spray on concrete

[scottishjohn]

anybody know if there is such a thing -- to basically spray inside of my granite walls to stick them all together --

Guncrete / Gunite / Shotcrete

 

All the same thing, usually used for geotechnical work. 

 

 

[scottishjohn]

got response eventually from planning  and maybe \\\\\\\\\i will need to keep lower level of orginal granite house 

 so my intial thoughts are stabilize it all -- put a ring beam on top of first floor -then concrete roof  and build modern house on top 

  thinking it could be alot cheaper than having masons in messing about to do the same thing 

 

open to any other suggestions  that will not take off too much interior space

maybe shutter it all and a thin  sloppy concrete wall ?

 or use something like VELOX panels to do the same ?

 think that could be cheaper than flatten and the rebuild original outer facade  on to an ICF or block wall

 now the head will really start to spin

what is that exactly

[Mr Punter]

Was suggested to me for stabilising a river wall.  It was a similar cost to formwork in the end and the finish was not what I was after.

I have seen it used for tunnels as well.

Used to stabilise banks and other structures. 
 

Have a look at this. https://www.gunite.co.uk/gunite/sprayed-concrete/

Seen it done to build a swimming pool

sprayed it on, high pressure 30-40mm hose, small stones in the mix

one man spraying, one holding the hose behind him as it kicks a bit, then they let it go off for half an hour and scrape it back flat.
