Within the last 20 years, Textile Reinforced Mortars (TRM) have gradually spread as innovative strengthening techniques for the seismic protection of existing masonry buildings. They combine an inorganic mortar layer, applied on the masonry surface, with a high tensile resistant, un-corrosive, fiber-based reinforcement. The paper traces the main steps of a deep research route on a specific TRM technique, called Composite Reinforced Mortar, providing an overview on the experimental testing and numerical modeling experiences aimed at achieving an in-depth knowledge on its behavior and on its effectiveness in improving the masonry performances. It is an example of a systematic approach to research, which deals with the complexity and multiplicity of aspects that need to be considered by the professional designer when choosing among the solutions available on the market
