Am a DIY novice. Haven't done any wall chasing before. Am considering putting my TV cable into a wall chase - purely for reasons of aesthetics. Internal masonry wall, I think it's 12 - 13 cm in thickness. Am considering doing a horizontal wall chase, will need to be about two feet in length, probably 1.5 - 2 cm depth (to accommodate conduit). What should I use to "close" the wall chase? I've done a little bit of plastering before, using Easifill 60 - will that be appropriate? Or should I use something else? Bear in mind the chase should ideally be fairly straightforward to 're-open' if something goes wrong with the cable. If the cable is in a conduit, does that reduce fire risks? I'm no expert at all, but at a glance, the wall looks okay, no cracks or anything (bought the house recently, it was probably built sometime in the '60's). Intend to get a scanner to check for wiring, etc. Anything else I should look for to evaluate the "health" of the wall? Is there a risk of a horizontal wall chase affecting the structural integrity/strength of the wall? Would it be a problem if either end of the wall chase was left relatively "wide open" - openings 3 - 5 cm in length? Would that increase the risk of damp/mould, etc.? Do "curved" or "diagonal" chases cause more serious structural problems than a horizontal chase?

If you put a 110mm elbow on your roof, I'll come down there and multi-tool it back off. Just "NO!". It'll be fugly as feck.

You could use 2 layers of CF200x50mm thick, either side, bridging both internal and external blocks, which would also close the cavity whilst giving you something solid to fix into. Way overkill but if you want a good standard then that's easy and robust (but not cheap). Other option is to close with masonry, but that would need to be tied / toothed in to the existing blockwork to survive.

Which is?

I never fit lesser than 92mm. Always great results tbh. The Brink 600 out-performs the Z'r and is less money Just fitted one, last week, and about to fit a 2x 600 install in a weeks time.

Hello folks, I was flooded in Jan 2025 have recently re-built my house and I am about to get EWI. I should have taken flood protection more seriously earlier, but that ship has now sailed. Regardless I am about to tank the external of my property, and ideally I want to take the flood protection above my DPC . I plan to use this https://www.newtonwaterproofing.co.uk/wp-content/uploads/2021/10/Newton_HydroBond_2K-Flex_TDS_1.0.pdf below DPC and approx 30cm under ground level and then https://www.newtonwaterproofing.co.uk/products-systems/products/cementitious-tanking-slurries-renders/high-performance-cementitious-coating/ to 'bridge' my DPC and provide some level of flood protection above it. My thinking being that the cementitious coating will at least somewhat breathable. See the below diagram for my thoughts, I would just like some input on this? My DPC is very high currently about 40cm off the ground. I have dug around the entire of the property and opened up the pavement at the front.

You both have the right attitude I think. Eventually. Wild flowers and meadows require "not mowing". And it hadn't occurred to me that I could do my " no digging" at any time or place. I may "not dig" tomorrow while watching tv.

probably end up being about 30-40mm. Foundation is a suspended beam & block floor, DPM, 150mm PIR, Vapour membrane, UFH, slip membrane.

@torre The vapour membrane is below the pipes, the slip membrane on top.

Liquid gypsum seems to get good reviews

where are the family's shoes stored?

I believe approved contractors (to PAS????) can self certify

Yes, all government schemes seem to get defrauded. Horrendous during covid. Imagine spending £500 Billion to no good effect, and actually doing so much longer term damage. And it is our money not theirs, the politicians waste it like water.

Isn't the membrane usually laid below the pipes?

I’ve not read everything in this thread as I’m too lazy, but our back garden is now where the old bungalow used to be and after the demolition it all got filled in and levelled-ish with clay. Was a dried out baked slab of solid ground that pooled water. I rotavated the clay and added 20 tons of manure which got turned in as well. The covered the lot in 100mm-ish of grade B topsoil and seeded the lot. We now have a nice green lawn that wasn’t waterlogged at all this year during the constant rain so I’m happy! the bit to the right of the house will just have some topsoil put on it and then sown with wildflowers eventually.

The interesting thing seems to be, that those works carried out under eco4 scheme do NOT have building control sign off. What i simply cannot find out, is how that can possibly be. Its notifiable work. So how can work done under eco4 not have BC sign off? Of course, its no surprise that such work is generally poor, to put it mildly.

Good. About time they started looking into this. Meanwhile, they wil announce another scheme!

It shouldn't be, if the house was weather- tight. The outdoor temperature shouldn't make much difference. Anything else you can tell us? Do the windows steam up? How long did you have the house before laying the flooring? What is the flooring material? Laminated can be several options. Any chance it is simply a smell coming off the flooring material itself?

Or rather than ply sheet, Add some 4x2 at say 500/600mm centers with the timbers laid so their widest face 4" was up against the sarking giving me 18mm t&g + 45mm timber to go at.

We were told we needed two units but I pushed back as I didn’t want to pay for two units and to pay to install two units and to maintain 2 units with filter changes etc. So the M&E company calculated that if we upped the duct size to 92mm we could use one Zehnder 600 which is what we did and I have no complaints at all.

Another option, I could add some ply board from the underside of sarking (between purlins) just to give the fixings more purchase

How about this one. SFO involved https://www.gov.uk/government/news/sfo-launch-appeal-into-suspected-home-heating-insulation-fraud
