For temporary reinforcement of diaphragm walls the section of a reinforcement cage which will be cut away by a TBM must be reinforced by mixed cages combined with steelen upper and lower sections and a medium center part on base of FRP. These sections called soft eyes are important for time and cost efective heading of TBMs. So world wide this method becomes accepted more and more.

Straight rebars and lots of bended FiReP^® FRP elements will be assembled to the center part of such a case.
High strength and high E-Modulus are important properties beneath cuttability.

Each individual design must be planned carefully that bending companies and job site staff are able to handle materials and cages well.

Reinforcement of slabs beams and colums are the basic cases of application and here the special reinforcement of concrete plates on an airfield – especially in front of a hangar are of interest. Due to the necessity of a non magnetic section – called swing place – a position for planes to adjust the electronic equipment – FiReP^® -FRP reinforcement and all bended parts and all connectors, spacers etc must be free vom steel completelx. without any exception.

The annual cost of repair and maintenance of the European infrastructure, as a results of problems associated with corrosion, is around 30 Billion EURO and the repair costs can be twice as high as the original ones. corrosion in steel rebars leads directly to damage of the concrete itself, significantly reducing the quality of life in the built environment. ( CurvedNFR-EUREKA -2002 )

And furthermore, we must remember that steel corrosion can be cause of increase of CO2 Emission and will influence on the natural environment.

FiReP^® -Rebar can offer environment friendly solution and propose significant repair and maintenance cost reduction.
