Hey guys, going to be building a paver patio for a buddy of mine at his new home. The patio is about 615 sq ft with a 2% slope away from the house. I guess my question is, with all of the patios I have built none of them have had a hottub sitting on it, do I need to do anything different with the base where the hottub will be sitting? The hottub is approx. 12'x12'. Either building the base in that particular spot deeper to maybe around 10" or using some type of concrete footing? Or should I be fine with a 6" base with fabric underneath? He also suggested that he wants the area where the hottub is sitting to be perfectly level, I argued that I didnt think a 2% drop would be noticable enough to affect the hottub, who is right? He is a general contractor and is very particular about everything. Also, I'm thinking it would probably be smart to seal the patio after were done due to all the water from the hottub. Open for any suggestions. I know most of you probably have done something like this or something similar, any tips and/or instructions would be helpful. Thanks guys.
