Johnson Soils Company is part of an integrated approach for superior results.


In 2005, the assets of the firm were acquired by Calisto J. Bertin, PE to form Johnson Soils Company. Prior to that Mr. Bertin, owner of a civil engineering design firm and Mr. Mahle had been collaborating on projects together for 20 years. Combining the firm’s rich geotechnical experience with the larger technical engineering capabilities has enabled Johnson Soils to undertake new challenges.
