I have a concrete side patio that i plan on putting my new hot tub. The problem is that is has a slope for drainage like most patios, but this one is about 2" drop over about 8 feet.
There are no cracks in the existing slab, but I have read that I could make a frame and pour a thin coat of cement on top of it to make it level (2 inches at the slope to a feathered end at the high side).
First of all does this seem like it would work, and if so what type of concrete would I want to use? The regular cement say 2 inch minimum, but there are some other types like a sand topping concretes like they use for shower basins say up to 2".
The spa is 84"x84" and the base is 82"x82" so I would like to keep it as close to that as possible.
Thanks for any advice
