Strengthening a Deck For a Hot Tub
I have an 12x24ft deck,5/4 decking with 2x8 floor joists 16oc.
I'm going to put a hot tub on the deck, on one end. I used your DECK LOAD calculator (excellent tool by the way)to add more support piers. I also want want to add more floor joists in the hot tub area.
What would be stronger; using 8"o.c. or doubling up the joists and going up the joists and go 16"o.c.?
