CONSOLIDATION OF STONE, BRICK, MIXED OR CONCRETE MASONRY THROUGHT THE “SEW – UNSEW” TECHNIQUE

The so-called “sew-unsew” technique consists of the patient work of consolidation of a stone, brick or mixed masonry, by replacing each damaged piece, like a ruined stone or brick. In this way, the masonry will obtain again its consistency and homogeneity lost over the time. This method is used not only for entire masonries or facades, but also for the intrados of the windows, made of stone or brick.
