Demolition Advice

We are tearing out a deck built in the 80s, in RI, US.. and want to put a patio (6-7" step down from the door). And there's this delightful surprise.. a cement slab.

I've never demo'd this kind of thing before. I can assume it's attached to the house with rods? It's 3.75 inches thick and underneath appears to be just clayish dirt.

Should I sledgehammer it? Get a masonry blade and cut it apart? Any ideas in general so I can get rid of it and not damage my foundation? Thanks!

Rent a jackhammer. It'll be a lot easier than a sledgehammer

And hope they didn’t put rebar in there😉

Wear a mask. Concrete dust is really bad for you.

it is unlikely it is tied to your foundation

Any way of building on top of the slab? What kind of patio & is the slab in decent shape?

Something like this:

Other issue is the wood on the side of the house is rotted being too close to the ground. I wanted a drop there so rain can run off and snow can sit below the siding level.

The original contractor's philosophy was: "if it sits on the ground, it's safe and sound!"
