Utilização da técnica de permeation grouting para solução de recalques diferenciais em edificações

Abstract

Failures in projects caused by a lack of efficiency on its execution and maintenance might lead to a variety of pathologies, including the highly common appearance of fissures. Considering that to be a visual issue, the feeling of uneasiness might evoque from its user and turns the pathology into something more noticeable. The differential settlement of structures can be mentioned as one of the main reasons for the emergence of fissures. Considering this context, it is essential to take action regarding the correct diagnosis methods and the problems resolution. The research emphasize the Permeation Grouting technic as a solver for fissures caused by differential settlement a making use of a method consisted by the injection of mortar in the soil, leading to its stabilization and avoiding slipping movements that might be responsible for differential settlements. The theoretic basis englobes the thematic and it is complemented by two study cases of structures with fissures, where the issues were solved by the Permeation Grouting technic, with successful results, proving its practicality, low cost and reliability of use. In addition, executive manner of recovering other components of the structure are also mentioned, like masonry.
