Just got back from looking at it, I think it will restretch ok, certainly does not feel delaminated. Just damn upsetting when it happens as it knocks your confidence.
I noticed that there is a seam running length ways, one side is ok the other is where the ripples are. My personal feeling is that the initial installation was not very good, although when I did the intial survey all seemed fine. Has anyone got any tips to try and avoid this happening again or is it just one of those things.
