Evening Folks, looking for some advice. Been building a 4 bedroom detached since March 2020. On the pre-planning conditions it stated we use a gas membrane compliant with CS2. I have used this all round the perimeter and above the engineering brick. However, I have used 1200 gage visqueen above & below the insulation and pinned the underfloor heating to it and lapped this onto the perimeter/gas membrane. I have found out this evening that I must get a Geologist to do a site survey in order comply with the pre-planning conditions (basically to check the gas membrane is correct)…. And pay £500 for the pleasure. I have a concrete pour happening Tuesday at 8am and the chance of me getting someone out is slim and if they do come I’m presuming it’s going to fail? I’ll also have to take back Up the underfloor heating and start the process again using gas membrane which doesn’t come cheap! please note - The gas trace was very very minimal. On the planning, we initially said 75mm scread for floor level but since I have changed to 100mm finished/polished confrere floor, does anyone know if this has any benefit to me given the above? any help/advice would be massively appreciated! thanks

Hi, Need to think about the vapour barrier soon - the options seem to go from Visqueen up to far more expensive Tyvek airguard etc. The price of the latter scares me, so I'm considering using Visqueen - does anyone know of a good tape to go with it? What about tapes designed for dpm? Thanks CC
