TruSeal Injection Inc. specializes in the restoration sector, where we’ve accumulated extensive experience mitigating water egress from below-grade structures in existing properties. Notable projects include the University of Toronto tunnels, the University of Guelph tunnels, multi-residential high-rise parking structures, and more.

With a shift towards the new construction high-rise sector, developers and builders increasingly rely on our expertise. We’re adept at addressing water egress issues prior to occupancy, during project registration, or as deficiencies noted in performance audits.

Our services also extend to new construction projects, where we provide comprehensive waterproofing solutions for developments. This includes, but is not limited to, positive side waterproofing of foundation structures, ensuring the longevity and integrity of the building from the outset.

Looking ahead, we are expanding our scope to include the mining industry, leveraging our expertise to provide effective waterproofing solutions in this sector.
