Stupid question

[GrahamT]

Can anyone tell me what would happen if a Wall Connector system wasn't used on a new extension - existing building wall?

If no wall ties are fitted and the brick/blockwork isnt tied in, you will soon notice cracks at the join.

Do you know if any form of tying in was used?

That depends upon whether ANY connectors were used and whether the buildings benefitted from being connected.

Hi

The reason I ask is that I'm having an extension built and they used those wall starter kit things to tie in the new connecting walls. However, when they took out a bit of the existing wall (about 2.5m) that is perpendicular to open into the new area, a lot of the existing bricks that the wall connector was secured to have come away.
You can see the screws and wall plugs sticking through in thin air. I asked whether they were going to cement in the gaps to strengthen it and they said yes.
However, when I got in tonight it's been done and sounds hollow. I suspect its just been plasterboarded and bonded, which means the wall connector is not attached to anything!
Please see pic - I hope it makes sense.
