Question for those with more experience than myself when it comes to pools... I have a pool contractor that uses in-ground steel wall shells... from my understanding the bonding permitter would go around the pool tying into the pool in 4 evenly spaced spots as well as tying into anything metal such as rails or light shells. Where I get confused is the shell is floor-less, therefor the contractor pours vermiculite over soil as the floor and then places a vinyl liner over this vermiculite floor...
From my understanding the vermiculite needs to be bonded due to its "porous nature" similar to concrete. Which would involve a copper grid or tying into reinforcement steel... I was told there is no reinforcement steel when this stuff is sprayed
in.
Basically my question is: does the vermiculite floor need to be tied into the equipotential bond even tho there is a vinyl liner over it and the metal wall shell?
Or is it safe with out because of the vinyl liner that will eventually be put over top of
