2. Concrete protection
2.1 Product features – Surface protection systems
When the steel coating is too porous and/or of insufficient thickness, or when the environment is particularly aggressive, it is often necessary to apply a concrete protection treatment. Such protection can also be applied after a repair to protect not only the repair itself, but also the rest of the structure.
For a given use, these products and product systems must satisfy one or more of the following functions:
-
protection of concrete against penetration :
of gases (especially carbon dioxide, responsible for carbonation), measured by gas permeability,
of water vapour, measured by water vapour...
