CGL started up in 1994 as Card Geotechnics Limited but that was only half the story as a lot of our work was in the emerging geoenvironmental market.  In 2011 we rebranded to CGL and in 2020 CGL was acquired by Construction Testing Solutions, a leading provider of testing, calibration and consultancy services with an ethos and values aligned to CGL. The shared technical capabilities and regional reach bring added benefits to our Clients as CGL continues to develop its service offerings and provide innovative value-engineered solutions for our many clients.
