Case Foundation has been part of Keller since 2020, when several North American companies joined together under the Keller name. Today, the same teams, expertise, and capabilities continue to deliver projects as Keller.
For clients searching for Case Foundation, you are in the right place. Keller builds on that legacy, combining local experience with global resources to deliver safe, efficient, and technically sound geotechnical solutions.
Founded more than 60 years ago in Chicago by Vernon Case, Case Foundation began as a local drilled shaft contractor and played a key role in advancing deep foundation construction across North America. From early drilled shaft applications to complex urban excavation support, the company helped establish many of the methods used today.
That experience continues through Keller, where we apply proven techniques, engineering expertise, and a strong safety culture to meet the demands of modern construction.
