Re: Pool Framing

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I encountered this same problem in late 1998 and presented it to the list.  
The list server archives should have the responses I received.   I had a 90' 
span over the pool, with skylights.  We ended up going with steel joists and 
metal deck and a high quality paint system:  Sand blast cleaning per SSPC-
SP-6, one 3.0 mil coat of TNEMEC 90-97 urethane zinc-rich, then two coats 
4.0-6.0 mil each of TNEMEC N27 polyamide epoxy.

Incidentally, I went swimming at the local YMCA this weekend, and they had 
concrete double-tees with no apparent problems.  Good luck.
