We are a Toronto-based company whose insured in-house crews always do concrete repair and waterproofing with specialized fast-setting, zero-VOC materials.
We coordinate with the client and work during off-peak hours, to ensure no interruptions in crucial hospital areas.



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 specialized work always use appropriate PPE and follow specific requirements.

Zero-VOC Materials

Specialized 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 a specialized, industrial-strength 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 a 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.

Expansion Joints

Injection ports are installed, allowing our specialized 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 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 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 all accumulated water, create permanent adhesion to concrete slabs, which allows the entire structure to continue operating as it was originally designed.
