Apologies if this is the wrong place to post.
I've had HTC screed laid in my build and I'm a bit concerned that around the edges of the walls the screed doesn't go up to it. The plumber after laying the underfloor heating put a sheet of blue foam around the edges, and the builder, when asked said that it was for expansion. He also said that was probably why the screed didn't go up to the walls and in the corners. His solution would be that when it was tiled, the tilers would fill in the gaps, and if they didn't want to do it, he would. Seems a bit heath robinson to me. I've attached pictures and would like any opinions please.
Personally I would have thought that he would have to come in and do touch ups with HTC.
Thanks
