What type of cement?

[Bober78]

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

Why not build a frame so that the low side is 4" , high side 2" and pour some concrete/cement?

They make plenty of types/brands of pour in leveling compound. Get to your local hardware chain (Home Depot, Menards, Lowes) and ask. Make sure you research for concrete because wood is a lot different. Your going to want to score your existing patio and use a bonding agent also.

I would perfer to have a lower one (2" tapered down to a featherd) but i'm sure 4" to 2" is probably better against cracking.

If I did that, i would only need it to be just a hair bigger than the base footprint right?

It is kind of nice to have room at the front of tub for the steps.

Use epoxy leveler. You can feather that to a lot thinner. Google your options. Leave a small amount of drainage slope.
