Powder preparation, ready-to-use, based on hydraulic lime, for the preparation, with the sole addition of water, of grout for masonry reinforcement, injectable and castable, high performance in terms of sliding, strength and stability, for ecological building interventions and the restoration of vintage buildings and monuments. In the Sanafluens mixtures, the water is completely and stably incorporated from the hydration reaction of lime; conversely, in traditional mixtures, a very high part of added water, is free, and evapourating, it leaves gaps in the walls. Sanafluens is based on natural hydraulic lime, sodium gluconate, kaolin, aluminates; it does not contain cement, resins, solvents and radioemissive aggregates. Consolidation through injections of brick, stone or mixed masonry, "bag" structures, masonry damaged by the earthquake. Consolidation of masonry affected by capillary rising damp and soluble salts. Consolidation of plasters detached from the masonry support, even with frescoes or of historical and artistic value. Consolidation of foundation structures, pillars, vaults and arches. Clean the application surfaces by spraying abundantly with water. If there is a lack of plaster, apply a suitable render of hydraulic lime and sand (such as Untersana) to close as much as possible the escape routes of the grout once it has been injected. Trace, from bottom to top and from left to right, a 50 cm square grid. On the intersection of the squares, drill the masonry with a rotary drill, with a bit of suitable diameter (depending on the type of masonry to be injected; diameter usually between 12 and 24 mm), to a depth of at least 3/5 of its thickness, tilting the drill downwards by about 10 - 20°. Once all the holes have been drilled, they will be sucked up, blown with compressed air and sprayed with water, to remove the dust inside them produced by the drilling. Insert in the holes for a depth of about 5 cm, transparent meshed rubber tubes, with a total length of at least 30 cm (therefore with about 25 cm external). Properly seal the perimeter of the pipe with Anchorsana Fix accelerated setting grouting mortar to prevent the injected product from escaping. Inject the grout always keeping it lightly mixed and operating a continuous flow, without interruptions. Pour about 2/3 of the mixing water into the mixer. Gradually add Sanafluens and the water still required, continue to mix until a fluid, homogeneous, lump-free grout of the desired consistency is obtained. The mixing water indicatively necessary is equal to 22-24% by weight (5.5 - 6 litres per bag). Reinforcing backfills and fills can be carried out both by gravity and using manual or automatic pumps, depending on the type of application. To verify the effectiveness of the reinforcement, the grout will come out of the pipes adjacent to that in which it is injected. Approximately 1500 kg of Sanafluens for each cubic metre of volume to be filled.
