Studio Prof. Marchetti S.r.l. is the manufacturing company of the Marchetti Flat Dilatometer (DMT), the Seismic Dilatometer (SDMT) and other innovative equipment for onshore, nearshore and offshore soil investigation. The company operates on an international basis and has its head office in Rome (Italy). In some countries, it makes use of local distributors, while for other countries it has a direct distribution relationship with clients. DMT and SDMT equipment is currently used in more than 70 countries. The main activity of Studio Prof. Marchetti is to design and supply advanced equipment for worldwide on and offshore soil investigation. The Research and Development department is constantly at work to ensure the most advanced technology, while the marketing specialists are at customer’s disposal for any request of assistance or special need. The company’s aim is to continue to be a reliable reference point for the clients, by basing its relationship on trust and seriousness.

History

Prof. Silvano Marchetti was the inventor and the patent owner of the first DMT blade in the 1974.

In a relatively short time, he was able to build a worldwide reputation for the company, also throughout the collaboration with prestigious University and Research Institutes. More than 1000 papers, including various National standards, ASTM standard, Eurocode, research reports and thesis have been published on the Flat Dilatometer (DMT) by researchers around the world. Prof. Marchetti has made determination of design parameters from DMT in over 1000 construction sites. His passionate research activity went on during the following years and benefited from the innovative breakthrough introduced by Eng. Diego Marchetti, who joined the company in 2001 and gave his contribution to the invention of the Seismic DMT, a combination of the flat dilatometer with an add-on seismic module for the measurement of the shear wave velocity Vs. Since then, the company continued to look ahead, by developing the nearshore as well as the offshore soil test, to meet the growing demands of the clients. Medusa DMT and Seafloor are two innovative and integrated system for that kind of measurement. From 1974, a long path has beentrodden, a lot of progresses have been made, but the same spirit of innovation, the samepassion, accuracy and attention to the detaildefine us and we are proud of that.
