Jennmar Expands Global Reach with Weber Mining & Tunnelling Acquisition

Jennmar has broadened its international footprint through the acquisition of Weber Mining & Tunnelling SAS and its subsidiaries, which remain operational under their established name. Inheriting Weber’s decades of expertise in resin and foam solutions for strata stabilization across hard-rock mining, tunneling, and soft-rock mining, the move strengthens Jennmar’s global product portfolio. By integrating facilities in France and Poland plus Weber’s customer relationships across multiple regions, Jennmar aims to enhance its mining and tunneling offerings and support rising demand worldwide.

The transaction highlights Jennmar’s strategic intent to leverage its operational scale and technical capabilities, accelerating the global rollout of Weber’s proprietary products. Completion of over US $150 million in European acquisitions in 2025 further reflects Jennmar’s ongoing commitment to regional growth and diversified solutions for customers.

“At Jennmar, we have had the privilege of knowing Frank Weber and watching the remarkable growth of the Weber business for over two decades, and I’m proud to welcome him and the talented team at Weber to the Jennmar family,” said Tony Calandra, CEO of Jennmar.
