But laying 2 layers allows the staggering of joints. Having recently done 2 layers I'd be thinking of having the thinner layer below, as the top one will be stiffer to resist bending under load (if there are any voids). Jablite is much softer and the saw doesn't get stuck in thck boards. But for 50mm of either, a saw is fine. Both are easy with a machine. We had a contractor do the floor. He used a recip. saw and long blade. Fast but approximate. I've been doing some wall stud infilling. It's a pain. I'm using a jigsaw with 4" blade which only cuts 2". Then repeat other side.. so is slow. With a long blade it wanders wildly. I think ideally with pir I would cut first with a jigsaw then complete the cut with a recip. Also, eps makes lots of dust, pir much less but nasty and needs a mask. Another option.. pir has aluminium foil on both faces. It cuts by stanley knife and so for 50mm you can cut both faces and get a snap-off cut... and it ux marked in 100mm squares. Yes eps snaps rather roughly.

What have you been reading? Woke is the go-to term for trump and co for whom it means ' not extreme right wing'. I am therefore woke to them. UK oil would be extracted if it made economic sense. Anyway, It isn't any use for fuel but would be sent across the ocean to make chemicals. Certain parties either don't understand this or choose not to acknowledge it.

Finns are apparently much happier than they are portrayed or pretend.

I'm out of touch so accept the word of @SteamyTea, of course. But I recall a time when lots were being pitched at the new sustainability market. Planners were expecting to see that sort of thing too. They were being sold as gimmicks or to please planners, and in totally unsuitable locations. Then suddenly about 15 years ago there were none being touted. Since then, solar technology has improved dramatically but not, I think, turbines. We've discussed this on here before, and I think the moral was that tiny ones work on yachts, out in the ocean, but still won't boil a kettle. Thinking further, I once had journalists visiting as we had won an award for sustainable design, and they didn't understand that there was nothing to photograph. They wanted a wind turbine. I think that this may still be an impression, and being seen with one would be the only perceived benefit.... unless you are on top of a hill but always in shadow, , don't mind the noise and there is no alternative. Shorter answer: no.

Yes it should have been, unless it got wet some other way. How thick is the screed and what is under it?

over what length? 3mm is the industry max under a 3m straight edge, and the long length makes a huge difference.. not just under the middle, but if you stand on an end, and the other end sticks up, then 3mm max there too. That is the standard for commercial floors, so if in any warehouse or sports hall etc. The floor can slope overall quite a lot though and pass. I've never understood why. I have not checked if there are published figure for domestic floors, but if your vinyl layer is saying it's ok then it prob is.

It will depend on the spec. Some is very thin and would show every ripple. Some is thicker and may have a backing. What will it be stuck down with? It might be enough. It may be better to gently grind than use filler. It looks pretty good. You are needing smooth rather than level.

Agreed it can be perfectly good. A few items have been only mediocre but OK in short term. So great for diy, but may not last. But as a groundworker said to me, if a Titan tool (screwfix) fails in 11 months you get a replacement one. They won't say you have used it too much. My latest thoughts are on robustness and storage. The little battery jigsaw I've bought is good, but the snap-on plastic guide bits aren't going to last. Otoh thd expensive dewalt one I borrowed seemed to be lacking some bits too. And I will buy some plastic boxes.

A Finnish supplier I built for said their policy was exactly that. Let the trees grow another year. Presumably Sweden is the same. Are there other commodities you can do that with? But what creates a significant fall in demand in the first place? The manager was proud of Finnish timber being close grained and straight because it grows very slowly on flat and very cold plains. Since then I see trees on hillsides as straining to stay upright (does it grow lopsided?) and Finnish timber as reliable but miserable.

I think I would design these as distinct units, so that they can articulate without cracking, as the loadings are very different, and an 11m pool structure will be less complex than 28m. The gaps can be filled in with flooring.

Presumably this confederation is only for producers who meet the standards required. It will need testing and inspection for C16. The thing is, we have used about 8km of timber( and most had to be C24, ) so I can't test this supplier. But they were totally knowledgeable of the requirements and issues in real life (drying, milling, straightness, storage) so I'm confident it will be good stuff.

But it is not. It is a very big water tank, and if the ground moves a tiny bit, the slab and or walls could break and it gets very messy and expensive. And you will be indoors now, not outside., so damage and repairs are x3. There are a lot of failures of swimming pools and contractors have gone bust and Engineers had very expensive claims. And some of these are for proper designs: the ground we live on is very mobile. If the results of the boreholes are encouraging then you will save cost on the amount of concrete and of reinforcememnt. If they show poor ground then it really is essential to know that and design to suit. Is it still 27m long as previous posts? that is big and not to be dabbled with. How much do you want it?

