The concrete 7'x7' concrete slab slopes and has waves in it. How can I fix this so I can put my hot tub on it?

Build a platform to compensate for the unleveled concrete foundation for the hot tub. It could be concrete or whatever material you like.

If I used concrete how thick would it have to be and how would I do this? Sorry but I am a newbe at this.

I do t think concrete over concrete works because of the curing time. The new concrete won't cure. But a hardwood platform may work, like mahogany. You didn't use a level? Wait for more qualified suggestions from our experts.

Leveling/repairing concrete slabs is done all the time. Preparing the old slab is the key.

I think this is what Tickle is alluding too.

However you have so many options it comes down to your own personal taste and pocket book.

Others are bound to come along with their own ideas.

We did use a level, however were sloping for the grade away from house.

What about building a form around and level at top and pour pea gravel on top of concrete? Do you think this would work?
