Hi All,
After a week of channeling out a solid floor and laying Polypipe it's time to fill the channel back in. The plastic piping sections are in plastic conduit and T joints/elbows are outside. When testing the heating for the first time the main 10m run appeared to expand and the previously straight runs of piping formed S shapes within the channel!
Clipping the piping down isn't an easy option as the channel runs close to the DPM in places.
Before we go ahead with the permanent option of pouring concrete in I wondered if anyone had any comments please, good or bad? I've read that the runs should have no joins but with 10m being the main run and T'ing off for rads and rooms it's unavoidable. The concern is what will happen to that expansion once it's set in concrete? Some people have said it'll be fine but I'm just looking for some reassurance!
Many thanks in advance,
D.
