mourad

Thank you!

free labor I vote for.

whats your budget? you could rent a cat, a jackhammer, use a sledgehammer.

I will hire a day laborer to do it. I am just wondering if a sledgehammer would work? If so, I will buy a sledgehammer, if it won't, I will rent a jack hammer.

the jackhammer will be easier on your body then the sledge hammer will be and do it a lot faster.

I use an abrasive saw and cut it up in sections then bust it up.
Then we scoop it up with a Skid loader and dump it into a dumpster.
Since you asking it's clear you have never done this before and have no idea what your in for.
Just trying to use a sluge hammer is never going to work out.

How big is this slab?
How do you plan on hauling it away?
Where do you plan on taking it?

This wil give you an idea on just how much your going to be dealing with.

if it's a freestanding concrete pad, i would just use a jack hammer.

if it is poured next to the house foundation, i would also rent a small demolition hammer like Makita HM1214c

good luck

sorry wrong thread

rent an electric bosch brute breaking gun & 2" chisel bit from your local rental store - the apron/vest stores rent 40# guns which means harder work & longer rental periods - the 60# bosch still rules !

if you hear it from a guy in the apron store, be VERY suspicious the mtl/method will work,,, when it time to build something together, they won't answer phones NOR help

I rented that Bosch unit to crack open my basement floor to install a sump pump. It had awesome power, but everything in the house shook.

Few years later, I rented a small Makita to demolish my concrete patio step.

I went with Makita because I wanted a more controlled and accurate demolition to limit the transfer of any vibrations. You are right in that my demo project probably took about 4 hours longer than had I rented the Bosch unit.
