WATERPROOFING AT HOSPITALS AND CLINICS
Joint Seal is a Toronto-based company whose insured in-house crews always do concrete repair and waterproofing with specialised fast-setting, zero-VOC materials. We coordinate with the client and work during off-peak hours to ensure no interruptions in crucial hospital areas
OUR SERVICES
Waterproofing at Medical Facilities
Our waterproofing solutions for medical facilities include a wide range of interior and exterior repairs – even in such sensitive areas as operating rooms. We do crack repair and patching, expansion joint and ledge beam waterproofing, as well as a floor coating.
Why Hospital Surfaces & Expansion Joints Need Repair
As concrete ages, both concrete surfaces and expansion joints wear out with time, even in the interiors.
When it comes to parking garages and other exterior areas, cracks and delamination are likely to occur sooner due to weather elements.
We repair interior and exterior expansion joints, as well as concrete surfaces to eliminate tripping hazards and stop leaks, to ensure a much longer useful life.
Our Solutions
Crack Repair
We can repair single defined and multiple cracks thanks to the monolithic adhesion provided by our products. Concrete surfaces can be fully restored making slab replacement unnecessary (it is only done when specified by engineers).
Patching
We do only minimal demolition since we can install patches as thin as 5 mm thanks to our specialised materials and application methods. Thin patch applications also allow for floor levelling.
Interior Expansion Joints
Our specialised fast-curing materials provide immediate bonding, making it possible to minimise downtime, which is crucial in maintaining normal hospital and clinic operations.
Exterior Expansion Joints
We are able to do negative-side injection which enables us
to repair expansion joints in podium roofs of parking garages, without excavation. Our liquid rubber materials ensure efficient joint waterproofing and repair on any surface – ceiling, wall, and floor.
Application Benefits
Minimal Impact on Operations
Not to disrupt operations, we coordinate with the client and work during off-peak hours. We use fast-setting materials that ensure time-efficient repairs. Our crews experienced in specialised work always use appropriate PPE and follow specific requirements.
Zero-VOC Materials
Specialised fast-setting, odor-free materials ensure no interruptions, especially in such crucial hospital areas as Operating Rooms and ICUs. Noise and dust levels are also controlled through the use of temporary enclosures.
Smooth Finishes
Appropriate finishes of floor surfaces, especially of interior expansion joints, are vital for patient comfort and transport of equipment.
Crack Repair
To repair a crack on any concrete surface, a clearly defined procedure is followed: cracks are prepped and then treated with industrial-grade adhesive, after which they are filled with polymer cement and a waterproofing primer.
Concrete Patching
Under traditional repair methods, patching concrete requires a minimum of two-inch demolition in the affected area.
The use of industrial-strength adhesives and polymer cement permits thin patch applications, even on walls and ceilings.
The combination of these materials creates a monolithic patch which allows us to restore structural integrity of the repaired slab.
Expansion Joints
Injection ports are installed, allowing our specialised materials to be injected. They have 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 used.
At the same time, such injection seals any cracks in
the membrane, preventing any leaks from recurring.
Ledge Beams
To reach the expansion joint above the ledge beam, it is necessary to drill through close 40 to centimeters of concrete.
To ensure proper drilling, a guided rail drill is used.
Filling the entire volume of the expansion joint with soft rubber will remove any accumulated water, creating permanent adhesion to concrete slabs, which allows the entire structure
to continue operating as it was originally designed.
FAQs
Dealing with Noise and Dust
Q: How do you deal with noise and dust during repairs?
A: We use noise-minimising, dust-controlling barriers, and do the majority of the work during off-peak hours, at nights and on weekends.
Materials Used?
Q: What kind of materials are used?
A: We use specialised, no-VOC materials that help us minimise odours.
Access to Critical Areas
Q: How is access to critical areas maintained?
A: Through close coordination with hospital/clinic authorities to determine the most appropriate work schedule.
