ABOUT US

For over seven years, Joint Seal Waterproofing has been providing concrete repairs and waterproofing services in Toronto, the GTA and the surrounding areas. We specialize in thin patch applications and expansion joint injection.

 

High-strength concrete adhesives allow us to perform all concrete repairs from inside the elevator pits and underground parking garages, saving on costs and ensuring long-lasting results. The use of polyurea-based waterproofing membranes restores water impermeability of the repaired concrete.

We offer a full range of waterproofing services for commercial structures.
