A country or nation using its resources to benefit it own people? how dare you ? next you will be suggesting politicians and governments should do the best for the people too.

As above, also roof pitch. Steep roofs shed water quicker and this can hit an half round and go up and over other edge

Why would a man-made slate require different fixings? Many are slate dust in resin so are just tougher, longer lasting but more uniform

Agreed

The builder is talking crap, no way would they be able to do that and get the same compaction and layer to match the original. you have made sacrifices to accommodate their error, instead of money changing hands go for something additional as compensation, patio, landscaping etc.

The floor finish would be a better insulator than what’s under the pipes so nearly all the heat would be lost to the block and beam which would suck heat away

About 4 years ago my daughter moved into (luckily renting) a brand new 4 bed development house …. Unbelievably bad quality, insulation was thrown into the loft space, plumbing was forever leaving, flickering lights and appliances due to loose connections. At least they didn’t need the lounge concrete slab breaking up to get to the foul drain like next door. just bought her a 50’s council house and she immediately noticed the difference in build quality .. walls don’t move when you close doors, can’t hear the neighbours talking outside and she says it feels so much warmer

Breaking/digging up a slab is never going to be great, much better to get around the problem with additional above ground works if the slab/DPM/insulation is all good

I reckon it will go ahead sometime in the future when people realise that this would give us access to a lot of low cost gas and the alternatives are not working out.

Nothing wrong with digging out and digging again on the right line, strip footings should only be taking vertical loads so not relying on sideways compressive strength of soil etc. Moving a trench into previous backfill is a big no-no and you would need to increase depth of trench to get back to solid ground

Self build or house builder?

What was used to fix the aqua panel, I was asked to look at an install causing smoke and fumes …. Cement board had been “fixed” using solvent adhesive, silicon! And packed out with bits of MDF ?

Just how it should be ???

That’s is just begging for a @pocster comment

This gives you some suggested values. https://www.vent-axia.com/sites/default/files/Ventilation Design Guidelines 2.pdf volume of property is found by multiplying floor area by height to give cubic metres air. multiply this by air changes per hour ACH

Ground transformers are expensive due to the compound or “shed” to house them plus they are much stronger construction. overhead requires poles but the conductors are much cheaper per metre

As far as I’m aware and understand, once the process is in the hands of the conveyancer then both parties have given over their rights and designated the solicitor etc. As acting for themselves so an exchange of contracts is in effect a binding change of ownership

No, air changes per hour is the number of complete complete air changes in the property or room… if volume of building is 100 cubic metres and 2 changes per hour required, then ventilation system needs to be 200 cube per hour minimum. or you need to heat/cool 200 cube per hour to maintain temp

Internal walls connected to the outer skin would need to be included in heat loss, but internal walls on an internal skin are not a thermal bridge

That’s my tea sprayed over my desk!

Too many variables to answer, where is it? Weather conditions etc. Access? Who will lift the materials etc etc. Best bet would be a couple of local quotes

Only the other day I was wondering what had happen to Zoot and heating-gate

Doubtful anyone else will ever notice. You are too close to the project so you see everything, don’t allow it to eat into you.

Yes they are designed for a maximum deflection but Nick is spot on regarding bounce. Pozi’s behave very differently from solid timber or I beams in that the “broken” web allows top and bottom cord to act like elastic as opposed to deflect and return

I cannot get the link to open so can’t see the item. if you can tile around something, you can usually slate around it too as slate is much for forgiving and trimmable.
