Repairs & Waterproofing

OR & ICU Floor Repairs

Specialized fast-setting, odor-free materials ensure no interruptions
in such crucial hospital areas.

Zero-VOC Materials

Our insured, well-trained, specialized in-house crews always use
materials appropriate for hospital settings.

Minimal Impact on Operations

Not to disrupt operations, we coordinate with the client and work
during off-peak hours.


Highly Trained Crews

Our crews experienced in specialized work always use appropriate PPE and follow specific requirements.

Noise & Dust Control

Temporary enclosures and working mostly during off-peak hours mitigates noise and dust levels.

Smooth Finishes

Smooth finishes of interior expansion joints are vital for patient comfort and equipment transport.

About Us

Joint Seal Waterproofing offers a turn-key approach to managing large-scale projects, acting as the Project Manager. We provide engineering consulting and do specialized work – elevator waterproofing, interior and exterior expansion joint injection, ledge beam waterproofing, as well as parking garage repairs and waterproofing (crack injection and patching).

For non-specialized work, we act as a General Contractor, ensuring a hassle-free experience. We make certain the work done is of high quality, by carrying out inspections after the job is completed.

As a self-managed company, we do careful monitoring throughout the repair process and provide continuous updates on our progress.

Repair Procedures

Specific Requirements

Since clinic and, especially, hospital operation cannot be suspended at any time, appropriate materials must be used, and specialized application procedures must be followed to ensure there are no interruptions. This requires using low-VOC materials and doing most of the work at night.


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.

Crack Repair

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.

Expansion Joints

Injection ports are installed, allowing our specialized materials to be injected. 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 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.
