That is where I put sealant. What goes on the end of the cill? Is that where water is coming out (leaking)? Maybe you need to put sealant at the end of the cill to stop the water coming out of the ends.

It is only a short single page piece

On other windows I have put SWS air tightness sealant on the out join between the window and the cill

We had a similar situation. Our problem turned out to be a combination of a manufacturing fault that meant water was staying inside the frame rather than draining out and an installation fault. Our fitters came back, removed the whole unit, dismantled the outer frame, fixed the manufacturing fault, then bunged a tube of sealant in each end of the bottom rail to stop any water getting out the ends. They refitted the frame with proper DPC. All good now

Heehee - when most electricity cuts happen 🙂

We should all build an Edison Generator 😁

What's below that screed? A concrete slab? If you're sure not chance of water ingress and it's already air tight, then just fill with expanding foam or your PIR solution as it's not going to to be a heavy foot traffic area 🙂

On our ground floor we have done as in Nod's picture above. The herringbone in my picture meets LVT tiles in the kitchen area, which orient across the arrows (L to R). There will be a brushed bronze 38mm "rail" where they meet

True

Herringbone 😁

Great progress Susie and David. Soakaway, cladding and ground works still on (one of) our lists 😁

Our waste pipes went vertically (as you'd expect) through the slab and the insulation below it and the went horizontal (with the needed drop of course) to the STP. Yes, we had to cut the mesh/chair/castle makeup to accommodate this. It is normal.

Likely it is such a metal lintel behind those vertical laid bricks. Without removing one you'll never really know for sure, but safe to assume it is there. Will the weight of the pergola be taken by vertical posts and at four(?) corners of the pergola? If so, then the attachment to the wall is mainly to stop it moving vertically away from the wall. Still need to be strong fixings and as long as you drill carefully and jo bricks are broken in the process you should be OK. Fixings can go in the mortar. May be use threaded rod and resin to fix the ledger (or pergola directly) to the wall.

3 years after installing it, time to clean it. It spent about 1 year open to the elements before the roof went on.

Yes

Just what I was thinking as well. A Birmingham screwdriver 😁

No Kelvin, it should have a PZ head. It's malformed 😁

I can recommend Screedmaster SW Ltd. We had the Cemfloor screed. I let them lay the necessary DPM and foam edging. Not as neat as I would have done it but I'm a neat freak. Clean and accurate (level) pour.

Badger, What depth and dimensions will the poured slab be? This may make a difference to what strength of EPS you require (hopefully one of the SE's will be along shortly, and they'll want to know anyway) For reference, we poured a 250mm deep, 137m2 foundation slab with UFH pipes tied to the mesh. Our insulation was the Jackodur Atlas system (240 or 260mm thick), compressive strength of 130kPa if I recall correctly.

@Onoff, think I'm giving that a miss. Can't imagine the smell, as @JohnMo mentions. Think it would need a test first. Each to their own.

Got a picture of what that looks like. All I can imagine is a black streaky mess

Nice job sir.
