Seismic retrofitting of reinforced concrete structures (brick, stone)

Employing a carbon-fiber external reinforcement system in seismically active areas with 7-9 magnitude levels reduces seismic loads by 1.5-4 times, depending on the structure and site conditions.

Benefits of seismic retrofitting with composite materials 

Seismic retrofitting of buildings using carbon fiber reduces the cost of this type of work by 5-20% compared to traditional methods of seismic reinforcement (concrete reinforced jackets, sprayed concrete, construction of additional reinforced concrete and metal frames, clips, etc.). Price variation depends on the number of floors in the reinforced building, structural elements, seismic area, etc.

Seismic reinforcement with carbon fiber reduces the cost of facility operation, since the minimum service life of this system is 50 years.

The use of carbon fiber allows architects to freely choose planning solutions and provides engineers with a wide range of building design solutions, as well as reducing load on the object. The absence of visible thickening of those building elements reinforced with carbon fiber preserves the existing architectural appearance.

An example of seismic retrofitting of columns reinforced with and without carbon tape:
