Difficulties in Operation of Elevations in Large-Panel Buildings

Abstract

The article presents problems in facade walls operation of large-panel buildings. Examples of irregularities resulting from the initial poor quality of precast elements and assembly errors are presented, as well as problems arising as a result of repeated renovation and modernization works. The problems before and after wall insulation were discussed in greater detail, resulting from leaking joints of precast elements. Biological threats resulting from the influence of algae, lichens and vines on the façade material are presented. The general technical condition of the facade of a selected group of buildings was compared in studies carried out at an interval of 11 years.
