Pad Just
do i need any re-bar or other support for laying a concrete pad for a 7x7ft 6 person hot tub?
I'm planning on pouring a 7x7 concrete pad for a hot tub. I dont know exactly what type of concrete to buy and do i need to re-enforce the 4" of concrete any further. I'm planning on just digging into the ground 4 inches and then filling it up with the concrete. Dont care how it looks because the hot tub will be surrounded by a deck and you wont see the bottom.
My brother and I did this two years ago for his "tubby" in the California Sierra Nevada foothills
We went down to clay (3"), put down an inch of pea-gravel, put up a 2x4 pour frame, suspended wire mesh at half-depth, poured the concrete, screeded and finished the surface
That has lasted just fine for two icy and snowy winters with a FULL tubby. We plan to do the deck this winter, since we have had other projects sucking away money (barn and fencing, irrigation, and a swamp-cooler).
Good Luck !!
