Cut away more material so you are putting a decent sized lump back. Soak and then prime the existing with cement slurry (unless you want to go and buy some SBR). Use sharp sand and a nice strong mix say 4:1 and keep the repair damp for a few days.
Break up the rubble: good for the environment, good for the wallet, good for the waistline. Bricks will shatter quite nicely if you sit them on something solid so the energy stays in the brick when you wack it
I have an Evolution 10inch. Bought in a blinding rush when old Wickes own died mid job, but very pleased with it.
Was about £200 from B&Q and as I already had a matching circular saw I was confident of the quality. Has laser but I don't tend to use and is single bevel (soft start took a bit of...
BC usually sensible about floor insulation in these cases and it's written into the code that there must be a demonstable payback in IIRC 7 years.
A common solution to the front wall is a PCC lintel set just below ground.
You'd be much better off to put in drawings and resolve stuff before...
Not a lot of heat goes downwards anyway but the further away from an outside wall an element of floor is the less that bit will lose. The ratio of perimeter to area for the floor is therefore used to determine the required thickness to meet code. 70 would suggest a largish floor.
Some subsdribe...
Centre is centre: doesn't matter how wide the timber is unless you are using a spacing stick to set them.
I'm not clear why you're mentioning joists at all: how is the floor affected by roof lights?
I doubt very much if there would ever be enough vibtation to undo a nut, but no bad thing to be 100% sure. If you use a spring washer I'd put a plain washer under it so the springer has a positive bite without damaging paint
You're massively overthinking this: if the units are all in and true then the worktops going nowhere,
Presumably you'll be putting sili round the wall? More support.
A couple of ordinary old gold screws is all you need
Pure unadulterated BS by the builder re the joint thickness
I would suggest however that "way higher" to describe 60mm in the context of a garden wall is rather OTT. TBH there sounds as if there's an element of swings and roundabouts here!!
