This part of the Iowan Surface has loamy glacial till under a thin, patchy loess cover, with a pebble band near the surface. That ground shapes what you put under a drive or a building pad.

Delivery to Allison and the Surrounding Area

Order online and pick your quantity by the ton or by the yard. Each product page carries a calculator, so you can size the load before you check out.

At checkout you choose a delivery date, and a dump truck tips the load in one pile at the site. Iowa Rock Supply delivers across Allison and the rest of Butler County, including Parkersburg, Shell Rock, Clarksville, Greene and Aplington.

Bulk loads go straight to a farm lane, a building site or a driveway. Have the drop spot clear before the truck arrives.

Materials for Allison Projects

Raising grade and building pads start with fill and sub-base. Fill dirt does the bulk of the lifting, then a roadstone course goes over the top to carry traffic.

For a new drive or a lane that takes heavy equipment, start with 1 Inch Roadstone as the coarse lower course. Cap it with Class A Roadstone, the 3/4 inch crushed limestone base course with the fines left in so it binds and compacts.

Where a drive or lane has thinned out, Driveway Gravel tops it over a compacted roadstone base. For a garden path or walkway that wants a finer surface than drive rock, use Walkway Gravel.

Drainage is its own material. Clean Rock is washed and open graded, so water moves straight through it.

Use it for subdrains, drainage tile backfill, pipe bedding and septic rock.

Wet ground and low spots call for Fill Dirt to bring grade up before anything else goes down. For lawns and beds after grading, Top Soil is the screened black dirt Iowa yards ask for.

Ground and Conditions in Allison

Across the Iowan Surface, the ground is loamy glacial till planed down by cold-climate erosion. A thin, patchy loess cover sits over it, and a residual stone line or pebble band runs near the surface.

That pebble band and the till underneath move when water gets in. An under-built base on this ground pumps, shifts and ruts, so the fill and sub-base have to be right before the surface course goes on.

Drainage here is well established but the stream gradients are low, so water moves slowly and pockets of old wetland ground still hold it. Limestone aquifers keep rivers running in dry spells and can put groundwater close to the surface.

Erosion shows up as sheet wash on the long, low slopes, gully cutting where runoff concentrates, and bank scour after heavy rain and thaw. Riprap at a culvert outlet or a pond edge takes that energy instead of your soil.

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, so plan around the wet ground.

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

Questions from Allison Buyers

What is the best base under pavers in Allison?

Class A roadstone is the compacted base course for pavers, with the fines left in so it binds. Bed the pavers themselves on limestone screenings, the 3/8 inch minus material, and use it to fill the joints.

On the loamy glacial till here, get the fill and sub-base right first, because an under-built base on this ground moves.

Do you supply contractors working in Allison?

Yes. Iowa Rock Supply sells bulk gravel, crushed stone, sand, topsoil and aggregates to contractors and homeowners in Allison and across Butler County.
