Carbon fiber laminate is one of the ways that they retrofit elevated concrete slabs that are found too weak for (1) modern earthquake design codes and, (2) anti-terrorism blast protection.
They are adding a high tension element below a compression strength element. Almost like post-tensioned cable.

The front wall of my 60 plus year old basement had an open crack the whole length. I contacted an engineering group that advertised Carbon fiber bands like I had seen in an old episode of "This Old House." They installed the six inch wide bands about every ten feet anchored to the basement floor and the rim joists. I covered the rough edges of the bands with Lexel, filled the crack with cement, painted the wall with Drylok and then regular finish paint.
The episode of "This Old House" had Bob Vila showing an old Massachusetts tavern that was restored with a two story wall strengthened with Carbon Fiber vertical bands. That was way back when.
