PART 1: CONSOLIDATION WOODEN STRUCTURES
Diagnostic investigation of the cognitive static situation of the heads of the beams and wood trusses to support in the masonry through execution of a small opening in the breach of the wall to the left of the header and execution of micro perforations in depth, executed through the use of special twist drills. The resistance to penetration and the observation of the chips taken outside will give the technician the exact position of the head to the support in the masonry.
INVESTIGATION WITH DIAGNOSTIC EQUIPMENT
Execution of diagnostic investigation of cognitive state of deterioration of wooden trusses of the roof is the support in the masonry and in the struts and chains. The investigation will involve endoscopic tests, ultrasound and resist graphic of wooden structures that will give a complete picture of the static situation.

CONSOLIDATION OF FALSE CEILING IN LATH – INTEGRATIONS OF HOOPS, AND BEAMS
Implementation of accurate cleaning with elimination of rubble and dust suction existing at the extrados of the false ceiling after adequate training of boardwalks and walkways with planks of wood resting on the supporting structure. Checking the status of conservation of wooden structures that make up the warping of support of the false ceiling. Implementation of the hang-up of the plaster in hurdles to the wooden beams of support through application of epoxy primer EPOXYRESIN LPL and formation of a triangle of dough of epoxy resin ANCOR400ECT located between the beam and plaster in the entire length of the ribs on one side only
Integration of hoops, and wooden beams deteriorated, with new elements in seasoned wood is shaped to size, anchored by through bolting and anchor with epoxy resin.
Part 2: CONSOLIDATION MASONRY STRUCTURES AND STONE COMPOSITE FIBERS/RESINS
CONSOLIDATION OF PILLARS IN MASONRY WITH FABRIC FRP
Consolidation of pillars in mixed masonry bricks/stones, through the following steps:
– Washing of the surfaces and formation of plaster to crude with shot Crete structural based natural lime or similar, taking the corners rounded.
– Application of fabric in CFRP (Carbon Fiber) in weight and shape as per design calculation anchored to the structure by epoxy resins with cycle application as per the attached form. The fabric will be applied over the entire surface of the pillar to form a full dressing of the same.

CONSOLIDATION OF MASONRY OR WITH INJECTIONS
Consolidation of masonry or brick vaults that have diffuse lesions and considerable degradation static by injection of consolidating mixture specification based on natural hydraulic lime low content of water soluble salts with chemical and physical characteristics perfectly compatible with the mortars ancient present in face walls.
The injected mixture will occlude large part of the voids present in the masonry structure, giving cohesion between the elements and stillness to the masonry.
Phases of the intervention:
– Execution of perforations dia. 16 Mm, placed in the lime mortar, with 30 cm distance to a depth sufficient to affect the entire thickness of the masonry.
– Insertion of tube injectors, in both holes and along the lesions.
– Formation of raw plaster containment and injection pressure controlled by a mixture of natural hydraulic lime low content of water soluble salts, until refusal, after internal wetting of the masonry.
Performing chemical barrier against moisture rising through the formation of a row of perforations dia. 14 MM with a distance of about 18 cm to a depth of 3/4 the thickness of the masonry is at a height of 10 cm from the level floor. Insertion and plugging of tube injectors, formation of raw plaster containment in lime mortar and injection pressure controlled formulation base of siloxane polymers in a solvent phase WET SHIELD, Until the complete imbibitions of the masonry.
The injected product, reacts with the moisture content of the support by forming a film highly water-repellent that saturating the porosity and the capillaries of the masonry, inhibits the absorption, completely eliminating the rise in the water from the foundations or from the ground, whilst allowing the support full breathability.
N.B. It is recommended that you complete the intervention with application to a height of at least 1.20 ml of plaster dehumidifying macro-based porous natural hydraulic lime, including treatment antisalino. The whitewashing finals must be carried out with breathable paint.
The intervention described above remains stable over time, the signed CORES Srl ensures the effectiveness of the same for at least ten years from intervening where necessary to restore its effectiveness.
