LafargeHolcim acquires a stake in XtreeE, of which it becomes one of the reference shareholders

A 20% shareholder in XtreeE, LafargeHolcim France becomes a director and thus joins the co-founders of the company, Vinci Construction Invest and the investment fund Shibumi International.

This operation aims to strengthen the association of technical and R&D know-how between the two companies to accelerate the development and marketing of industrial 4.0 solutions for the sustainable construction of buildings and infrastructure.

3D printing of construction materials is indeed one of the responses to the necessary ecological transition in this economic sector. She allows to :

• limit the quantities of materials used thanks to digital design and manufacturing: up to 60% less concrete on certain projects;
• implementing new structural printable materials with a reduced CO2 footprint;
• realize complex structural elements in printed concrete at controlled costs and deadlines thanks to tailor-made solutions;
• reduce the nuisance of construction sites and improve the quality of construction, thanks to off-site manufacturing.

Thus, in anticipation of the 2024 Olympic Games, the Freyssinet / Lavigne & Cheron Architects / Quadric / XtreeE / LafargeHolcim consortium is already working on the design and construction for Plaine Commune Grand Paris of a 40-meter pedestrian bridge crossing the Saint Denis canal. . Its deck will be entirely made of 3D printed structural concrete, thus reducing the quantities of material required by 60% and therefore the carbon footprint of the structure.

“The ecological transformation of the construction sector and more particularly of concrete also requires the digital revolution and the new environmental performances offered by 3D printing. By strengthening our strategic partnership with XtreeE, one of the most innovative leaders in this field, we are opening a new chapter for our innovative materials and for the evolution of construction methods. "
François Petry, CEO of LafargeHolcim France

XtreeE, developer of an international network for concrete 3D printing

XtreeE aims to accelerate in France and internationally the development of a network of connected industrial 3D printing units.

Indeed, after its pilot plant in Rungis, a first operational system at the École des Ponts ParisTech (France) and the opening in the United Arab Emirates in June 2019 of a second production unit, XtreeE accelerated its deployment in 2020 with two new units, in Japan and the United States. Three other units will see the light of day in 2021. This network should ultimately make it possible to efficiently produce, in the four corners of the globe, tailor-made structural construction elements, based on its technology.

XtreeE will now be able to benefit from LafargeHolcim's strong international presence, its R&D capabilities at its L'Ile d'Abeau (France) site and the strength of prescription of a leading player in innovative construction materials.

“LafargeHolcim's expertise in high-performance concrete, as well as its know-how across the entire construction value chain, will enrich the national and international development of our network of connected 3D printing units. With this network, our customers not only acquire the ability to produce themselves, as close as possible to their market, but also mastery of the digital chain, from design to production ”
Alban Mallet, CEO of XtreeE
