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 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 — ensuring 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.
Patching — we do only minimal demolition, using industrial-strength adhesives and polymer cement for thin patch applications, even on walls and ceilings.
Interior Expansion Joints — our fast-curing materials provide immediate bonding, minimising downtime, which is crucial to normal hospital and clinic operations.
Exterior Expansion Joints — we do negative-side injection to repair expansion joints in podium roofs of parking garages, without excavation.
Application Benefits
Minimal Impact on Operations — we coordinate with the client and work during off-peak hours, using fast-setting materials for time-efficient repairs. Our experienced crews always use appropriate PPE and follow specific requirements.
Zero-VOC Materials — specialised fast-setting, odour-free materials ensure no interruptions, especially in crucial areas such as operating rooms and ICUs. Noise and dust are controlled with temporary enclosures.
Smooth Finishes — appropriate finishes of floor surfaces, especially of interior expansion joints, are vital for patient comfort and the transport of equipment.
Our Repair Methods
Medical Facility Waterproofing
We use specialised zero-VOC, odour-free, fast-setting materials so repairs have minimal impact on patients and staff. These are the core methods we follow inside hospitals and clinics.
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 the 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, the injection seals any cracks in the membrane, preventing leaks from recurring.
Ledge Beams
To reach the expansion joint above the ledge beam, it is necessary to drill through close to 40 centimetres of concrete. To ensure proper drilling, a guided rail drill is used.
Filling the entire volume of the expansion joint with soft rubber removes any accumulated water and creates permanent adhesion to the concrete slabs, allowing the entire structure to keep operating as it was originally designed.
Common questions
Frequently asked questions
How do you handle noise and dust in a medical facility?
We use noise-minimising, dust-controlling barriers and work off-peak — nights and weekends.
What materials do you use in medical facilities?
Specialised no-VOC materials that minimise odours.
How is access to critical areas maintained?
Through close coordination with facility authorities on the work schedule.
