Culverts and Storm Structures are the pipes, headwalls, and chambers that carry water under roads and manage site drainage.

Demand for culverts and storm structures in Ottawa (City of Ottawa) comes mostly from government and institutional, technology and commercial, healthcare, and infrastructure and transit. Ottawa's federal government, technology sector, and transit expansion anchor one of Ontario's largest institutional and civil construction markets. Work spans government and institutional site development, transit civil, servicing, and concrete.
Most of it sits around the downtown government core, the Kanata technology park, the industrial and business parks, and the LRT corridors. Much of the Ottawa work is for the federal government, tech firms, hospitals, and the City of Ottawa, each needing the job built to the drawings, to code, and documented.