Might it be easier to drive the nails right through and leave them there? (With a punch?) Battens aren't strong timber and I'd expect a lot of damage if prising them off. I'm all for saving the material . I recall a tool my dad had which was for this purpose*... about 3" long with a square head and then a taper to a round end for the nail contact. * I doubt he ever put a nail in wrong, but neither did any timber get thrown if it could be repurposed. BUT if anyone knows better than me then listen to them... I've never done roof battens.

I've tried and failed to obtain local timber when C16 is the requirement. So I was surprised and pleased to see that it is now being marketed. At the "future-build" exhibition in London I had a long chat with them. They were very knowledgeable and enthusiastic, and the rep clearly knew all the merchants personally. Scottish timber grows fast and with wide rings. I'd expect Kielder and more southern climes grow even faster. So it is never close ringed and dense enough to provide the stronger C24 timber. But I have never been able to get uk timber because the merchants get in Scandinavian wood for their own ease. I am assured that some merchants will get the UK stuff if we insist/ ask around. And it should be cheaper for obvious reasons of proximity. Plus the carbon credentials are much better, and rather incredibly, Scottish forestry supports 34,000 jobs and GVA is £3billion. If it sold more as structural timber, then they would plant more. They also seemed to agree with my concerns on timber being stored and supplied wet by merchants. They understood all the concerns about dryness and straightness. I guess buying local and just-in-time might help that too. Confederation of forest industries, called Confor. Confor.org.uk Nobody else came to the stand. There were thousands there but the agenda was more about "solutions" and tick-boxing systems. A lot of Chinese exhibitors selling robots incl plastering machines , lots of IT and computer modelling, but also earth bricks and marble. Overall... the future of building is systems and protocols. I couldn't work out what some stalls were even offering, and their staff couldn't always explain either. NB.. it wasn't aimed at self build or small projects.

Everything I'd guess. I'm getting very prompt adverts for things we are discussing but absolutely not mentioning in messages or searches. So that's the phone listening? I bought a watch and there were ads for watches the same day and since. Pointless as I now have a watch. Wood burning stoves discussed... ads appear. And other such.

They should be fine. Drills don't use a huge amount of power. I've got 2A, 4A and 6A batteries. 2A fine for drills and jigsaw, and multitool. and lasts for hours. 6A for the SDS drill/breaker , bench saw, vacuum, leaf blower. ( the latter two still need changing after 20 minutes) 4A generally not my first choice as they are a compromise, so are backup.

I'd say so. Most people just see what they see and won't be aware of the other issues. Filling a hole with concrete and steel is the obvious thing to do so that's what happens. They could be bolted down to exposed rock, use piles as support, include voids or mass materials in lower stress areas, reuse the excavated material include recycled aggregate. But with concrete readily available then that's what happens. Actually I don't know. Maybe other methods are already utilised.

It might not be terrible hard If it is cleaning of tools slops then it will have been very wet and that makes it weak. It is total ignorance... thinking a drain is a magic thing where stuff goes away. Yes the culprit should pay for a solution. I wouldn't want them bodging a half- hearted improvement. It needs a groundworker who doesn’t mind old-fashioned spade work. £1,000 deduction, some released if it turns out to be easier.

I'd be very surprised if there isn't a way. Needs some early collaboration between the parties rather than a linear design process. Having spent a lot of time in such cages, doing qc, I'm left wondering how the steelfixers got out. And how the concrete got to the bottom... how do we know it is well compacted? Doing the site inspections was much easier than the fixers job so it breeds respect for them and the detailer (both the Engineer and their draughts- person)... and my own designing for ease (feasibility) of construction.

That doesn't even happen for gross incompetence with lives lost. To me, the PI I had to pay was firstly an assurance for every client, and secondly it was in case of any inadvertent error by my business or a sub-contractor or engaged specialist designer. It didn't occur to me that we, or anyone, might be incompetent... ie only do what you know and do it well. Part of the training is to appreciate all aspects and know enough that you don't dabble. Eg a surgeon doing hip surgery knows a lot about cardiology but doesn't dabble with heart surgery. Fundamentally a dabbling and overconfident builder or a rogue designer probably goes out of business after a very big mistake, but some poor client is left with the consequences.

What is the context? What is being connected? Materials, and why you are concerned?

Interesting. Does this mean there are three dams of relatively low output rather than one huge one? Like in earlier centuries, having several flour mills along a stretch of river?

I don't know, but would be surprised if the usa has any ethos towards nett zero, or government pressure in that regard. I'd expect the blades could be recycled but that it is entirely a short term financial choice. I was talking to a polystyrene product manufacturer today. All their dust and offcuts get sent back to Austria, where it came from, for recycling...that obv is more expensive than dumping it... it's a choice.

I hadn't heard of that. Do you know why it can't remain as a base?

Having been in the shaft under construction for one, it felt expensive even before any mechanical kit. The land-rover drove us into the mountain to the man made cavern. There may have been 2 tunnels, one for pipes and one for people. Very James Bond.
