Foundation repair in Triune, TN
Triune sits in east Williamson County, halfway between Murfreesboro and Franklin, on gentler soil than much of Rutherford County.

Halfway to Franklin
Triune grew up around the crossroads of State Route 96 and US 31A/41A, just north of where those roads meet I-840. The first recorded settler, William Jordan, built a log cabin here in 1796, and the community went by Hardeman's Crossroads and Flemingsburg before settling on Triune. The Wilson Branch of the Harpeth River runs through it. Triune is unincorporated and is not its own Census place, so we do not quote housing figures for it.
It is also the only community on this site where Williamson County rules apply, and that changes the licensing picture, which we cover below.

Gentler soil, but still check drainage
The USDA maps the center of Triune as Stiversville silt loam on 5 to 12 percent slopes, eroded. Stiversville has the lowest shrink-swell rating of any soil we mapped for this site, in the low class, with rock at about 45 inches. That is generally good news for foundations. It does not make a house immune. Sloped lots still send water toward the uphill side of a foundation, and a house built on fill can settle no matter what the native soil is.
Ground near the creek is a different story. Low ground along the Wilson Branch can stay wet after heavy rain, and wet soil against a foundation or under a crawl space causes most of the moisture and wood rot problems contractors see.
New homes and older ones
The Triune area has older farmhouses near the crossroads and newer subdivisions spreading out from I-840. In the newer homes, the usual issue is a corner or a garage slab settling over fill. In the older ones, it is sagging crawl space framing and tired masonry piers. A contractor should tell you which one they think you have, and why, before they talk price.
Licenses in Williamson County
Williamson County is not on the state's list of counties that adopted the home improvement license law. Tennessee's contractor license still applies to any job of $25,000 or more. For smaller jobs, ask for insurance and a written contract, and look the company up at verify.tn.gov anyway. Tell us you are in Triune so we match you with a contractor who covers Williamson County.
What to tell a contractor about your Triune home
Triune is about 18 miles from central Murfreesboro. Ask whether the contractor works this far out often and whether the inspection is still free at that distance. We do not have reliable Census housing figures for Triune, so start with what you can see. Vents along the base of the outside walls usually mean a crawl space. No vents and a concrete floor inside usually mean a slab.
USDA soil maps show Stiversville silt loam, low shrink-swell, rock near 45 inches at the center of Triune. Soil maps describe typical ground, not your lot, so ask whether the contractor wants a soil test or an engineer's report before quoting piers. Williamson County is not one of the nine counties that use Tennessee's home improvement license, so for jobs under $25,000, ask for proof of insurance, references and a written warranty. Jobs of $25,000 or more still need a state contractor license.

§ FAQ
Triune foundation questions
Is Triune soil better for foundations than Murfreesboro soil?
The soil mapped at Triune's center is Stiversville silt loam, with a low shrink-swell rating and rock near 45 inches. That rating is lower than most mapped soils around Murfreesboro. Your own lot can still differ, especially on fill or near Wilson Branch of the Harpeth River. Drainage still matters on any lot.
Do Rutherford County license rules apply in Triune?
No. Triune is in Williamson County, which has not adopted the home improvement license law. The state contractor license still applies at $25,000 and up. For smaller jobs, ask for proof of insurance, references and a written contract. Check any license at verify.tn.gov before you sign, whatever the size of the job.
