We are trying to replace a drainage pipe that runs under a concrete sidewalk leading to the house. It's 30 years old, and digging it out is seeming nearly impossible.

Should I rent a jackhammer?

Are they difficult to use?

Thanks for your input.

I'd rent a gas powered concrete saw before I rented a jackhammer. You could also use a jackhammer to breakup channel you cut out. I'd just give it couple licks with a sledge hammer though.

When cutting channel in sidewalk be sure and cut straight parallel lines so the repair looks neat as possible.

Make sure you exhaust your options on digging under the sidewalk first. It might be a PITA but renting a saw, cutting concrete and repairing isn't an easy time either. Not to mention you'll probably always be able to tell there is a patch in the walk.

For the cost of renting the equipment and the hassle of doing it yourself, you can probably grab a day laborer and a shovel.

Concrete saw, sledge and big pry bar. Unless you are taking the entire thing up, then you want to rent a brute. They are easy to use

jackhammer is fast, but it is grueling (and dangerous) work. if you get one, be sure you use safety glasses, earplugs, padded gloves, and protectors for the top of your feet.

The patch in the concrete will look terrible if it's that old and you are pouring new to replace it. Get a corded drill and the largest and longest paddle bit you can find and attack it from both sides. It's not that difficult.

Concrete saw to score lines and a mini excavator with thumb to remove cocrete section
Then use mini excavator to remove old pipe

Work smarter not harder
