Black Dirt, Stone and Soil Delivery in Clarksville, IA

Planning gravel and aggregate delivery in Clarksville, IA for a wet corner of the yard? Iowa Rock Supply sells Class A roadstone, washed stone, sand and soil in bulk.

This part of the Iowan Surface drains slowly, so the ground stays soft long after the uplands dry out. That decides what you order.

Start with where the water goes. Then pick the stone that moves it.

Materials for Clarksville Projects

Wet ground is a drainage problem before it is a stone problem. Clean rock is washed and open graded, so water moves straight through it.

That makes it the material for French drains, drywells and the buried run that carries a downspout away from the house.

Every product page has a calculator, and quantities are ordered by the ton or by the yard.

Coarse stone for water

Clean rock, sold as 1 inch clean or 1 1/2 inch clean, is the coarsest open stone. Use it in subdrains, drainage tile backfill, pipe bedding and septic rock.

It also backfills behind a retaining wall.

#4 Crushed Stone is heavy drainage, construction entrances and trench bottoms. Iowa quarries usually sell this size as clean rock by the inch.

Riprap handles stream bank armoring, culvert outlets, pond edges and slope protection.

#57 Stone works for drainage runs, subdrain backfill and concrete aggregate. Iowa concrete stone gradations are written D57 and D67.

#67 Stone does the same work at a slightly smaller size.

Mid sizes and drive surfaces

3/4" Crushed Stone is washed and free draining, for a drive surface that lets water through, plus pipe bedding and trench backfill. 3/8" Crushed Stone, sold here as washed chips, is seal coat aggregate, fine drainage and paver joints.

#8 Crushed Stone is fine drainage and paver joint filling. #89 Crushed Stone is the smallest washed stone, for tight bedding.

Railroad Ballast is large angular stone for track beds and severe drainage.

Base, bedding and finish

Class A 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.

Limestone screenings bed pavers and flagstone, fill joints, and top dress a compacted roadstone base.

Washed Sand beds and levels under slabs and pavers. Black dirt, our screened topsoil, covers lawn repair, grading and bed prep.

River Rock and Large River Rock build decorative beds, borders and dry creek beds.

Mason Sand mixes brick and block mortar and fills paver joints. 3/8" Natural Pea Gravel suits walkways, play areas and small drainage runs.

Shredded Mulch holds moisture in beds and windbreak plantings.

Ground and Conditions in Clarksville

Work starts once frost is out and the low gradient ground has drained, and runs to the fall freeze. Low spots stay soft well after the uplands are ready.

That is the window that decides when a load can reach a soft corner.

Across the Iowan Surface, the ground is loamy glacial till planed down by cold-climate erosion, with a thin and patchy loess cover. A residual stone line or pebble band sits near the surface, and large granite and quartzite erratics are scattered through the fields.

Drainage networks here are well established, but stream gradients are low, so water moves slowly. Pockets of old wetland ground still hold water, and limestone aquifers can put groundwater close to the surface.

Sheet wash on the long, low slopes cuts gullies where runoff concentrates.

That is why a drainage layer matters here. Clean rock lets water move instead of sitting against a base.

Hard northern Iowa winters bring a long frozen season and repeated freeze-thaw.
