Up and over doors are always draughty, plus single skin walls it is going to loose heat as fast as you put it in. Main problem with a workshop is condensation. I have lathe, milling machine, big table saw etc. so I have 2 oil filled rads with thermostats set to keep temp around 10 degrees. Then a fan heater if it’s cold and I’m working in there.

At 4mx4m you do not need piers, the wind loadings are pretty small unless this shed is in a particularly windy location.

Hi and welcome. Every journey starts with a single step

Turn taps off, hold ear to the pipe and listen, then get someone to turn a or some taps on, if you hear the flow it’s water. If not then probably gas.

Octopus fitted a smart meter when I wanted 3 phase, it hardly ever connects tho so pretty pointless as I have to send readings in

Go with a couple of scaffold boards or whatever you have laying around. I have a motorbike ramp and the ends are too narrow so it rocks over easily

Is that a throne?

Go on! We dare you

Difficult to be specific but the top pic looks much older than 70’s bottom pic def appears from that era.

12t machine I bought last Xmas with a leaking drive hub, luckily bought it as a toy. Replacement drive hub £2200 but 11 months wait time so it might be running early next year. But worth keeping an eye on EBay earlier this year picked up a Sany 1.6t machine, full cab, 2017 and only 650hrs on it, as new condition with full paperwork for £12500 plus vat…. And it’s a great machine

Pedestals can be on a slab, placed on pads or even cast as pad and post. a raised pedestrian area is 5KN/m2 so very low ground loadings. curing time, allow a week to be on the safe side.

Yes! Laminating greatly increases the structural strength, torsionally stiffer, bending greatly reduced and splits/shakes are limited to lamination sizes.

Well done, yes trim the edge insulation but never hurts to keep a DPM upstand, it can go up behind plasterboard, plaster and skirts etc. stops any spilled water going where it’s not wanted and adds adds air tightness around the perimeter/through stud walls etc.

We have 150mm concrete in our workshops and regularly put down 20tonne+ point loads

Oh yes! Whenever I see them on EBay I always send a message saying yes I will take it … same message comes back that it is presently in Edinburgh but they will bring it to me after I pay. On one I said I was in Edinburgh at the moment so happy to collect and pay cash …. No response.

Hi and welcome

Looks like tile on top of bitumen, probably shrunk back from the wall over time. Filling with foam or flexible sealer will be ok. Grippers really should have been glued or drilled and screwed on that floor.

As above! If this isn’t an outside wall then extra caution is needed

Looks and sounds like damp walls and could well be a chimney leak. If the skirts are wet then you might as well pull it off especially if plaster has detached. As the patch looks quite even I would guess at water falling down a cavity and splashing rather than seepage through the wall. What’s on the other side?

I think you are right, pull it out and insulate properly if you don’t need it.

Yes, the compound is always going to break up on a flexible floor. The T&G is the ideal surface. Might need to go back around and adjust the screws to get it level but levelling compound isn’t the answer. the plywood could be kept but you still need to level what’s under it

So you have some thin levelling compound over 4mil ply over a floating floor over PIR? It’s going to flex and destroy the compound. can you ditch the compound and ply?

They have to make the wind somehow

The thermometers are useful but no substitute for thermal imaging

Very few good machines at the right price at the moment. Shortage anyway and weak £ meaning loads of plant being snapped up and going abroad. if buying ‘cheap’ be aware of potential repair costs, track motors and drives are like rocking horse Pooh and a slew block will cost a fortune.
