I am planning to move my tub from its current location on a concrete slab to a yet to be built deck off my existing deck. My tub is about 5000 lbs filled.
I am unsure of how many deck peirs to use and was thinking that 6 x 12" piers below frost line depth should be enough but have no mathimatical skills to back that up.
Where can I find this information or how can I figure it out.
Thanks in advance.
