The clearing has nothing to do with the excavation since it involves removing different parts of a building, while retaining its envelope.
This practice is commonly used in the renovation of an old building classified as a historical monument. The clearing allows to preserve the original character of the frame. It is an art that requires precise qualifications.
Study of the nature of the soil
During demolition, the expert will establish a study of the composition of the soil, but also of the surrounding trees whose roots could damage the foundations. This is an essential step for the stability of the structure.
Diagnosis of foundations
Before partially clearing, a foundation expert analyzes the condition of the foundations and foundations so as not to touch the existing one and not destabilize the entire structure of the building that will remain in place.
A misstep or mishandling can result in the total and irremediable loss of the building. This is why only professionals who have the expertise of this type of work have the certifications to intervene.
