IATT is a non-profit association, founded in 1994, which promotes the advancement of scientific and technical knowledge in the field of trenchless technologies (no dig) by promoting its diffusion among public bodies and administrations, service network management companies , companies, technicians, researchers and students. It includes the major Italian companies managing service networks, as well as university and research institutes, industrial companies active in the production of no-dig systems, specialized companies, consultants and professionals in the sector, which through a direct and constructive comparison they are contributing to the spread of the no-dig culture also in our country. IATT is affiliated to the ISTT - International Society for Trenchless Technolog y (based in London), an institution to which 29 other associations representing 33 European and non-European countries belong. Both individuals (ordinary members) and legal persons (institutions, companies, institutes and university departments) can enroll in the IATT. Each member receives the magazines “Italia No Dig” and “Trenchless Works”. Why dig trenches when there are better solutions? No-Dig essentially means researching and applying technically advanced solutions to limit road tampering, excavation and land handling, reducing the disturbance to economic, residential or leisure activities that take place near construction sites. These are therefore executive technologies that make it possible to significantly reduce socio-environmental impacts by 70%, energy consumption by 56% and accidents on construction sites by 70%, which normally accompany works with open pit excavations.
