DYWIDAG Sells TAM Groupe in Strategic Push to Core Infrastructure

MUNICH, Germany – January 09, 2026 – By Stephanie Kelly

In a decisive strategic move, global engineering and construction leader DYWIDAG has completed the sale of TAM Groupe, a French market leader in specialized construction products. The transaction, finalized on December 31, 2025, saw 100% of DYWIDAG's shares in the company transferred to Private Assets SE & Co. KGaA, a Hamburg-based investment firm. The divestment underscores DYWIDAG's sharpening focus on its core global infrastructure and energy markets.

The sale marks the conclusion of a chapter for TAM Groupe under the ownership of DYWIDAG and signals a new phase of growth under an investor specializing in corporate spin-offs and special situations. While the financial terms of the private deal were not disclosed, the strategic rationale for all parties involved is clear.

A Strategic Sharpening for DYWIDAG

For DYWIDAG, a company with roots stretching back to 1865, the sale of TAM Groupe is a calculated step in a broader portfolio optimization strategy. The German giant, backed by private equity firm Triton since 2011, has been systematically refining its operations to concentrate on its most profitable and cash-generative product lines. This transaction aligns perfectly with a strategic re-focusing announced in mid-2023, which aimed to bolster sales in core areas like geotechnical solutions, post-tensioning and stay cable systems, concrete technologies, and advanced monitoring services.

TAM Groupe, while a leader in its own right, operates in the manufacturing and distribution of chemical products, fixing systems, and accessories for the construction market. This business, while successful, falls outside DYWIDAG's primary focus on large-scale infrastructure and energy projects encompassing bridges, tunnels, marine structures, and energy facilities. The divestment allows DYWIDAG to redeploy capital and management attention to these core sectors, where it competes as a global market leader.

Hugh Pelham, CEO of DYWIDAG, commented on the transition, expressing gratitude for the partnership. "We extend our sincere thanks to the entire TAM Groupe organization. We believe, along with TAM Groupe‘s President, Joanne Cooke, and her management team, that we have positioned the Company for future growth. We are confident that Private Assets is best positioned to lead TAM Groupe forward in its next chapter.”

This move is consistent with DYWIDAG's recent activities, which include expanding its U.S. operational footprint to better serve its North American geotechnical and post-tensioning clients. By divesting non-core assets like TAM Groupe, DYWIDAG enhances its ability to pursue its vision of making global infrastructure safer, stronger, and smarter through its specialized, high-margin technological solutions.

Private Assets Deepens Its French Portfolio

The acquisition represents a significant move for the buyer, Private Assets SE & Co. KGaA. The Hamburg-based firm has carved out a niche by investing in companies in “special situations,” a category that includes corporate spin-offs like TAM Groupe, as well as medium-sized companies and firms navigating succession challenges. This investment model suggests a hands-on approach focused on unlocking operational value and driving growth in businesses with established market positions but untapped potential.

The purchase of TAM Groupe marks the third major investment in France for Private Assets, signaling a deliberate and expanding commitment to the French market. This growing presence indicates a strategic belief in the region's economic stability and the opportunities within its industrial and construction sectors.

Dr. Björn Schlosser, Président and Managing Director of Private Assets Francs S.A.S, expressed his firm’s enthusiasm for the deal. ”We are pleased to welcome TAM Groupe in our portfolio as PA's third investment in France. We are looking forward to working together with the management team and the employees to further strengthen TAM's market position.”

This statement points to a strategy of collaboration rather than disruption, aiming to build upon TAM Groupe’s existing strengths with the support of a new, focused ownership structure. The goal is not just to acquire, but to actively enhance the company's competitive edge.

A New Chapter for a French Market Leader

At the center of the transaction is TAM Groupe, a respected name in the French construction industry since its founding in 1960. The company’s strength was solidified in the early 2000s through the strategic integration of three market-leading brands: Technique Beton, Artéon, and Mandelli Setra. This consolidation created a powerful entity specializing in essential construction site products, from chemical admixtures and repair mortars to sophisticated lifting and fixing accessories for prefabricated concrete elements.

Under the new ownership of Private Assets, TAM Groupe is poised to begin a new era of focused growth. The leadership of its president, Joanne Cooke, and her management team is expected to provide continuity, guiding the company as it navigates the opportunities presented by the new investment. The backing from Private Assets provides TAM Groupe with the resources to potentially accelerate product innovation, expand its distribution network, and solidify its leadership position.

This new chapter allows TAM Groupe to operate with the agility of a standalone entity, fully concentrated on its specific market segments. It can now tailor its strategy directly to the needs of the French construction sector without being tied to the broader strategic imperatives of a global infrastructure conglomerate like DYWIDAG. The transition is therefore seen as a positive development, offering a pathway to renewed focus and targeted investment in its future success.
