Joint Seal Waterproofing is a company based in Toronto, specializing in balcony repair and waterproofing. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.
Typical scope of balcony repair and waterproofing consists of surface patches, crack repairs, and a decorative, UV-resistant, waterproofing finish. In some cases, the slope of the balcony floor needs to be reversed to drain the water away from the unit wall.
No matter how severe the damage, our in-house, well-trained professionals will leave your balcony completely waterproofed and looking great for many years to come!
All loose unsound concrete is removed, and concrete surfaces are cleaned in preparation for patching and restoration of balcony slab geometry.
Under traditional repair methods, large parts of the balcony slab would require complete demolition and recasting. The use of specialized concrete adhesives and polymer cement permits thin-patch applications, making the job much more cost-effective and faster.
Balcony Crack Repair
Crack repair – whenever possible – is the most cost-effective way to avoid future extensive balcony repair. Traditionally speaking, two slabs of concrete cannot be glued together when there is a crack. Our specialized materials make monolithic 1.85 MPa adhesion possible, which allows for complete concrete repair and restoration. It works both on single-defined and multiple cracks.
Balcony Decorative Protective Finish
After the balcony slab is fully repaired, protective coating is applied to ensure long-lasting balcony waterproofing. It is followed by a final layer of specialized UV-resistant, non-slip paint with a nice decorative finish.
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.
