Concrete Repairs in Hospitals & Clinics

Joint Seal Waterproofing is a company based in Toronto, specializing in concrete repairs and expansion joint injection in hospitals and clinics.  Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.

Our Repair Services at Medical Facilities

Concrete repairs and waterproofing in clinics and, especially, hospitals require a special approach. Our insured, well-trained, specialized in-house crews generate no Volatile Organic Compounds (VOCs) or dust, by using temporary enclosures around the work area, as well as specialized materials. Most of the work is carried out in off-peak hours.

We offer 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.

Hospital Hallway Repairs

Special care is taken to ensure a smooth surface over the expansion joints, since there must be no risk of equipment falling (as may happen when patients are walking around the hallways with IV poles).

OR and ICU Floor Repairs

Our in-house crews work quietly, without generating any dust, by installing temporary enclosures around the area to be repaired. Specialized fast-setting, odor-free materials ensure no interruptions in such crucial areas of the hospital.

Exterior Expansion Joint Waterproofing

To avoid costly excavation (which becomes necessary when work must be done on expansion joints in the podium roof of an underground parking garage), we work from the inside, installing injection ports and injecting our specialized liquid material which turns into soft rubber.

Expansion Joints – As Good As New

This hallway expansion joint completely regained its functionality after our specialized methods were applied.

Repair Methods

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 of the original slab geometry.

Under traditional repair methods, large parts of the concrete 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.

Crack Repair 

To repair a crack on any concrete surface, a clearly defined procedure is followed. Cracks are prepped and then coated with specialized, industrial-strength adhesive, after which they are filled with polymer cement and sealed with a waterproofing primer.

Expansion Joint Waterproofing 

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.
