This past week the pool company put in our gunite shell. In the middle of spraying the gunite there was a downpour that was about 0.5 inches of rain. I am now concerned that the strength of the gunite is compromised. They used #4 rebar and the floor is 8 inches thick. The Gunite company website says they use a mixture that is 5,000 PSI, but I am concerned about the additional water weakening the gunite.
If all the rain was absorbed into the floor then my math (38 by 18 pool with 0.5 inches of rain is 210 gallons.; 38 by 18 by 8 inch floor is 17 yards of gunite) is that is an additional 12 gallons of water per yard of gunite. The conversions I have seen online suggest that would weaken the gunite by 150 PSI per gallon or 1,800 PSI which means the final strength is 3,200 PSI.
Am I missing something and should I be concerned?
Thanks
