Excavation & Grading Contractor in Liberty, MO
We work in Liberty and across Clay County, handling excavation, grading, drainage, and site prep. That means land grading and drainage correction, building pads, gravel driveways and private roads, culvert installation, utility trenching, land clearing, and pond work. Jobs run from a single residential lot to a full commercial pad, for custom home builders, general contractors, developers, and homeowners. Our shop sits 25 miles south in Grain Valley, so Liberty work is a straight run up Route 291.

Local Experience in the Liberty Area
North of the Missouri River, Clay County sits on glacial till under loess. The subsoil runs 35 to 50 percent clay, holds a perched water table from November through April, and hits shale as shallow as 20 inches near drainageways. That is why a pad can proof-roll clean in October and fail after rain in March.
About 70 percent of the area's 36 inches of annual rain falls between April and September, and it sheds off this ground instead of soaking in. Most fixes start with grade, not pipe: intercept flow above the structure, six inches of fall in the first ten feet, fill keyed into the slope. On roads and pads, it is why base depth and compaction pay for themselves.
Who We Work With in Liberty
We work with a mix of contractors, developers, homeowners, and public agencies:
Custom home builders and general contractors
Commercial developers and industrial site work
Homeowners with drainage, driveway, and lot grading problems
Acreage and rural landowners
Paving and utility contractors who need roadway subgrade and base prep
Cities, counties, and public works projects
On larger commercial jobs we run the earthwork as a subcontractor to the general contractor. On smaller sites we handle the whole package.

Serving Liberty & Surrounding Communities
Liberty anchors this page, but we work across Clay County and the northland, including Kearney, Smithville, Pleasant Valley, Glenaire, Excelsior Springs, Missouri City, and the river bottoms south and east of town. Acreage work out that way usually means private drives, ponds, culverts, and clearing.
Frequently Asked Questions
How far does ICON travel for Liberty projects?
Liberty is about 25 miles from our Grain Valley shop, roughly a half hour by way of Route 291. It is an extended service area for us rather than a core one, which affects mobilization but not the scope we can take on.
Why does my Liberty yard or driveway hold water long after the rain stops?
Liberty’s upland soils hold 35 to 50 percent clay in the subsoil, and water that cannot soak down has to be moved across the surface instead. That makes it a grading problem, which is why adding rock to a soft driveway without the right base for clay rarely fixes it.
Do I need a permit to grade or excavate in Liberty?
Disturbing one acre or more requires a land disturbance permit from MDNR, and unincorporated Clay County requires its own at the same threshold. Smaller sites are handled through building permit conditions and still need erosion control, so check with Liberty’s Building Division before work starts.
What makes Clay County soil different from the Jackson County side of the metro?
Clay County’s uplands are glacial till plains mantled with loess, so till turns up on side slopes, while the Jackson County soil survey records little evidence of glacial action. The seasonally wet, high-clay soils common around Liberty do not appear on the Jackson County side at all.
Can ICON work with builders and commercial developers, not just homeowners?
Most of our work is for general contractors, custom home builders, developers, and public works projects. That includes commercial excavation, pad grading to plan elevation, roadway subgrade, and sequencing our earthwork alongside paving and utility crews.
