The 27-year-old Bergamaschi, formerly from Bristol Shoguns, joins the north London side following the loss of England prop David Flatman to Bath and veteran prop Christian Califano to French club Agen.
Nevertheless, one of Bergamaschi's new front row partners for the upcoming season will be French hooker Raphael Ibanez, who recently signed with Saracens from Castres.
The club has also bolstered its coaching department with the signing of former Wallaby centre Rod Kafer from Leicester Tigers to help assist their backline.
Saracens CEO Mark Sinderberry was adamant that the new signing would be a huge boost to the club's aspirations for next season, saying: "Emiliano is a tough competitor with exceptional power and good technique in the scrum.
"He is still developing as a player, but his 13 appearances in the Zurich Premiership for Bristol Shoguns last season and his two international caps give a strong indication of what he is capable of."
Bergamaschi also brings with him a rather fearsome reputation as player with incredible raw strength, reportedly breaking a scrummaging machine once during a training session.
Before being awarded his first cap against the USA in 2001, Bergamaschi represented Argentina at Under-19, Under-21 and 'A' level.
During his time Under-19 spell, he was part of the Argentinean side that won the South American championship.
