River Rock and Bulk Aggregates for Clermont, IA

Water here does not run off. It drops into sinkholes, fractures and underground passages, and springs run all year.

That shapes gravel and aggregate delivery in Clermont, IA more than anything else. Iowa Rock Supply stocks the washed stone that moves that water, along with Class A roadstone for the drives and lanes above it.

Materials for Clermont Projects

Start with open graded stone. Clean rock is washed and open graded, so water passes straight through it instead of sitting against a foundation or a pipe.

Use Clean Rock for French drains, drywells, downspout runs, subdrains and septic rock. The 1 inch and 1 1/2 inch sizes give the void space those runs need.

For drive surfacing where you want a loose, free draining layer, 3/4" Crushed Stone works, and it beds pipe and trench backfill as well. 3/8" Crushed Stone, sold locally as washed chips, handles seal coat aggregate, paver joints and a thin top dressing.

Below the washed stone, build the base. Class A Roadstone is the Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts under driveways, parking pads, shed bases and farm lanes.

1 Inch Roadstone is the coarser grade for a new drive, a soft spot or a lane that carries heavy equipment, laid under a finer surface course. Where a drive or lane has thinned out, Driveway Gravel tops it over a compacted roadstone base.

Ground and Conditions in Clermont

Across the Paleozoic Plateau, the driftless northeast, soil is thin over limestone, dolomite, sandstone and shale. Bedrock is shallow on the ridgetops and exposed in the valley walls, and the loess cover is patchy.

That leaves nowhere for water to sit. Karst sends it underground through sinkholes and fractures, springs run year round, and steep valley sides push runoff down fast after a storm.

A surface that traps water on a slope scours out.

Plan around the working season. Work fits between the spring thaw and the fall freeze, and steep drives and switchback lanes are the constraint on where a truck can tip a load.

Frost works into fractured rock and thin soil over the winter and breaks up surfaces on steep lanes and drives each spring.

On the drainage side, that means washed stone where water has to move and a compacted roadstone base where it has to carry weight. Riprap armors culvert outlets, pond edges and slope protection against spring runoff.
