Parking Garage
Repairs & Waterproofing

Ledge Beam Waterproofing

Our specialized application methods allow us to repair even those
expansion joints that are located behind ledge beams.

Efficient Expansion Joint Repairs

Waterproofing expansion joints from inside makes it unnecessary
to excavate parking garage podium roofs.

Wall/Ceiling Leak Repairs

Our specialized materials allow us to do wall/ceiling patching, which is
not efficient with traditional methods.

Benefits

Cost Savings

Unlike with traditional methods that require a two-inch demolition of concrete surfaces, we can do patching as thin as 5 mm.

No Extensive Closures

Since we can do most repairs from the inside, there is no need for extensive parking garage closures.

No Forming Required

The use of industrial-strength adhesives and polymer cement allows us to patch walls and ceilings without forming.

About Us

Joint Seal Waterproofing is a Toronto-based company, specializing in parking garage floor epoxy repairs, concrete surface repair and waterproofing, as well expansion joint injection and ledge beam waterproofing.

Our services cover a vast geographical area, from Toronto and Mississauga to Hamilton and the surrounding GTA communities.

Specialized materials and repair methods allow us to perform cost-effective repairs, avoiding extensive closures.

Repair Methods

Garage Floor Epoxy

Epoxy coating for concrete surfaces offers a range of benefits, from a good-looking glossy finish to a durable surface which works perfectly as traffic coating.

Careful preparation is done before applying epoxy coating because it does not work on all surfaces. Concrete flooring must be completely dry and not have been treated with a concrete sealer. If the floor is painted with polyurethane or latex floor paints, those must be removed to apply the epoxy coating properly.

Patching

The use of specialized, industrial-strength materials permits patches as thin as 5 mm.

All loose unsound concrete is removed, and concrete surfaces are cleaned in preparation for patching and restoration of balcony slab geometry.

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.

Crack Repair

Thanks to monolithic adhesion provided by our products, the repaired surface is fully restored.

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. Cracks can also be repaired with epoxy, if desired.

Expansion Joints

We avoid costly excavation by working from the inside (when repairs must be done under the podium roof): 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.

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.

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.

FAQ

For more information,

Q: How are leaks fixed in garages?

If the water is leaking through cracks on walls and ceiling, they are fixed (Joint Seal’s specialized materials allow for patching even on ceiling and walls, without using forms). If leaks occur through expansion joints, these are waterproofed – even if they are sitting behind ledge beams. Our materials make it possible to do such repairs from inside the garage, which avoids excavation.

Q: Do cars need to be moved during repairs?

Yes, to prevent any possible damage to vehicles and to give proper access to the areas that require repair. They will only need to move temporarily, during the repair.

Q: Is the ground above underground garages always excavated?

It is not necessary with our specialized methods and materials. We can do expansion joint injection from inside the garage, which makes excavation completely unnecessary – the expansion joints and any cracks in the membrane on top are sealed with our liquid rubber materials.
