Bulk Gravel and Stone Delivery in Guthrie County, IA
Iowa Rock Supply brings gravel, stone and aggregate delivery in Guthrie County, IA to your site. Class A roadstone is the base most Iowa drives are built on, and it leads the list here.
Spring is the driver: snowmelt and rain sit on ground that is still frozen or still clay, and a wet spring pushes base work back several weeks.
Guthrie County spans two ground regions. Around Guthrie Center, Panora, Stuart and Menlo the subsoil is old till under windblown loess, and the clay beneath it does not take water.
Around Yale, Bagley and Jamaica the ground is younger glacial till with kettles that hold water until it dries.
Materials Delivered in Guthrie County
Material is grouped by family: base, washed stone, sand, soil and decorative. Each product page has a calculator, and quantities are ordered by the ton or by the yard.
Base and roadstone
Class A Roadstone is the standard Iowa base course: crushed limestone with the fines left in, so it binds and compacts.
11.
1 Inch Roadstone is the coarser grade, for a new drive, a soft spot or a lane that carries heavy equipment. It is laid under a finer surface course.
Driveway Gravel tops an existing drive or lane that has thinned out, over a compacted roadstone base.
Washed stone
Clean Rock is washed and open graded, so water moves straight through. It goes in subdrains, drainage tile backfill, pipe bedding, septic rock and behind retaining walls.
3/4" Crushed Stone is a loose, free draining drive surfacing, and it beds pipe and backfills trenches.
Limestone Screenings bed pavers and flagstone, fill joints and top dress a compacted roadstone base. 3/8" Crushed Stone is what Iowa quarries sell as washed chips, used for seal coat aggregate, fine drainage and paver joints.
Riprap is revetment stone, specified by class letter under Section 4130. It armors stream banks, culvert outlets, pond edges and slopes against spring runoff.
Sand
Mason Sand mixes brick and block mortar, fills paver joints and beds play areas and arena footing. Washed Sand beds and levels under slabs and pavers, and fills where a clean, free draining grade is wanted.
Soil, fill and mulch
Top Soil is screened black dirt, named for the dark prairie soils the state is known for. It repairs lawns, grades ground and preps beds.
Fill Dirt raises grade, fills low ground and backfills before a roadstone course goes down. Garden Soil is blended richer than plain black dirt for raised beds and planting areas.
Shredded Mulch holds moisture in beds, tree rings and windbreak plantings.
Decorative stone
River Rock is rounded gravel washed out of the Missouri, Mississippi and their tributary valleys. It suits decorative beds, borders and dry creek beds.
Large River Rock handles dry creek beds, splash pads and heavier bank work. 3/8" Natural Pea Gravel covers walkways, play areas, patio bedding and small drainage runs.
Delivery Across Guthrie County
You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load in one pile on site.
Have the drop area clear and reachable before the truck arrives.
Delivery covers Guthrie Center, Panora, Stuart, Menlo, Bayard, Casey, Yale, Bagley and Jamaica. If your lane is soft at the bottom of a grade after rain, the truck still needs solid ground to tip on.
Ground Conditions Across Guthrie County
Water is the whole story here. Around Guthrie Center, Panora, Stuart and Menlo the ground rolls steeply and drains at the surface, but the clay subsoil does not take water.
It perches, runs off, and leaves drives soft at the bottom of a grade.
Around Yale, Bagley and Jamaica the drainage network is young and inefficient. Kettles and closed depressions hold water, and most ground only drains because it is tiled.
Erosion follows the water. The rolling ground around Guthrie Center, Panora, Stuart and Menlo is Iowa's most eroded landscape, with deeply cut streams and gullies after heavy rain.
That is why riprap goes in on slopes and outlets.
Frost depth is commonly 42 inches, and the local building official sets footing depth. Compaction waits for frost to leave the ground and for flat ground to shed its spring water, so base and paver work runs from late spring to the fall freeze.
Choosing the Right Material
Dallas County and Carroll County each span the Des Moines Lobe and the Southern Iowa Drift Plain, the same two ground regions Guthrie County spans. The ground is the same, so the base and drainage choices are the same.
Greene County sits entirely on the Des Moines Lobe, the youngest glacial ground in Iowa: thick, compact pebbly loam till of the Dows Formation, 45 to 60 feet deep, with sand and gravel along old meltwater channels and hummocky, stony ground on the moraine ridges.
That difference matters at the bottom of a grade. Where clay subsoil perches water, a clean open stone drainage layer keeps water moving instead of sitting under the base.
Where till is deep and compact, the base course itself carries the load.
