Retaining Walls · Union, Kentucky
Retaining Walls for Union Homes and Hillsides
Union carries the newest housing stock in Boone County, with a median build year around 2005 and a median home value near $383,000, the priciest housing anywhere in our coverage area. The city nearly tripled between 2000 and 2020, Union Promenade broke ground on US 42 in 2022, and subdivision building keeps rolling along KY 536 and KY 237. Homes at that value come with backyard plans to match, and on Union's rolling upland a lot of those plans start with a wall: holding the grade beside a walkout, terracing a slope into patio levels, or squaring up a yard the builder left on a tilt.
The short answer
We build retaining walls across Union: terraced systems for the big rolling backyards along US 42 and KY 536, walkout-side walls for new builds, and engineered block walls with drainage behind every course. From our Crittenden yard it's roughly 15 road miles up I-75, and we quote from a site walk. Call 859-910-9272.
The soil is the part of the plan most wall quotes skip. Union's broad ridges sit on Rossmoyne, a loess cap over old glacial till with a slowly permeable fragipan about two feet down, and the county soil survey flags shrink-swell clays in the lower layers as a building limitation. That clay swells when it's wet and shrinks when it's dry, which is the worst possible material to pack behind a wall. We back our walls with clean stone and drain tile instead, so the wall never feels that cycle. Where the ground breaks toward the Gunpowder Creek branches, Faywood and Jessup take over, and Faywood hits limestone at 20 to 40 inches, so deeper cuts down there can find rock.
Union also sits inside the Gunpowder Creek watershed and was a named partner in the plan that got the creek off Kentucky's impaired waterways list in 2022, so sediment control on a wall dig here is done properly, not performatively. We're about 15 road miles from our yard near Crittenden, up I-75 to exit 178 and west on Mt Zion Road, and one call covers the excavation, the wall, the drainage, and the finish grade.
What makes Union ground different
Shrink-swell clay behind the wall
The county survey flags the clays in Union's subsoil for shrink-swell behavior. A wall backfilled with that native clay gets pushed every wet season, so ours get clean stone backfill and drain tile that give the water an exit.
A fragipan two feet down
Rossmoyne's pan perches winter water near the surface across Union's ridges. Wall drainage here has to be piped out to daylight, because the ground under the wall can't soak it away.
Walls as part of a bigger backyard
With the newest housing in Boone County, Union wall projects usually run alongside patios, walkouts, and outdoor living plans. One contractor carrying the wall, the drainage, and the grade keeps all of it on one schedule.
Gunpowder Creek accountability
Union helped get Gunpowder Creek delisted in 2022 after a decade of stormwater work. We keep wall digs buttoned up with proper erosion control so your project stays on the right side of that effort.

Retaining Walls in Union: your questions
How much does a retaining wall cost in Union, KY?
It moves with height, length, access, and how the wall ties into the rest of the backyard plan. We walk the site, look at the water, and give you one firm number that includes the excavation, the drainage, and the cleanup, not a wall price with surprises behind it.
Can you terrace a steep backyard in Union?
Yes, and on Union's bigger lots a terrace often beats one tall wall. Stepped walls spread the load, drain better, and turn a single slope into two or three flat levels you can actually use. Each terrace gets set back and drained on its own.
Do you coordinate retaining walls with patios and outdoor living projects in Union?
That's the way we prefer to work. The wall, the drainage, the finish grade, and the seed and straw come from one crew, and we sequence around your patio or builder so the whole backyard finishes as one project instead of three overlapping ones.
What soil problems affect retaining walls in Union?
Two big ones: a fragipan that perches winter water behind the wall, and shrink-swell clay that pushes on anything holding it. Both have the same answer, clean stone backfill and drain tile with a real outlet, which is standard on every wall we build here.
