Joint Seal Waterproofing is a Toronto-based company, specializing in concrete surface repair, waterproofing, and decorative finishes. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.
Repairing a concrete surface is just part of the work – waterproofing it and applying protective coating to ensure long-lasting repair is equally important. We take it even further and provide a great-looking decorative finish that protects the concrete surface even more.
One of the most challenging concrete surface repairs can be balcony slope reversal. In some cases, the balcony slope becomes either flat or inverted towards the unit.
Balcony slope reversal is not possible with traditional repair methods, as they cannot produce thin-patch application where patch thickness varies between 0.25 and 0.01 inches (traditionally, patching requires a minimum of two-inch demolition in the affected area). The use of specialized concrete adhesives and polymer cement permits thin-patch applications, making the job much more cost-effective and faster.
After the concrete surface is fully repaired, protective coating is applied to ensure long-lasting waterproofing.
A fully repaired and waterproofed concrete surface is protected with the final layer of specialized UV-resistant, non-slip paint which provides a nice decorative finish.
Specialized paint used as the top layer in concrete surface repairs, helps to further protect the restored surface while making it look good.
A concrete surface – besides possibly needing slope reversal or leveling – might also require patching and/or crack repair, before a protective coating and a decorative finish is applied.
All loose unsound concrete is removed, and concrete surfaces are cleaned in preparation for patching and restoration.
Under traditional repair methods, patching concrete requires a minimum of two-inch demolition in the affected area. The use of industrial-strength specialized adhesive and polymer cement permits thin-patch applications, even on walls and ceilings. The combination of these materials creates a monolithic patch which is able to restore structural integrity of repaired slab.
To repair a crack on any concrete surface, a clearly defined procedure is followed. Cracks are prepped and then coated with specialized, industrial-strength adhesive, after which they are filled with polymer cement and sealed with a waterproofing primer.
