Textile Reinforced Cementitious (TRC) composites have gained recent ttention due to several advantages compared to traditional steel-reinforced concrete, such as concrete usage reductions and design freedom. The mplementation of this technology on a sandwich design offers light-weight nd slender structural elements with superior mechanical performance. espite their advantages, they exhibit a complicated structural and fracture attern rendering their monitoring essential, as only detailed information on the damage modes will lead to understanding their failure behaviour. This review paper reports on NDTs{\textquoteright} application, working principle and configuration, performance and accuracy. Potential future lines of research and advances are discussed.
