There are several problems with carbon fiber plates. The main issue is carbon fiber plates do not secure to the sill plate or the floor where the major problem areas occur. Due to the lack of top and bottom attachments, the outside ground pressure shifts to the top and bottom of the foundation wall and makes the wall move as one unit resulting in a total failure. The wall shears at the cove, where the wall meets the floor. It is a disastrous situation. In the event this happens, it is possible the whole basement may need to be rebuilt.
The other problem is that fiber plates are pre-impregnated with an epoxy resin. This makes the product very rigid and straight. You will most likely be working with a bowed or deflected surface so a rigid product is going to be have a harder time bonding to the work surface. In addition, epoxy has a difficult time adhering to other epoxies. Since the plates are already pre-impregnated with epoxy, the bond is only as good as the bond between epoxies. It doesn’t have a chance to bond the carbon fiber to the foundation wall. This causes the carbon fiber plate to delaminate with time, requiring additional work in the future. If the contractor has to come back after a failed carbon fiber plate install, the damage done to the wall is commonly worse than at the time when the wall was originally repaired.
