just to clarify, a 600 wide trench for the cavity wall side of the cony, but the other two walls wont have a cavity as there full height glass pannels and only sit on one brick (about five courses high), so do these still need a 6oo wide trench ? its just alot more digging as im down to 800 deep at moment and have just hit decent ground, so it will be a fair amount of concrete to fill em if they also need 600 width rather than the 3- 400 i have now.
thanks once again.
