About Us

Joint Seal Waterproofing is a Toronto-based company, offering concrete repair and restoration in Toronto, Mississauga and around all of GTA.

We provide specialized concrete restoration services, including extensive concrete crack repairs through the use of industrial-strength concrete adhesives tested to strict Ministry of Transportation standards.

These concrete repairs are ideally suitable for tunnels, parking structures, elevators, and balconies. Our repairs have been widely used for government projects and high-rise buildings in Toronto, Mississauga and other communities in the GTA and nearby areas.

Repair Methods

Traditionally speaking, two slabs of concrete cannot be fused together when there is a crack. This, however, is not the case through the use of our specialized materials which make monolithic 1.85 MPa adhesion possible. Not only can we repair concrete but also restore it to its original condition, even when wet. It works both on single cracks and concrete surfaces with multiple issues - no need for complete resurfacing. Such rehabilitation is even done on concrete surfaces that are combined with metal structures.

To achieve complete concrete restoration, each crack is repaired by following our specialized method:


All unsound concrete is removed by routing each crack, and surfaces are cleaned in preparation for crack repair.

Monolithic Adhesion

The crack is filled with Polyforce Plus Adhesive which ensures immediate and durable monolithic adhesion (1.8 MPa monolithic adhesion strength).

Crack Filling

Cracks are filled with industrial-strength adhesive and patched with polymer cement.


Waterproofing Polyforce Plus Primer is applied, and the area is painted.
