The Geberit wall drain... Falls are good but I'd like to make good a shallow "channel" where the angle former sat. Maybe 2mm deep. The blue membrane folds out and gets stuck down to the concrete. It's worked out good tbh. Would a smear of tile adhesive suffice?

I'll remember that. My one often cruds up with limescale and overflows.

So do you need non return valves on the mains in to the header to stop the rainwater back feeding into the mains?

So the 20mm high trannie will sit in his 25mm space? How warm does the trannie get? Are there any manufacturer's instructions as to clearances?

Sounds good. Don't suppose you have a picture of something like that?

I've gotten as far as building the gate that slides in and out albeit by hand at the moment. I've trialled the motor and rack & pinion drive but have not fitted it yet permanently as I'm remotely siting the control board. I want to take advantage of the periodic deals Travis Perkins offer on bricks for the pillars. Shown mocked up in blocks here. As the pillars will be part set in the banks either side is there a frost proof rating to look for? Ideally I'd like to get away with having a dpc in the column or if I must then get the footing bricks to match those above. Thinking maybe do the whole thing in an engineering brick?

Cheers. When you say "tape" do you mean the mesh stuff?

Joint tape, scrim: I've bought, been given or scored off site various tapes & scrims over the last 35 years or so. Still got most of it! Not in the least adverse to buying some new but wondered what these are that I've found: The first is seemingly VERY low tack, either that or it's so old it's lost it's tackiness! It is a bit tacky but I wonder if it would actually stick to anything: Then I've a couple of rolls of this stuff. Sticky as Hell but the face is shiny and smooth like Sellotape. What is it? It's like a sticky mesh faced in clear plastic: What then do I then need for my mrpb joint? I assume an open mesh or do I use a paper tape and pva it on? Wickes do a couple of the mesh type for just under a tenner a roll. One's fibreglass. Cheers (And yes, the cooker clock needs resetting )

Was there not something in the sellers Ts&Cs that you as the buyer had so long after delivery to verify the goods? I appreciate with something like an ashp you can't be expected to do that in 7 days or whatever. Or am I thinking that's to do with delivery damage when they say that? Don't reckon I'll have any comeback if my bath pump doesn't fire up!

If he's got the original FIT rate...

Right or wrong, gaps filled with tile adhesive. First time I've ever used the powdered stuff. Too much water on the first mix so binned that. A bit left over when I got it right. Cement like and sticky at the same time! I let it go off and rubbed it with a block of wood. Turning my attention to the other walls and ceiling now. Off to find the joint scrim tape for the pb!

I like my music with such bass that the dust can't stick!

Well that worked:

I can't help thinking how I was steered away from my exotic shower base mix and that seems to have turned out a treat...

See the pic ref soil/sand cover etc: https://www.tlc-direct.co.uk/Book/7.13.3.htm

Sand/dirt then bricks if you like at right angles to the run, widest side down. Better than nothing and it'll get rid of them doing something practical! Swa generally has a UV stabilizer in it.

Nope, she's resigned to "as and when" on that score, she just thinks I'll cock it up.

If you don't want to risk crushing your ducts around your cables then bed in sand or sifted soil. You can also lay old roof tiles etc over the top of that.

Missus wants her brother to do it rather than me!

Just bumping this. I need to get a hole(s) drilled in the ceiling to fit an MVHR vent pre plastering ideally. Thinking something like this: https://www.ebay.co.uk/itm/Heat-Recovery-Unit-Grille-MVHR-Ventilation-Duct-Ceiling-Loft-Void-Air-Valve-4-5-/142386955614? 1) Do I need one or two vents per room as in an in & an out? 2) If two then is it two in the same room or the extract here and the intake in another room? 3) Knowing one or two then what dictates the size I need? Rom volume, use, lpm from Part F? 4) For now I might run it to just a simple ducted extractor in the loft and out the soffit with a view to expanding to MVHR later. ( @PeterW pointed me to a cheap unit a while back) I presume the duct sizes are compatible or that there are adapters? 5) On the sketch above I've not shown the body dryer that sits between the rainfall head (top left) and the downlight to the right. Is there a "good" position to aim for for the MVHR vent? Some general MVHR pointers would be appreciated! Cheers

I have vacuumed the walls... As it's in the bathroom should the PVA be the (more expensive) waterproof version or just ordinary? 5:1?

When do I not listen to you?

'kin hope not!

I feel your pain! My retrofit included digging down and building back up the bathroom floor. The original dpc, shown blue on the inner brick leaf was nom level with the original ffl and there were some damp issues. I put a dpm about a meter up the wall then came down under the 100mm PIR. The solid grey underneath is 25mm EPS and the dpm is sandwiched between that and the pir. The corners what with all the folding were a pig as I had to stagger it over footings I'd have loved to have had a blank canvas to design this out from the start! Your design above, are there cold bridging issues at the base?

So all the gear and v.little idea! The wet room mitre, I assume I fill the joints with tile adhesive and let it go off. On the assumption I then reinforce the vertical internal corners with Aqual Panel "mesh": AND that I'm going to run tanking strip up, as well as tanking with tanking liquid... What order to I do in in? Tanking strip over the mesh? Cheers
