This year I have noticed that some section of the pool side boards that look like ply boards have bowed out word and 2 supporting 4x4 in front of the bow look like the have come away at the very bottom of the pool where the metal track is at plus I see stress cracks on the 4x4 in front of the bowing boards will I be able to repair only theses sections and will it be difficult. Is there a special type of board and 4x4 to use when doing this type of repair.
Thank you in advance for your help
