Founded in 1975, a member of the ICRI (International Concrete Repair Institute), and ISO 9000 certified, Fissure Fondation inc. / Injection Tomassini specializes in the injection of concrete cracks and resolving foundation issues.
The efficiency of our injection systems and the quality of our synthetic resins allow us to guarantee our crack repairs for 20 years.
The product is non-toxic, contains no solvents, emits no odor, and firmly adheres to the walls, preventing any possibility of water infiltration permanently and without excavation.
By drilling at 45 degrees, our process ensures complete saturation of cracks or expansion joints.
This product can be applied at any temperature.
A large part of the budget is reinvested in research and development This results in the most efficient injection equipment available in Quebec!
In 2015, the company created its first series production of high-performance injection pumps, unique to the company.

Injection in the Lafontaine tunnel
A company that knows how to seal leaks
When I founded the company more than 40 years ago, my biggest challenge was to manufacture an injection system whose efficiency ensured complete saturation of cracks on concrete structures in order to eliminate destruction of properties caused by excavation. To do this, a large part of the company’s budget has been reinvested in research and development, resulting in the development of an injection system whose efficiency allows us to inject cracks twice as thin. than a sheet of paper in a 36 in. foundation, or 1m thick.
This feat motivated me to obtain an ISO 9000 certification. In conclusion; when perfection remains an obsession we remain in constant evolution. Thank you to all our customers and future customers for helping to make our company a great success.

If you detect the presence of cracks in your home, the best thing to do is to call a crack expert to determine if you have active or passive cracks. Whether shrinkage cracks or other types, the Foundation Fissure team can repair concrete cracks quickly and professionally!
Serving our customers for over 46 years.
Fissure Fondation can handle the repair of cracks and micro-cracks of all kinds, such as shrinkage cracks and structural cracks.
Fissure Fondation uses an exclusive injection process for the repair of cracks in concrete structures, offering many advantages to homeowners who need to repair their foundations.
Repairing foundation cracks usually requires excavation along the foundation, which can cause significant damage to the building. Our 45-degree injection technology eliminates damage or destruction to your foundations for such strong and long-lasting results.
Foundation crack repair is done using injections in the center of the concrete structure. Holes are made using a drill to inject exactly in the center of your foundation, which ensures an even and solid application of our product. With a significant portion of our income reinvested in research, our concrete structure injection service is the most efficient in Quebec!
Don’t wait to contact Fissure Fondation! Our team of concrete structure injection experts can repair your foundations all year round: the product can be injected safely in all temperatures, thanks to our state-of-the-art equipment.
The product injected into the foundations is non-toxic, contains no solvents, and gives off no odor for quick and safe application. No need to leave your house! The injection product attaches firmly to the walls, preventing any possibility of water infiltration permanently.
As a property ages, it is common to see cracks appear due to structural movement and degradation of materials. Yes, even concrete has a limited lifespan: after several decades, it begins to weaken.
In winter, the expansion of water naturally present in the earth can put pressure on the walls of a house. This pressure can lead to the formation of cracks, which increase in size depending on the severity of the frost. It is therefore advisable to move water sources, such as gutters, away from the house if possible.
Land subsidence can be caused by urban development, low soil bearing capacity and drought. Clay soils can become particularly fragile during periods of drought, which can cause cracks in properties and damage to house foundations. Fortunately, it is rather rare in Quebec!
The action of water can have significant consequences on the foundations of a building, particularly in regions where there is significant freezing and thawing. Water infiltration can permanently damage foundation walls if homeowners don’t do a quick crack repair.
Beyond aesthetics, the presence of a crack on a wall can have multiple impacts. While some are not serious, others can compromise the entire frame.
A superficial crack is called a “microcrack”. With a width of less than 0.02 mm, the microcracks remain superficial and only affect the coating of the foundation. They are not dangerous, but should be monitored for potential problems (they can leak water and cause moisture problems!). Watch them closely to make sure they are not the first signs of a more serious problem.
This type of crack is less than 2mm wide. Several factors may be involved, but it is most often shocks or non-serious damage. However, it is important to repair and monitor them. Indeed, if they extend, they can weaken the house.
Beyond 2mm in width, we speak of a deep and dangerous crack. Most cross the wall from side to side and are presented in steps, because they follow the layout of the breeze blocks. These are worrisome, as they are usually due to a deeper soil problem or structural defect. However, they can compromise the balance of the entire home. In this case, it is imperative to act quickly by calling on an expert before their size is counted in centimeters!
Cracks in masonry should be monitored as they can become dangerous or conceal a more serious underlying problem. Even seemingly small cracks can indicate structural issues that have yet to surface, so it’s important to be aware of their development and take action if necessary.
A crack can be considered a passive crack if they do not get worse over time. These cracks are often part of a home’s natural aging process and are therefore minor. To repair a passive crack, a simple filling should do the trick.
An active fissure may be more difficult to treat. If the crack deteriorates over time, it is important to call a professional. This expert can identify the source of the problem and take steps to resolve it. Often, active cracks are due to freezing, poor drainage, or ground subsidence.
Epoxy is a type of glue that can be used to seal the crack. However, due to its rigidity, it may not remain effective if the house continues to move, which may result in a new crack appearing near the original location.
Polyurethane is characterized by greater flexibility than epoxy and offers hydrophilic properties, reacting with water to form a control seal. This process injects the polyurethane into the crack with a hydraulic pump, which ensures that the polyurethane penetrates deep into the crack.
