In one of our previous renovation-addition project, we had cracked and bowed foundation walls in the basement, after lots of conversation and discussions with my senior structural engineer, he explained to me about reasons of these problems that may happen in basement walls;
A) Crack : These are usually warning signs about foundation walls, when poured/concrete block crack either from settlement or the expansion and or contraction of concrete.
B) Bowed Walls: After a while, poured/concrete block foundation walls may start buckling under outside (soil) pressure. So, after consulting with with experts, as a solution for both of these problems, we ended up to use Carbon Fiber Strips; They are like wall anchors and designed to work on both concrete/ concrete block foundation walls. As benefits of this material I can say these items :
After necessary arrangements with their company to install these fibers, we prepared the job site for them, they came and finish the job really professional, quick and nice. To me, it was really reasonable solution for this issue.
