  1. So I live in Northeast Florida where it is sandy soil. I do not have a concrete slab only pavers. I do not feel safe laying it on the payers since they have shifted through the years and I had to raised them several times. So my choice is a grassy area. My plan is to remove the grass in a 8’x8′ square, frame it and fill with peat gravel approx. 4″ deep. What do you think? I am getting an INTEL SimpleSpa (inflatable) with a 210 gallon capacity (approx weight 1300 lbs in a 57 inch diameter footprint 2552 in^2 at a calculated 0.51 psi) Would that be ok?

  2. I use and would suggest p50 and soul board it’s just foam board and it’s fairly inexpensive any kind would be better than nothing I then just saying the two pieces together with strong duck or Gorilla Tape I also use carpet tape to take the boards to the deck and the tub mat to the foam boards
