Sheet and Torch-On Waterproofing is membrane waterproofing applied in sheets or torch-applied for durable below-grade and deck protection. Harrowgate Group handles sheet and torch-on waterproofing for North York around the actual ground conditions, loads, and access of each site, built to spec, not to a template.
North York sheet and torch-on waterproofing work centres on foundations, decks, and roofs. The recurring drivers are durable, proven membrane waterproofing for tough conditions, each North York project is scoped to its own situation rather than a standard package.
Demand for sheet and torch-on waterproofing in North York (City of Toronto) comes mostly from commercial and office development, institutional and healthcare, transit-oriented development, and industrial lands. North York's Yonge-Sheppard and Consumers Road centres drive office, institutional, and transit-oriented commercial construction, with the Downsview lands opening major new development. Demand favours mid-rise and institutional site work along the subway and 401 corridors.
Most of it sits around the Yonge and Sheppard centres, Consumers Road business park, Downsview lands, and the 401 employment corridor. Clients such as developers, office and institutional owners, hospitals, and the City of Toronto drive much of the North York work, and no two projects carry the same scope or ground.
North York buildings vary widely, commercial and office development, institutional and healthcare, transit-oriented development, and industrial lands, and the right sheet and torch-on waterproofing approach changes with each. Harrowgate Group reads the property before it scopes the project.
What shapes a North York project is transit-corridor density, aging commercial stock needing retrofit, and servicing around active subway and 401 infrastructure. Each North York project has the methods, materials, and equipment chosen for that environment, matched to the site instead of a one-size approach.

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

Harrowgate Group also serves nearby Toronto, Vaughan, Markham, so projects spanning the surrounding area stay with one team.
Each North York project is completed to its engineered spec, methods, materials, and load or compaction results set to the site and recorded, so what is built matches what was designed and approved.
