Joint Seal Waterproofing is a Toronto-based company, specializing in garage floor epoxy, concrete surface repair and waterproofing, as well expansion joint injection and ledge beam waterproofing. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.
Garage Floor Epoxy
Epoxy coating for floor surfaces offers a range of benefits, from a good-looking glossy finish that can brighten up the interior to a durable surface that can withstand significant, continuous traffic – perfect for parking garages. This coating is oil- and water-resistant, which offers additional protection when applied over concrete repairs.
Under traditional repair methods, patching concrete requires a minimum of two-inch demolition in the affected area. The use of specialized, industrial-strength materials permits thin-patch applications on any surface – including floor/wall corners and stairs, making the job much more cost-effective and faster.
Concrete Crack Repair
Joint Seal Waterproofing specializes in concrete crack repairs through the use of industrial-strength concrete adhesives tested to strict Ministry of Transportation standards, which are ideal for tunnels, parking structures, elevators, and balconies. Our repairs have been widely used for government projects and high-rise building.
Normally, when there is a failure of waterproofing membrane over the surface of expansion joints in the podium roof of an underground parking garage, the entire membrane must be dug out, removed and reinstalled because the traditional repair methods do not allow repairs to be done from the inside (negative side). The required excavation is quite costly and entails vast area closures – which causes extended downtime and inconvenience to the public.
This expensive and highly-invasive repair method can be avoided with the use of a specialized expansion joint application. Our repair method allows for the negative-side injection, which removes the need for excavation. Field experience and track record show the injection repairs to be as effective and long-lasting as traditional membrane resurfacing done through excavation.
Ledge Beam Waterproofing involves the same process as expansion joints, with the added challenge of having to drill through 40 centimeters of Ledge Beam concrete to allow the injection of the expansion joint behind the beam. Our application method is designed to create a long-lasting waterproofing seal and has proved itself through an extensive track record. Application from within the structure (from the negative side) will avoid unnecessary expenses and extensive area closures caused by top-side repair.
Any concrete surface in the garage can be repaired and restored to its original condition.
Garage Floor Epoxy
When epoxy coating is desired as a finish layer for the garage floor, careful preparation is done before proceeding, since such coating does not work on all surfaces.
The concrete floor surface must be completely dry and not have been treated with a concrete sealer. If the floor is painted with polyutherane or latex floor paints, those must be removed to apply the epoxy coating properly.
When patching is required, all loose unsound concrete is removed, and concrete surfaces are cleaned in preparation for patching and restoration.
Patching a ceiling poses an added challenge: due to the lack of adhesion, non-specialized material can simply fall out. 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 concrete.
To repair a crack on any concrete surface, a clearly defined procedure is followed. Cracks are prepped and then treated with specialized, industrial-strength adhesive, after which they are filled with polymer cement and a waterproofing primer.
We avoid costly excavation by working from the inside: we drill injection ports and inject our specialized liquid material which turns into soft rubber. It has tremendous adhesion power capable of binding cracked concrete, and displacing any accumulated water, not allowing it to re-enter. The concrete slabs can still expand and contract due to the nature of the materials injected. At the same time, such injection seals any crack in the membrane, preventing hydraulic pocket accumulation and any future leaks from recurring.
To reach the expansion joint above the ledge beam, it is necessary to drill through close 40 centimeters of concrete. To ensure proper drilling, a guided rail drill is used. It is essential to make precise calculations, so that drill port will end up in between the concrete slabs at the top of the Expansion Joint opening.
Filling the entire volume of the expansion joint with soft rubber will remove all accumulated water, create permanent adhesion to concrete slabs, which allows the entire structure to continue operating as it was originally designed. The pressure of the injection chases the water out all the way to the membrane, sealing the channel, repairing cracks in the membrane and preventing further leaking.
Satisfied Customers at RLV Engineering
I’ve seen Joint Seal Waterproofing at work for several years now, doing a range of concrete repairs and waterproofing jobs in parking garages across the city of Toronto and the GTA. No matter the repair – crack filling or patching on floors, walls, or ceilings, expansion joint injection or ledge beam waterproofing – their highly trained, in-house crews do truly professional work each time.
Joint Seal also does a great job scheduling the work by prioritizing tasks, and keeping the property management informed about the work plan and the latest progress. It is truly reassuring to be working with a company that keeps everything organized and under control, besides providing top-notch waterproofing and concrete repair work that is indeed long-lasting.
I never hesitate recommending Joint Seal to any property management company for which I do consulting because I know they will deliver consistent high-quality work, while maintaining constant communication with their clients, staying attentive to their needs.

We have enjoyed over three years of a great working relationship with Joint Seal Waterproofing, as we’ve continued hiring them for diverse waterproofing and concrete repair projects. It has been a very positive experience: we know exactly who will be doing the repairs and can expect high-quality work time and time again, since they send the same in-house crews. They also do a great job keeping us informed on their work progress and being available whenever we have questions or comments.
Back in 2016, we hired Joint Seal to repair ceiling cracks on our parking garage ceilings and do envelope waterproofing. They removed all of the delaminated concrete and did a superb job completely restoring all of the concrete surfaces that required repair. Later we called them back to fix floor cracks and the garage entrance walls (which represented an extra challenge due to rusting around the cracks, but after the repairs, they were as good as new). In 2018, we hired them again to repair cracks in the storage rooms. They did wonderful work once again – not a trace of rust or cracks was left, and the area never leaked afterwards.
Should any other areas of our building require concrete repairs or waterproofing, we will definitely keep Joint Seal Waterproofing in mind. We know they will do highly professional work that will actually last for many years.
