Yes I still need help. Local pool company looked at it and believes the walls are defective. There is one other cracked wall and several others which are starting to fails. Its a fort wayne pool may10 years old and apparantly there is some history with this company and defective poly walls. the pool company is checking for available warranty.

Have you ever repaired walls using a stainless steel plates? That may be an option as oposed to a tear out.
