Hi all
Couple of questions regarding DPC. I am building an extension which will consist of a timber internal leaf and blockwork external leaf, I have laid the first course of blocks and im at the DPC of the existing brick built house.
1) When connecting the new DPC to the existing, should I rake out the mortor of the existing wall in order to overlap or just butt the new dpc up to the existing?
2) I will tie the new blocks into the existing wall using a starter kit but do I need to install a vertical dpc also? I see lots of videos online where this step is skipped?
Thanks!
