Ambienta-backed Officine Maccaferri, a civil and environmental engineering solutions provider with a commercial presence in over 130 countries, has acquired CPT Group, an Italian company specialised in advanced mechanised tunnelling technologies and robotic prefabrication systems for underground infrastructure.
Founded over 30 years ago and based in Nova Milanese, Italy, CPT serves global contractors in the tunnelling and infrastructure sectors. Its offering combines robotic prefabrication plants (Robofactory), productivity-monitoring software for tunnel boring machines (TBM), and eco-designed spacers. With operations across Europe, Southeast Asia, and Australia, CPT is recognised for enabling more resource-efficient, safer and faster construction of tunnel linings in geologically complex environments.
With this acquisition, Officine Maccaferri becomes one of the major industrial players globally able to offer a fully integrated tunnelling platform – covering both traditional systems (steel ribs, fibres, gaskets) and mechanised solutions (Robofactory, TBMs, digital technologies).
The combined group will serve a growing €1bn addressable market, further consolidating Maccaferri’s transformation into a technology-enabled leader in sustainable infrastructure.
This transaction represents another step in Maccaferri’s growth trajectory under Ambienta’s ownership. Since Ambienta’s investment in early 2024, the group has executed a focused M&A strategy while continuing to grow organically and advance its ESG commitments.
