I am building a new house with an in-ground pool in Charlotte, NC and am trying to figure out what material to use to line the inside of it. I have ruled out PebbleTec due to a large amount of negative feedback about it tearing up your feet. I have also personally felt it in a pool and thought it was rough. My pool guy is now recommending a product called Hydrazzo, though he has never installed it, and doesn't know of anyone in the area who has used it and can let me check it out. I am having a hard time finding information about whether it is a good product. I'm looking for first-hand experience, not just the information they have on their website. I want a smooth finish that isn't slippery and that is very durable and long-lasting. What kind of maintenance is required? I would like to have a non-chlorine pool. I'm looking at ozone. I'm not very knowledgeable in this field so any information would help. Any recommendations other than Hydrazzo are welcome as well. Thank you!
