Simply defined as concrete spraying system, shotcrete is a very important repair technique for reinforced concrete buildings and METEL brought this system in Turkish construction industry 20 years ago. Being an indispensable concreting technique from erosion prevention works to blast furnace refractory industry, from repair works to build difficult shaped pools and tunnel coating works and in numerous other fields, shotcrete is the first solution that comes to minds of professionals in construction industry in hard times. A repair system to make almost everything have the original values is not very expensive and does not require very difficult applications with existing systems. A burned building, a facility exposed to industrial loads, a pier or a dock heavily affected by sea, a dam exposed to heavy loads, chimneys or cooling towers affected by high temperatures and corrosive gases, bridges, silos, all buildings exposed to heavier loads than they were designed for can benefit from shotcrete application’s feature which creates a monolithic structure by wholly combining with the old reinforced concrete.
