Morninig Chaps? I went to look at a job on Friday client wants Herring -bone Oak /Maple with a twin block border.The property is being extensively refurbed with the family living upstairs while the builders are downstairs.Took some readings with the Tramex the floor is bone dry! Really dry readings from .1% to 1.6% at first i thought the machine was reading wrong but i tried it outside & it read saturation point straight away.Now to my concerns the builders have put the set the heating pipes very close to the surface at a guess i would say 10- 20mm the closest. All pipes are covered in Denzo or sleeved with similar, with the majority of these in the entrance hall.I have explained to the client that all these voids need to be filled with rapid setting screed Ardurapid 35 or similar but i am concerned the floor will break up between the pipes & the blocks over time. I have been in the game for a long time but am not too proud to ask for all your expert help & insights. Tony www.ar4flooring.co.uk
if the pipes are between 10-20mm from the surface then yes the compound etc will most likely break up. They are incorrect depth. Walk away mate ......
I would be more worried about what the heat from the pipes would do to a solid floor! That can't be any good.
Am going to see this client tomorrow,she will ask the question what is the correct depth! Does anyone know the answer? Thanks to all
depth depends on the system, you need to refer to manufacturer instructions. Also , as Merit pointed out. You shouldn't be installing a solid product over underfloor heating. Engineered only.
Hi Tony, I had a similar problem where the pipes were too close to the surface. As the heat radiated to the wood floor, the floor lifted in that area. It also dried out too much and started to split slightly. It was the equivalent of laying on underfloor heating in that area. I got the end user to get the plumber to dig the pipes deeper as this was the only way I could repair the job and make sure it didn’t happen again.
Thanks Daniel, I've kicked this one back to the client & she has told the builder i want 40mm of screed on the pipes.I told her that the mc on the blocks over the pipes will be minimal in a short time and that gaps will appear,i also told her that the bond between blocks & screed will be greater than screed & pipes at there origional cover depth.That was enough to start the bells ringing. Cheers PS I'm off the builders Xmas card list! Shame.
