About Deep Excavation LLC

For some engineers Deep excavations are a form of eclectic art. Almost never seen by the public except for the rarest occasion. One of the major survivors of 9-11 was the "Bathtub" of the World Trade Center. One of the first gigantic slurry wall excavations in the United States. Perhaps the souls of the innocent victims braced the slurry wall and New York. Geotechnical engineers together with other rescue crews gave their heart and passion at all levels. Our profession aims for the sky by going deep underground with imagination and skill.
