BLUEBIRD SCREW TIE WALL CONNECTORS, FOR TYING NEW MASONRY WALLS TO EXISTING WALLS.

I recall seeing some kit that is nailed onto the wall, may have been stainless steel.
Cant recall the name.
Any suggestions welcome.

Any thoughts on what can be used it 2 storey as opposed to one?
Thanks

I wouldnt like to use such an item.
It doesnt allow for differential settlement of the new build versus existing.

a tie such as below would be a better installation IMHO.

edit: its the 'satifix universial wall starter system' that im referring to.

The one below is the same idea, it just doesn't come as a kit.
I would prefere these type also.

I had to use a WALL STARTER to add a nib to an entrance that was changed after the block work was completed .It is approx 1m in length and 110 in width and has side nibs which catch the first block , with tongues that are straightened out to 90' to tie into the mortar .The starter is attached to existing wall with plugs and screws.
Available in builders merchants ask any blockie

I would / have use them too.

Proper foundation should not allow any differential in settlement, unless of course its an extension on to a house that has a raft foundation

there will always be differential settlement betwen new and old build.

the old build will have have found its firming base whereas the new build will take time to settle.....

how often do cracks appear between extensions and original builds?
