Our Story

Sergio Salvi was born in 1951 and is from San Piero in Bagno (FC). He worked for Fondedile from 1973 to 1979. He moved to Monterotondo and started his own business in 1980. At that time Sergio was the only employee of his own company CRM Srl. During the 80’s Sergio travelled all over Italy to help drilling companies to solve the most challenging problems (drilling rigs failures, design and manufacturing of new drilling tools). In 1986 he gave his support to Prespali in a job site for tunneling where double fluid jet grouting treatment and rotopercussive drilling were required . The idea of using an high pressure rubber hose instead of an inner steel pipe inside the rods for double fluid jet grouting stemmed from that experience . (CRM Srl jet grouting rods with the inner high pressure rubber hose are now sold all over the world and became a characteristic note of CRM Srl jet grouting product.). Sergio’s ability to find cleaver solutions get quite renowned and job sites kept calling him. Sergio needed someone to give him some proper support and in 1994 found the perfect match Luca Gastaldi. He industrialized the vast majority of CRM Srl product and took the company to the main exhibit events. In 2000 Marcello Sidoni (an aeronautical engineer from Arrow Spa) joined CRM Srl. Together with Luca he made CRM reach very high design and quality standards. Crm Srl is now a 40 people company whose drilling products are sold in the 5 continents.
