Chipping concrete with a Hilti

scooby074 · Nov 19, 2009

Does anyone have any experience with the Hilti Rotary Hammers? Specifically, but not limited to a TE 72

I have a ton of crappy tile to lift and i need to chip up a slab to move a toilet and tub for a remodel.

I know the 72 would have no problem with the tile, but what about the slab? Theres about an 8ft run of concrete that has to be chipped.

Im an electrician, so i know hilti are good, but my experience has been drilling, not chipping.

What about the smaller machines like a TE15 or TE25?

Time on the job is important, but not the only consideration. If a smaller machine will work id be willing to trade time for cost.

Thanks

I used a TE-72 to get 6 ground rods in, only took 3 hours. the ground was super rocky too. id say it would be perfect for tile

Thanks

Im really wondering about its concrete chipping. The slab is 6" think about 30 yrs old im guessing.

With a proper chisel, would the 72 have enough power to break it up?

30 year old slab?

Good luck.

If you can get a deep enough cut, I would prefer to cut it out in sections. A 30 year old slab will simply laugh at most jackhammers.

For reference.... I took on a 30 year old slab a few years ago to make room for my garage.

used a Bobcat skidsteer with hammer attachment.

It took me TWO HOURS to get this far....

So I hired a crew to get rid of it. They didnt believe me how tough it was.

8 hrs longer than they estimated it would take... the slab was gone.

They used the same method. And lost on this job, big time. I paid them a bit extra to get the "nice guy" rep, but they lost their butts on this job.

Yeah old concrete is a tough SOB.

worse is theres really no other option besides lifting the concrete. The drain is in the absolute wrong location.

Did i mention i hate houses on slabs?

Edit: Just saw your pics. Damn...

it even looks hard in the pics... the white in it = old tough concrete

The TE-72 is a great hammer drill but it's just that. It will chip concrete but you shouldn't expect it to remove a 6" slab. I would rent a jack-hammer. An electric one will take a little time but should do the job, as opposed to a 90lb pneumatic that would tear it up in no time. Cutting it indoors, even with water, would be a dust nightmare.
