    2.1 Field of application

    The new concrete layer is usually poured directly or applied as shotcrete. Its function is to increase the deflected cross-sectional area of the concrete element (by increasing the compressive and tensile strength zones under bending loads), depending on the application and placement of this additional layer of concrete.

    Please note that before the new concrete covering is laid, the surface to be covered with the old reinforced concrete element must be prepared by appropriate means and pre-wetted to ensure proper installation (see following chapters for more details).
