come home from work confronted builders who showed me the ties they were inserting in between cavity's also showed me small fixings which were a y shaped and screwed into existing wall did not seen the best but he said they would be ok returned tonight to find base slab had been poured all outer...
Its 600mm height in the quote it said" 600mm wall with zinc coated wall ties"
and I presume this are inserted as the wall is being built ie in-between the mortar joints and not attached after that is correct unless someone knows of different method?
Builders have started to build a dwarf wall today they have just started building the outside wall single brick so far for my conservatory when I inspected it I found it has no wall ties in the brickwork and is not securely keyed into my existing wall. any advice should I get them to start again.
