Water infrastructure specialists in Quebec are now part of one of the province's larger general contracting organizations. Pomerleau has completed its acquisition of Groupe ALLEN, a Quebec-based general contractor with close to 80 years of experience in water treatment, process mechanics, directional drilling, formwork and earthwork.

Combined Water Infrastructure Capabilities

Groupe ALLEN's work spans several specialties that support water and civil infrastructure delivery, including treatment facilities and process mechanics as well as drilling, formwork and earthwork. The two companies describe their expertise as complementary. They point to aging assets, population growth and evolving environmental requirements as factors that will continue to drive investment in water infrastructure.

Pomerleau President and CEO Philippe Adam has framed the objective as building on Groupe ALLEN's existing foundations and supporting its next stage of development while preserving the qualities behind its success. He also indicated that the combined companies are positioned to help communities meet infrastructure needs in Quebec over the coming decades.

Subsidiary Structure and Continuity

Groupe ALLEN is now a subsidiary of Pomerleau. It will continue to operate under its own name, and its leadership team and management remain in place. Clients, suppliers and specialized subcontractors will continue to work with the teams they already know.

The companies expect the combination to offer a broader range of expertise, greater capacity to deliver large-scale projects and new development opportunities for employees. Financial terms and any project commitments tied to the transaction were not disclosed.

Groupe ALLEN Chief Executive Officer Jean-Philippe Lefebvre views the partnership as a continuation of the company's path, one that gives it the resources to accelerate its next phase of development while maintaining its identity.

What It Means for Quebec Water Infrastructure Owners

For Quebec owners of water and wastewater assets, the transaction links a general contractor with a specialist in treatment facilities and process mechanics. Owners that work with Groupe ALLEN, along with its suppliers and subcontractors, will see no change in the teams or management they deal with, since the company keeps its name and leadership.

Contractors and specialty trades working in the Quebec water sector may also want to watch how the added capacity for large-scale projects shapes procurement and partnership opportunities. The companies have not announced specific projects or an integration timeline.
