Réparations de béton

Concrete is all around us.  Over time, chemical changes provoked by carbon in ambient air, chloride contamination, freeze and thaw cycles strain concrete structures.  Our experts take the necessary actions in order to quickly rectify the situation to ensure the longevity and security of the structural concrete elements.


Concrete is subject to many external stresses that can create cracks, such as freezing and thawing cycles and soil movement among many others. While concrete cracks appear to be typical, it is not recommended that they remain ignored. We stabilize, waterproof and repair to restore the structural integrity of the concrete element in question.
