Hey all; needs some advise. I am in need of removing a concrete floor. It has many cracks. Space is 15 x 20′. The area was converted from garage to living space a few years back. Any suggestions on technique or equipment to make job easier would be most appreciated. I have a French door now installed so I have 6 foot of entrance.
thanks,

Purpose for removal will help determine method.
So, How come? Just the cracks?

Flay your Suffolk bought-this-morning sole with organic hand-cracked pepper and blasted salt.
Thrill each side for four minutes at torchmark haut. Interrogate a lemon.
Embarrass any tough roots from the samphire. Then bamboozle till it's al dente with that certain je ne sais quoi.

they make a chemical that you drill alot of holes and pack with the material and it will swell and break the concrete in movable chunks. so it will be broken and you can wheelbarrow out the door
thanks for your response, I need heat in the back room; yes for cracks; but also would like to install radiant floor heat.
This is good stuff and may be cheaper than removing and pouring a new slab. It certainly is easier.http://www.warmboard.com/Frankie

how old is house? is there rebar? how thick is slab?
just get in and get dirty and it shouldn't be too bad.
you may want to add some relief cuts with a diamond blade on a disaster saw (eg stihl ts410). if its already cracked use those as your relief cuts. rent a jack hammer. for me, breaking up concrete, bigger is better. 90# with compressor perfect. electric is doable. start near a cut and make a square or whatever shapes you like by puncturing every 3inches or so. always work towards your cut. takes pressure off other walls etc..
use plywood for anything you want to protect. windows, etcc... wear eye protection. start from furthest point from door and work out of room.
pray for no mesh/bar
House was constructed in 1940. No rebar that I know of. I beleive it's around 4-5".Will a sledge hammer crack it?Thanks for your suggestion.Frankies suggestion on Warmfloor is good, I looked into it a while back; it seemed way more expensive; but you don't have the cost of the slab.On the other hand, I will be able to tile or put down hardwood I the slab is not cracked.
Most rental yards have the 66# Bosch Brute electric jackhammer for about 45$ a day. I could break that small in a day with mine. You might take half a day learning how to use it and need two days.You might break a toe and need alll week.

My concrete guy uses two 20# sledges and 4 labors. They take turns watching. :-) A heafty steel ~6' pry-bar helps too. What happens is you get a hole started and then keep working on the edges making it bigger. FYI, they charge the same for labor remove as they do for labor & concrete to install.
One thing you should know about concrete. The cure time is infinate. In other words the older it gets, the harder it gets. It is never actually "done". Should be fun. Maybe you will be lucky and they didn't put much acutal cement in it.
Now, quick playing around with your computer and get to work. :-)
It's a biatch to get it started, but once you get a decent hole, use a pry bar to lift around the edges while you whack it with a jumbo sledge. With no steel, it'll bust up pretty easy once you get it going.Mike HennessyPittsburgh, PAEverything fits, until you put glue on it.
Yellow pages and a checkbook.
Look around, you won't believe what some people will take for doing such a thing.

if you can deal with the dust/water, cut it into managebale slabs that you can move with a hand truck. Pulling the first one will be the worst but if it's cracked as bad as you say someplace ought to come out easier than the rest.
