I've just been to check the prep on a job I'm due to start on Saturday, my customer was supposed to be having the polypipe overlay UFH system fitted in the kitchen/utility prior to new floor being layed then new kitchen fitted. The UFH was to be fixed to the pot and beam subfloor then I specified that this was to be overlayed with 6mm backerboards then the tile was to be fixed using BAL single part fastflex ( This spec was given the ok by bal technical ).
I arrived at the job to find that the polypipe UFH had not been used, instead 38mm batons had been fixed to the pot and beam floor at 400mm centres between these batons were fitted insulating boards then foil trays for the pipes to sit in. Further insulating boards were then sat between the pipes, all this was then covered with 18mm wbp ply screwed to the batons. As soon as I stood on the floor from entering at the patio doors I could feel a fair amount of deflection, although this wasn't the case for the whole of the floor most of which was pretty solid there were areas especially at the joints of the ply were there was a serious amount of movement. I have a few solutions in mind but any suggestions would be more than welcome.:mad2:
