and internal cavities; • asonry with the presence of capillary rising damp m and soluble salts. TECHNICAL CHARACTERISTICS Mape-Antique I is a cement-free, fluid hydraulic binder in powder form for injection slurry made from lime, Eco-Pozzolan, natural ultra-fine sand and special additives according to a formulation developed in MAPEI’s research laboratories. When mixed with water in a suitable clean container, Mape-Antique I forms a fluid, volumetrically-stable injection slurry resistant to salts which is easy to inject with a manual or electronic pump or by gravity casting in structures with cracks, gaps or internal cavities. Once hardened, the properties of slurry made using Mape-Antique I, such as mechanical strength, modulus of elasticity and porosity, are very similar to slurry made using lime, lime-pozzolan or hydraulic lime originally used in the construction of old buildings. Compared with these types of slurry, Mape-Antique I also has properties which make the product

resistant to various chemical-physical aggressive phenomena, such as the presence of soluble salts, freeze-thaw cycles and alkali-aggregate reactions. Typical values are shown in the Technical Data table (see Application Data and Final Performance sections) which refer to the main characteristics of Mape-Antique I at both fresh and hardened states. RECOMMENDATIONS • Do not use Mape-Antique I for casting into formwork (use Mape-Antique LC mixed with aggregates with a suitable grain size). • Do not use Mape-Antique I on structures with murals (use Mape-Antique F21). 601_mape-antique i_gb (25.10.2012 - 1ª Bozza/Corr.

e is lower than +5°C. Preparation of Mape-Antique I Filling of the injection pump with Mape-Antique I Consolidating injection with Mape-Antique I APPLICATION PROCEDURE Preparation of the substrate Grout and “seal” all cracks and gaps on the masonry facing wall from where the slurry could seep out. Drill 20-40 mm diameter holes to a depth of 2/3 of the thickness of the wall, preferably at a square pitch of 50x50 cm. If the wall is thicker than 60 cm, it is better to make holes from both sides. Fasten small tubes or injectors in place to inject the slurry. The day before injecting the slurry, we recommend saturating all the inside of the structure with water through the tubes or injectors previously fastened in place. Saturate the wall starting with the holes in the highest position. Make sure the structure has absorbed all the water before injecting the slurry. Preparation of the slurry Prepare Mape-Antique I in a suitable clean container using a low-speed electric drill with a
