About us

GEEG (Geotechnical and Environmental Engineering Group) is an innovative Startup of Sapienza University of Rome. Founded in 2018 by professors, researchers, engineers and technicians, GEEG was created to share with institutions, contractors, chemical and engineering companies and other research groups worldwide the results of years of applied research in the fields of mechanized tunnelling, chemical treatment of soils and management of excavated soils and rocks.

GEEG is composed of professors of the Faculty of Civil and Industrial Engineering, engineers and technicians with experience in applied research and design activities. With GEEG, the members intend to enhance their collaboration and harness the full potential of each member of the team.

GEEG supports engineering, technology and materials companies in design, research and analysis processes through the development of experimental procedures and innovative protocols useful every step of the way, from the design to the execution.

GEEG aims to became a key player in the research and development of innovative and sustainable solutions for the civil and environmental engineering, facilitating design and construction processes with dedicated experimental activities
