1. Shotcrete
Shotcrete is concrete that is sprayed onto a substrate using a lance and a compressed-air jet. . It is used in structures when concrete casting becomes an impossible or too delicate operation and, in particular, in the following cases:
filling cavities (relining damaged concrete areas, re-coating rebar after stripping);
masonry pointing ;
execution of protective surface layer ;
increase in concrete cross-sectional strength ;
coating of new reinforcement for structural reinforcement ;...
