First fix pipes before screed

[Sanke]

Hi all
When laying out first fix pipes before the screed is laid how do you guys advise fixing the pipes ?
Ordinary pipe clips secured in concrete blocks between floor beams ? Or is there a recommended method ?
Thanks

Pipes shouldn't be laid in screed unless they are ducted or plastic pipe in pipe system. Pipe in pipe system nail clips. Copper standard clips.

Builder wants to just use felt lagging as that is what he has always done ! Pies will be laid for heating as well as hot/cold

walk away!

far far away

Doesn't comply with the water regulations regardless of what he's always done. Be wary as any comeback could be laid at your door.

should be layed in sleves, or ducted!!

Never use felt lagging in concrete or screed with copper pipes .. it gives off ammonia when wet which is fatal to copper might last a year if your lucky. Don't walk RUN!!!

copper will need to be covered in insulation tape minimium. Pipe in pipe would be a better option, especially for the hot and cold.

we use a bit of strapping to keep them down the galvanise strip with holes in sometimes called pattent band last few jobs theve plasted first and we had the rads to fix pipework to

if its only having water it the pipes, then use hep 20 or another brand of plastic barriered pipe as it doesnt react to the chemicals in the screed. also insulate them first with lagging then clip them down. laggin not only insultes the pipes but gives it room for slight expantion when covered in the screed and prevents cracking.

iv also made clips out of flattened copper pipe before to suit the width, which you can drill a hole at the sides for the screws. just shape it around the pipe. btw foam tube lagging is what i i use

also avoid joints under the floor with plastic pipes

also avoid joints under the floor with plastic pipes

joints in any pipe should be avoided when buried in screed not just plastic imho

goes without saying i suppose, but you cant solder plastic lol
