What drives sheet and torch-on waterproofing 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.
The work concentrates around the Innovation Park and Veterans Memorial industrial lands, the 401/402 corridor, and the hospital and university district. Much of the London work is for manufacturers, distributors, hospitals, universities, and the City of London, each needing the job built to the drawings, to code, and documented.
The mix in London, advanced manufacturing, logistics and distribution, institutional and healthcare, and commercial development, means each sheet and torch-on waterproofing project starts from the specific structure, not a template, when Harrowgate Group scopes it.
