I'm hoping someone knowledgeable about pool construction can give me some advice.
A local granite company installed a spillover between my spa and pool, they secured it down with silicone. As soon as the pool was filled, we noticed water leaking out of the tiles just below the spillover, a crack formed in the granite, and it is 'floating' on one side (you can push on it and it moves up and down about 1/8 inch.
The granite company says its not their fault, they always install it that way and never have a problem. They blame the pool company for not making a level surface, and say its not their job to make sure the surface is level. My pool company says you always install granite spillovers with thin-set.
Can anyone shed light on what the proper way to install a granite spillover is?
Also, the granite company put a lip on both the pool side AND the spa side of the spillover, and my pool company says you should not have a lip on the spa side because it disrupts the water flow and increases the chances of the water intruding below the granite slab - does this sound correct?
Thanks in advance to anyone that can provide feedback!
