Structural Slurry Wall and Seepage Control
DFI’s Seepage Control Committee and Slurry Wall Committee merged at the start of 2023.
The mission of the Structural Slurry Wall and Seepage Control committee is to be a collaborative forum to discuss and disseminate best practices for structural slurry walls and seepage control, and to advance the awareness, use and performance of structural slurry wall and seepage control technologies.
Committee Chairs
Co-Chair
Meeok Kim, Ph.D., P.E.
Thornton Tomasetti
Meeok Kim has 19 years of experience with geostructural engineering practice. She received a Ph.D. in civil engineering from Virginia Polytechnic Institute. She serves as a geostructural engineer with Thornton Tomasetti, specializing in the analysis and design of complex below-grade systems such as deep excavations, unique foundations and tunnel access shafts in various regions of U.S. The common denominator of her experience is a system governed by soils and the structures interactions. Kim is an expert on the performance of deep foundation systems, has been involved in various types of slurry wall projects, and has designed dozens of slurry wall and LBE foundations.
