When the CAUSE of the cracks or a basement wall bowing inward is in part or all due to expansive/clay soils then....here is what OTHERS tell you to do
Fairfax County Virginia,scroll down to ---BASEMENT WALLS http://www.fairfaxcounty.gov/DPWES/publications/marineclay.htm
-Cause,Resolution
THEY say, "Depending on the extent of damage,foundation walls MAY need to be replaced while OTHERS can be repaired.To PREVENT FUTURE damage,the clay MUST be REMOVED and REPLACED with sandy or gravelly soils" ......and waterproofed on the outside!

Pic 1. Lateral pressure CAUSING typical 45 degree stair step crack in block basement wall
Pic 2. Lateral pressure causing vertical mid span crack
Pic 3. Lateral pressure causing top of basement wall to bow inward 9 inches.Pilasters FAILED to BRACE wall.
Carbon straps etc on the inside do not remove exterior weight/pressure against the wall,doesn`t relieve any weight/pressure and inside systems do not repair/waterproof EXTERIOR cracks in block walls.And sometimes there are OTHER weights/pressure against the outside of the wall such as, underground ROOTS or a porch footing or concrete slabs.
Underground ROOT that CAUSED exterior cracks in block wall which then allowed water to enter the basement. http://www2.snapfish.com/slideshow/AlbumID=288770686/PictureID=6952552252/a=122238283_111847456

Carbon Fiber is a fabric material when combined with a resin forms a solid structure. I have personal use with the product but not in a foundation application. It seems a bit overkill to introduce such an expensive product to be used below grade. The resin is the key to the success and longevity, not so much the carbon fiber. You can put the same resin on burlap and get similar results. While carbon fiber has great structural properties, it's not exactly known for use as a membrane. Also, any areas not saturated by the resin will be subject to de-lamination.
They can state or claim the product is fantastic in theory, but do they have any homes with this procedure done over 10 years ago?
Carbon fiber is a wonderful product for certain application.
All resins break down over time, if they state theirs does not, ask to get the MSDS sheet on the resin they use and send it to me. I will break down the components and let you know.
