Leveling Concrete ?

[FULL FLEX]

I am in the process of bidding a job. The customer has a very unlevel concrete floor. He wants electric floor heat. The house is octagon and the area in question has 28 large windows facing the south so it is very well lit. Now heres the fun part,,, He has 18 inch polished marble waiting on a pallet in his garage. I was thinking about hot gluing the heating wires directly to the slab and trying to find a self leveler to cover them and correct the floor. Its about 500 feet. Your input is much appreciated

float it, go nuts with water and thinset to burn the mud into the slab with the wire on top and mud the whole thing. I would get the wire done, wet the slab good chicken feed it with modified while you pull your mud. Then you got your heated floor buried in the mud and you can make the floor nice and flat and level for your marble.

Is it slab on or below grade?

"Is it slab on or below grade? "

The octagon house is on a slab. This area steps down. Very wavy, some cracking.

Anyone?

I'm a mud guy so my first response is membrane over the cracks and mudset stone.Have you looked into the leveling spikes,Tuscan or that stuff they sell at HD?

I'm for a mudbed also. How much room can you stand to come up?

I dont do much mud work, but i really couldnt imagine scooting around on all those expensive wires. Id probablly SLc, ditra and set it with TLS but I probablly wouldnt get the job anyway cause itd be to expensive.

mud bed, isn't that what i suggested?

"mud bed" as in portland and sand? Mud bases as in showers is the extent of my experience with mud. I cant imagine getting one flat enough for 18 inch marble. Does anyone have a link to this procedure? THANKS

I've yet to see a mud bed installed by someone competent that WASN'T flat enough. That's one of the reasons for USING a mud bed-- flat and level!

Forget it, I see Im not gonna get a straight answer.

Don't get your panties in a bunch. Let me ask you first-- do you have the room to come up 1 1/2" in elevation?

The guys are trying to work you up a straight answer but you're not providing the necessary information, it seems.

If you do have the necessary room for a mud bed, that's certainly the way I'd wanna go with that installation, too. I suppose you could do the SLC, but it's expensive when you need a lot and with cracks in your slab you'll certainly need an isolation membrane of some sort over it, too.

Could likely save a good bit of dinero and have a better setting surface using deck mud.

My opinion; worth price charged.

If you search you can find massive threads on pulling mud, its easy and its really easy i imagine if you do it the way rob has is doing it in those picture, we pull mud off runners of mud, its a bit harder but once you get it its cake.
