Concrete block foundations are very sensitive to freezing and thawing cycles. Over time and under the pressure of the ground, concrete blocks may crumble and break. Considerable progress has been made in terms of the quality and strength of concrete during the last few decades. However, if your home was built in the 1950s, it is likely that some building requirements were not met, such as the consistency of the concrete mixture or its compression strength, explaining the fragility of block foundations.

If you are in doubt about the strength of your foundation or if you have already noticed defects, don’t hesitate to call upon Monsieur Fissure to do a complete diagnosis of your building. We will provide you with a detailed estimate of the concrete block rehabilitation and replacement work that needs to be done.

There are two ways to replace block foundations: raise the building with steel beams and a hydraulic lifting system or shore it up using adjustable posts. In all cases, it’s a very delicate operation involving risks and must be performed by a professional with perfect knowledge of a building’s load transfer system.

It’s a job that must be done with the assistance of an engineer who will study the building plans and determine precisely where to place the beams or the lifting posts.
