I have a dog that insists on marking inside the house in a few different places and no amount of training, deterrent sprays, or preventative potty breaks has been able to fix it. It wasn’t a problem until we had a housemate move in with a dog who peed inside the day they moved in and it’s been non stop ever since.

As for the concrete patio, I had a dog door that my only pup at the time could use to let herself out with. The entire space was concrete with a small strip of dirt that had some trees and stuff. I would be gone for work for most of the day so she’d let herself out to use the bathroom. I’d clean up the poop and stuff but the pee was kind of a pain to get up and off and I was really busy for a few months. She was getting walked or taken to the dog park nearly daily.

I assure you, both of my dogs are extremely well taken care of. I’ve spent hundreds of dollars and dozens of hours to try to alleviate the peeing inside problem at this point and pretty much everyone, trainers included, is at a loss for how to get him to stop. But thank you for your concern. I’m sure you would do better than me but I just can’t be as superior a being as you.
