How thick is it? Seems like between 6" and 1 foot.
You *could* use a concrete saw, but it is real messy: w/o water, you got
dust *everywhere*; second person could hold a vacuum, tho.
With water, it's just, well, messy, and miserable in the cold. If it
doesn't cut all the way through, you'll still have to break it up.
If there's rebar in there, the saw might actually be a big help. Or you
could demo hammer it, cut the rebar w/ a sawzall or oxyacetylene.

I took out a 9" thick poured wall, no rebar, partially w/ a saw, but when
down, just broke it up w/ the big Bosch Demo hammer. Actually didn't take
that long.

With the saw, tho, you could cut nice square blocks, and use it for
something else.

Hi,

I need to demolish an elevated concrete slab deck. It's 8 by 16 and
weighs about 4 tons.

My currrent thinking is to use scaffolding to support the slab while I
carve it up using a concrete saw.

Do you have better ideas?

Thanks.

Jack
