Used as “structural connection” placed on the inside of old masonry to guarantee a better connection between the substrate (concrete, stone, bricks, wood, etc.) and the strengthening products from the MAPEI FRP and FRG System.

Features & Benefits

• An innovative system for strengthening, static and seismic upgrading of reinforced concrete and masonry structures. Composed by unidirectional carbon fibre threads inside a gauze wrapping which gives it its characteristic “cord” appearance
• Available in diameters of 6, 8, 10 and 12 mm. The basalt fibre “cords” are available in diameters of 10 and 12 mm
• Used in combination with fabrics from the MapeWrap range, Carboplate plates or the Mapegrid mesh in order to improve the anchorage, particularly in flexural and shear strengthening applications
• High tensile strength
• Lightweight
• Resistant to alkaline hydroxides in the concrete
• Resistant to corrosion, including when chlorides or other aggressive substances are present
• Excellent fatigue strength
• Considerable increase of the connection between the reinforcement and the existing substrates
• High durability of materials also in aggressive environments
• MapeWrap FIOCCO eliminates the risks of corrosion when steel is used. Also, thanks to its very low weight, it may be installed very quickly without the use of special lifting, and in many cases, without closing off the structure while in service

Recommendations & Limitations

• Workers must be provided with protective gloves and goggles and anti-solvent safety masks
• After impregnating the end of the cord with MapeWrap 21 and inserting it into the masonry, sprinkle it with dry quartz sand
• The substrate in which the MapeWrap FIOCCO is inserted must be dry, clean, mechanically strong and free of dust
• The temperature during application must be at least 5°C (or 10°C in case MapeWrap Primer 1 is used) and the structure must also be dry and protected from rain and dust carried by the wind
• After completing the application, make sure the treated surfaces are kept at a temperature higher than 5°C (or 10°C in case MapeWrap Primer 1 is used) until the products are completely cured
• Protect the surface from rain for at least 24 hours if the temperature does not drop below 15°C and for at least 3 days if the temperature is lower
