Renunciation in below: key elements to understand this process

The recovery of the below is a series of techniques and practices aimed at consolidating the foundations of a building. This procedure is often implemented in order to resolve the settlement or deformation complaints that can lead to dangers for the building and its occupants. Through this article, we offer you an exploration of the different basic methods and some information relating to their cost.

Current methods below

Expansive resin injection

TheExpansive resin injection It is a method of stabilizing the soil constituted in the injection of expansive resins in the cracks and in the present emptiness in the ground and around the bases of the building. For hardening, this resin fills the cracks, improves the density of the soil and slightly raises the damaged structure.

This non -invasive process is particularly suitable for minor complaints and occasional repairs that require few heavy works.

Micropieux reinforcement

Strengthen Micropyle It consists in the installation of low diameter batteries directly under the existing bases. These batteries are therefore fixed to a system of anchoring to provide further support to the structure already underway.

This technique allows you to compensate the lack of lifting the original soil and offers better resistance to vertical, horizontal and wind forces. It is particularly suitable for buildings whose geometry and access are complex and for the bases built on an unstable or not very favorable construction.

Construction of new bases

For more substantial problems, it may be necessary to create new bases in parallel with the existing ones. This generally implies the excavation of the earth and the strengthening of the existing walls before paying these new basics.

If you are taking into consideration this outdoor development, what you need to do is consult the specialists able to evaluate the complexity of the project and guide you throughout the process, taking into account the high cost and the prolonged duration of the job.

When to consider a recovery at the bottom?

The decision to resort to a recovery in an underlying must take into account several factors such as:

• The general state of the building: If it has worrying signs such as significant cracks, relaxation stability problems or visible recurrent, it is necessary to consider a rapid intervention in order to prevent the situation of deterioration more;
• The age of the building: Over time, the materials used during construction can lose their properties and lead to a degradation of the bases. A recovery in the below can therefore be foreseen to preserve the integrity of the building;
• The nature of the soil: Changes in geological or climatic conditions can affect the stability of the soil that supports the structure, making the necessary intervention in the underlying;
• Extension projects: If you plan to add an additional floor or to make a lateral extension of the building, it is often essential to verify the resistance of the existing bases in advance and, if necessary, to consolidate.

At which price to expect for the resumption of the below?

To precisely estimate the cost of the recovery of the below, it is recommended to take into account several elements.

• The chosen method: As mentioned above, techniques such as the resin injection and the strengthening of the micropyle are generally less expensive than the construction of new bases;
• The greatness and complexity of the work: The discreet work or limited to some areas of the structure will be, not surprisingly, less expensive than those that require intervention throughout the building.
• The duration of the site: The more a project takes time, the more costs generate;
• Specific constraints: Depending on the position and conditions of access to the site, some adaptations can be essential and lead to an additional cost.

To obtain a more precise estimate, it is recommended to call several specialized companies and compare their quotes. There price range For a recovery of the below it may vary considerably, in particular due to the factors mentioned above.

However, it can be estimated that a reinforcement from the micropils will cost between 300 and 500 euros for linear meter and that the injection of expansive resin often resists from 100 to 150 euros per square meter.

In this instructive video, immerse yourself in the world of recovery in the underlying with a detailed explanation of techniques and procedures. Discover the key steps to strengthen the structure of the building and solve the foundation problems.

Conclusion

The recovery of the underlying is an essential approach to preserve the integrity of a building whose bases are weakened or insufficient. Thanks to various methods such as the resin injection or the installation of micropils, it is possible to protect and perpetuate the structure by limiting the inconveniences related to work.

Although it is difficult to estimate the total cost of this intervention, the comparison of multiple quotes and the evaluation of specific needs allow to better anticipate the budget to dedicate to this delicate operation.
