The house I just bought has a 12'x12'x4" patio that I want to remove. What is the best strategy for this? Just rent a jackhammer and go at it? Rent a dumpster for the busted concrete? Can I knock this out in a day by myself? Once its out I plan on throwing in some dirt to level it out and grow in grass. This doesn't seem like too big of a deal, am I naive? thanks.
