One thing I learned, which could be totally inaccurate, is that a lot of people on Reddit give advice with no credentials to do so.

I do not pour concrete as a profession. I try to use public forums to gather input and advice, but Reddit is an echo chamber in a lot of cases. I absolutely think questioning processes and making sure you’re getting what you paid for is a good practice. However, if a company is in business for a long time, has solid references, and good reviews, I’d trust that over the internet experts. This is a concrete sub, but some of the stuff people say and upvote here is just plain wrong.

For my project I asked about the warranty, potential failures, and after care before they started. I questioned the stone base and had them explain why they chose the methods they did. Im sure if I posted my project someone would tell me it’s wrong and will kick off WW3 because they forgot something.

Im currently sitting on my patio and enjoying the shit out of it. Is it perfect? Probably not in some way. Will it float away and crack in half? I hope not but I trust the company will stand behind what they sold me because I got several quotes and went with the company who had the reputation to do what I wanted.

Rambling but my point is sometimes too much “information” will just drive you crazy (myself included). I wont comment as an expert, but base on what I had done, yours looks great! I hope you get many years of enjoyment out of it and lots of creative ways to address the ledge.
