What is the Sistema REFC?<\/strong><\/h1>\n\n\n\n

REFC technology is the most cost-effective and innovative solution for the strengthening and restoration of infrastructure in the world. It not only repairs degraded structures; it actually makes them stronger than when they were new. <\/p>\n\n\n\n

Our Material<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The main component of the Sistema REFC is carbon fiber. The fibers are woven into a flexible fabric that adheres to the surface of the framework to be repaired by wetting it with a structural epoxy resin formulation. <\/p>\n\n\n\n

\"\"<\/figure>
\n

The Sistema REFC provides the most suitable balance of properties to reinforce and \/ or repair damaged concrete structures. <\/p>\n\n\n\n

The low viscosity and thixotropic nature allows rapid and complete wetting of carbon fiber fabrics without drainage or sagging on vertical and raised surfaces. <\/p>\n\n\n\n

The pot life and cure speed of the material is balanced to allow multiple applications or coats in a single day. <\/p>\n<\/div><\/div>\n\n\n\n

      Types of strengthening<\/p>\n\n\n\n

      COLUMN REINFORCEMENT<\/span><\/strong><\/h1>\n\n\n\n

      REFC is used to increase the ductility and strength of concrete columns. Due to the benefits of confinement effects, the ductility of the columns is significantly increased.<\/p>\n\n\n\n

      In addition, the REFC System helps compensate for inadequate amounts of lateral ties, or improperly detailed, and significantly increases the shear strength of the columns.<\/p>\n\n\n\n

        BEAM REINFORCEMENT<\/span><\/strong><\/h1>\n\n\n\n

        The Sistema REFC increases the bending and shear resistance of concrete beams.<\/p>\n\n\n\n

        To increase flexural strength, the fabric is attached to the tension face. And for shear strength, the fabric is attached to the beam web.<\/p>\n\n\n\n

        It can also be used to increase and repair cracked steel beams. Beams cracked and then repaired with the Sistema REFC prove to be stronger than the original beams without damage.<\/p>\n\n\n\n

          CONCRETE FLOOR AND WALL REINFORCEMENT<\/span><\/strong><\/h1>\n\n\n\n

          The Sistema REFC significantly increases forces on wall and floor surfaces, interior and exterior in concrete buildings.<\/p>\n\n\n\n

          It is very light and is applied to these types of structures in a way very similar to a surface coating, but at the same time it will provide significant strength as if sprayed concrete had been applied to the structure.<\/p>\n\n\n\n

            REINFORCEMENT OF CONCRETE SLABS<\/span><\/strong><\/h1>\n\n\n\n

            The REFC fabric is attached to the bottom of the slabs (positive moment regions) or to the top of the slabs (negative moment regions) to increase flexural strength.<\/p>\n\n\n\n

              REINFORCEMENT OF TANKS AND PIPES<\/span><\/h1>\n\n\n\n

              One of the most economical and effective applications of the Sistema REFC is in the strengthening of buried pipes. Concrete and steel pipes can be strengthened to withstand even greater pressures than originally designed, at a fraction of the cost and time of other alternatives.<\/p>\n\n\n\n

              In the case of pipes with a diameter greater than 1 meter, access is made from the manholes and all operations are carried out from the inside.<\/p>\n\n\n\n

              If the pipe is not buried, the coating can be done on the outside of the pipe, resulting in the same benefits.<\/p>\n\n\n\n

              Corroded or leaking steel pipe can be fortified with REFC to compensate for loss of wall thickness due to corrosion.<\/p>\n\n\n\n

              This application also makes the pipe waterproof and prevents leaks. Steel pipes can be lined to withstand higher pressures than originally designed.<\/p>\n\n\n\n
