I need repairs done to existing floor
Try google. That's what I do when I'm looking for something very specific. Lumber Liquidators maybe?
8 inch flooring? Why so high?
i know of a 7 9/16th wide bamboo floor. It is in an engineered format with a click system. If you are looking for a solid bamboo floor plank this one wont work. If the one you have has a click system, you can get a sample of this one to see if it would click together with what you have. I have included a link to it below if you think it would help you out. If yours is solid you might try a company called plybo to see what they say about using a solid bamboo ply wood type board
Your chances of finding 8" wide flooring of any kind is very slim. The problem is cupping not warping. The wider the planks the more they will cup. Any real wood product would for sure cup if it was that wide. Even an engineered product like bamboo. Might try a local woodworking company. They would have to custom make the pieces for you. Hope this helps...Good luck with your search!
