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.

Toronto (ON)

Made a reservation for Saturday, February 13th. Castaway has become my go to restaurant when I'm craving a steak. Service has always been great and I'm glad they're open again. It's always great to see Derek serving drinks at the bar next to the reception desk. Derek makes the most delicious drinks, so be sure to seek him out! Our server ended up being Manny that day and he was great. I've never had a bad server, which is one of the many reasons I keep on returning to this place.

Came here for the first time today and the whole experience was a 10/10. Elaine was so nice and professional and managed to make me feel super comfortable. The place is super neat and I've gotten honey waxing at other places but I think this is the least painful experience I've had. I'll definitely be coming back and would be happy to recommend Elaine to all my friends and anyone looking at this review.
