls.

Questions About Ordering in Marengo

What should I have ready when the truck arrives?

Have the drop spot cleared and reachable, with no vehicles, trailers or low branches in the way. The driver tips the load in one pile, so pick a spot where that pile will not block a lane, a door or a drain.

Clear the route in as well, because a loaded truck needs room to turn and back.

What is the best base under pavers in Marengo?

Class A roadstone is the base to build on here. It is crushed limestone with the fines left in, so it binds and compacts into a firm platform instead of shifting on the clay.

Bed the pavers on limestone screenings over that base, then work screenings into the joints to lock them.
