What Is It
Concrete, no matter how thick or what type, remains a porous substrate. Concrete cancer occurs when water makes contact with the structural steel reinforcement bars and causes rust. The steel bars then forcibly expand and deform, breaking apart the concrete that surrounds them. The concrete ‘spalls’, i.e. breaks apart and falls away in chunks.

Selected Projects
The Colgan Approach
Whether we’re project managing, or contracting for a specific skill, we take the time to explore the materials to be restored, conserved, remediated or transformed. We work collaboratively with other experts and manage the needs of multiple stakeholders.
