part of Gallura&#8217;s architectural heritage. However, many of these structures today present major structural problems due to the age of the building, the characteristics of the foundations, and ground movement. <\/p><p>One of the most common problems found in historic granite or &#8220;sack&#8221; masonry buildings is the appearance of very noticeable cracks, especially at the corners of the building.<\/p><p>Understanding the origin of these injuries is crucial to choosing the correct consolidation work, avoiding unnecessary or even damaging work.<\/p><h2>Why cracks appear in old stone houses<\/h2><p>In most cases, cracks that develop in the corners of buildings result from differential foundation failure.<\/p><p>Ancient Gallura dwellings were often built without true concrete foundations. The masonry rested directly on rubble or on simple enlargements of the wall base, adapted to the natural terrain. <\/p><p>Over time, they may occur:<\/p><ul><li><p>land subsidence;<\/p><\/li><li><p>Moisture variations in the subsurface;<\/p><\/li><li><p>Erosion caused by stormwater;<\/p><\/li><li><p>Loss of consistency of old mortars;<\/p><\/li><li><p>Differential movements between different portions of the building.<\/p><\/li><\/ul><p>When one part of the structure yields more than the other, stresses are generated that cause cracks and fissures to open.<\/p><h2>&#8220;Sack&#8221; masonry: an ancient but delicate technique<\/h2><p>Many old houses in Gallura are made of so-called &#8220;sack&#8221; masonry.<\/p><p>This construction technique included:<\/p><ul><li><p>Two exterior stone facings;<\/p><\/li><li><p>An inner part filled with smaller stones, soil and mortar.<\/p><\/li><\/ul><p>These masonries have high mass and good thermal inertia, but they are particularly sensitive to ground movement and water infiltration.<\/p><p>When masonry loses internal cohesion or foundations fail, they may appear:<\/p><ul><li><p>Diagonal injuries;<\/p><\/li><li><p>bulges;<\/p><\/li><li><p>Out-of-plumb of the walls;<\/p><\/li><li><p>Detachments between orthogonal masonry;<\/p><\/li><li><p>Roof deformations.<\/p><\/li><\/ul><h2>Less invasive interventions: consolidate without demolishing<\/h2><p>Not all buildings require heavy intervention. In many cases it is possible to improve structural stability with less invasive techniques that preserve as much of the original structure as possible. <\/p><h3>Injections of consolidating mortar<\/h3><p>One of the most widely used techniques is to perform injections of fluid lime-based mortars inside masonry.<\/p><p>This intervention makes it possible to:<\/p><ul><li><p>filling internal voids;<\/p><\/li><li><p>Improve the compactness of masonry;<\/p><\/li><li><p>Increase collaboration between stones;<\/p><\/li><li><p>Reduce the risk of further detachments.<\/p><\/li><\/ul><p>It is a particularly suitable solution in historic buildings where the utmost authenticity of construction is to be maintained.<\/p><h3>Reinforced crack seams<\/h3><p>When lesions are localized, reinforced seams can be used to intervene.<\/p><p>This technique involves the insertion of stainless steel bars or composite materials within the masonry, embedded in compatible structural mortars.<\/p><p>Seams make it possible to:<\/p><ul><li><p>Reestablish the continuity of the wall;<\/p><\/li><li><p>Limiting the opening of cracks;<\/p><\/li><li><p>Improve local structural behavior.<\/p><\/li><\/ul><h3>Metal tie rods<\/h3><p>In some cases, metal tie rods are installed to connect opposite walls of the building together.<\/p><p>This solution was used in ancient times and allows for:<\/p><ul><li><p>counteracting the thrusts;<\/p><\/li><li><p>Improve the boxy behavior of the building;<\/p><\/li><li><p>Limit wall clearance.<\/p><\/li><\/ul><h3>Micropiles and soil consolidation<\/h3><p>When the problem stems primarily from ground subsidence, less invasive foundation consolidation techniques than complete foundation reconstruction can be used.<\/p><p>These include:<\/p><ul><li><p>micropiles;<\/p><\/li><li><p>expanding resins;<\/p><\/li><li><p>Localized soil consolidations.<\/p><\/li><\/ul><p>Micropiles allow loads to be transferred to deeper, more stable soil layers, limiting further subsidence.<\/p><h2>The most invasive but most effective interventions<\/h2><p>In more severe cases, especially when the failure is significant or the structure has obvious deformations, more invasive structural interventions may be necessary.<\/p><p>This work is often essential in historic buildings where complete demolition is not possible.<\/p><h2>Concrete foundation refurbishment<\/h2><p>One of the most effective techniques is to build new reinforced concrete foundations under existing masonry.<\/p><p>The work is done by digging under the masonry in small, alternating portions to preserve the stability of the building during the work.<\/p><p>Next we proceed with:<\/p><ul><li><p>Reinforcement of the new portions;<\/p><\/li><li><p>Concrete pouring;<\/p><\/li><li><p>Progressive linkage of the various sections.<\/p><\/li><\/ul><p>This method makes it possible to significantly consolidate the structural base of the building.<\/p><h2>Construction of a concrete summit curb<\/h2><p>Another widely used intervention in historic stone buildings is to construct a concrete curb around the entire perimeter of the masonry.<\/p><p>The curb has the function of:<\/p><ul><li><p>Connect all walls together;<\/p><\/li><li><p>Improve the structural behavior of the building;<\/p><\/li><li><p>Better distribute roof shares;<\/p><\/li><li><p>Increase the resistance to horizontal movements.<\/p><\/li><\/ul><p>To perform this type of work, it is generally necessary to completely dismantle the existing roof.<\/p><p>Subsequently:<\/p><ol><li><p>you make the curb following the profile of the masonry;<\/p><\/li><li><p>is still structurally to the existing walls;<\/p><\/li><li><p>you reinstall the roof over the new consolidated structure.<\/p><\/li><\/ol><p>This type of workmanship is particularly suitable in historic buildings that are to be fully restored without demolition and reconstruction.<\/p><h2>Each historic building needs a specific analysis<\/h2><p>Old Gallura houses cannot be treated with standard solutions.<\/p><p>Each stazzo possesses different construction characteristics related to:<\/p><ul><li><p>type of stone;<\/p><\/li><li><p>quality of mortars;<\/p><\/li><li><p>ground conditions;<\/p><\/li><li><p>Presence of moisture;<\/p><\/li><li><p>Changes made over time;<\/p><\/li><li><p>State of preservation of the roofs.<\/p><\/li><\/ul><p>Therefore, it is essential to perform a proper structural analysis before choosing any intervention.<\/p><p>In fact, a consolidation performed without understanding the real cause of the cracks risks not solving the problem or even aggravating it over time.<\/p><p>Recovering a granite stazzo means preserving the building history of Gallura while improving its safety, durability and architectural value.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div
