Hi all, We're currently renovating our new house. We had our floor levelled a few months ago and it was done very poorly. We had someone else come to fix it and he ended up using latex screed over the top. Invictus LVT was laid and all was well for a couple of months. Yesterday we noticed the floor had bubbled/lifted in the corner next to the patio and front door. Underneath the screed has completely crumbled just in those patches. The man we used to do the floor has suggested that it may be due to water ingress from the external doors and to re seal them. There's no other patches we can see yet. Also in the same areas where the flooring has lifted the screed has leaked through to outside and has pooled on the door trim/garden floor. Does anyone have any ideas of what's caused this and how to fix it please?
Have you had the subfloor moisture tested? Was the slab a new slab? What type of screed was used in the renovation?
Thanks for the reply! No we haven't had anything moisture tested? How would we go about doing that? There was initially wood flooring which was removed. There was a lot of glue residue which we were told would need levelling. Unfortunately I'm not sure of the type that was used the first time round as we had a horrible experience with that fitter. He had the key to the property whilst we were working so did it all himself. The 2nd round was latex. I will try to post some photos once I'm back from work today!
The installer should have the equipment to moisture test the floor before any screeding work etc, if they have assumed all was dry etc or measured that it was, then they should at least moisture test the floor in the area that you are now having issues, they may need to remove some tiles to check other areas of the floor for moisture. If the mositure is from a failure in the door suuround, the floor needs uplifting in this area, the issue fixed, the subfloor allowed to dry and then the flooring can be re-fitted. If there is an issue with the floor in this area not associated with the door surround, then a localised moisture treatment could be attempted but does risk pushing the issue across the floor to an area not treated. The installer should be able to work with you to resolve this issue that at least at the moment seem localised and manageable
