If the entire structure of a house is important, its foundation is important in a very special way. Indeed, it is it that supports the entire building and guarantees its sustainability. Therefore, it is essential to maintain the foundation of your house in good condition. So, when should cracks in the foundation of a house be repaired? It is to this question that Groupe Fissure Expert will answer here.
Repair the foundation in case of appearance of obvious cracks
When you notice slits in the foundation of your house, you should know that the structure of it is already affected. There are several kinds of cracks due to their lengths and widths. Here are the classes of cracks that are often encountered:
- Microcracks: very superficial, they have a width of less than 0.2 mm. Often, they are not dangerous. However, you should have them inspected to ensure that they are not a sign that the foundation structure is affected. Indeed, very often, the crack seems tiny because it has closed due to the weight of the house. If it is a structural microcrack, then repairs to the foundation are required.
- Fine cracks: they have a width of between 0.2 and 2 mm. They are also considered benign. However, their evolution or multiplication is a sign that the structure of the foundation of the house is damaged. Although thin, an inner or outer crackcan be structural. You must without further delay call on groupe Fissure Expert for an assessment of the situation and also for the execution of any work.
- Deep cracks: as the name already suggests, these are dangerous cracks. They have widths greater than 2 mm. As for their length, it is more than 20 cm. Faced with such breaches, the only thing to do is to carry out deep and professional renovation work. If your residence is in Montreal, call us.
Whether it is a benign interior or exterior crackor not, the best thing to do is to carry out a careful inspection and then renovations if necessary.
Repair the house foundation in case of water infiltration
There are many signs that reveal the presence of cracks in the foundation of a house. One of them is water infiltration . Lizards in a foundation are the large and slow entry of water into a house. Generally, these cracks are hidden by walls; which does not allow to see them.
In case of water infiltration, you must carry out decontamination work. The reason is that the water may have damaged the basement. This does not guarantee the solidity of the whole house. After decontamination, you need to renovate the area affected by infiltration. If you have home insurance, it is possible that the renovation work is covered by the insurer.

In such a situation, you must use professionals like us. We will first proceed to the removal of objects contaminated by mold. Then we will move on to the decontamination of the concrete.
It is essential to decontaminate the concrete before refurbishing everything. The reason is that by leaving the mold in place, it will infect the new materials to be installed. Worse, mold is dangerous to the health of everyone who will breathe the contaminated air in the house. Once the decontamination is complete, repair work on the foundation crack can begin.

Regardless of the cause of the subsidence, it will cause cracks in the structure of the foundation to appear. Repairs must therefore be made.
