Waterproofing Expansion Joints

Joint Seal Waterproofing is a Toronto-based company, specializing in expansion joints repair and waterproofing. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.

Our Expansion Joint Waterproofing Services

Parking Garage Expansion Joints

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 Beams

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.

Interior Low-VOC Expansion Joints

Fixing interior expansion joints in shopping centers, hospitals and clinics requires a special approach: low-VOC and fireproofing applications must be used, and work is normally carried out at night to minimize interference with the daily operations. Special care must be taken when working in medical facilities: the area being repaired must be kept extremely clean and noise kept to the minimum.

Ledge Beam Waterproofing Made Posible

Even those expansion joints that are located above the ledge beams can be repaired and waterproofed through specialized procedures.

Repair Methods

Waterproofing Expansion Joints

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.

Waterproofing Ledge Beams

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.

In Our Clients’ Words

Satisfied Customers at TCC1151

We’ve been working with Joint Seal Waterproofing for several years now on different projects. Some of them have included waterproofing our parking garage at three different levels. Joint Seal’s professionalism is impressive – we can always rely on their highly trained in-house teams that consistently deliver great results.

Joint Seal performed a range of repairs in our garage, including wall and ceiling patching and crack injection that have actually lasted, to our relief. In the past, we’d had some negative experiences: the repairs were done, but soon afterwards the surfaces started leaking again.

Besides, not every company can waterproof ledge beams due to the added challenge of having to drill through about 40 centimeters of concrete, in order to reach the expansion joints sitting above them, and that’s the kind of work we needed to get done. Fortunately, Joint Seal was able to do it, and now our parking garage is leak-free.

It is the specialized materials and the know-how that sets Joint Seal apart from the other companies we had worked with. The result is long-lasting repairs that actually look good. We will definitely consider Joint Seal Waterproofing again should any other areas in our garage or elsewhere in the building need waterproofing and/or repair.

Satisfied Customers at Vertica Resident Services

Working with Joint Seal Waterproofing was a refreshing experience: their well-trained professionals came in and did all of the repairs and waterproofing more efficiently than we had ever seen before.

They waterproofed all the expansion joints in the lounge room, putting a complete stop to leaking – no more concrete delamination. We also had them repair the basement ceiling. Their specialized materials allow for quick and efficient repairs even on such challenging surfaces, ensuring long-lasting waterproofing.

It is great to know Joint Seal is a company we can fully rely on: we know exactly who will show up to do the work, since they have in-house teams. This means we can be sure to expect the same high-quality results each time. We will definitely consider them in case other areas require repairs and/or waterproofing in the future.
