CONSOLIDATION THROUGH MASONRY STRUCTURAL INSERTION USING INJECTIONS

This technique, born in the Fifties, in order to consolidate soils in foundation or rocks, has been adopted for reconsolidating masonry damaged by earthquakes and it is now widely used to heal degradation. Possible causes can be earthquakes or vibrations due to traffic, failure in the foundation, placer mining of materials caused by rain or water infiltration. The advantage of this technique is to be minimally invasive from a visual point of view because it does not alter the aesthetic appearance of the structure. The intervention consists in creating in the masonry to be reconsolidated a series of downwards-inclined holes which should be deep two-thirds of the thickness of the wall. Then the binder material is injected with a special machine consisting of a pump. The inserted material will form a single body with the stone material present inside.
