Culverts and Storm Structures are the pipes, headwalls, and chambers that carry water under roads and manage site drainage. In London, Harrowgate Group takes on culverts and storm structures end to end: the site is surveyed and scoped, the work is built and managed on site, and the project is completed to the engineered plan.
In London, culverts and storm structures are typically needed for roads, crossings, and site drainage. Moving water under and across a site without washout or flooding are the recurring drivers; each London project is sized to its own situation, not a one-size approach.
What drives culverts and storm structures in London (Middlesex County) is advanced manufacturing, logistics and distribution, institutional and healthcare, and commercial development. London anchors Southwestern Ontario's largest commercial, industrial, and institutional construction market, with strong 401/402 logistics growth. Work spans industrial site development, servicing, institutional and healthcare work, and paving.
Most of it sits around the Innovation Park and Veterans Memorial industrial lands, the 401/402 corridor, and the hospital and university district. Harrowgate Group regularly builds culverts and storm structures for London clients like manufacturers, distributors, hospitals, universities, and the City of London, each project carrying its own site and requirements.
Across London, culverts and storm structures covers a real range of property, advanced manufacturing, logistics and distribution, institutional and healthcare, and commercial development. Each calls for a different response, so Harrowgate Group scopes every London project to the building and its use rather than one playbook.
London conditions shape the response: large greenfield industrial buildout, 401/402-corridor servicing, and institutional-campus growth. Harrowgate Group sets the methods, materials, and equipment for those exact conditions on every London project, working to the site conditions and the engineered drawings rather than a regional default.

The crew builds to the engineered drawings and coordinates the inspections and approvals, so nothing on the London project falls between design, permit, and field.
