Class A Roadstone, Sand and Gravel Delivery in Cedar County, IA
Iowa Rock Supply brings gravel, stone and aggregate delivery in Cedar County, IA. Runoff moves slowly here, so soft ground holds water and an under-built base gives way first.
Start with Class A roadstone, the crushed limestone base with the fines left in. It binds and compacts under drives, pads, shed bases and farm lanes.
Ground Conditions Across Cedar County
Cedar County sits on the Iowan Surface. Loamy glacial till lies under a thin, patchy loess cover, and a pebble band sits near the surface.
Large granite and quartzite erratics turn up in the fields. Limestone bedrock runs shallow along the eastern edge.
Across the Iowan Surface, drainage networks are well established but stream gradients are low. Water moves slowly, and pockets of old wetland ground still hold it.
That slow water is why a base needs the fines left in. Roadstone compacts into a bound layer instead of letting water work underneath.
Sheet wash crosses the long, low slopes, and gullies cut where runoff concentrates. On the Iowan Surface side, spring thaw and heavy rain scour stream banks.
Rip rap answers bank scour and culvert outlets. Work starts once frost is out and the ground has drained, and low spots stay soft well after the uplands are ready.
Materials Delivered in Cedar County
Order by project type. For a driveway, Class A roadstone carries the base and Driveway Gravel tops a lane that has thinned out.
That section defines Class A and Class B crushed stone to Gradation No.
11 and Class C gravel to Gradation No. 10.
County engineers and city entrance standards call the same material roadstone and write it as Class A roadstone. Section 4130 covers revetment stone, erosion stone and gabion stone by class letter, and Section 4123 covers modified subbase.
For sand, Mason Sand sets brick and block mortar and beds paver joints. Washed Sand levels under slabs and pavers.
In soil, Top Soil is what Iowa yards call black dirt, screened for lawn repair, grading and bed prep. Garden Soil is blended richer for raised beds and vegetable gardens.
Choosing the Right Material
Johnson County lies on the Southern Iowa Drift Plain, and its ground is not the same as Cedar County's. Old pre-Illinoian till sits under a windblown loess mantle there.
Beneath that loess is a thick, gummy grey clay that water will not move through. A base there faces trapped water that Cedar County's slow-draining till does not hold the same way.
Scott County and Clinton County both sit on the Mississippi River corridor. Their ground is sand, gravel, silt and clay on river terraces and floodplain, with sandy blow ground on the older terraces and till and loess uplands rising behind the bluff line.
Sandy terrace ground drains freely, so a free draining clean stone does less work there than it does over Cedar County's tighter till.
Match the material to the ground under it. Where water sits, order an open graded stone so it can move.
