Anyone used Dexpan to bust up a patio? I have 260 sq. feet of concrete patio, 5-6 inches thick. I called to order some, but they said it won’t work on “thin slabs”.
I would very much like to avoid having to jackhammer this thing out.

Insurance industry research shows that stout roofs, strong windows, and metal connectors can help protect houses from high wind, hail, and hurricanes.

You are going to have to dispose of it somehow as well I would guess.
Bobcat, big guy with big sledge or a jackhammer and a dump truck. One day or less you should be all cleaned up and back to normal.
It might work on a slab that thin, but then again it might not -- you're close to the limit. The cost of the Dexpan is no big deal, but you're talking about drilling an awful lot of holes to get manageable pieces, and if you drill all the way through the slab it won't work very well at all.
As inexpensive as the stuff is you could try it, but I think there might be a cheaper and more reliable way.
260 sf 6 inches thick isn't much concrete. About 5 cy, or 130 cf, no more that 9.5 tons. One dump truck.
If you rent a 14" wet saw with a diamond blade you can get about a 4" deep cut. As long as the rebar or remesh (if any) isn't too close to the bottom this will reach it.
After you score the slab you can either whack it real good with a maul or just grab the corner with a skidsteer and lift. It will break.
Skidsteers are cheap to rent, you might even find someone local with a two hour minimum charge.
Load the pieces in the dump truck or dumpster and you're done.
I've used a lot of Dexpan and removed a real lot of concrete, that's how I'd do it.
why not get a very heavy truck to back over it
Hey, thanks for all the responses. The slab is in a backyard, I cannot get a bobcat in. Maybe I will try some dynamite.
Before you go blowing things up =), I'm sure there is someone in your area who needs the work. If you're anywhere near Chicago I'll do it for ya. ;-)

If it's inaccessible like that the wet saw and a big maul really is your best bet. Just cut it up into squares that two men can lift and put them on a mason's cart.If you jackhammer it you'll need to do something with all those little pieces. Contractors call me for that regularly until I retrain them.There is no worse choice than jackhammer and shovel.
Man, that is a great idea.It works whenever I don't want it to, that's for sure. All he needs to do is call me, tell me he has a delivery at this address, and that it is very important that the weight of my truck does not crack his slab.I'll fire up the tandem, drive it over there, problem solved. <G>Darn shame this is in his back yard with a yard wall. We'd be done already.
Oh come on. bust that sucker up. You the man!
I got some Dexpan anyway. It took about 3 days before it started to crack-I had actually written it off at that point-but the product does work on thin slabs.The effectiveness/efficiency of using this product on a slab is questionable. They recommend a hole every foot, that is a lot of holes, very, very boring (no pun intended), and also dangerous(using a big drill).It is cool though to see it breaking apart though.
Well then I retract my offer. You done went and took all the fun out of it. Now it's just luggin rocks around, don't git to break nuthin.~ Ted W ~
