About Us

GEEG (Geotechnical and Environmental Engineering Group) is an innovative Startup Company of “Sapienza" University of Rome founded by professors, researchers, engineers and technician aimed at sharing with Contractors, Engineering and Chemical Companies and other research groups worldwide the knowledge acquired in years of research activity in the field of chemical treatment of soils.


GEEG was born from the passion of a group of engineers for geotechnics, chemistry and one of the fields which reunites them: the conditioning of the soil for mechanized excavation. The company wants to actively contribute to the scientific progress in the world of tunnels by developing innovative experimental procedures and offering services to optimize the excavation performances, to verify the effects of chemical products in the soil conditioning process and to monitor and reduce the environmental impact of the works.

The pursuit of a shared goal and the passion for research and tunnelling are the cornerstones of the company.


The TBM-EPB mechanized excavation technology involves the use of chemicals to be injected into the soil to modify the chemical-physical-mechanical characteristics of the excavated soil. In lack of specific regulations and consolidated standards at national and international level, the development of experimental methods for verifying the characteristics of chemical products and their interaction with different types of soil is particularly important. GEEG aims to become a reference structure on the subject of chemical treatment of soil thanks to a multidisciplinary scientific approach that meets the companies requirements while promoting a sustainable management of the treatment process.


GEEG is composed of professors of the Faculty of Civil and Industrial Engineering, engineers and technicians, with experience in applied research and in design activities. Creating this startup, the members intend to structure their collaboration and to enhance the potential of everyone.
