Bulk Aggregates for Drainage in Montour, IA

Iowa Rock Supply handles gravel and aggregate delivery in Montour, IA, and the ground here sets the order. Class A roadstone is the crushed limestone base course with the fines left in, so it binds and compacts under a drive, a parking pad or a farm lane.

Across the Iowan Surface, low stream gradients mean water moves slowly and low pockets hold it.

That makes washed stone the material many jobs around here start with.

Materials for Montour Projects

Washed stone is open graded, so water moves straight through it instead of sitting against a foundation or a slab. Clean rock is the coarse option for subdrains, drainage tile backfill, pipe bedding and the fill behind a retaining wall.

It is sold by the inch, and 1 inch clean and 1 1/2 inch clean both work in a trench.

For a downspout run or a drywell, the stone has to stay open. 3/4" Crushed Stone is a free draining stone for pipe bedding and trench backfill, and it also surfaces a drive where a loose, open material is wanted.

Finer washed stone handles tight spots. 3/8" Crushed Stone is the washed chip Iowa quarries sell for seal coat aggregate, fine drainage, paver joints and a thin top dressing.

Where the ground needs to hold up rather than drain, roadstone takes over. Class A Roadstone is the standard base for drives, 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.

Sand and soil finish the work around a drainage job. Washed Sand beds and levels under slabs and pavers, and Top Soil, which Iowa yards call black dirt, repairs a lawn after a trench is closed.

Delivery to Montour and the Surrounding Area

Montour sits in Tama County, and delivery covers the town and the surrounding area, including Tama, Toledo, Dysart, Traer and Gladbrook. You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout.

Each product page has a calculator if you need to size the load.

A dump truck tips the load on site in one pile, so it helps to have the spot clear before the truck arrives. Bulk delivery works the same way for a farm lane outside town as it does for a driveway in Montour.

Ground and Conditions in Montour

Work here starts once frost is out and the low gradient ground has drained, and it runs to the fall freeze. Low spots stay soft well after the uplands are ready, so timing a delivery matters as much as the material itself.

The Iowan Surface ground is loamy glacial till with a thin, patchy loess cover and a pebble band near the surface. Limestone bedrock is shallow along the eastern edge, and groundwater can sit close to the surface where the old wetland pockets remain.

That shallow water is why a drainage layer earns its place. Sheet wash on the long, low slopes and gully cutting where runoff concentrates both push water toward a foundation, a lane or a trench.

Open graded stone gives it somewhere to go.

Northern Iowa winters are long and frozen, with repeated freeze and thaw that lifts gravel drives, walks and slabs each spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
