On December 1, 2025, two proudly Quebec-based general contractors, CONCREA and Tisseur, officially join forces under one name: Tisseur – United to Build.

The name Tisseur and the tagline United to Build, inspired by CONCREA, embody the strength of this union between two major players in the construction industry. The new organization draws on the best of both worlds: CONCREA’s precision and boldness, and Tisseur’s agility and versatility.
