JK Group – Who We Are

JK-MarketWeService-banner

Since our establishment in 1976, as Jeffery and Katauskas Pty. Ltd. It has been our goal to help individuals, developers, architects, structural and civil engineers, local and state government bodies identify potential geotechnical and environmental problems.

The JK Group is a proudly employee owned and managed company that values professionalism through honesty, dependability and integrity. We strive for excellence in practical, innovative and value added solutions.

We understand that the performance of buildings and infrastructure hinges not only their design, but on an understanding of the environment they are built in. Knowledge of the surface and subsurface conditions that can impact on a developmentā€™s integrity is essential to the success of the project. By offering qualified and competent services we give our clients confidence.
