Im removing a wall as part of my extension in my stone built house. The walls are about 500mm thick and rubble filled and is the old external wall. On the outside there is no 1st floor on the inside there is a bedroom/bathroom above.
Ive had structural calcs done for the steel etc. However I have a question about removing this wall. Im told knocking through with needles is best however I dont really want to punch through the floors to go above with the needles.
Can I prop the joists with acrow's and a scaffold board on internal and use strongboys on the outside bit or are they not strong enough? my only other thought is to do needles but do them at ceiling height and have the beam lower than this.
Id also planned to drill above the wall and spray in foam to try and stop the rubble and crap falling out when I remove the wall
Appreciate any advice.
