An exceptional remediation project completed nine months ahead of schedule.
The Wolf Creek Dam on the Cumberland River in southern Kentucky is nearly 2 km long and supports hydroelectric generation, flood control, navigation and recreational activities. Following discovery of regressive erosion in the underlying karsts, a contract was awarded to the Treviicos- Soletanche joint venture to rehabilitate the foundations of the dam.

To solve the problem, the joint venture built a barrier wall behind a 52,000 sq. metre, 1.8 metre thick, 85 metre deep diaphragm wall. The 91,000 sq. metre barrier wall, which combines secant piles and Hydrofraise® panels, runs through the embankment and extends downwards through 50 m of clay and 35 m of rock.
The project, which won a Deep Foundations Institute award, was handed over in 2014 following four and a half years of work.
