Jennmar Expands Its Global Reach with Acquisition of Weber Mining & Tunnelling SAS

PITTSBURGH, Aug. 8, 2025 – Jennmar, a prominent provider of specialized infrastructure products and services, has recently announced its acquisition of Weber Mining & Tunnelling SAS, a move that greatly enhances its market presence internationally. This strategic acquisition, part of Jennmar’s expansion strategy, positions the company to better meet the burgeoning needs of the global mining community.

Weber Mining, headquartered in France, has a legacy spanning over 60 years in the development of innovative resin and foam solutions. Their products are essential for strata stabilization and support in mining and tunneling operations, solidifying their reputation as leaders in the industry. Through this acquisition, Jennmar is set to not only broaden its product offering but also expand its operational footprint internationally, leveraging Weber's established manufacturing plants in both France and Poland.

A Synergistic Partnership

The acquisition of Weber is not merely a financial transaction; it is a merger of expertise and innovation. Weber’s impressive portfolio of proprietary foam and resin products has continuously evolved through intense research and development, ensuring that it meets the high demands of various sectors within the mining industry. With an international customer base, Weber’s diverse product line complements Jennmar's existing services, creating a more robust suite of solutions for clients.

Tony Calandra, the CEO of Jennmar, expressed excitement about this new chapter, stating, "We have had the privilege of knowing Frank Weber and watching the remarkable growth of the Weber business for over two decades. Welcoming him and his talented team into the Jennmar family is a proud moment for us. Together, we aim to leverage Weber's technical expertise to bolster our operations in Europe and the Asia-Pacific region."

Strengthening Global Operations

The acquisition aligns with Jennmar’s strategy of solidifying its position as a global leader in the infrastructure sector. By incorporating Weber's innovative products, Jennmar can better serve its clients and respond to the increased demand for effective mining solutions globally. In 2025 alone, Jennmar has completed over $150 million in acquisitions across Europe, showcasing its commitment to expanding its international presence and enhancing customer offerings.

Frank Weber, CEO of Weber Mining, emphasized the importance of this partnership: “Our family-owned business has thrived on innovation since 1960. By joining forces with Jennmar, we are taking an important next step for Weber’s future that aligns with our values and commitment to our customers and employees.”

Future Prospects and Operational Growth

Both companies plan to maintain their respective brands post-acquisition, with Weber continuing its operations as Weber Mining & Tunnelling. This ensures that existing services and expertise remain intact, while also integrating Jennmar’s operational scale and technical know-how to accelerate product availability across global portfolios.

The merger also underscores Jennmar's drive toward enhancing operational efficiencies and reinforcing its leadership in manufacturing high-quality safety products. As the mining industry evolves, both Jennmar and Weber are committed to continuous innovation and delivering solutions that prioritize safety and performance.

Conclusion

With this acquisition, Jennmar is strategically positioned for significant growth and enhanced market segmentation, making it a formidable force in the infrastructure sector.
