Corrosion of reinforcement is an essential factor that limits lifetime of reinforced concrete structures. The parts of bridges, tunnels and parking decks that are frequently exposed to deicing salts are especially vulnerable.

The installation of GFRP-rebars is a possible solution to this problem. Due to high strength and stiffness and excellent durability a new GFRP-reinforcement system allows high design strength and high moment capacity of the structure. The bond behavior matches that of conventional steel reinforcement.

Applications in civil engineering and building construction are reviewed. The focus lies on the installation in areas of diaphragm walls that are to be cut by tunnel boring machines.

Schock is well known for structural thermal insulation elements for balconies. GFRP shows high strength and low thermal conductivity. This is the reason why the research and development is focussed on GFRP-rebars since 1995. The newly developed element ComBAR® is a unidirectional E-CR glass fibre reinforced polymer (GFRP) reinforcement. It is easily cut and machined. As a
