View Full Version : Gypcrete cost?

Anybody know how they price gypcrete installation? Do they go by sqft poured or cubit feet pumped or a combination of the two? And does anybody know the price range?

I know I won't be installing it, leave that to the specialist but just doing some research for a GC.

Large interior concrete floor that needs some major prep work before tile. Going to give a bid to float it, but it may start getting above 2" thick in some areas due to raised exterior sliding door tracks and a existing slab that has some 3/4" sags in the middle of the floor.

And it is in a condo over 6" thick poured in place slab on the third floor. So maybe lightweight concrete might be a good choice in this situation.

Stay far away from Gypcrete.

I have Gypcrete bids here in MN. They bid by the Sq. Ft. and it is $2.33 per. This is for 4500 sq. ft. at 1.25" deep and they are coming from 150 miles away. Then they will always have a "special sale" nor promotion etc. that knocks off 10% or so. Lots of salesmanship in the gypcrete world, at least from the name brand guys. Have talked to others as well who say they "can do better than that" on price. One problem with it, keeping prices high, is the proprietary mixes that Maxxon and USG have, their limited installation options and the equipment they have to get it in place.

My local concrete contractor can get a multitude of lightweight options from the local mix plant and beat the Gyp guys by 20-30% depending on the mix. Your situation over there in the sunshine will likely be somehow different, however.

Gyp guys say one can tile right to it. Sounds like a bad idea to me.

Seems like maybe you are going to be bidding against Gypcrete as an option?

To state the obvious, adding 2" of anything (gyp, light, or heavyweight) to a slab on the 3rd floor is gonna be heavy. Tile on that too?

Mark,

Yes tile on that too. I am bidding the tile and making the floor prep a separate item.

The $2.33 for gypcrete in your area included material?

I am hoping they can get the door tracks lowered. Then the thickness of the mud would be more like 1". The sliding door tracks bring the finished floor height up 1 1/2". If I have to put 2" of something that is not a slab on grade I will get a structural engineer to sign off on it.

I'm a little leery of gypcrete, but if that is what is used will go with membrane first, will not be thinsetting directly to gypsum floor.

This is for 4500 sq. ft. at 1 1/4" thick Thermacrete from Maxxon (for radiant floor) placed. They also provide the primer for it but do not place the primer at this price.

Good call on the engineer. I'd say require that no matter what. At least put a disclaimer in your bid or request a sign off.

Seems unwise to add that much floor just to accommodate some door tracks. There must be an alternative to that.

I would think some kind of lightweight would be the way to go for this job. gotta prime it to get it to stick I suppose. Either way, I think you will be putting membrane on because your topping will be variable thickness and more likely to crack over time.

Could use Bekotec and make up the difference in height with foam like in the video on Schluter website? Or- SLC to get it flat, foam and then mud bed?

Thanks Jimbo, never did that job and have managed to successfully avoid tiling over gypcrete since then.

So with gypcrete how does it work with control joints and perimeter expansion joints? Same rules as mud? I don't see either one used out here. I asked an architect on a recent project, he said they like to pour it right to the gwb for soundproofing.

I have always made every effort to divorce myself from any gypcrete floor i set over. A liquid anti fracture is a good way to go...usually a primer is needed, so a membrane that accepts that is a good thing. There has been some talk about the compressive strength due to the lighter weight fillers being used.

Lightweight is a waste of time for anybody who's good at floating floors with dry pack. :)
