You're right, the screeded floor is level. I need to work that one out. The tiler said he can get level correct for the water to flow to the drain. I'm meeting him tomorrow so I'll ask him how.

Thank you. I didn't know the vertical trap linear drain was available on the market. Quite dear though.

Hi Our first floor has UFH and is made up of 50mm screed, 25mm insulation, 100mm infill concrete blocks B&B. The entire floor is screeded including where the shower waste will be placed in the wetroom. The wetroom has UFH but not where the shower waste will be fitted. The idea is to cut the screed to fit the shower waste/drain. The waste pipe will run underside of the FF floor (within GF dropdown ceiling to external wall). I was considering the tiled linear wetroom waste like the attached. However, these have horizontal outlet pipes, which has put me in doubt that they may not be the best option. This horizontal outlet pipe doesn't drop down enough to go through about 175mm of concrete floor. Is there an alternative product? What would be the best way to approach this? Some of these linear waste pipes are ridiculously priced £250+ (even so some at around £375) others are around ~£70. Any recommendations? Thanks

Apologies for late reply. I tested stixall extreme power on mf, wood and concrete block. Solid stick. Test 1 - used a piece of mf (had a tiny ~1mm lip on the adhesive side too). Applied stixall and placed it on top of the concrete block a brick on top of the mf to hold it down. Test 2 - used an even smaller and thinner piece of mf (quite flimsy compared to above). Applied stixall on one side and placed it on top of the concrete block. This time I didn't put any weight on top of the mf piece to hold it down. Test 3 - used a piece of wood and concrete brick on top of it to hold it down. Left it to cure overnight. All tests were successful, very solid. Only test 2 had a little play and I was able to see the clear adhesive between the two materials. This was probably because there was no weight to hold down the mf. It was still a strong grip. In all three tests, I could pick up the concrete block from mf/wood. Thank you.

@crispy_wafer yes, UFH pipes. @saveasteading thanks

@nod did use timber or mf? Time to buy stixall extreme power test tube. They claim it sticks metal and concrete.

Thanks @Russell griffiths What do you think about using dustproofer and hardener on the screed and then using the stixall extreme? Thanks

Hi We had 50mm liquid screed poured a couple of weeks ago. We now need to build metal frame stud walls to make bathrooms. What would be the best option to attach the metal frame to the screed? Option 1: Adhesive - What would be the best adhesive to stick metal frame to the screeded floor? Option 2: Lay concrete common brick 65mm (without Frog) onto the screed and then screw in the metal frame to the concrete common brick. Thanks

Hi We will have two manifolds on the GF. Does each manifold need a separate flow and return from/to the boiler? Two flow and two return pipes from/to boiler? Or would it be just one flow and one return with a T near the manifolds? Thanks

Thanks

Thanks @nod Is that 3mil before or after skimming? Thanks

Hi all, We have a 120mm (tape measured) stud partition (70mm MF with timber inside, 2x11mm OSB sheets, 2x12.5 plasterboards = 117mm). Not sure what I should allow for skimming, probably 6mm (3mm either side). Can someone please tell me what depth of door frame I need to order? Thank you

Thanks

I've managed to read through the guidance. I agree EPC is not required for a self-build. I can provide the evidence to prove the house is a self-build (paragraph 5.14): • proof of property ownership (eg a copy of title deeds, contract of sale) • documents confirming you received a self-build VAT exemption, self-build loan or mortgage • an invoice for substantial structural materials or labour (eg foundations or timber frame, smaller works such as re-wiring or kitchen-fitting will not be sufficient) • self-build insurance • copies of bank statements • trader and builders’ invoices or contracts. Property owner So let's see what MCS BUS approved installers quote. Thank you.

This is a self-build house. The attached garage, which is slightly set back, looks like an extension thanks to the planning officer.
