• Geo Technical Engineering


    Geotechnical engineering utilizes the disciplines of rock and soil mechanics to investigate subsurface conditions. Evaluations also include a review of the geologic conditions. These investigations are used to design, and build foundations, earth structures, and pavement sub-grades.

  • Deep Foundations Testing


    TEG’s deep foundation testing services provide design optimisation and assure long-term performance to ensure that deep foundations cope with greater loads and complex site conditions. We strive to advance proven techniques and develop innovative new solutions to provide enhanced foundation designs.


    Proper selection of quality construction materials is critical. TEG can help to ensure that today’s buildings and infrastructure perform adequately during long time periods. TEG is your trusted partner for construction materials inspections with state-of-the-art construction materials testing laboratories.
