REHABILITATION FOUNDATION IN BUILDINGS

PATHOLOGY OF FOUNDATIONS

Multiple pathologies are appearing in building structures due to problems arising in the foundation. Such FOUNDATION IN BUILDINGS serious damage, ultimately, lead to structural collapse of the building, that is, to lower the resistance of a structure or structural element, internal or external conditions, causing the incapacidadpara desempear function, loss Stability and destruction. These structural collapses caused not only property damage but also human lives sometimes.


Foundations pathologies include possible pathologies that affect older buildings which have rehabilitation costs and which have greater social impact because they involve in most cases the inability commonly used building while often affect the surrounding buildings. That is why the pathologies of foundations require an urgent and thorough pathological study of the underlying causes and the implementation of the actions necessary to address rehabilitation and rehabilitate them and eliminate its effects.

There are various causes that give rise to pathologies in the foundation, distinguishing between intrinsic causes, ie, those pathologies result of the interaction between the soil and the foundation own FOUNDATION IN BUILDINGS and extrinsic causes, or what is the same, the pathologies in the foundation caused by human activities that result in changes in both the building and the environment and thus modify the conditions under which it was designed and planned the building. They are among the first project defects and defects of execution and, among the latter, changes in project assumptions or environmental conditions.

The main defects of the project that could lead to pathologies in the foundation are: lack of capacity, insufficient knowledge of the soil, geotechnical underestimation of risk or defects in the assessment of the land. tre execution defects are: incorrect assessment of resistant strata, staking errors, poor quality of materials, material degradation, errors in the placement of armor, or poorly executed deep foundations. To avoid all these constructive FOUNDATION IN BUILDINGS types, remember the importance of a correct analysis of the project and the permanent control in the execution of the works.

Among the most common causes of extrinsic pathologies in the foundation they are: increasing the number of floors above ground, need to deepen FOUNDATION IN BUILDINGS all or part of the structure to win industrial basements or pits, vaults, etc. Increments live load, and sliding instability phenomena by undercut, trailers, erosions and changes in moisture content and the water table.
