Can an area of poured concrete be removed?

Yes, but you will need to rent a machine to break up the cement. Then just dog it up and toss. Labour intensive, but doable.

Its a big demolition project. You can do it if your capable of handling demo tools.

You can do it, but this is one of the times I would hire out as it is a rough job jack hammering all that concrete then tossing into a bin or at least moving to store for future use. I am all for getting my hands dirty, but this I would hire out.

I agree hiring out. using a jackhammer is murder on your arms and shoulders.

Cover it with rich soil and plant......you may need a retainer wall .

you could make a raised flower bed on top of it and fill it with soil, or rent a machine to demo. it and remove it, but it a lot of hard work

Hire a couple strong teenagers and give them sledgehammers. I've taken out a sidewalk and an old patio this way. Oh, and make them haul it off lol
