John L., March Elevator
Joint Seal Waterproofing is our only elevator pit water prevention specialist. It is a one-stop-shop which provides excellent results for any type of elevator pit (block or concrete walls, with a piston or without). JSW is a trusted partner in the March Elevator Family. Their commitment to resolving unique problems in a timely manner has provided our clients with trust in our final product. Great team management and communication, I would recommend JSW any day of the week.
As an owner of multiple 100+ year houses in the west end of Toronto, I've had more than one case of a leaky basement. Joint Seal has always been there when I needed them and did an outstanding job! They are professional and always come up with just the right solution for my issues (big and small), and at a lower cost than other companies.
Best of all – their waterproofing methods actually work! I've never had a leak come back.
You are in great hands with Joint Seal!
For over nine 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.
