Wall Starter Kit - where to start...

[Capable Noob]

For an extension using blocks, how low down the wall should I attach the wall starter kit?  Should I start a few inches up from the footing so the first tie is at the first course (there will be about 2.5 blocks below ground level), or is it only required from say ground level, or even dpc and up...?  And is a tie then needed at every course of blocks?

Many thanks as usual.

I usually start them one course of blocks up from the concrete. There are usually enough ties with the pack to fit them at 225 mm centres after that. One for each skin and also a cavity wall tie within 225 mm from the wall at 225 mm centres.

Thanks Canski.  I was thinking along the same sort of lines really, just thought I'd see if there was any reason not to.  Cheers

Don’t forget to cut where possibly between the inner and outer leaves so you don’t create a cold bridge. Below ground you can use bluebird ties screwed in to the existing brickwork.
