Below the grate...is rats then crawling in a concern?

Gulley/grate I think where the existing one is between the black 50mm in the foreground (bath) and the new shower one about equi-distant beyond the drain. I'm going to redo it anyway and get rid of the old clay. Probably lower it too. The white monstrosity coming round the corner is from the upstairs ensuite. Trying to avoid bathroom grey water going directly into soil stacks in case the cess pit backs up!

In & done. I'll cap the end outside and see if it leaks. Taking my chances with the DPM repair: Outside to do too, hope that shower waste isn't too steep: Just had a beer to fortify myself, shower tray former now!

The badger continues it's nocturnal turf cutting:

Polypipe trays as recommended to me by I think @PeterW way back and it's a piece of pi$$ and then some especially with a home made de-coiler: You do I think want a decent thickness of slab using them.

Buffalo board and make your own.

Mesh every time for me.

Polypipe panels?

The foam's trimmed back albeit with some nice hollows. I won't put any more foam on until the drain ain't coming out again! Got to make good the DPM. This is the one atop the EPS layer. I reckon just a line of CT1 as I put the drain in: The other side: Tbh as long as I keep the external wall / DPC clear (it was all covered previously by render and a high path) I don't think bridging i.e. horizontally penetrating damp will be an issue and anything "running" should still stay outside the DPM. Fingers crossed!

I did attempt to chamfer the inside edge of a bit of 50mm waste on the lathe Saturday! Just realised why, it was when I was toying with that pvc adapter.

No reason why the US design couldn't be adapted for ours I guess. Different sized Starrett?

No I didn't. Forgot tbh. I literally foamed the wall then "hinged" the cut DPM back up and bolted the Geberit drain in place. I'm sure it would've been OK but I took it off the next day as said. Weird how it remained "liquid" in there though. Maybe taking the drain off allowed air to seep in? I did have a couple of the wife's plastic plant sprayers in there but she keeps taking them back!

One thought I had, are barn owls over there the same size as ours?

My friend in Oakland .CA sent me these pages on building a barn own box I thought might be of use here: http://www.scvas.org/pdf/cbrp/BuildingBarnOwlBoxes.pdf He has a rat and gopher problem which "his" owls aren't coping with though doing a fine job. Mainly it's the gophers so he's just got some traps too. A neighbourhood alert went round as they have a mountain lion on the prowl so he got himself a nature cam. He found where it was getting under his fence and got one photo of it. He's also captured this shot of raccoons trying to get into the owl box: The mountain lion has some advantages as he's finding raccoon carcasses! And I'm worried about a badger digging the lawn up!

For who? Upstairs bathroom, lounge/diner knock through, dormer roof, main roof, stable block......etc. Got another 10 rooms/areas at least that need the "treament" then there's the outside! I'll be around here for a while I reckon.

Well drilling that hole was a mission! My Makita SDS threw a hissy fit (clutch?). Off the nephew's to borrow his, don't laugh, Guild brand SDS he got from Homebase for about £20 on clearance. I was actually well impressed with it. (In Argos for £60 still). THEN my SDS drill bit sheared off in HIS drill! Had to strip that down and remove the offending bits! Start again! Got some patching of the DPM to do. With the Polypipe panels mesh and UFH pipes it was a bit of a pig so the holes a tad steep and a bit oval vertically. A bit of re-drilling and better now: Bits solvent welded together: The "hollow" where I'd foamed behind the DPM was in fact still wet foam so when I took the wall drain off to do the pipe it proceeded to expand to the point I couldn't get the drain back in position! Peeled off the DPM and now waiting for it to all fully expand before trimming again: Tided up and went and played under the mower with the lad for a bit. Cutting deck off new belt half on. Beer o'clock now.

Canterbury Tales.

I just had to "borrow" the length of external 50mm waste to the bath (just in temporarily to the drain) to get a bit for going thru the wall to the shower. AMAZED that it is spotless and then some inside. It's had a load of soapy, bath bombs included baths through it. Good call on 50mm way back, have you done this before?

Cut down the Geberit pipe, slipped on the fitting with a bit of silcon grease. SHOULD have left it a bit longer then it would have slipped inside the larger (black) pipe shown here by an offcut.

Didn't come out too bad, bit of a crease and a bit of a hollow by the feel of it along the mid-line but then it was quite thick and deep to do in one go. When "in" I'll poke the foam fun nozzle down thru the set foam and fill a bit more. I'm going to follow @Nickfromwales's advice and go with silicon lubed compression fitting. Going to use the straight coupler that came with it but cut back the Geberit black pipe to get it all in. Going to go with the tight 90 and keep telling myself it's 50mm and it'll cope!

Yep, he did alright with it! Replaced the broken pin 7 on the connector with the unused pin 9. The track side's a bit worn. Tried re-tinning some tracks but not good even with flux. Pcb would be easy enough to remake if necessary.

Dispensed with the idea of EPS behind the drain, it would have had to taper anyway. Spray glued the wall DPM to the black painted wall. Loaded the black painted wall with Soudal foam and folded the floor DPM up against it. Then put the wall drain against the DPM and temporarily wedged/screwed in place. Will cut flush when dry. Then I'll remove the drain, sort the studwork and drill through the wall etc:

Boy's tidied the pcb up: New belts came today but I was playing in the bathroom.

I'll bow to your wisdom Sir. The McAlpine compression straight coupler that came in the box is different sized each end but both around 50mm. Photos to follow. I'll get an elbow like it hopefully. If I'd have read this earlier I could have finished it..... McAlpine do a 2" multi fit I see. Can't see me getting one at any of the sheds this weekend though.

MISSED that bit, there was a lot to read so I just skimmed it! Still.....how about silicon rubber tubing?
