Order Untreated Base Course and Crushed Stone in Iron County, UT
Utah Rock Supply sells gravel, stone and aggregate delivery in Iron County, UT to contractors and homeowners alike. Some buyers arrive with a plan set that calls out untreated base course by name.
Others are surfacing a drive or bedding pavers for the first time and want the material explained before they order.
Ground here runs sandy and gravelly in places and heavy with expansive clay in others, so the material under a slab or drive matters as much as the surface. Untreated base course is the compacting layer that carries that load.
Materials delivered in Iron County
Untreated base course, shortened to UTBC by Utah yards and crews, is a base course of natural gravel, crushed rock or crushed slag placed on a prepared subbase or subgrade.
It goes under driveways, parking pads, slabs, shed bases and paver work. Size it by top size, 3/4 inch minus or 1 1/2 inch minus, which is how Utah plans and tickets name it.
Natural Pea Gravel, rounded stone for walkways, play areas and pipe surround, and cobble for decorative beds and dry creek beds round out a load. Fill dirt raises grade before a base course goes down.
Choosing the right material
Washington County sits in the same ground region as Iron County, the Southwest Utah ground that runs from the St. George basin to the Escalante Desert.
Sandy, gravelly desert soil over red sandstone and volcanic rock, with heavy expansive clay in places, and alkaline ground low in organic matter throughout.
Because the ground is the same, the material reasoning is the same on both sides of the county line. A compacted base course carries the load, a clean washed stone moves water, and imported topsoil starts a lawn on ground that has little organic matter of its own.
Ground conditions across Iron County
Across this part of the state, summer monsoon cloudbursts and winter frontal rain fall on ground that takes in very little. Clay holds water under slabs and flatwork, and expansive clay moves when it does.
A thin base shows that movement first.
The fix is a base course built to the depth the plan calls for, with a clean drainage stone where water needs a path out. Rounded stone does not compact into a base, and a fines-bearing material does not drain.
Flash flooding in the washes, sheet flow off bare desert slopes and alluvial fans, and wind moving loose sandy ground all shape what stays put on a slope. Riprap armors wash banks, culvert outlets and cut slopes against that runoff.
Working seasons split across the region. The warm low end runs close to year-round, with summer heat rather than frost as the limit, while the Cedar City and plateau end has a normal winter shutdown.
Frost depth is set by each jurisdiction, so confirm the figure locally.
