removing insulated slabs

Tubberadora

Helping to strip a house before it gets demolished. Have nearly everything done now apart from removing the insulated slabs on the internal walls, external facing only. They don't seem to be glued but are fixed with the mushroom type fixers. Any idea how to get these off in large sections to make things easier.

if you could locate them under the plaster might be able to drill top of,very lucky if you get them off in big sheets,say 4 inches into wall.

I tried one today found the mushrooms and removed the circular part. That didn't help at all.
Is it a case of just using a sledge and break them off?

if scrapping them crowbar in behind and pull,wear glasses for safety,is it 50mm or 30 mm warm boards?

6-8 maybe in a sheet or lazygit using 4 lol

Do me a favor when you are ripping them off OP and check for mould behind them.
You hear plenty of scare stories about mould growing behind such slabs from random folk.
I'd be interested to see what happened in your case.

50 mm and 8-10 fixers per slab. Are you saying remove the fixers with a crowbar? Don't know if that will work as the slab will give way.

Could you cut out a channel about 3" wide with a osscilater , then get your crowbar in behind the rest of the slab.

The crowbar will just come straight through the slab.

i thought it was getting scrapped as you wont get the sheet off in sections but bits.

If you have the heads cut off the mushrooms the slab should come away unless some other adhesive was used. Horse into it and tear out a section of it to see is some sort of adhesive used.

Its getting scrapped alright but need to bring it out of the house and load it into a trailer. Much easier carry slabs than sweeping up bits of rubble

It will be very hard to get the whole slab off but a way I would user to get it off in larger chunks is to try using a shovel instead of a crow bar. Works really well for slabs that are dabbed on and can sometimes get mushroom fixings to pull out nicely.

The shovel worked pretty well. Although it was some tough work. All the slabs were fixed with mushrooms and glued aswel. My two arms are hanging off me.
As to the person that asked about mould, not a bit and the original shell of house would be 100 years old. Slabs there about 15 years.
