Class A Roadstone, Sand and Gravel Delivery in Scott County, IA
Spring snowmelt raises the river and backs water up the tributary mouths, so low ground stays wet long after local rain stops. Iowa Rock Supply delivers gravel, stone and aggregate in Scott County, IA, by the ton.
Start with Class A roadstone. It is the crushed limestone base course with the fines left in, and it binds and compacts under drives, pads and farm lanes.
Ground conditions across Scott County
Across the Mississippi River corridor, the ground runs from sandy terraces to floodplain that barely drains. Sandy ground sheds water fast; low ground holds it.
That split decides what goes under a drive.
Low lying work waits for the spring river crest to pass before any base goes in. Upland work follows the ordinary thaw to fall freeze pattern, and cold winters heave gravel drives each spring.
River bank cutting and flood scour work the banks, and gullies cut the loess covered bluffs above the valley. Riprap armors the steep ground where runoff concentrates.
Frost depth is commonly 42 inches in this part of the state, and the local building official sets footing depth. Order base material through the season that fits the site.

Choosing the right material
Class A roadstone and 1 inch roadstone both carry fines and compact into a base. Choose by how coarse the layer needs to be, not by which is heavier.
Cedar County ground is loamy glacial till planed down by cold-climate erosion, with a thin and patchy loess cover. It differs from the sand, gravel, silt and clay of the river terraces here.
That till carries a residual stone line or pebble band near the surface and large granite and quartzite erratics in the fields, with limestone bedrock shallow along its eastern edge. Expect different digging there than on Scott County terrace ground.
Clinton County and Muscatine County share the same Mississippi River corridor ground as Scott County: terraces, floodplain and loess uplands. The ground is the same, so the base and drainage choice is the same.
On Scott County ground, match the stone to the water. Sandy terraces drain fast, so a compacted roadstone base holds.
Floodplain that barely drains wants an open graded clean stone layer under it.
