The coating with mortar of the masonry reinforcement is a fundamental requirement to ensure the protection of the steel from corrosion.
Therefore, when it comes to getting this benefit, the conditions of coating have different importance according to the finishing of the masonry reinforcement. However, the coating is also an essential requirement for the proper transmission of forces of adhesion in the overlap areas and this is common for all the masonry reinforcements with structural use, independently of the type of finish.
In order to achieve this provision, you must respect the minimum thickness of coating, both upper and lower, as well as lateral. Side coating in the areas of overlap is essential so that there is the transmission of efforts between the piece of reinforcement and the adjoining one, this circumstance must be taken into account when choosing the width of the reinforcement so that it is appropriate to the thickness of the wall.
If the reinforcement does not have a specific design for the overlap, you must limit your width to allow the correct covering along the reinforcement longitudinally.
