Wall ties and starters

[Will1986]

Hi.
At what point do I need to start inserting wall ties. Below DPC or wait until above. I have 2 courses of concrete blocks and 2 courses of engineering bricks below DPC.
Also do I use wall starters below DPC??
Cheers

Ties every 450 from the bottom of a cavity wall. Whether it's in the ground or above it. But you may want to put ties at the bottom of the insulation to hold it up.

Wall starters above DPC unless you have some sort of whacky design.

Do I have to put a tie in every course of brick/block?

Don't you have plans specifying how to build the walls?

 

[Will1986]

The spec just says to tie in to the existing building

Sorry the second question was referring to the wall starter ties. I have the spacings for the wall ties

With wall starters, there will be enough ties for one every block course and one every three brick courses
