Thread: 6" or 8"

  1. Back To Top    #1

    6" or 8"

    I will start building my inground gunite pool soon and am getting conflicting information about recommended gunite thickness. The pool will be 5' deep at the deepest point with 3/8" rebar on 8" centers. What would you want 6" or 8" of gunite? I know thicker is stronger but is it necessary? The additional cost will be about $1,500. The soil is high in clay content (it does crack with lack of rain). Location is south Texas.
    Thanks for any input.

    Some people with a lot more knowledge than me will come along soon. If it turns out to be a close call, just remember you can't buy the other two inches later. What does the pool builder say about it?

    I am contracting out this pool myself and my plans call for 8". I have gotten several bids and some gunite companies decided to bid the job with 6" and tell me 8" is not necessary. Just trying to make a decision before it is too late.

    You would be much better off going with an eight-inch thick wall.

    Carson:

    My PB goes with 8" on the bond beam and 12" on the floor. Up to you, but I would think - and I'm no expert - that with the outside pressures that will be against the shell, the thicker the better. Just my $.02

    Not only does the soil crack with a lack of rain, when there is a lot of moisture, it SWELLS. Expansive soils can put lots of pressure on structures. Go with what your designer called for.

    It looks unanimous, 8" it is. Not too much extra money to do it right. I know it couldn't be repaired for that if it were to crack or break. Thanks for the advice.
