Hi all
Working on my extension... concrete slab is down, and the builder has put DPC polythene over the floor, then his 100mm of Celotex insulation.
On top of that goes the screed.
I have a hot and cold feed to the kitchen sink and ground floor WC to put it.
He wants it run under the Celotex cut in a groove, because their is underfloor heating pipes going all over the top of the Celotex.
Problem is.. how can I fix the pipes? I can't drill the concrete slab for clips as that will make a hole in the DPC.
Using 22mm copper with felt insulation should make the pipes quite sturdy when they are laid, but the run is 6M and I don't want rattling pipes.
The gas man is coming out to lay a copper gas across to the fire later this week, and I believe the plan is to do the same for that.
All I can think is to make sure the grooves are cut in the insulation as a neat tight fit, with the felt pipe insulation helping to hold them still.
Once the screed is in place, the ends of the pipes will be solid anyway.
Any input welcome!
Thanks, Steve
