Did you know?

The foundation of your home is just as important as the roof that protects it. Unfortunately, cracks in concrete foundations can be found in almost all homes. They can appear in the foundation walls, the corners, the floors, and the corners of the windows.

Regardless of the severity of the crack in the foundation, as soon as it is discovered, it is important to contact S.O.S. Fissures Outaouais. Our team will conduct a thorough inspection of the cracks and offer a guaranteed solution. No crack or leak should be left unrepaired. The preservation and durability of the structure of your home—and its foundation in particular—are of the utmost importance.

What are the causes of cracks in concrete foundations?

The Canadian climate, the extreme temperature deviations that we experience each year, and various environmental factors such as rain, trees, groundwater, and ground movement are among the leading causes of the appearance of cracks in the walls or foundation of a house. Other causes may also come from the construction of the foundation itself, the age of the property, and the quality of the materials used.

Although some cracks may not seem serious with respect to the structure of your home, other cracks may have more significant consequences, starting with the thermal insulation, which can quickly raise the price of your bills! There is also water seepage to consider, which—in the medium to long term—can weaken the structure of your home and cause irreparable damage. Normal wear and tear can certainly occur in the concrete foundation after a few years. This can lose its watertightness and impermeability over the years, which can cause cracks in the concrete and water seepage.

Are you in doubt? If you notice such signs, you should act without waiting too long, because the consequences can really damage your home. Contact our team of crack repair experts.
