Wall tie isolation and install

[@GMTpointingspecialistsltd]

I got mine from tool station or screw fix I go through 3 or 4 a year
Keep up the good work

I have a local friendly rival called Coastal wall ties and repointing.
He has developed a wall tie locator as you can’t buy them anymore.
It has a lithium battery I believe and has multi function settings for led with or without sound and a vibration setting, sort of like a small paddle.
Cased in rubber and is shock proof and waterproof.
It is by far the most excellent purchase I have made, I have let him know I’ll post a demo video of the VA2 locator soon.
It has pin point accuracy.
Made my life a lot easier

What foam do you use to surround the corroded ties?

[@Southpoint2019]

I use any foam which is IP rated so anything that is water resistant or fire resistant

[@josefhealan712]

Would isolating the ties with foam cause any issues with bridging the cavity? I'm presuming it's done to arrest any further corrosion? Thanks

[@Southpoint2019]

@@josefhealan712 no because the foam can’t possibly reach the inner skin.
It doesn’t expand that far horizontally like insulation would.

i have been doing wall tie replacement since 1986 and i don't carry out any wall tie replacement to any face brick properties because if the joints are very small you cant isolate the existing wall ties properly

[@Southpoint2019]

I know the situations you mean.
In that situation I just remove the brick and either drill the tie out or bend it downward
