TCEL is comprised entirely of firms that provide geoprofessional services including geotechnical, geological, environmental, construction materials engineering and testing, and related professional services in the State of Texas.

The goal of TCEL is to promote professionalism in the science and practice of geoprofessional services through collaboration, education and training.


Geotechnical engineering, a branch of civil engineering, that uses principles of soil and rock mechanics to evaluate subsurface conditions and materials; determine the relevant physical/mechanical and chemical properties of those materials; evaluate stability of natural slopes and man-made soil deposits; assess risks posed by site conditions; design earthworks and structure foundations; and monitor site conditions, earthwork and foundation construction.

Construction materials engineering and testing (CoMET), generally considered a civil engineering specialty because of its application to construction, encompasses not only elements of civil, structural, and geotechnical engineering but mechanical engineering and materials science along with aspects of the basic sciences of physics (mechanics, dynamics, thermodynamics, and vibration) and chemistry (biology, chemical attack, and corrosion). CoMET engineers and technicians are involved in testing, evaluating, and monitoring the variety of materials and processes used in construction to determine specification compliance and performance characteristics.
