Need some advise on a problem floor. The sub floor was supposed to be below 75rh Ive been told, and had 2 coat dpm and stuck to the concrete. The guys that fitted it butted one end up against the tiles and the other tight up against the original wood floor. The whole floor has cupped and started to push up off the floor lifting the skirting off the walls. It is fitted tight up against existing wood flooring in 2 joining rooms, these havent been affected at all but they have been installed on battens. I will be lifting it in January so I can give more info on the subfloor prep. last time it was fitted(and came up) it was all faced fixed direct to the concrete. Its a very expensive wood plank and they are hoping it is salvageable. If the sub floor is put right could it be re installed and sanded?
got any pictures? When you say cupping you mean the planks are cupping as in like there rolling up ? not that there is not enough expansion and that is lifting the floor? As in 'B'
yeah its cupping but I think there is an expansion problem to, I can get some pictures next week. Think the membrane was broke in the utility room next to this hallway as there is a hole in the subfloor leading outside for cables.
measure a plank across its face accurately also. I mean to the .0 of a mm. Then compare this to what the flooring was milled to. Try and find out what the moister content was that the flooring was dried to also. (manufacturer)
Thats gonna be hard because the guys that installed it have done a runner, cant get hold of them any more. Its been like it over a year now. Its a multi width board, theres 4 or 5 different widths not sure if it was even cut down by the fitters?
There is another doorway directly opposite that one about four meters across looks identical :shock: Picture 3 is where they have gone up to the existing woodfloor and put filler in and its all been squeezed out
Looks like a few problems caused this balls up, no expansions from what I can see and a large moisture and humidity problem. Too bad they can't be found or me thinks their testicles WOOD be Hammered. :twisted:
Subfloor has to much moister in it is my guess Cant say without inspection. Take it the same useless people fitted the stairs also ?
Probably, I can check the moisture in the sub floor when I lift it in the new year. What do you think about restoring it?
By the time you have planned the planks back flat and removed adhesive etc there wont be much left. Possible but i would guess will be better to replace flooring. Whats so special about the timber again?
Well its 22mm solid French oak, and in multi width and they have paid for it twice already so throwing this lot on the fire is not a nice prospect. its been left like that for over a year now but does need sorting out.
To match the rest of the house, Keep getting asked for french oak. I only know of Panaget but they dont do a board like this one. not sure on the price. It was a expensive job as it was all put on battens(apart from that hall) screwed throught the face and the hole capped off with the oak. each plank is fixed at the top middle and bottom. Problem is matching in to the width of the existing floor.
sounds like a bespoke job here, i can't find anything like it in a 22mm multiwidth board, gonna be expensive :shock:
Taken up this floor yesterday, definatly is a moisture problem, hygrometer reads 96%. Hasnt helped that the company that installed it has put 1 coat epoxy (badly) straight on to the bitumen. Not sure if there is a dpm in the screed so talking about digging it up. Ive been speaking to Sika and they say they have a product that can be used over the screed, has any1 used it before http://www.epms-supplies.co.uk/admin/pr ... EpoCem.pdf
Doesnt look like it can be saved really, got a company near me that make bespoke floors so think I will get them to make up the new floor
That looks terrible, the ridges on the glue haven't even made contact with the wood, the floor must be very uneven as well. It's amazing what moisture can do to a timber floor
