Only for the 1st 3 courses.

Anyone care to calc the loss of 150mm pir with 25mm eps underneath? Cheers.

Thanks all so far! Daft question: If I fill with mass concrete won't that defeat any dpc?

I was thinking to use these st/st helical wall ties cut down to to say 400mm: Did wonder whether I could use standard wall ties set at 45deg on each corner?

I presume it's something to do with stopping the salts/effervescense? Why not do the whole column I wonder?

Playing with some card & glue:

Can't you just have a bottle of Carex at the main sink and wash your hands there? IGNORE everything I've said. For some reason I thought you were wanting two sinks in there!

No more than usual!

Looks like a neat, near dust free install method for fitting UFH in existing concrete floors but guessing the losses downward (& to the side?) must be pretty large without decent insulation in the floor make up?

Slippery slope...Skynet etc

Trying to think of reasons to stay out of the house at the moment! Multiple threads likely!

What all over? Doesn't that affect the mortar bonding to them or do you just paint the faces when laid?

I liked DS as it was a near 100% clone of AutoCAD. Transition time was seconds rather than minutes. So much so I had to wonder sometimes what package I was in. Then though it got quirky, wouldn't run properly on my Linux installs and so on. The constant wanting to "phone home" and verify registration was annoying but manageable. AutoCAD is also a pita the way it recognises a drawing created in Draftsight as "alien" and won't let you edit solids created in DS. Their loss!

So it would be helpful for the OP to know the full build-up.

But what have you then got on top in terms of ventilation gap if any and roof membrane?

Cheap seats here!

How deep are your rafters? If 150mm then 100mm pir max...I think.

Nasty Wickes wood battens on and plumb/level. Quick coat of white in the bit you'll see if ever accessing the pipe/valve to the wc: Ran out of gun foam Will get a can in the morning and try and get it all insulated and boarded.

Don't drink coffee or smoke...body's a temple etc.

Until it's 100% finished I find myself somewhat anally retentive whilst in there. Not to say I haven't thought about it but I get cold feet. Maybe when the UFH is up and running...

I'll have a large doner if you like tonight then video how effective the Geberit/Bernstein combo is at shifting the results...

Reckon I need to come up a good bit with engineering bricks to make 6" above ground! That's about 8 courses if 600mm. Might just do 3 courses then wrap the base 2' out of the ground in a black membrane and just cut it to the eventual ground slope. A bit like a post saver. Made a faux pas way back with the posts. After welding I ran gear oil down inside them so all faces were coated. I then gun foamed the insides. Why I don't know. Means the grey painted face condensates quite a bit. Think I'll paint with black bitumen before doing the brickwork.

It would appear that Draftsight is no longer free for what was a useful 2D CAD program! I've read it had been become a bit of a loss leader to the detriment of other products. I think it's in the SolidWorks stable now. Barstewards!

Don't really like the look of them, too smooth and shiny and they don't match the garage pillars.

Sevenoaks but I'll be doing it all myself and not getting anyone in. Option 1: - 3 courses smooth red engineering brick - F2 bricks thereafter Option 2 - F2 bricks all the way, straight off the concrete base. Mocked up with a few Celcon block. If a DPC goes down not sure on just a strip one the width of the "bricks" or a big one piece one, the area of the pillar itself: I will make a Bricky esque tool that clamps to the 100 x 100 post that you slide up to ensure complete dimensional accuracy and a constant thickness mortar bed. I also thinking about infilling with mass concrete at least up to "Tesco van bumper height". I need to be VERY sure all my ducts for brick lights, intercom, sensors etc are in place beforehand and that there's eps blocks or similar in place in lieu of bricks to be dug out later for the brick lights.
