About us

Masonry and rebar: the two trades behind every building.

Gruppo Erre Di S.r.l. was founded in Treviglio (BG, Italy) as a firm specialized in third-party masonry and on-site rebar work — the two trades that define quality and schedule on every construction site.

We work alongside general contractors, design offices and private clients, adding industrial and civil construction services when a single structural partner is required.

Our approach is simple: workmanship done right, on schedule, with technical documentation always in order (DURC, Credit Licence, DoP and CE marking per EU Reg. 305/2011).
