Dewind One Pass was involved in constructing a cut-off wall to address seepage issues at Tyler Dam in Tyler, Texas. The earthen dam was constructed of clay, but the foundation soil consisted of a very permeable silty sand material. The remediation involved a mixed-in-place soil, cement, and bentonite cutoff wall on the downstream face of the dam, about halfway between the crest and the toe. Dewind won the job, and the City’s consulting geotechnical engineer narrates this video explaining everything about the project and gives them very glowing reviews. It is well worth your time to watch! [Source: Dewind YouTube Channel. Image: YouTube]
