Strengthening a floor
We are pulling out a Jacuzzi brand whirlpool and replacing it with a
Sanijet. According to Jacuzzi, they require floor strength of about 55 lbs
per sq feet. Surprisingly, Sanijet wants 100 lbs per sq feet. I am looking
for ideas on strengthening the floor. I have access from underneath. I
plan on adding an additional piece of sheet rock on top and screwing it to
the joists. Sistering the joists would probably be difficult because a
portion of the floor is cantilevered but I could put in a bunch of blocking
between joists underneath the whirlpool if that would help. Any suggestions
would be appreciated.
