Masonry work does not last forever and periodically requires extraordinary maintenance. The need to perform extraordinary maintenance work on the flooring of terraces and balconies is due to the fact that the reinforced concrete structures and superstructures (screed and flooring) are subject to various kinds of deformation: dynamic, thermic, shrinking, etc. In many cases, this deformation also leads to the structure losing its impermeability or to the used elements disintegrating (tiles coming loose, screed crumbling, etc.). IT IS NOW POSSIBLE TO DO WORK DIRECTLY ON THE EXISTING FLOORING WITH LARIX TERRACE. It is recommended to consult the Laribit technical department to be able to design the optimal application of the LARIX TERRACE system in various types and sizes of terraces and balconies.
